Get cited by Copilot.

Bing + frontier models, everywhere.

Copilot's stack has more surfaces than any other AI assistant — and they all share a retrieval backbone, even when the generation model varies.

Bing index (retrieval). Microsoft's web index is the retrieval substrate for every Copilot surface that grounds in the open web. Ranking on Bing is the eligibility gate for citation — full stop, no exceptions, the same fact across consumer and enterprise Copilot.

Generation models. Copilot routes generation through a mix of OpenAI's GPT models and Microsoft's own MAI (Microsoft AI) models, depending on surface, tier, and task. The generation choice doesn't change which sources get cited — that's the retrieval/rerank layer — but it does affect synthesis style.

Prometheus. Microsoft's retrieval-augmented pipeline that decides what to fetch, how to chunk it, and how to ground answers. Pages cited by Copilot are pages Prometheus reranked into the top of its candidate pool. The reranker biases for clarity, structure, freshness, and trusted-source provenance.

Microsoft 365 surfaces. Copilot in Word, Excel, PowerPoint, Outlook, and Teams. These surfaces draw on the user's own data plus Bing-grounded web retrieval when the query requires external context. 15 million paid seats route through these every workday.

Edge / Windows / Bing.com. Consumer Copilot surfaces. Edge sidebar, Windows taskbar, Bing.com chat — all sharing the same underlying retrieval and (mostly) the same model layer. 140 million daily Bing users are exposed to Copilot answers across these surfaces.

Why Copilot GEO starts with Bing SEO.

Copilot is the only major AI assistant whose retrieval layer is a single, well-documented public search index. ChatGPT runs on a hybrid (its own index plus Bing). Claude runs on Brave. Perplexity runs on its own crawler. Gemini runs on Google. Copilot runs on Bing — and only on Bing. Every Copilot citation, across every surface, comes from a page that ranks (or could rank) on Bing.

This makes Copilot GEO unusually concrete. We can run a query on Bing today, see which pages rank, and predict — with high accuracy — which will be cited by Copilot tomorrow. The signal is observable, the optimization is measurable, and the work compounds the work we do for the Bing SEO program one-to-one.

The implication for clients running both programs: Copilot adds about 20% to the work and probably 5x to the visibility. The structural-extractability layer and the AI-bot accessibility layer are the only meaningful additions. Everything else is Bing.

The implication for clients running Copilot alone: there's no shortcut. Bing visibility is the prerequisite. We always ship the underlying Bing optimization first, then layer the GEO-specific extractability and bot-access work on top.

Bingbot, IndexNow, and AI-bot access.

Copilot's technical stack is mostly Bing's technical stack — with one important AI-bot wrinkle. We audit it on every engagement.

Bingbot. Same crawler that drives Bing's organic index, same crawl-budget rules, same JS-rendering limits. Bing's relative weakness on JavaScript-heavy pages applies to Copilot in full — SSR or SSG remains the safest delivery model.

IndexNow. Microsoft's URL-push protocol is the fastest way to get new content into Bing's index, which is the fastest way to get it cited by Copilot. We deploy IndexNow on every Copilot engagement; it's free, well-documented, and consistently underused.

OAI-SearchBot accessibility. Some Copilot surfaces route through OpenAI's search backbone alongside Bing. Allowing OAI-SearchBot in robots.txt closes a small but meaningful retrieval gap.

Schema. JSON-LD is the highest-leverage non-Bing-rank signal for Copilot citation. Article, FAQPage, Product, Organization, BreadcrumbList — all foundational. Q&A and HowTo schema where appropriate provide additional Prometheus-rerank weight.

llms.txt. Microsoft hasn't formally adopted llms.txt for Copilot, but its presence has neutral-to-positive effect across the broader AI ecosystem and we deploy it as a baseline. Cost is low; downstream upside compounds.

Bing Webmaster Tools. The diagnostic surface for Copilot eligibility. Crawl errors, query data, and Clarity-derived UX signals are all visible here — we treat Webmaster Tools as a primary instrument, not a secondary one.
