Bing Indexing via IndexNow
IndexNow is an open protocol for notifying participating search engines about added, updated or deleted URLs. The request contains the URL and a domain-controlled key. Each search engine decides whether and when to fetch or index the URL.
How IndexNow actually works under the hood
You place a plain-text key file at an allowed location on your server. FastIndexing can then send the IndexNow request to a supported endpoint and record its response. Coverage depends on the selected endpoint and participating engines; FastIndexing does not claim simultaneous processing by every engine.
An important framing note: IndexNow is a notification, not an indexing guarantee. Bing still applies its own crawl and quality decisions. Thin content, duplicate pages or technically broken URLs do not get a pass because they were signaled.
Why Bing Matters for AI Search (Copilot)
Microsoft Copilot — in the browser, in Windows, in Teams and Office 365 — pulls live web content directly from the Bing index. If your pages are not indexed in Bing, Copilot cannot cite them. That is not speculation; it is the documented architecture: Copilot with web grounding uses Bing as its underlying data source.
This changes the prioritization math for a lot of sites. Even if your audience is primarily a Google audience by habit, any research that runs through Microsoft tooling — Edge, the Windows search bar, Copilot in Word or Excel — routes through Bing. B2B companies operating in Microsoft-365 environments should pay particular attention: a vendor that does not appear in Copilot is invisible at the AI-assisted stage of the buying process.
### Bing indexing as an AI visibility signal
AI search layers weight recency alongside relevance. When Bing receives an IndexNow signal the moment you publish, Copilot can draw on that content in real time rather than waiting for the next passive crawl cycle to surface it. For news publishers, event pages, e-commerce product listings, or any content with a short shelf life, that timing difference is concrete. A crawl that happens three weeks late returns information that is already stale.
For a full breakdown of how to get indexed on Google — different channels, different rules — see Google indexing.
IndexNow Without Search Console
Google Search Console is the default tool most practitioners reach for, but it has real constraints: it requires verified domain ownership, it is scoped entirely to Google, and setup involves DNS records or HTML tags. IndexNow does not share any of those requirements. There is no GSC needed, no ownership confirmation, no Google-specific handshake.
That makes IndexNow particularly useful in agency work. You can submit URLs for client domains without needing GSC access. Staging environments, newly launched domains, bulk CMS deployments, sites without a dedicated technical contact — all of these work fine. As long as the key file is on the server, FastIndexing can start signaling Bing right away.
When IndexNow alone is enough
If your primary goal is Bing visibility — US market, older demographic skewing toward Windows defaults, B2B with Microsoft infrastructure — IndexNow is the most direct path available. No approval queue, no intermediary layer. You supply URLs, the protocol handles the communication.
For Google, you need different channels: GSC sitemaps, internal linking and backlink discovery signals, or the GSC Indexing API for eligible content types. We cover all of those on /google-indexing. The channels are not mutually exclusive; FastIndexing processes both.
Bing Webmaster Tools vs. FastIndexing
Bing Webmaster Tools (BWT) is Microsoft's free console — the official toolset for crawl statistics, keyword data, sitemap submission, and manual URL submission. For a small site or a one-off submission of a few pages, BWT is a reasonable starting point and costs nothing.
The ceiling shows up fast. Manual BWT submission has a daily limit, it is designed for individual entries, and there is no automation layer. An agency managing dozens of client domains, or a publisher pushing hundreds of new URLs per day, will hit that ceiling fast.
What FastIndexing adds
FastIndexing fires IndexNow signals programmatically, in bulk, with a log of every URL submitted and the timestamp it was sent. You can track signaled URLs in the dashboard and verify actual indexing rates through the index checker. Whether and when Bing crawls and indexes a given URL remains Bing's decision — FastIndexing optimizes the signal, not Bing's internal quality assessment.
For agencies with multiple client domains, owner-scoped projects and guided tasks of up to 500 URLs keep reviewed work organized. This release does not provide publish-time automation or a public Agency API.
The Limit: Bing Is Not Google
Honesty first. Bing holds a small share of the global search market — under 10% in most European countries, somewhat higher in the US, meaningfully higher in B2B Microsoft-heavy environments. If you operate exclusively in a Google-dominant, consumer-facing market, Bing indexing will not move your traffic needle as a primary lever.
More important to say clearly: IndexNow does not index in Google. Google has not joined the IndexNow protocol and has made no public commitment to do so. The theory that IndexNow indirectly signals Google — through crawl activity, or correlated backlink behavior — is unconfirmed. We do not repeat it. If your goal is Google indexing, you need Google's own channels. We cover those on /google-indexing.
When Bing indexing is worth the effort
Bing makes sense when: (a) your audience disproportionately uses Microsoft products — B2B, US market, enterprise environments; (b) you publish content that feeds Copilot responses — product specs, pricing, availability, news; (c) you are already using IndexNow and Yandex reach comes as a side benefit; or (d) you are an agency that documents indexing efforts per channel and Bing is a deliverable line item for clients.
FastIndexing checks technical readiness, sends only discovery signals applicable to the URL and search engine, and monitors status from D0 through D14. The search engine alone decides whether and when the URL is indexed. We do not promise an aggregate or Bing-only indexing rate, and no individual URL is guaranteed.
From the field
Dmytro Puhach, Founder · 15+ years in SEO
I have been running IndexNow signals since the protocol launched. Not because Bing replaces Google — it does not — but because the signal is cheap once you have it wired in, and the Copilot angle is real enough to take seriously.
What I find useful about IndexNow specifically is the lightweight protocol. The domain-controlled key file and request still need to be configured correctly, but no GSC connection is involved.
What I do not promise: that Bing will crawl, index or rank a page after notification. FastIndexing records the IndexNow request and provider response; Bing controls crawl priority, index inclusion and ranking.
FAQ — Bing Indexing
How do I submit a URL to Bing?
IndexNow lets you send an HTTP notification with the URL and a valid domain-controlled key. You can also submit manually through Bing Webmaster Tools. FastIndexing can send supported notifications in reviewed batches and record the response; Bing decides whether and when to crawl.
What is IndexNow?
An open protocol for notifying participating search engines about new, updated or deleted URLs. Publishers send an HTTP request with a URL and a domain-controlled key. Endpoint coverage and processing depend on the participating engines; receipt does not guarantee priority, crawl or indexing.
Does Bing indexing help with Google?
Not directly. Google has not joined IndexNow and does not receive those signals. Submitting a URL through IndexNow does not speed up, confirm, or influence Google's indexing of that page in any way. If you need to accelerate Google indexing, you need Google's own tools and channels — see /google-indexing for that.
Do I need Bing Webmaster Tools?
Not for IndexNow submission. The protocol only requires a key file on your server — no BWT account, no domain registration in the console. Bing Webmaster Tools is useful if you want crawl statistics, keyword performance data, or sitemap management. For the actual signal that pushes URLs to Bing's crawl queue, it is optional.
How fast does Bing index after an IndexNow signal?
IndexNow notifies participating search engines that a URL was added, updated, or deleted; it does not bypass Bing's indexing pipeline. FastIndexing checks technical readiness, sends only discovery signals applicable to the URL and search engine, and monitors status from D0 through D14. Bing decides whether and when the URL is indexed; no aggregate indexing rate is promised.
