As globalization continues to deepen, international brands are increasingly turning their attention to the vast Chinese market. With the largest number of internet users in the world and a digital advertising market size that ranks at the forefront globally, programmatic advertising, as an essential means of digital marketing, is gaining increasing attention. This article will delve into the development history of China’s programmatic advertising ecosystem, analyze its main players and functions, compare it with the foreign ecosystem, and finally provide strategic recommendations for foreign advertisers entering the Chinese market.

Development History of China’s Programmatic Advertising

Since being hailed as the “Year of Programmatic” in 2012, China’s programmatic advertising has experienced a period of enthusiastic capital pursuit, an outbreak period, and an adjustment period that has attracted industry-wide attention. With advertisers focusing on issues such as traffic fraud and advertising transparency, the industry has gone through a period of calm reflection during the adjustment period to the current refined transformation. The Chinese programmatic advertising market has undergone rapid development and transformation.

Embryonic Stage (2008-2011)

During this period, programmatic advertising began to sprout in China, with many companies starting to try this emerging marketing method. In 2011, Alimama launched the advertising trading platform Tanx, marking the preliminary exploration of China’s programmatic advertising.

Rapid Development Period (2012-2013)

The year 2012 is regarded as the inaugural year for programmatic advertising in China, with a plethora of companies launching DSP products. Google’s advertising trading platform also officially went live in China that year. In the following year, giants such as Tencent, Sina, and Baidu joined the programmatic advertising market, propelling the industry’s rapid development.

Eruption Period (2014-2016)

Driven by capital, the programmatic buying market entered an explosive period. Statistics show that during this time, more than a hundred programmatic buying platforms emerged. However, the market also faced issues like fake traffic, brand safety, and opacity, which gradually attracted industry introspection.

Shuffling Adjustment Period (2017 to Present)

As the market matures and advertisers demand higher transparency, the programmatic advertising market has entered a period of shuffling and adjustment. Companies with outstanding technology, resources, and reputation have begun to stand out, while other platforms face the pressure of being eliminated. Advertisers have started to focus more on the quality of advertising delivery rather than the quantity, with a preference for precise delivery that brings verifiable value.

Main Changes and Trends in China’s Programmatic Advertising Ecosystem

As market demands evolve, advertisers increasingly prefer precise delivery and performance measurement, driving the development of programmatic buying technologies, such as Real-Time Bidding (RTB) and Direct Programmatic Buying. In addition, China’s unique market environment and policy orientation are also shaping the unique development path of the programmatic advertising ecosystem, with the following trends emerging:

• Increased demand for vertical platform advertising delivery: Advertisers are paying more and more attention to the quality of advertising delivery, with a preference for precise delivery that brings verifiable value.
• The rise of Connected TV (CTV): With the increase of CTV users, programmatic TV advertising has become a new growth driver in the industry.
• Improvement of KOL programmatic advertising delivery: Programmatic technology helps advertisers more accurately select KOLs for promotion, achieving systematic and programmatic KOL management.
• Cross-platform and cross-device advertising delivery: With the advent of the all-screen era, brands have higher requirements for the scenario of digital marketing, and cross-device programmatic advertising delivery will receive more attention.
• Enhancement of transparency and industry standards: Advertisers are increasingly concerned about industry transparency, and industry norms and standards are being strengthened, with third-party monitoring agencies and high-standard industry norms playing an important role.
• Focus on brand safety and advertising effectiveness: Advertisers’ focus has shifted from  extensive “quantity” to refined “quality,” with brand safety and advertising effectiveness becoming key topics.
• Integration of advertising transaction data: To improve the conversion rate of advertising and consumer experience, the integration of data generated in advertising transactions, more efficiently positioning the right target audience and the right delivery opportunity, has become the focus of the next wave of digital transformation.

Main Players in China’s Programmatic Advertising and Brief Introduction

China’s programmatic advertising ecosystem is a diversified and highly integrated system, including Demand-Side Platforms (DSPs), Supply-Side Platforms (SSPs), Advertising Exchanges, Data Management Platforms (DMPs), Programmatic Creative Platforms, Monitoring and Analytics Tools, Programmatic TV, and Programmatic Digital Out-of-Home (pDOOH), among other roles. These platforms and tools, through efficient technical means, have achieved automated purchasing, precise delivery, and data recovery of advertising resources, providing advertisers with one-stop services from strategy formulation to performance evaluation, promoting the digital transformation of the entire advertising industry.

• DSP (Demand-Side Platform): A platform that helps advertisers or ad agencies to automatically lock in target traffic, purchase advertising space, control budgets, and optimize strategies. YOYI Tech’s Plus platform, covering high-quality advertising resources from mainstream Chinese media, can help advertisers achieve their advertising goals efficiently and economically.
• Ad Exchange & SSP: Advertising trading platforms and supply-side platforms are responsible for the buying and selling of advertising inventory. For example, HUAWEI Ads, as a newly included platform, covers more than 730 million monthly active users.
• Trading Desk: A procurement trading platform and technology, providing one-stop automated advertising platform services. YOYI Tech’s OneDesk is a representative TD that integrates various high-quality media and advertising resources.
• Data Supplier & Data Management: Data provision and management platforms support advertisers in more accurately targeting their audience.
• Programmatic TV: Programmatic television advertising provides opportunities for the programmatic purchase of television and outdoor advertising.
• Measurement & Analytics: Monitoring and analytical tools help advertisers evaluate the effectiveness of their advertising.
• pDOOH: Programmatic outdoor advertising, which leverages technology to automate the placement of outdoor advertising. For example, Asiaray (Ya Shi Wei) and DiDi are newly included platforms.

Differences and Similarities between China’s and Foreign Programmatic Advertising Ecosystems

Compared to foreign ecosystems, China’s programmatic advertising ecosystem also faces challenges in data privacy protection and user choice rights. With the implementation of “privacy protection” mechanisms, the space freely available for the audience identification mechanisms that programmatic advertising relies on to operate is increasingly narrowing. There are some significant differences between China’s programmatic advertising ecosystem and that of foreign countries, as follows:

• Market Size and Maturity: Although China’s programmatic advertising market is large, it is still in a stage of continuous development and adjustment compared to the more mature markets of Europe and the United States.
• Technology and Platform Development: China’s programmatic advertising technology ecosystem map shows that the market is adapting to changes in privacy protection mechanisms and audience identification mechanisms, such as OAID replacing IMEI, and IDFA facing more refined authorization for use.
• Influence of Super Platforms: In China’s programmatic advertising ecosystem, large technology companies like HUAWEI Ads occupy an important position through their closed-loop ecosystem products, which is different from the situation abroad where giants like Facebook and Google dominate and work with many small and medium-sized platforms.
• Advertising Forms and Innovation: China’s programmatic advertising is exploring new forms such as Programmatic TV and pDOOH, while the development of these fields in foreign markets may be more mature.

Considerations for Foreign Advertisers Entering the Chinese Advertising Market

• Understand the Market Environment: China’s advertising market has a unique cultural and regulatory environment. Foreign advertisers need to deeply understand these characteristics. An in-depth understanding of Chinese market characteristics and consumer behavior is key to success. For example, Chinese consumers’ dependence on mobile devices is much higher than in other countries, which has an important impact on advertising delivery strategies.
• Data Compliance: With the strengthening of data privacy protection, advertisers must ensure that their data collection and use comply with Chinese laws and regulations. Strictly comply with Chinese laws and regulations, especially in terms of data protection and privacy. For example, understand and comply with the relevant requirements of the “Cybersecurity Law” and the “Personal Information Protection Law.”
• Choice of Partners: Choosing experienced and resourceful local partners can help foreign advertisers adapt to the market environment more quickly and achieve effective market penetration.
• Technical Adaptability: Utilize local Chinese technology platforms and services, such as DSPs and Ad Exchanges, to achieve more precise advertising delivery.
• Cultural Sensitivity and Localization Strategy: Advertising content needs to consider the sensitivity of Chinese culture to avoid cultural conflicts or misunderstandings. Develop advertising content and marketing strategies that conform to Chinese cultural and social values. For example, respecting Chinese traditional festivals and customs can improve the acceptance and effectiveness of advertising.

The development of China’s programmatic advertising has been diverse and dynamically changing, from initial exploration to current refined operations, with the market continuously maturing and improving. The Chinese programmatic advertising market offers great opportunities for foreign advertisers but also comes with challenges. By deeply understanding the market environment, complying with laws and regulations, formulating localization strategies, and choosing the right partners and technology platforms, foreign advertisers can succeed in this vibrant market.

China’s programmatic advertising market has seen unprecedented prosperity since 2012, a year that is also dubbed as the “Year One” of programmatic advertising in China. With the flourishing development of the internet traffic market, China’s programmatic advertising ecosystem has become increasingly mature, gradually meeting advertisers’ needs for fine-group screening of quality customers, comprehensive control and constant adjustment of the advertising process, following customer trends to lock media platforms, and recalling high-potential customers for repeated exposure. This article will provide a complete practical guide based on China’s programmatic advertising market.

01 Planning Phase

Step 1: Define Objectives

Before clarifying the objectives, brands often complete the analysis of the consumer portrait for the promoted product, competitive advertising analysis, and summary of product selling points. With the support of the above information, the brand needs to define the goals of programmatic advertising, whether it is to enhance brand exposure, improve customer awareness, or enhance purchase conversion.

Domestic traffic vendors and media types are diverse and numerous, with a vast array of conversion models and indicators. Advertisers and their agencies need to set targets that are specifically tailored to their advertising needs and platform indicators. Taking the AIPL model indicators of Alibaba, a top-tier e-commerce platform in China, as an example:

Aware: Within the last 15 days, passively interacted with the brand, including behaviors such as exposure & clicks, browsing (limited to one day), watching, etc.

Interest: Within the last 15 days, actively engaged with the brand, including behaviors like membership, followership, interactions, browsing, favorites/add to cart, claiming trial products/samples, etc.

Purchase: All consumers who have purchased brand products in the last two and a half years (2*365 days + 180 days), including those who made pre-sale deposits, scanned codes for Taobao eggs after purchase, used offline cloud POS payment consumers, made purchases via iStore mini-program, scanned codes for Taobao eggs after purchase, included consumers who purchased on Taoxian, including those who bought Tmall u-first samples) minus “Loyalty” consumers.

Loyalty: Consumers who have had positive comments/positive follow-up reviews or have purchased the brand’s products at least twice within the past 365 days.

Step 2: Refine Audience Strategies

Audience strategies are often rooted in product features, brand tone, and combined with past advertising experiences. It is even possible to seek recommendations from local media, third-party advertising agencies, and traffic platforms. The premise of programmatic advertising effectiveness is the brand’s reasonable segmentation of user groups, so that in the process of traffic purchase and expansion, it can better hit the brand’s target audience. Specific classification methods can refer to the “4W1H” model.

Who: Refers to user attributes, judging what type of user it is based on attributes (gender, age, region, income, interests, etc.), such as student groups who love affordable makeup, white-collar workers who like to watch fashion bloggers’ videos, users with a high-level VIP status, etc.

When: Refers to the time corresponding to user behavior, from which the user’s visit duration, frequency, interval, etc., can be calculated. For example, first-time visits to the official website, not logged in for 30 days, purchased within 15 days, etc.

Where: Refers to the user’s source, such as entering through an ad click, through a friend’s share, or through a search engine, etc. Users from different sources represent different groups. For example, those who enter through search keywords belong to an active group of users, which is more in line with the advertiser’s needs; while those who enter by clicking on ads may be interested because of the attraction of the ad content, etc.

What: Refers to the user’s behavior, such as what type of ads they have clicked on, what content they have visited, what products they have purchased, etc.

How: Refers to the user’s quality, which can be measured by visit depth, number of behaviors, order amount, etc. For example, a user who has browsed 50 different product pages, a user who has made a total of 20 orders within a year, a user with an order amount of more than 100,000 yuan in 30 days, etc.

Step 3: Develop Media Strategy

In the face of numerous media resources, it is particularly important to formulate an appropriate media strategy before advertising, which depends on the objectives. The principle of formulating a media strategy is “positive, high coverage, and strong exposure,” and to design the media around advertising forms, page environments, media quality, advertising area, screen position, to meet the KPI requirements.

Advertising Forms: The form of advertising to some extent determines the user experience and interaction form. Common forms in programmatic advertising include banner image ads, video ads, native ads, etc.

Page Environment: Refers to the state of the page where the advertisement is placed, including page content, the number of page advertisements, etc. Especially when placing brand advertisements, advertisers usually require that the page content must be positive, in line with the brand image, and must not contain pornographic and vulgar, politically sensitive information, etc.. Moreover, the number of page advertisements should not be too many. An environment full of advertisements on the entire page will cause trouble for users and seriously affect the user experience, causing users to have a negative impression of the page and the advertisements within the page.

Media Quality: When formulating a media strategy, attention should be paid to the quality and quantity of the media. Quality refers to whether the media’s traffic scale and user groups are of high quality and in line with the advertiser’s needs. In addition, it is necessary to consider the category of these media (such as entertainment), channels (such as TV series), historical data of advertising positions (such as click-through rate), etc. Quantity refers to the media traffic being large enough to ensure sufficient user coverage and meet the advertiser’s budget.

Advertising Area: The ratio of advertising size and the proportion of advertising area on the page are also very important. If the advertising size is too small or the proportion of the entire page is too low, it is difficult to be discovered by users; non-standard size ratios will increase the cost of material production.

Screen Position: The screen position where the advertising position is located determines the probability of the advertisement being seen. The first screen is generally better than the non-first screen, and the effect of the last screen advertisement may be the worst. However, for some pages with high-quality content, the exposure probability of the second screen or even the third screen will also be high.

Step 4: Develop Creative Solutions

The first step in creating creativity is to grasp the form of creativity and the way users interact. The form of creativity refers to what file form the material is presented in, such as images, text, graphics and text, Flash, video, forms, or others. At present, video creativity and post creativity (such as information streams) have the best effects, which are related to the characteristics of the advertising space. The price of such advertising spaces is also a bit higher than that of ordinary advertising spaces.

User interaction refers to the specific operations of users on the material, such as clicking to switch dynamic creativity, filling in registration information on the creativity, expanding the material after clicking on the advertisement, and even submitting information by voice.

In the process of advertising, both the created creativity and the landing page need to undergo A/B testing or multi-version testing, using data to determine which version to adopt in the end. The premise of the test is to keep the test environment and the test volume of multiple versions as consistent as possible.

02 Execution Phase

Step 1: Advertising Preparation

The preparatory work before advertising mainly includes uploading qualifications for review, creating creativity for review, and deploying advertising monitoring, etc.

Qualifications are the necessary proof documents for advertisers to carry out advertising activities (such as business licenses, ICP filing screenshots, organization codes, etc.).

In terms of creativity, traffic parties will also have certain requirements for the effectiveness and legality of the content, so the media needs to review the creativity. Common review scopes include size, sound, etc.

In addition, advertisers generally use third-party monitoring during the advertising process, so there is also the deployment work of monitoring codes, etc. Optimization strategies need to add code in the advertiser’s game promotion page or SDK (or S2S docking), so that the DSP platform can adjust strategies according to different user behavior trajectories.

A good job in the early preparation work does not mean that the ads can be directly placed without manual intervention. Advertising activities should also be gradually increased in multiple stages to ensure the final effect. Programmatic advertising in China can be generally divided into four stages: technical docking test, strategy test, strategy optimization, and stable extension, each with a corresponding time period, and should be flexibly adjusted according to the actual situation of the project.

Technical Docking Test Phase: This phase usually lasts for 1 to 3 days, mainly to check whether the work in the preparation phase runs well, such as whether the statistical monitoring code is deployed correctly, whether S2S docking can correctly return data, etc.

Strategy Test Phase: This phase usually takes 3-7 days to verify whether the media strategy formulated in the advertising strategy is reasonable and whether the media effect has reached the expected level. Based on the test data, corresponding grade divisions are made for different AdX/SSP, different media, different advertising spaces, etc., so as to better allocate the budget in the later stage.

Strategy Optimization Phase: This phase usually lasts for about 1 week to 1 month. On the basis of optimization and adjustment in the early test phase, further optimization of the media is carried out, and the crowd strategy and creative strategy formulated in the advertising strategy are continuously optimized. During the strategy optimization phase, the fluctuation of advertising effects is generally large, which is a normal phenomenon. During this phase, various strategy combinations are usually tried, and the effects of different combinations may vary greatly. The goal of this phase is to quickly screen out the optimal combination of “media + audience group + creativity”, so that the advertising effect reaches a stable change and regular fluctuation trend, such as the effect of the weekend is better than working days, the effect of the evening peak period is better than the daytime, etc.

Stable Extension Phase: This phase is usually more than 1 month according to the brand’s needs. After the stable effect is achieved in the strategy optimization phase, the volume of traffic can be increased according to the budget. Especially in the RTB bidding model, the volume and price of traffic will fluctuate due to the different degrees of market competition, hence the operator needs to be able to find problems in time and take actions.

Step 2: Official Launch

After the qualification and material review are passed, the executor needs to add various advertising campaigns according to the planning plan of the advertising proposal and set up corresponding campaign.

Basic Settings

Bid Setting: Set the upper limit of the price that can be borne, generally in the form of CPM, to control the cost within an acceptable range. Some DSP can support bidding according to CPC or CPA (the algorithm replaces manual dynamic control of CPM bidding).

Budget Control: Set the budget according to the media budget plan provided by the advertiser/advertising agent to avoid excessive consumption. The budget is divided into daily budget, weekly budget, monthly budget, and total budget. Some DSP can also control the level of exposure and the number of clicks, corresponding to daily exposure, total exposure, or daily clicks, total clicks, etc. In addition, there are also settings for budget allocation, such as setting differentiated budgets for different regions, different creatives, etc.

Date and Time: Set the date or time period according to the advertising schedule, or there is no limit. Date and time can be set according to the online habits of the target audience. The date or the daily advertising time period will have an impact on the effect, such as weekends, evening peak periods.

Advertising Speed: The Advertising speed is divided into uniform speed and rapid speed. Some advertisers hope that the advertising budget can be as distributed as possible in each time period or every day, and the activity can be set to “uniform speed”.

Frequency Control: Set the total number of times a specific advertisement is seen by the same user within a set time, or the total number of times a certain advertising material is seen within a set time.

Media Settings

Transaction Model: Select the transaction model, including RTB open bidding, PDB direct purchase, etc.

Ad Exchange: Choose the channel for advertising, such as Baidu Bes, Alibaba Tanx, Tencent AdX, etc.

Media Category/Channel: Select the category of media or a specific channel under a single medium, such as financial, entertainment, sports, and other media categories, or TV drama, movie, technology, sports, and other channels under Youku media.

Media URL: Set specific media root domain names (e.g., qq.com), second-level domains (e.g., news.qq.com), or specific URL addresses.

Placement Size: Choose the placement size and arrange corresponding size materials. Generally, popular ad spaces or commonly used high-quality ad spaces are selected.

Ad Position: Choose the specific ad position, such as WeChat Search Super Brand Zone.

Ad Position Type: Choose the type of ad placement, such as banner, information game, OTV, etc.

Ad Viewability: According to the advertiser’s requirements for viewability, the operators can only target media resources with a viewability higher than a certain value, or conversely, they can exclude media resources with a viewability lower than a certain value and not place ads on this part of the media resources.

Page Ad Slot Quantity: Since the number of ad slots on the page will affect the user experience, it may indirectly cause the user to have a negative impression of the page’s ads. Therefore, when placing ads, you can control the number of ad slots on the page, such as only targeting pages with up to 3 ad slots.

Screen Order: Choose the screen order where the ad space is located, such as the first screen, the second screen, etc. Generally, it is necessary to exclude the bottom of the page such as the tail screen and other positions where users generally cannot see this ad space.

Page Content: Choose to place ads based on designated page keywords, video content direction, such as only placing pages containing baby-related keywords, or only placing workplace drama video ads, and brand can also directly specify TV drama names for directional advertising.

Target Audience Settings

Advertisers can collect people who have seen, clicked on, and visited the official website during the advertising process, and retarget them or use them as the seed segment for look-alike extensions. The target audience may include people with needs, potential needs, and even those who have made purchases, as well as those who are using the product/service or the lost audience.

Creative Settings

Creative and landing page settings: Set up the creative and corresponding landing pages for different advertising campaigns. It should be noted that some AdX will require the landing page to support HTTPS.

Display rules: Set the rules for the order in which the creative is displayed to the same person multiple times. The general rules for the order in which users see the creative are loop rotation, sequential display, etc. For example, if you need to display creative A, B, C to the same user, with a frequency limit of 6 times a week, the order in which a user sees the creative can be AABBCC, ABCABC, etc.

Other Settings

Third-party monitoring: Set the exposure monitoring code and click monitoring code of the third-party monitoring platform.

Brand protection: Select the brand safety supplier that the DSP platform has connected and fill in the corresponding information.

Anti-fraud: Set up to filter fraudulent traffic. Some DSP platforms have anti-fraud mechanisms themselves, but some advertisers will also find third-party anti-fraud suppliers for traffic filtering in order to ensure the effectiveness and reduce waste.

03 Review Phase

Based on the actual feedback data during the advertising period, the brand can summarize the experience and guide subsequent campaigns through comparison, attribution, segmentation, and intersection.

Media optimization: Make the optimal media combination according to the media crowd matching degree, media overlap degree, and media saturation degree. Media matching degree refers to the ratio of the advertiser’s target audience that can be covered in the media; Media overlap degree refers to the ratio of the target audience that overlaps between multiple media; Media saturation degree refers to the ratio of the target audience that has been covered in the media to the total target audience of the media.

Creative Optimization: The match between the ad’s creative and its intended message plays a significant role in determining the effectiveness of an ad campaign. Ad matching refers to how well the creative aligns with the ad’s appeal.

Frequency Adjustment: Identify the optimal frequency by analyzing data from groups exposed to different levels of ad impressions, and establish reasonable frequency capping.

Audience Adjustment: Depending on the scale of the target audience and their conversion outcomes, you can correspondingly increase or decrease the targeting of audience segments.

Viewable Exposure Optimization: Optimize based on data from ad viewability, analyzing visibility metrics across various ad placements, regions, times, and browsers (for instance, visibility might be lower in certain areas or browsers due to differences in audience characteristics or internet connectivity issues). Filter out those with low viewability and fine-tune the advertksk g with various campaign settings to form the best combination.
