What a Bing Result Page Is Actually Built From
Bing is Microsoft's search engine, and bing.com is the front door to it. The same crawl and index sit under Copilot: Microsoft's webmaster guidelines describe a single crawling, indexing and ranking foundation behind Bing search, Copilot and grounding results, and treat eligibility for citations in AI answers as an extension of ordinary indexing. That makes a Bing position worth more than the engine's search share alone suggests.
The result page has a stable skeleton. Organic results sit in an ordered list of b_algo items, ten to a page. Each carries a linked heading with the matched terms in bold, a display domain, a breadcrumb citation line, a two line snippet, a site favicon and, where Bing holds a date, a date stamp printed inside the snippet. Above the list sits the count line, written as About N results, and the scope bar for the verticals Bing serves separately: web, images, video, shop, news, local, flights, menu and Copilot search. A time filter offers all, past 24 hours, past week, past month, past year, or a custom start and end date.
Two details decide whether a Bing scraper produces clean rows. Every organic and paid link is wrapped in a bing.com/ck/a redirect, and the real destination is base64 in the u parameter behind an a1 prefix, so the target has to be decoded rather than read off the page. Bing also bolts its own msockid tracking parameter onto many destinations, and leaving it in place splits one URL into several rows. Paging runs on first=11, first=21 and so on, ten results a step, next to a per session token that the pagination links carry.
