If everything works as expected, it's time to scale this implementation. Deploy the same code to more target websites. This will enable you to observe more users, collect more topics data, and deepen your understanding of your audiences.</p> <p>Here's a step-by-step summary of how you can scale to production:</p> <ol> <li>Test your topics-based solution on a higher volume of traffic. <ul> <li>Add your iframe to more sites you own with a larger number of visits and follow the <a href="https://developers-google-com.translate.goog/privacy-sandbox/private-advertising/topics/web/test-and-go-live?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=auto#load-testing">instructions below</a> to perform load testing.</li> </ul></li> <li>Deploy your solution to publishers' sites. <ul> <li>Once your solution is working correctly in your own testing environment, collaborate with publishers to integrate your iframe into their websites. For example, they may need to update the library that includes your iframe.</li> </ul></li> <li>Process and use topics data (estimated time: around four weeks). <ul> <li>Incorporate topics data as an additive signal alongside other data.</li> <li>Source real-time-bidding testing partners.</li> <li>Run utility testing with topics as an additive signal to your other data.</li> </ul></li> </ol> <h3 id="load-testing" data-text="Load testing" tabindex="-1">Load testing</h3> <p>To ensure your system can handle the traffic, we recommend performing load testing before deploying your topics-based solution to publishers' sites.</p> <ol> <li>Deploy gradually across more <a href="https://developers-google-com.translate.goog/privacy-sandbox/private-advertising/topics/web/test-and-go-live?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=auto#target-sites">target sites</a> that you own, especially those that have a larger volume of traffic.</li> <li>Perform load testing for your topics data, according to your expected traffic. <ul> <li>You will need to send topic information from the iframe to your <a href="https://developers-google-com.translate.goog/privacy-sandbox/private-advertising/topics/web/test-and-go-live?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=auto#backend">backend</a>. This lets you further process the Topics API results and use them as an additional signal to help select ads that are more relevant to the user. As more sites incorporate your embed, the number of calls to your backend will increase significantly. Confirm that your backend can handle a large volume of calls from the iframe.</li> <li>Set up metric collection and logs for analysis.</li> </ul></li> <li>Immediately after deploying the Topics API, check your metrics to detect any severe end-user issues.
