Which Search Engines Support IndexNow? The Full List

If you publish content and wonder which search engines hear about it through IndexNow, this guide gives you the current picture in plain terms. IndexNow is an open protocol co-developed by Microsoft Bing and Yandex that lets site owners push lists of changed URLs to participating engines. Instead of waiting for scheduled recrawls, you notify once and supporters prioritize those URLs for discovery. You will learn which engines support IndexNow, what each one does with your submissions, how to verify the list without relying on stale posts, and how to set up one workflow that reaches every supporter while handling Google separately. The focus keyword for this guide is indexnow supported search engines, and every section ties back to practical setup, verification, and measurement.

Key takeaways

• IndexNow is supported by Bing, Yandex, Naver, Seznam, and others listed in official docs, while Google does not support it.
• One key file at the root plus batched POST submissions can serve all supporters without per engine integrations.
• A 200 or 202 response means received for consideration, not guaranteed indexing, while quality and crawlability still decide outcomes.
• Verify the supporter list against primary sources before you cite it, and plan a separate Google track with sitemaps and Search Console.

What IndexNow is and why engine support matters

IndexNow is an open protocol that lets site owners ping search engines the moment URLs are added, updated, or removed. Instead of waiting for the next crawl cycle, you send a direct notice with the changed URLs, your host, and your key. Engines that support the protocol then prioritize those URLs for discovery. This article maps which engines support IndexNow today, what each one does with your pings, and where Google stands, so you can plan coverage without guessing.

A ping lists changed URLs so engines can discover fresh content in minutes instead of days. That check takes seconds, yet it prevents hours of debugging when submissions seem to vanish. Site owners who log every submission spot patterns faster and fix root causes instead of guessing. Small teams benefit most from this habit, since one clear log replaces several scattered guesses.

Support varies by engine, so one submission does not guarantee identical handling everywhere. Site owners who log every submission spot patterns faster and fix root causes instead of guessing. Small teams benefit most from this habit, since one clear log replaces several scattered guesses. Keep notes on what changed before each submission, so you can link causes to crawl results.

Coverage planning starts by listing where your audience searches, then matching engines to that list. Small teams benefit most from this habit, since one clear log replaces several scattered guesses. Keep notes on what changed before each submission, so you can link causes to crawl results. Consistent process beats bursts of effort, because search engines trust steady, clean signals.

Verification with a root key file proves ownership before any engine accepts your pings. Keep notes on what changed before each submission, so you can link causes to crawl results. Consistent process beats bursts of effort, because search engines trust steady, clean signals. When in doubt, test with a single URL first, confirm the response, then scale to batches.

Logs and Webmaster Tools show whether pings turn into crawls for each supporter. Consistent process beats bursts of effort, because search engines trust steady, clean signals. When in doubt, test with a single URL first, confirm the response, then scale to batches. That check takes seconds, yet it prevents hours of debugging when submissions seem to vanish.

Read the table row by row before you change code, since each row maps to a check you can run today. Confirm the key file is reachable, confirm batches use canonical URLs, and confirm logs show 200 or 202 for recent sends. XML sitemaps give structure and lastmod hints, while IndexNow gives freshness the moment URLs change.

How IndexNow started with Bing and Yandex

IndexNow was co-developed by Microsoft Bing and Yandex as a shared way to reduce wasteful crawling. Before the protocol, engines had to recrawl sites on schedules to find changes. That meant extra load for servers and slower discovery for owners. The shared protocol replaced polling with push, where owners notify engines once and all supporters can act. Knowing this origin helps you understand why Bing and Yandex remain core supporters.

Bing and Yandex launched IndexNow to replace scheduled recrawls with direct change notices. The file name matches your key, for example abc123def456.txt, and it holds the same key as plain text. Search engines fetch this file once to confirm control of the domain, then they accept submissions. Keep the file reachable with a 200 status, plain text type, and no login wall or bot block. See the complete IndexNow protocol guide for endpoint and key details, plus IndexNow documentation for the current spec.

Push reduces server load, since engines crawl what changed instead of everything on timer. Search engines fetch this file once to confirm control of the domain, then they accept submissions. Keep the file reachable with a 200 status, plain text type, and no login wall or bot block. If the key file returns 404 or blocks crawlers, verification fails and submissions are ignored.

A shared key file and endpoint format keeps implementation simple across supporters. Keep the file reachable with a 200 status, plain text type, and no login wall or bot block. If the key file returns 404 or blocks crawlers, verification fails and submissions are ignored. Ownership in IndexNow is proven with a key file that lives at the root of your site.

Early docs and case notes came from Bing and Yandex Webmaster portals. If the key file returns 404 or blocks crawlers, verification fails and submissions are ignored. Ownership in IndexNow is proven with a key file that lives at the root of your site. The file name matches your key, for example abc123def456.txt, and it holds the same key as plain text.

Core design choices still shape quotas, response codes, and key handling today. Ownership in IndexNow is proven with a key file that lives at the root of your site.

Bing and IndexNow today

Bing remains the primary IndexNow supporter for most English language sites. When Bing accepts your ping, the URLs enter discovery and join normal ranking pipelines based on quality and relevance. Submission does not guarantee indexing, but it shortens the wait between publish and first crawl. Bing Webmaster Tools gives visibility into submitted URLs, crawl activity, and index coverage. For sites that depend on Bing traffic or DuckDuckGo routing via Bing, this path matters.

For Bing IndexNow verification, check the official indexnow engines list first, then confirm the host in Bing Webmaster Tools before sending batches. This avoids stale lists and proves which search engines IndexNow submissions actually reach today.

Bing accepts IndexNow pings and prioritizes listed URLs for crawling. Separate IndexNow queues from Google Indexing API queues, since auth and quotas differ. Pace batches to a few requests per minute at first, then scale after watching 200 and 202 responses. On 429, pause and retry with exponential backoff instead of hammering the endpoint in a tight loop.

Yandex and IndexNow today

Yandex co-developed IndexNow and continues to support it for its index. Sites with Russian language content, regional audiences, or Eastern European traffic often see the clearest benefit here. Yandex uses pings as discovery hints alongside its normal crawling, sitemaps, and Webmaster signals. Setup mirrors Bing, with the same key file and endpoint pattern, so one batch can serve both engines. Yandex Webmaster provides crawl and indexing feedback to close the loop.

For Yandex IndexNow handling, use the same key file as Bing and watch Yandex Webmaster for crawl pickup within days. Regional sites often see faster discovery here than on global engines when language match is strong.

Yandex supports IndexNow as a discovery hint alongside normal crawl signals. Use canonical tags to concentrate signals on one preferred URL instead of splitting across variants. Review crawl stats monthly to confirm pings lead to visits, then adjust priority and frequency. XML sitemaps give structure and lastmod hints, while IndexNow gives freshness the moment URLs change.

Regional and Russian language sites often see the fastest practical gains. Review crawl stats monthly to confirm pings lead to visits, then adjust priority and frequency.

Naver support and what it covers

Naver joined the IndexNow supporter list as the protocol expanded beyond its founders. For sites targeting Korean audiences or Korean language queries, Naver coverage adds meaningful reach. Naver consumes the same IndexNow submissions, using your key file for ownership and your urlList for discovery. Practical impact depends on content relevance, language match, and site quality. Owners should still follow Naver Webmaster guidance for verification and sitemaps where available.

For Naver IndexNow results, publish Korean language URLs with clean canonicals and track Naver referrals separately. Language match plus steady submits helps Naver prioritize recrawls without extra integration work.

Naver accepts IndexNow submissions using the shared key and endpoint format. Consistent process beats bursts of effort, because search engines trust steady, clean signals. When in doubt, test with a single URL first, confirm the response, then scale to batches. That check takes seconds, yet it prevents hours of debugging when submissions seem to vanish.

Seznam support and what it covers

Seznam, the Czech search engine, supports IndexNow for its index. Sites with Czech content or Central European audiences pick up extra discovery through this channel. The mechanics are the same, with a root key file and batched urlList payloads. Seznam uses pings to prioritize recrawls of changed pages. As with other supporters, pings help discovery but do not override quality checks.

For Seznam IndexNow pickup, keep batches clean and watch server logs for Seznam bot visits after each send. Czech regional pages with clear internal links tend to get recrawled fastest through this channel.

Seznam supports IndexNow and uses pings to prioritize changed URLs. Ownership in IndexNow is proven with a key file that lives at the root of your site. The file name matches your key, for example abc123def456.txt, and it holds the same key as plain text.

Other engines and services that accept IndexNow

Beyond the named supporters, IndexNow has been adopted by additional engines and services that route through Bing or consume the feed directly. DuckDuckGo, for example, sources results in part via Bing, so faster Bing discovery can improve freshness downstream. Other niche engines and SEO platforms have announced compatibility at different times. The safest approach is to treat the official documentation as the source of truth and recheck it before publishing a fixed list.

To answer who uses IndexNow today, review IndexNow partners linked from official docs and track IndexNow adoption notes by date. New IndexNow partners often route via Bing at first, so Bing pickup is a useful early signal while direct support matures.

Where Google stands and why it matters

Google does not support IndexNow. IndexNow pings do not place URLs into Google search results. For Google, use XML sitemaps, Search Console URL Inspection, internal linking, and content that earns crawls. The Google Indexing API is separate and limited to JobPosting and BroadcastEvent pages, not normal posts or product pages. Planning for Google separately avoids the costly mistake of assuming one ping covers every engine.

The current Google IndexNow support position is no support, so keep Google on sitemaps and Search Console while IndexNow serves other search engines IndexNow partners support. This split keeps launches clean across both ecosystems.

Google does not consume IndexNow, so plan a separate Google track. Tighten internal links and fix redirect chains so crawlers spend budget on important pages. Use canonical tags to concentrate signals on one preferred URL instead of splitting across variants. Review crawl stats monthly to confirm pings lead to visits, then adjust priority and frequency. Background on alternatives is in Google Indexing API alternatives.

How to check the current list without relying on stale posts

Supporter lists change, so build a habit of verifying before you cite or commit. Start with the official documentation, then cross check Bing Webmaster announcements and Yandex Webmaster docs for your region. Look for dates on any list you find, and prefer primary sources over roundups. Keep a short note in your runbook with the date you last verified, the URLs you checked, and what each source said. That note saves debates later.

What happens after you submit to each engine

After you submit, each supporter decides when to crawl based on its own load, trust in your site, and URL priority. A 200 or 202 response means the batch was received, not that every URL will be indexed. Engines may crawl within minutes, hours, or days depending on freshness signals and site history. New domains often see slower pickup until trust builds. Deleted URLs are treated as removal hints, not instant purges, and still pass through normal validation.

200 means received for consideration, 202 means accepted for processing. If the key file returns 404 or blocks crawlers, verification fails and submissions are ignored. Ownership in IndexNow is proven with a key file that lives at the root of your site. The file name matches your key, for example abc123def456.txt, and it holds the same key as plain text.

Practical setup so one submission reaches all indexnow supported search engines

You do not need a separate integration per engine. Host one key file at the root, generate a strong random key, and submit batches to the shared endpoint. Include full canonical URLs, keep batches clean, and log responses. Automate submission on publish, update, and delete events from your CMS or deploy pipeline. Monitor key file availability with uptime checks, since an unreachable key file silently disables verification.

Host one key file at root and keep it reachable with 200 status. The endpoint accepts GET for quick tests and POST with JSON for batches up to 10,000 URLs.

  -H "Content-Type: application/json" \
  -d '{"host":"www.example.com","key":"abc123def456abc123def456abc12345","keyLocation":"https://www.example.com/abc123def456abc123def456abc12345.txt","urlList":["https://www.example.com/new-post/"]}'

FAQ

Does Google support IndexNow?

No. Google does not support IndexNow, so pings do not reach Google search. The Google IndexNow support status has been consistent across official docs, with Google recommending sitemaps, Search Console URL Inspection, internal linking, and steady publishing for discovery. Keep IndexNow for Bing, Yandex, Naver, Seznam, and other supporters, and track Google crawls separately in server logs and Search Console. Check coverage monthly, keep sitemaps clean with canonical URLs, and request recrawls only for priority pages. This split avoids the common mistake of assuming one submission covers every engine.

Which engines should I list as IndexNow supporters?

List Bing and Yandex as core supporters, plus Naver and Seznam, then note additional services that route via Bing or consume the feed. The official indexnow engines list is the source of truth, so recheck it before you publish a fixed list since IndexNow adoption changes over time. For Bing IndexNow and Yandex IndexNow, one key file serves both. For Naver IndexNow and Seznam IndexNow, the same batch applies. Record the verification date, link your runbook to primary sources, and note who uses IndexNow today instead of copying a stale roundup.

Do I need a separate integration for each engine?

No. Host one key file at the root and submit batches to the shared endpoint for all indexnow supported search engines. The same host, key, keyLocation, and urlList format serves Bing, Yandex, Naver, Seznam, and other IndexNow partners. This single pipe design keeps code simple and avoids per engine hacks. Monitor the key file with uptime checks, log response codes per batch, deduplicate repeats before sending, and pace requests to avoid 429 responses. When search engines IndexNow systems fetch your key, they all validate against the same file.

Does a 200 response mean my URLs are indexed?

No. A 200 means received for consideration and a 202 means accepted for processing across indexnow supported search engines. Each engine still decides when to crawl based on load, trust, and priority, and indexing still depends on quality, canonicals, and crawlability. Use Bing Webmaster Tools, Yandex Webmaster, and server logs to confirm pings turn into crawls, then into indexed pages. Track batch time, URL count, response code, and first crawl hit per engine. Review weekly to learn normal lag and spot gaps early.

How many URLs can I send at once?

A single IndexNow request can carry up to 10,000 URLs for all indexnow supported search engines. Use POST with JSON for batches and GET for quick single URL tests. Keep lists to canonical absolute URLs, deduplicate repeats, and pace requests instead of hammering. On 429, back off exponentially and resume after the wait window. Log batch size and response codes, split very large catalogs into dated chunks, and keep sitemaps in sync so supporters see consistent signals. Clean batches get prioritized faster than noisy ones.

How do I prove IndexNow is working?

Submit a small test batch with fresh URLs, log the response codes, then watch server logs for Bingbot, Yandex, and other supporter visits. Cross check Webmaster Tools for crawl and coverage changes within days. Keep a simple sheet with batch time, URL count, response code, and first crawl hit per engine, then review weekly. Compare Bing IndexNow pickup against Yandex IndexNow, Naver IndexNow, and Seznam IndexNow to see which search engines IndexNow activity drives crawls fastest. Stable short lags confirm the workflow is healthy.
