Best IndexNow submission tools, compared
Every option sends the same free HTTP request. What separates them is whether they tell you the truth about what happened next.
Last reviewed 2026-08-21. We build one of the tools compared here; where another does the job better, this page says so.
Short answer
Use what you already have. On WordPress that is the IndexNow feature in Rank Math, Yoast, AIOSEO or SEOPress. On Shopify it is nothing at all: native support shipped in 2025. Behind Cloudflare it is the Crawler Hints toggle. All free, all fine.
Reach for a dedicated tool when the CMS route does not cover you: URLs your CMS does not know changed, a migration where you need to confirm submissions are being accepted rather than assumed, or several sites to keep straight. That is the honest boundary, and it is narrower than most pages on this topic will tell you.
Why "best" is usually the wrong question
Submitting via IndexNow is one unauthenticated HTTP request to a free public endpoint. There is no account, no vendor API key, and no rate card. Every tool below sends the same request; none of them can send it harder. So the interesting difference is not who submits, it is who tells you the truth about what happened afterwards.
That matters more than it sounds, because the protocol makes silent failure the default. The shared endpoint, Bing and Yandex all return 202 Accepted for a submission whose key was never published. They validate the key afterwards, and when that check fails the submission is discarded with no notification to anyone. Naver, Seznam, Yep and Amazon fetch the key during the request and return 403 instead. One broken key therefore looks like success on three engines and failure on four, and a tool that reports the 202 as a green tick is reporting nothing.
The five options
| Option | Who it suits | Cost | The catch |
|---|---|---|---|
| Your CMS or SEO plugin | Almost everyone on WordPress, Shopify, Wix or Ghost | Free | Submits on publish, so it never learns about changes made outside the CMS. Run exactly one. |
| Cloudflare Crawler Hints | Any site already proxied through Cloudflare | Free, every plan | Cloudflare decides when to signal, based on its own view of your cache. You are not driving it. |
| curl from a deploy hook | Developers with CI | Free | You get a 202 regardless of whether the key file works. Verify the key file separately or the job lies to you. |
| Bing Webmaster Tools | Anyone who wants Bing specifically, with quota visibility | Free | Bing only, and a manual interface rather than something that runs on its own. |
| A hosted tool (including this one) | Migrations, multiple sites, URLs the CMS does not see | Free tier here; paid tiers add automation | Nothing it submits is anything the free options cannot submit. You are buying verification and records, not reach. |
What actually separates them
Three questions distinguish a useful tool from a POST with a logo. Does it fetch your key file before submitting, or does it trust the 202? Does it keep a per-URL record of what each engine said, or only a batch-level success flag? And does it check the URL is indexable at all before spending a submission on a page carrying a noindex?
We built this product around the first of those, which is why the pitch is narrow: the key checker and the submitter are free and need no account, and the paid tiers sell unattended sitemap watching and retained delivery records rather than the submissions themselves. If your CMS plugin already covers you, use the plugin.
Platform-specific setup
The traps differ by platform, and most of them are not obvious: WordPress (security plugins blocking .txt, 404 templates served with HTTP 200), Next.js (middleware intercepting the key file, builds running before the deployment is live), and Shopify (where the widely repeated keyLocation workaround is invalid twice over and returns 202 anyway).
