IndexNow vs Google Indexing API: Which Should You Use?
IndexNow and the Google Indexing API get mentioned in the same breath so often that it is easy to assume they are two versions of the same thing: a fast lane past the sitemap queue. They are not. They belong to different search engines, accept different kinds of pages, and fail you in different ways. Picking between them starts with an awkward fact that most comparison posts bury: for the ordinary Google-focused site, neither one is officially meant for you. This post lays out what each protocol actually does, who is allowed to use it, and what a sensible setup looks like once you accept those limits.
What IndexNow actually is
IndexNow is an open protocol for telling participating search engines that a URL has been added, updated, or deleted. You host a small key file on your domain to prove you control it, then send URLs by a simple GET or POST request. A single POST can carry up to 10,000 URLs, and a ping to one participating engine is shared with the others, so you notify them all at once.
The important word is participating. Bing, Yandex, Seznam.cz, Naver and a handful of other engines accept IndexNow pings. Google does not appear on the protocol’s list of participating engines, and a ping sent through IndexNow creates no obligation for Google to do anything at all.
There is a second limit worth stating plainly, because IndexNow’s own documentation states it: a ping is a hint about a change, not a command. The receiving engine still decides whether to crawl the URL, and whether to index what it finds. Submission and indexing are two separate events, a distinction that costs real money when you blur it, and IndexNow only touches the first one.
What the Google Indexing API actually is
The Indexing API is Google’s own push endpoint, so it sounds like the obvious answer for a Google-focused site. Read the first paragraph of the quickstart, though, and the scope is narrow: Google states that the Indexing API can only be used for pages containing JobPosting structured data or BroadcastEvent livestream markup. Job boards and livestream pages have short shelf lives, and the API exists so those specific pages can be crawled and dropped quickly.
Plenty of tools and scripts use the API for ordinary pages anyway, and plenty of tutorials show you how. Sometimes a crawl follows. But you are then relying on behaviour Google documents as out of scope, on a quota designed for a different job, and on Google continuing not to care. Google has said it may take action against spammy use. Building your indexing workflow on an API whose terms exclude your content is a fragile foundation, whatever this week’s results look like.
For everything else, Google’s documented routes are the ones you already know: a sitemap for discovery at scale, and the URL Inspection tool in Search Console for asking Google to recrawl individual URLs, one property and one login at a time.
IndexNow vs Google Indexing API, side by side
| IndexNow | Google Indexing API | |
|---|---|---|
| Who listens | Bing, Yandex, Seznam.cz, Naver and other participants | Google only |
| Google coverage | No | Yes, within its scope |
| Eligible pages | Any URL on a verified host | JobPosting and BroadcastEvent pages only |
| Setup | Key file on your domain | Google Cloud project, service account, Search Console owner access |
| Batch size | Up to 10,000 URLs per POST | Per-URL requests under a daily quota |
| What it promises | The engine is notified | The page may be crawled |
Two rows in that table decide most real cases. If your traffic comes from Google and your pages are not job postings or livestreams, IndexNow does not reach the engine you care about, and the Indexing API does not officially accept your content. The comparison is genuinely useful only for the site that gets meaningful Bing or Yandex traffic, where IndexNow is a cheap and legitimate win, or the job board, where the Indexing API is exactly the right tool.
So which should you use?
Use IndexNow if non-Google engines matter to you. It takes an afternoon to implement, many CMS platforms and CDNs can send pings automatically, and it does what it says for the engines that participate. Just do not credit it with your Google results.
Use the Indexing API if, and only if, you publish job postings or livestream pages. Inside that scope it is fast, documented, and supported. Outside that scope, treat every tutorial promising otherwise with suspicion.
For ordinary pages aimed at Google, the honest baseline is a clean sitemap, sensible internal linking, and recrawl requests for the URLs that matter most. When you have more URLs than patience, a submission tool can push them into an indexing pipeline in bulk. That is the delivery half of the problem, and delivery is the easy half.
The question neither protocol answers
Whichever route you choose, you end up in the same place: you have told a search engine about your URLs, and you do not know what happened next. IndexNow confirms the ping was received. The Indexing API confirms the request was accepted. A sitemap just sits there. None of them tells you whether the page is actually in Google’s index today, and none of them will mention it if a page quietly never makes it, the pattern behind statuses like Discovered, currently not indexed.
That gap is the part worth instrumenting. This is where a tool like AIndexify sits: it submits your URLs (up to 10,000 per batch, pasted or uploaded as CSV) and then checks each one against live Google results on a fixed schedule over the following days, reporting submitted and indexed as two separate events with dates. If a URL could not be checked because a noindex tag, a robots block, or a 404 was detected up front, it says so and refunds the credit rather than billing a check that could not mean anything. Submission stops being the end of the story and becomes the first data point.
If you want the wider picture of how discovery, crawling, and indexing fit together, the complete guide to Google indexing walks through the whole pipeline these protocols plug into.
The short version
IndexNow is real and useful, for engines that are not Google. The Google Indexing API is real and useful, for pages most sites do not have. Everything else is sitemaps, patience, and verification. Choose the protocol that matches your engines and your content, then measure the outcome instead of assuming it.
Whichever way you submit, the index has the final word. Submit your URLs and see where your pages actually stand, with dates rather than guesses.
