Tell search engines about changed pages with IndexNow

IndexNow tells search engines that a page changed, so they recrawl it sooner instead of waiting to find the change on their own. One submit reaches Bing, Yandex, Seznam, Naver, and Yep. Bing's index also feeds Microsoft Copilot's answers. Google doesn't use IndexNow. To check a page in Google, see Inspect a URL.

Submitting doesn't guarantee a page gets indexed. It tells the search engine the page changed.

Check whether your site already submits

Some platforms submit to IndexNow on their own every time you publish:

• Cloudflare, with Crawler Hints turned on
• Wix
• WordPress SEO plugins with IndexNow built in, such as Rank Math

If your site uses one, leave it on. You can still set up Mark's key to submit pages yourself. A site can have more than one IndexNow key.

Host and verify your key

Mark gives each site its own IndexNow key. To prove you own the site, you host the key in a file on your domain. Mark can't edit your site, so you or your web team add the file once.

1. In the sidebar, select Presence > Websites, then the site, then the Indexing tab. IndexNow is below Inspect a URL.
2. Copy the File to host address. It looks like https://<your domain>/<key>.txt.
3. Create a plain text file with that name that contains only the Key, with no other text. Put it where that address serves it:
   • Site built from code (for example on Vercel or Netlify): add the file to the folder your site serves from its root, often public. Deploy the site.
   • WordPress: upload the file to the folder that holds wp-config.php, using your host's file manager or SFTP.
   • Site builders that don't let you add files at the root of your domain: you can't host Mark's key. Use the builder's own IndexNow support if it has one.
4. Open the File to host address in a browser. You should see only the key.
5. In Mark, select Verify key. Mark fetches the file and shows Verified, or what went wrong:
   • "returned HTTP 404": the file isn't at that address yet.
   • "does not contain exactly the key": the file has other text in it.
   • "redirects off": the address redirects to another host, for example from example.com to www.example.com. Host the file on the domain itself, or change the site's domain in Mark to the one that serves your pages.

Once the key is verified, the key, the file address, and Verify key fold away. Select Show setup to see them again, for example to verify again after moving the file.

Submit changed pages

Submit a page when you:

• publish a new page
• change a page's content
• delete a page (it should now return "not found")

Don't resubmit pages that haven't changed. IndexNow rate limits sites that submit the same pages over and over.

1. On the IndexNow block, paste the page addresses into Submit URLs, one per line. Every address must be on the site's domain, up to 100 at a time.
2. Select Submit URLs.

Last submits lists your 10 most recent submits: when, how many URLs, and IndexNow's answer.

• HTTP 200: IndexNow took the URLs.
• HTTP 202: IndexNow took the URLs and will check your key file first.
• HTTP 403: IndexNow couldn't read your key file. Select Show setup, then Verify key.
• HTTP 429: IndexNow is rate limiting this site. Wait before submitting again.

Submit from an AI agent

An AI agent connected to Mark can submit for you with Submit URLs to IndexNow (submit_urls_to_indexnow). For example, ask it to submit the pages you published this week. It checks your key file first and takes up to 100 addresses on one site. See Use Mark from AI agents to connect one.
