Microsoft Copilot answers are built almost entirely from Bing's index, so ranking and indexing in Bing, submitting changes via IndexNow, and structuring content for extraction (clear headings, schema, direct answers) determine whether you get cited. Bing's new AI Performance dashboard and February 2026 guidelines now make citation eligibility an explicit, separate goal from ranking.

*By Josh Bernstein | August 14, 2026*

Seer Interactive analyzed hundreds of ChatGPT search citations against the underlying results and found that 87% matched Bing's top organic results, compared to just 56% for Google. That single number reframes the entire Bing optimization conversation. Teams that write off Bing as a rounding error in search share are, without realizing it, also writing off a meaningful share of what ChatGPT cites, because ChatGPT's web search has long leaned on Bing's index and ranking signals rather than Google's.

Microsoft has spent 2026 turning that dependency into a formal discipline. In February, Bing shipped a public preview of an AI Performance dashboard inside Bing Webmaster Tools, then rewrote its webmaster guidelines to name Generative Engine Optimization as an official category with its own eligibility rules, separate from traditional ranking. This guide walks through how Copilot actually retrieves and cites content, what changed in Bing's guidelines, and the concrete technical and editorial steps that earn citations in Copilot and Bing's generative answers, tracked over time the same way Promptive tracks your brand across ChatGPT, Claude, Gemini, and Perplexity.

How Copilot Actually Answers a Query: Retrieve, Generate, Cite

Copilot's answer pipeline follows a retrieve, generate, cite sequence rather than a single ranking pass. When a user asks a question, Copilot converts it into one or more search queries, sends those to Bing's index to pull back a set of candidate pages, and then extracts the passages most relevant to the question from those pages. Microsoft's own documentation describes this as query optimization followed by information retrieval, with grounding checks and semantic similarity cross-checks run against the retrieved content before anything gets composed into an answer.

Only after that retrieval step does Copilot generate prose. The language model composes a synthesized response using the extracted passages as grounding material, then attaches citations back to the source pages. Since Microsoft's Fall 2025 update, those citations render as prominent, clickable references at the bottom of a response, with a "Show all" option that expands a full source panel. That change matters for GEO because it means Copilot citations are no longer buried; a page that gets grounded in an answer is now visibly credited, which is part of why Microsoft built a dashboard to track it.

The practical implication is that ranking in Bing's traditional index is necessary but not sufficient. A page has to first be crawled and indexed by Bingbot, then be retrievable for the specific query variant a user typed, and finally contain a passage clean enough for the model to lift and attribute without hallucinating around it. Miss any one of those three gates and the page never reaches the citation stage, no matter how strong its backlink profile looks in a traditional rank tracker.

Why Bing's Index Is the Backbone of More AI Search Than You Think

Optimizing for Bing pays off beyond Bing's own market share because multiple AI products lean on Bing's index for web retrieval rather than building and maintaining their own. ChatGPT's web search has historically used Bing to source live results, which is why the Seer Interactive citation-overlap finding cited above is more than a curiosity: it is evidence that a page's Bing visibility is doing double duty across two of the largest AI platforms in use today. With ChatGPT reporting 900 million weekly active users as of OpenAI's February 2026 announcement, Bing's index effectively functions as a retrieval layer for a chunk of the world's largest AI chat audience, not just for the smaller group of people who open Bing.com directly.

This is a structurally different relationship than the one GEO practitioners have with Google. Google AI Overviews and AI Mode draw from Google's own index and Gemini's synthesis layer, a separate technical stack with separate crawl behavior, separate ranking signals, and, per Ahrefs' analysis of overlap between AI Overviews and AI Mode citations, a citation set that only partially overlaps even within Google's own products. Treating "AI search optimization" as one undifferentiated task misses this: a page can rank well in Google's index and still be invisible to Bing's crawler, or vice versa, and each gap quietly closes off a different slice of AI-mediated discovery. Our companion piece on how Google AI Mode and Gemini differ from Bing's approach covers the Google side of that split in more depth.

The strategic takeaway is not that Bing suddenly matters more than Google. It is that Bing optimization is no longer optional GEO work you do after Google is covered. It is a parallel workstream with its own crawler, its own submission tools, and, as of this year, its own webmaster guidelines written specifically for AI citation eligibility.

Get Indexed Fast: IndexNow and Bing Webmaster Tools

Before Copilot can cite a page, Bing has to have crawled and indexed it, and the default crawl-and-wait cycle is too slow for content teams shipping updates weekly. IndexNow closes that gap. It is a free, open protocol that lets a site notify participating search engines the moment a URL is added, updated, or deleted, instead of waiting for a crawler to rediscover the change on its own schedule. Microsoft co-developed IndexNow with Yandex, and it is now used by Bing, LinkedIn, Yahoo, eBay, and other participants, with a single ping propagating to every engine on the protocol.

Setup is a one-time technical task:

  1. Generate an IndexNow API key (a random alphanumeric string) through Bing Webmaster Tools or a plugin for your CMS.
  2. Host the key as a plain text file at your domain root so search engines can verify ownership.
  3. Submit changed URLs via a simple API call or your CMS's IndexNow plugin whenever content is published or updated.
  4. Confirm submissions landed by checking the URL Inspection and IndexNow reporting inside Bing Webmaster Tools.

Bing's submission quota allows up to 10,000 URLs per domain per day, which is generous for all but the largest publishers, and quotas reset daily. Pair IndexNow with a verified Bing Webmaster Tools account and a submitted XML sitemap, and freshly published or updated pages can move from "written" to "crawlable by Bingbot" in hours rather than the days or weeks a passive crawl cycle might take. For sites that publish statistics pages, comparison content, or anything with a shelf life, that speed differential is the difference between being cited on a timely query and missing the window entirely. Our guide to making your site crawlable and parseable for AI engines covers the equivalent technical checklist for other AI crawlers.

*Passive crawling leaves fresh content invisible for days; IndexNow pushes the same change into Bing's crawl queue in hours.*

Inside the New AI Performance Dashboard

Microsoft launched AI Performance as a public preview inside Bing Webmaster Tools in February 2026, and it is the first dashboard from a major search engine built specifically to show publishers how their content performs inside AI-generated answers rather than traditional rankings. It reports on citations across Microsoft Copilot, Bing's own AI-generated summaries, and select partner integrations, giving site owners a direct feedback loop that did not exist before this year.

The dashboard surfaces four core metrics:

  • Total citations: how many times your site was cited as a source in AI-generated answers over a selected period.
  • Average cited pages: the average number of unique URLs from your site referenced daily across AI surfaces.
  • Grounding queries: sample query phrases that triggered your content being retrieved and cited, useful for understanding intent match.
  • Page-level citation activity: citation counts broken out by individual URL, so you can see which specific pages Copilot pulls from most.

Search Engine Land flagged an important limitation worth internalizing: the dashboard shows citation frequency, not what happens after the citation, so it will not tell you whether a Copilot citation converted to a click, a session, or a lead. That gap is exactly why brands pair a native platform dashboard like this with independent tracking; Promptive's monitoring exists to answer the "so what happened next" question across every AI engine at once, not just the one Microsoft is willing to show you inside its own tool. If you are building out a broader measurement habit, our monthly AI visibility audit template walks through how to combine platform-native data with independent prompt tracking.

The February 2026 Guidelines Rewrite: GEO Becomes Official

On February 27, 2026, Microsoft rewrote the Bing Webmaster Guidelines to formally separate "grounding results and citations" from traditional search rankings as a distinct eligibility outcome, and it named Generative Engine Optimization as an official category for the first time among major search engines. The guidelines are explicit that GEO does not guarantee a citation any more than SEO guarantees a top ranking, but the rewrite gives publishers, for the first time, direct technical levers for AI eligibility rather than having to reverse-engineer Copilot's behavior from the outside.

The most actionable changes are the new robots meta directive rules specific to AI grounding:

DirectiveEffect on Copilot and Bing AI answers
NOARCHIVEPrevents the page from being used in Copilot responses or grounding results entirely
NOCACHELimits Copilot to the URL, title, and meta description only, no body content for grounding
NOSNIPPET / DATA-NOSNIPPETCan reduce citation quality by restricting which passages are eligible to be quoted
data-snippet attributeGives publishers paragraph-level control over exactly which text Bing is allowed to cite

If a page carries NOARCHIVE today for reasons unrelated to AI (a leftover from an old CMS default, for example), it is silently opting out of Copilot citations without anyone realizing it. That is worth an audit on its own. The guidelines also expanded the definitions of AI abuse: "Keyword Stuffing" now explicitly covers "Artificially Engineered Language," content structured to game AI extraction rather than serve readers, and a new "Prompt Injection and AI Manipulation" section addresses attempts to plant hidden instructions aimed at language models. On the content-quality side, the language softened from treating all machine-generated content as suspect to focusing specifically on large-scale content published "without oversight, quality control, or editorial review." Scaled, unedited AI content is the target; well-edited content that happens to involve AI assistance is not.

Schema and On-Page Signals That Help Copilot Extract and Cite You

Copilot's citation stage depends on extracting a clean, self-contained passage from your page, which means the same structural clarity that helps a human skim a page also helps a model quote it accurately. Clear H2 and H3 headings that state the actual sub-question being answered, short paragraphs that lead with the conclusion, comparison tables for anything involving options or tradeoffs, and a direct summary near the top of the page all reduce the model's work in finding a citable chunk.

Schema markup still earns its place in this stack, even though its role has shifted. Google removed the visual rich-result treatment for FAQPage on May 7, 2026, following the earlier removal of HowTo rich results in 2023, so neither schema type produces a special SERP snippet in Google anymore. But both remain valid schema.org types, and structured FAQPage and HowTo markup still gives AI engines, including Copilot, a machine-readable map of question-and-answer or step-by-step content that is easier to extract cleanly than the same information buried in unstructured prose. Pair that with Article or BlogPosting schema carrying accurate author, publish date, and organization fields, since Copilot's grounding checks weigh provenance signals like these when deciding whether a source is trustworthy enough to cite. Our deep dive on using schema markup to win AI citations covers the full implementation checklist, and the anatomy of what actually gets quoted is worth studying directly if you want to reverse-engineer the format.

Content that earns the citation, not just the crawl

Being crawlable gets you into the candidate pool; being genuinely citable is what wins the slot. The KDD 2024 GEO study from Princeton and Georgia Tech researchers, tested on a benchmark designed to mimic Bing Chat's retrieval behavior, found that adding statistics to a page improved its visibility in generative answers by 41%, adding direct quotations improved it by 28%, and citing authoritative external sources improved visibility by as much as 115% for pages that started ranked around position five. Pages already sitting at position one benefited the least from these tactics, since they were already the default pick. The lesson for Bing and Copilot specifically: if you are not the number one organic result for a query, structural and evidentiary improvements to the page itself can close more of the gap than another round of backlink outreach.

Copilot vs. Google AI Overviews: Where the Playbooks Diverge

Treating Copilot optimization as "the same thing as Google AI Overviews, but smaller" is the most common mistake teams make, and it costs them citations they could otherwise win. The two systems pull from separate indexes, weight different signal types, and even cite different pages when asked the same question. Ahrefs' analysis of overlap between Google's AI Overviews and AI Mode found citation agreement well under half even within Google's own two products, which is a useful reminder that "optimize for AI search" is never really one task.

DimensionMicrosoft Copilot / Bing generative answersGoogle AI Overviews / AI Mode
Underlying indexBing's web index, also used by ChatGPT searchGoogle's own index, synthesized via Gemini
Primary discovery toolBing Webmaster Tools, IndexNow, BingbotGoogle Search Console, standard crawl
Citation transparency toolAI Performance dashboard (public preview, Feb 2026)No equivalent native citation dashboard

Click-through impactGrowing, follows Bing's smaller overall query volumeAI Overviews correlate with a 58% CTR drop for the #1 result (Ahrefs, Dec 2025)

The practical consequence is that a page optimized purely for Google's AI Overviews, tight snippet-length answers tuned to Google's extraction patterns, will not automatically perform the same way in Copilot. Copilot's Fall 2025 update pushed toward more comprehensive, source-rich answers with a dedicated "Search" mode for deeper queries, which rewards content that goes further than a single-sentence answer and builds out supporting context, data, and named sources. Teams running a genuine cross-engine program need separate technical checklists for Google and Bing even when the editorial content underneath is shared, a distinction our GEO vs. SEO vs. AEO breakdown explores from the budget and workflow side.

A Practical Copilot and Bing Optimization Checklist

Turning the sections above into a working program does not require a large team, but it does require sequencing the technical prerequisites before the editorial work, since Copilot cannot cite what Bing has not indexed.

  1. Verify your site in Bing Webmaster Tools and confirm Bingbot is not blocked in robots.txt, a step teams sometimes miss because they only ever checked Google Search Console.
  2. Set up IndexNow so new and updated pages reach Bing's crawl queue in hours instead of waiting on the passive crawl cycle.
  3. Audit robots meta tags site-wide for stray NOARCHIVE or NOCACHE directives that silently block Copilot grounding.
  4. Add or refresh FAQPage, HowTo, and Article schema on pages where it is topically accurate, treating it as an extraction aid rather than a shot at a rich result.
  5. Restructure top pages around answer-first paragraphs, direct statistics, named sources, and comparison tables that give the model a clean passage to lift.
  6. Check the AI Performance dashboard monthly to see which pages are already being cited and which grounding queries are triggering them.
  7. Track citations independently across Copilot, ChatGPT, Gemini, Claude, and Perplexity rather than relying solely on Bing's own self-reported dashboard, since it will not show you competitor activity or cross-engine trends.

Steps one through four are one-time technical fixes. Steps five through seven are the recurring cadence, and they are the same cadence that works for earning citations from ChatGPT given how much retrieval infrastructure the two platforms share.

Frequently Asked Questions

Does Microsoft Copilot use the same index as Bing search?

Yes. Copilot's web retrieval runs through Bing's index rather than a separate crawl system, which is why Bing Webmaster Tools, IndexNow, and Bing-specific indexing signals directly affect whether Copilot can find and cite a page. A page invisible to Bingbot is invisible to Copilot's grounding step as well.

Does optimizing for Bing also help with ChatGPT citations?

It can, since ChatGPT's search functionality has relied on Bing's index and ranking signals for web retrieval. Seer Interactive found 87% of ChatGPT search citations matched Bing's top organic results, compared to 56% for Google, so Bing indexing work carries value beyond Bing's own traffic.

What does the Bing AI Performance dashboard actually show?

It reports total citations, average cited pages, sample grounding queries, and page-level citation activity across Microsoft Copilot, Bing's AI summaries, and select partner integrations. It does not report clicks, conversions, or downstream business outcomes tied to those citations, which is a known limitation Search Engine Land flagged at launch.

Do FAQPage and HowTo schema still matter if Google removed their rich results?

Yes, for a different reason than before. Google phased out the HowTo rich result in 2023 and removed the FAQ rich result from search on May 7, 2026, so neither produces a special visual SERP snippet in Google anymore. Both remain valid schema.org types that help AI engines, including Copilot, parse and extract question-and-answer or step-by-step content more cleanly.

What should I do about NOARCHIVE and NOCACHE tags on my site?

Audit them immediately. Bing's February 2026 guidelines rewrite confirmed that NOARCHIVE blocks a page from Copilot citations entirely, and NOCACHE restricts Copilot to the URL, title, and meta description with no body content for grounding. Legacy CMS defaults sometimes apply these tags without anyone noticing.

How is Copilot different from Google's AI Overviews for GEO purposes?

They pull from separate indexes (Bing's versus Google's), use different citation-eligibility rules, and even cite different pages for identical queries, with Ahrefs finding limited citation overlap between Google's own AI Overviews and AI Mode. A program built only around Google's snippet patterns will not automatically transfer to Copilot's more source-rich, chat-first answer format.

How often should I check Bing's AI Performance dashboard?

A monthly cadence lines up well with typical content publishing and refresh cycles, giving enough time for IndexNow submissions and schema updates to show measurable movement in citation counts and grounding queries between checks.

Is Bing worth the effort given its smaller market share compared to Google?

Its direct market share is modest, but its index function extends well past Bing.com itself, since ChatGPT search draws heavily on the same index and ranking signals. Optimizing for Bing is closer to optimizing a shared retrieval layer than optimizing a single, self-contained search engine.
