What it does: tells search engines that use the IndexNow protocol which URLs of your site changed. SerpUp can send to IndexNow, Bing, Yandex, Naver and Seznam; IndexNow is the default.
Set up:
- Open the site's Indexing section, then IndexNow, and choose Generate a key.
- Publish the key file at
https://your-host/<key>.txt. The page shows the address and the exact content the file must contain. - Choose Verify. SerpUp checks the key file through its crawler. The state is
unverifieduntil the check passes andfailingif a check fails; the page shows the reason.
Submitting: URLs can be sent only after the key is verified. Each URL must belong to the site; others are rejected as wrong_host or invalid_url. A URL sent in the last 10 minutes is skipped unless you force it. One request carries at most 10,000 URLs, and a daily limit per site applies (counted in UTC); a send that would pass it is cut short and reports that it was partial. The History section lists each submission with the status each engine returned.
Follow-up: 48 hours after a send that reached at least one engine, SerpUp queues a Google inspection of a sample of the URLs so you can see whether it helped.
