Google Discover bug exposes internal discover.aigc domain powering AI Summary cards
AndellDam · x · 2026-11-05
SEO practitioners spotted Google Discover cards leaking an internal domain, discover.aigc, in their source code. It's not a public URL but a label for the raw request the Discover feed sends to Google servers to fetch AI Summary text — instead of rendering as "AI Summary", a mirror-rendering bug exposes the raw code in the feed.
- AndellDam shared concrete examples: each AI summary cluster has an AIGC ID (e.g. 5773692770529002137) and a Photon Card ID, addressable via discover.aigc/?id=...
- The domain only resolves between Google's internal servers and won't load externally
