Today, interest groups can be updated by fetching new values from a server. For all interest groups, the frequency of these updates is rate limited to at most once a day to conserve network traffic and avoid overwhelming servers. However, we've heard from developers that certain ad campaigns need much more timely updates. During Protected Audience auctions, the browser fetches real-time signals from bidders' key-value servers. This proposal allows the response to these fetches to indicate a subset of interest groups they’d like updated more frequently than once a day. Blink component Blink>InterestGroups <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EInterestGroups> TAG review For Protected Audience: https://github.com/w3ctag/design-reviews/issues/723 TAG review status Completed for Protected Audience, resolved unsatisfied. Risks Interoperability and Compatibility Feature represents optional new behavior that shouldn’t break existing usage. Gecko & WebKit: No signal on parent proposal, Protected Audience. Asked in the Mozilla forum here <https://github.com/mozilla/standards-positions/issues/770>, and in the Webkit forum here <https://github.com/WebKit/standards-positions/issues/158> . Edge: Edge has announced plans to support the Ad Selection API <https://github.com/WICG/privacy-preserving-ads/blob/main/README.md> which shares much of its API surface with Protected Audience. Web developers: Feature requested by Microsoft in GitHub issue <https://github.com/WICG/turtledove/issues/729>. I don't see any feedback from Microsoft on this design in the issue (just from Criteo, which seems inconclusive). Have they given feedback elsewhere? The response from Microsoft (ads) is here: https://github.com/WICG/turtledove/issues/729#issuecomment-1822190741 -- it's the opening paragraph that starts with "I do think having a 'please refresh when this auction is over' lever is a clear improvement over the current situation from a functionality perspective". Debuggability Protected Audience trusted bidding signals show up in the DevTools Network pane. Updates show up in the Application -> Storage -> Interest Groups DevTools pane. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? It will be supported on all platforms that support Protected Audience, so all but WebView. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? Yes <https://github.com/web-platform-tests/wpt/blob/f118165cd650448765d2e0efd3d7ee71f1e15e4f/fledge/tentative/trusted-bidding-signals.https.window.js#L973> .
