Header bidding implementation
Did you know that publishers who implement header bidding can increase their ad revenue by up to 50%? SEMrush 2023 Study shows that header bidding has become a crucial strategy for maximizing yield. However, one of the main concerns holding some publishers back is latency. In this section, we’ll explore how to implement header bidding effectively, specifically focusing on Prebid.js integration.
Prebid.js integration
Integrating the Prebid.js library
To start integrating Prebid.js, you first need to include the Prebid.js library in your web page. This library is an open – source header bidding wrapper that enables publishers to monetize their ad inventory through client – side header bidding (source: info [1]). For example, a publisher of a tech blog decided to integrate Prebid.js. By including the library, they were able to allow multiple demand partners to compete simultaneously for ad space, which increased their revenue potential.
Pro Tip: It might be preferable to server – side generate the prebid js, bidder setup, and so forth into one file and minimize it to reduce latency (source: info [2]).
Loading the ad server library file
After integrating the Prebid.js library, the next step is to load the ad server library file. This file is essential for the proper functioning of the ad server within the header bidding system. For instance, if you are using Google Ad Manager as your ad server, you need to load its corresponding library file accurately.
Running the header auction
Once the Prebid.js library and the ad server library file are in place, it’s time to run the header auction. During this process, multiple demand partners bid for your ad space simultaneously, increasing the competition and potentially driving up the prices.
Google Ad Manager
To set up Google Ad Manager for Prebid – Rendered, you need to follow specific trafficking, line item, and creative setups as described in info [3]. This involves configuring the line items correctly, setting up the creative for different formats like banner, in – renderer, and AMP.

Wrapper vs direct setup
When implementing header bidding, you have two main options: a wrapper setup or a direct setup. A wrapper setup, like using Prebid.js, offers more transparency and control. It allows you to manage multiple demand partners easily and control the targeting of your ads. On the other hand, a direct setup may involve working directly with an ad server without the use of a wrapper.
Comparison Table:
| Setup Type | Advantages | Disadvantages |
|---|---|---|
| Wrapper Setup (e.g., Prebid.js) | More transparency and control, easy management of multiple demand partners | |
| Direct Setup | Potentially less complex, may have lower latency in some cases | Less control over demand partners, limited competition |
Key Takeaways:
- Prebid.js integration involves integrating the library, loading the ad server library file, and running the header auction.
- Different ad servers have their own setup requirements when working with Prebid.js.
- Consider the pros and cons of wrapper and direct setups when implementing header bidding.
As recommended by industry experts in ad technology, when implementing Prebid.js, regularly monitor the bid performance using client – side analytics (source: info [4]). Try our ad performance calculator to see how different setups can impact your revenue.
Latency optimization
Did you know that a one-second delay in page load time can lead to a 7% reduction in conversions? In the world of header bidding, latency can be a significant roadblock for publishers. Understanding and optimizing for latency is crucial for a seamless user experience and maximizing revenue.
Common causes of latency in Prebid.js integration
Slow bidder response
Bid latency allows us to view bidders based on how fast or slow they are on average. Bidders with high average bid latency can create bottlenecks for your setup. For example, if you have a bidder that consistently takes a long time to respond, it can slow down the entire bidding process. According to a SEMrush 2023 Study, slow bidder response is one of the top causes of latency in header bidding.
Pro Tip: You can follow the bid latency to see which of your demand partners is slowing down bidding and who brings the worst time-out. Set the timeout to 5000ms, and then reduce it until one header bidder fails. Check the pbjs._bidsReceived array to see the results. If you have just one slow bidder, drop them and set the timeout to about 100ms above the slowest acceptable bidder. Keep in mind that regional differences cause different levels of latency.
Complex script structure
A complex script structure can also contribute to latency. Pre-bid calls are being sent and received before page content even loads, and pre-bid partners may be sending inventory information onto DSPs or other sources to get bids. That’s a lot of variables, which can make for a complex and time-consuming process. For instance, some ad networks create header bidder scripts which append their header bidder to the existing setup, adding to the complexity.
Large file sizes
Large file sizes can slow down the page load time. If the Prebid.js files, bidder setup, etc., are large, it can take longer for the browser to download and execute them. As recommended by Google PageSpeed Insights, it might be preferable to server-side generate the prebid js, bidder setup, and so forth into one file and minimize it to reduce latency.
How Prebid.js reduces latency
The high page latency issue has prompted the evolution of header bidding. As the challenges associated with client-side technology became apparent, the industry moved to server-side header bidding. Server-side header bidding reduces the latency compared to client-side header bidding. For example, client-side header bidding offers more transparency and control, but can also increase the page load time and browser requests.
Pro Tip: When using Prebid.js, monitor bid performance with client-side analytics. This can help you identify which bidders are causing latency and make adjustments accordingly. You can also dynamically determine which bidders to use based on analytics, ensuring that you only work with the fastest and most reliable ones.
Key Takeaways:
- Slow bidder response, complex script structure, and large file sizes are common causes of latency in Prebid.js integration.
- Server-side header bidding can reduce latency compared to client-side header bidding.
- Use client-side analytics to monitor bid performance and make adjustments to optimize latency.

Analytics in header bidding are the cornerstone of optimizing your ad revenue and performance. They offer valuable insights into how your header bidding setup is performing, allowing you to make data – driven decisions.
Analytics solution components
Analytics adapter for Prebid.js
An analytics adapter for Prebid.js serves as the bridge between your Prebid.js implementation and your chosen analytics tools. It captures crucial data about bid requests, wins, and performance metrics. For example, it can track the number of bids each bidder makes, the win rate of different bidders, and the CPM (Cost Per Mille) values. This data is essential for understanding the effectiveness of your header bidding partners. Pro Tip: Regularly update your analytics adapter to ensure it can capture the latest data points and work seamlessly with your Prebid.js version.
Analytics data pipeline
The analytics data pipeline is responsible for collecting, processing, and storing the data from your Prebid.js implementation. It takes the raw data captured by the analytics adapter and transforms it into meaningful reports. A well – structured data pipeline can handle large volumes of data efficiently. For instance, some publishers use cloud – based data storage solutions like Amazon S3 to store their analytics data. As recommended by Google Cloud Platform, it offers scalability and reliability for handling header bidding analytics data.
Support for multiple analytics providers
Prebid.js allows you to integrate with multiple analytics providers simultaneously. This gives you the flexibility to compare and contrast data from different sources. For example, you could use Google Analytics for general website traffic and performance data, and a specialized header bidding analytics tool like PubMatic OpenWrap for more in – depth ad – specific metrics. By having support for multiple providers, you can get a more comprehensive view of your header bidding performance.
Integration process
Creating an account and obtaining IDs
To integrate an analytics provider with your Prebid.js setup, the first step is to create an account with the analytics provider. Once you have an account, you’ll need to obtain specific IDs, such as API keys or tracking codes. These IDs are used to establish a connection between your Prebid.js implementation and the analytics provider. For example, if you’re using a tool like Snowplow Analytics, you’ll need to generate a tracking code in your Snowplow account and then add it to your Prebid.js code.
- Sign up for an account with your chosen analytics provider.
- Navigate to the settings or API section of your account to find the ID generation option.
- Generate the necessary IDs and add them to your Prebid.js configuration file.
Insights for decision – making
The analytics data collected provides valuable insights that can guide your decision – making. For example, if you notice that a particular bidder has a low win rate but high CPM, you might want to adjust your bidder settings to give that bidder more opportunities. Or, if you see that certain ad formats are performing better than others, you can focus your inventory on those formats. This data – driven approach helps you optimize your header bidding setup for maximum revenue.
Impact on default functionality
Adding analytics to your Prebid.js setup generally has minimal impact on the default functionality. However, it’s important to test your setup thoroughly after integration. In some cases, there may be a slight increase in latency due to the additional data collection and processing. It might be preferable to server – side generate the prebid js, bidder setup, and so forth into one file and minimize it to reduce latency (as mentioned earlier). Test results may vary, so continuous monitoring is crucial.
Role in setup and performance monitoring
Analytics play a vital role in both the initial setup and ongoing performance monitoring of your Prebid.js implementation. During setup, analytics can help you identify any issues with bidder connections or data collection. Once your setup is live, continuous monitoring of analytics data allows you to spot trends, detect anomalies, and make timely adjustments. For example, if you notice a sudden drop in fill rate, you can use the analytics data to identify the root cause, such as a problem with a particular bidder or ad unit.
