Bing SEO: What Ranks There, and Where It Differs From Google

By Muntazir · Published 31 October 2026

In July 2020, Bing published a numbered answer to a question most search engines leave to speculation: what decides a ranking. Six factors, named and ordered — relevance, quality and credibility, user engagement, freshness, location, page load time — sitting in Bing’s own webmaster guidelines, free for anyone to read.

What does Bing say actually decides a ranking?

Microsoft’s rewritten guidelines, covered by Search Engine Roundtable on 1 July 2020, list the six in roughly this order: how well a page matches what the query is actually asking, the credibility of the page and its author, how searchers behave once they click through, how current the information is, where the page and the searcher both sit geographically, and how fast the page loads. Bing’s own wording calls this list “general order of importance” and adds that the weight shifts “from search to search” — an admission, in writing, that no fixed formula sits behind it.

That qualifier matters more than the list itself. A named factor with an unstated, shifting weight is not a formula a site can reverse-engineer. It’s closer to a statement of values than a blueprint.

Why would a search engine put that in writing at all?

Google has never done the equivalent. Not a numbered list, not an order of importance — its public position on ranking factors comes out piecemeal, one denial at a time, usually from an engineer answering a single question rather than from a published inventory. Search Engine Journal’s own review of domain age as a ranking factor makes the pattern visible: the conclusion rests on a scattered record of individual statements, not a document anyone can point to and read start to finish.

Publishing a named, ordered list is a choice, and a smaller search engine has more reason to make it. Being legible about what it rewards is also a pitch for using it.

Does Bing really reward things Google denies?

The most repeated version of that pitch is domain age: Bing is supposed to favor an older, established domain in a way Google doesn’t. It’s a durable claim across SEO guides, and it turns out to rest on uneven evidence. Domain age is not one of Bing’s own six named factors. No Microsoft document says it is. The claim traces to a mix of forum testimony and vendor guides, not to the guidelines Bing itself published.

Google’s half of the same comparison is sourced far better. Asked directly on social media whether domain age affects ranking, Google’s John Mueller answered with a single word — “no” — back in April 2017, and has repeated versions of that answer since. So the popular framing (“Bing cares about old domains, Google doesn’t”) turns out to be stronger on the Google side, which denies it on the record, than on the Bing side, which has never actually claimed it.

A tool built to check a site’s AI visibility runs into this asymmetry directly, without resolving it. One of its checks flags a domain younger than six months with a note that new domains carry little trust with search engines generally, and rarely show up yet in the material language models were trained on. The finding doesn’t name an engine. It’s written as a general caution — the same note whether the business is chasing Bing, Google, or neither one specifically — because the product has no way to say which engine, if either, actually penalizes youth and by how much. That’s not a gap unique to this one check; it’s the same gap the rest of this article keeps running into.

Does any of this reach Copilot or ChatGPT?

For Copilot, directly: its web answers are built from the same index Bing search ranks pages in, a connection covered in more detail in the piece on Bing Places. A page Bing ranks poorly is a page Copilot is less likely to ground an answer in, by the same mechanism, before any question of listings or profiles enters into it.

For ChatGPT, the link has weakened rather than strengthened, which is the opposite of what most of the SEO advice from 2023 still assumes. The piece on IndexNow covers why: after leaning on Bing’s results for its first two years, OpenAI built its own crawler and search index, and neither company publishes a figure for how much weight Bing still carries in a given answer today.

Everything above assumes Bingbot reached the page at all. A free check of what a site’s robots.txt actually allows answers that narrower, more mechanical question first — none of the six ranking factors matter to a page Bing never crawled. A broader look at AI crawler access covers the rest of that foundation.

Did the six factors survive the 2026 rewrite?

Bing’s guidelines were rewritten again in February 2026, mainly to extend their scope to Copilot and its grounding results and to fold in a new definition of AI-specific abuse. That rewrite also dropped a section that used to cover social-media-scheme abuse specifically — one more sign that what counts as gaming Bing’s rankings keeps shifting even where the six named factors themselves haven’t been reissued with new wording. As far as the public record shows, the 2020 list is still the one in force: unrevised, as stated, for six years, even while the guidelines around it keep getting rewritten.

That’s the harder asymmetry to sit with. A list six years old is either stable enough not to need revising, or just old enough that revising it would mean admitting how much has quietly changed since — and a search engine that already told readers its own weighting “varies from search to search” has left itself room to claim either. What’s confirmed, six years on, is narrower than most of the advice written about it: a smaller engine named six things and an order. Its larger rival has never had to, and the absence is the more interesting fact of the two.
