Microsoft Just Proved A Point About Search Today

The company that owns a major web index just documented, in its own product, that ranking a page and citing a passage are different jobs. Web IQ arriving at Build on June 2, and AI citation data showing up inside Bing Webmaster Tools earlier this year, were not surprises. As I know well, having built the modern version of Webmaster Tools, the reporting was always going to follow the answer once answers were being generated rather than ranked, and a tool that only ever described the blue links was always going to be lonely. The open question was never whether the citation signal would surface. It was what a platform’s own reporting would, and would not, be able to show you once it did.

The Split Stopped Being A Thesis And Became A Navigation Menu

For a couple of years, the claim that human search and AI answering are two different problems has had to be carried on logic alone. It does not have to be carried that way anymore, because an index owner has put it in the product. Bing Webmaster Tools now holds two separate reports. Search Performance is still there, reporting clicks, impressions, click-through rate, and average position the way it always has. Beside it sits AI Performance, which Microsoft launched in public preview in February, extended in March with grounding-query-to-page mapping, and expanded again in June with a Citation Share metric, still in preview, that reports your share of citations for a given grounding query alongside the raw counts. Microsoft framed that second report, in its own words, as separating AI citations from traditional search, and framed this month’s additions as expanding first-party reporting. Two reports, two definitions of doing well, one tool.

Web IQ is the infrastructure that makes the second report mean something. It is a suite of grounding APIs built on the Bing index but re-architected end-to-end to serve agents rather than people, and instead of returning ranked documents, it returns passage-level evidence objects and structured context. Jordi Ribas, who runs Search and AI at Microsoft, put the framing plainly: Bing was built for humans, and the next era of search is for agents, with some estimates Microsoft cites suggesting agents may generate on the order of a thousand times more queries than all human search combined within a few years. Microsoft says Web IQ already powers grounding in both Copilot and ChatGPT, that it is model-agnostic and speaks MCP natively, and that it runs at a 164-millisecond P95 latency it describes as roughly two and a half times faster than the nearest alternative. It scores retrieved passages on a metric it calls GDSAT, grounding satisfaction, across completeness, freshness, and authority. Take the performance figures as the vendor claims they are and verify them against your own use if they ever bear on a decision. The line beneath all of them is the one that matters most, and it comes from the index owner directly: What makes a page rank well for a human is not…
