Bing Web Search API best practices

Google is answering this query itself, and 2 of the 4 sources it credits do not appear in the ten results below.

A domain marked Cited, not ranking is credited in Google's answer while sitting outside the ten organic results. Across the whole corpus that is true of 38.8% of citations.

A dot means the domain was not on page one that week. This is the part no live SERP checker can show you: it needs someone to have been measuring before you asked.

Overlap is the share of domains the two result sets have in common. Most rank tracking quietly assumes one country; this is what that assumption costs.

Filled means Google rendered the block for this query this week. AI Overview, People Also Ask, Related searches, Knowledge panel, Sitelinks — each has its own prevalence across all 4,185 queries.

Every figure above comes from one call. This is that call — the same endpoint, the same parameters, run once a week.
