Does your sitemap help AI find your content?
Paste your real sitemap.xml below. This checks its structure, URL count, and freshness signals against what crawlers, including AI crawlers, actually look for, nothing fetched, nothing sent anywhere.
- A sitemap is a real discovery signal, not just for search engines, any crawler that actually crawls the web benefits from it.
- lastmod dates are a real freshness signal that tells a crawler what's worth re-checking first.
- Paste your sitemap.xml below. It checks whether it's valid, how many URLs it lists, and how many have lastmod dates.
Why a sitemap still matters when AI is doing the reading
A sitemap.xml file is a plain, structured list of a site's real pages, built for crawlers rather than people. It predates the current wave of AI search tools by two decades, but the real job it does, telling an automated visitor what exists and when it last changed, hasn't gone away. A crawler that builds its own index of the web (rather than only answering from a model trained on someone else's index) still has to discover pages somehow, and a sitemap is the most direct, least ambiguous way to hand that over.
The part that's easy to get wrong isn't whether a sitemap exists, most site generators create one automatically, it's whether it actually carries useful signal. A sitemap with a thousand URLs and no lastmod dates tells a crawler what exists but nothing about what changed, which is a real, missed opportunity to get fresher content re-checked sooner.
Check your own sitemap
Pre-filled with an example that mixes pages with and without lastmod, replace it with your own.
What "good" actually looks like here
A well-formed sitemap is valid XML, uses a real <urlset> (or, for larger sites, a <sitemapindex> pointing at several real sitemap files), lists real pages worth a crawler's time, and gives most of them a <lastmod> date that's actually updated when the page changes, not a static date stamped once and never touched again. None of this is exotic, it's just easy to let drift once a site's own CMS or static-site generator is left on its default settings.
A note on very large sitemaps
If a single sitemap is tracking an unusually large number of URLs, it's worth checking whether it's grown past what one file should reasonably hold. The standard answer for a site that large is a sitemap index: one small file listing several real, separate sitemap files, rather than one enormous one. If you're not sure whether you've hit that point, that's a real sign it's worth checking your own sitemap's size specifically, rather than guessing.
FAQ
Does this fetch my real sitemap.xml?
No, paste the raw text yourself. Nothing is fetched or sent anywhere; the check runs entirely in your browser.
Why does lastmod matter for AI visibility?
lastmod is a real freshness signal. Crawlers, including AI crawlers that actually crawl the web, use it to decide what to re-check first. A sitemap with no lastmod dates gives them nothing to prioritize.
What if I have a sitemap index instead of one file?
That's a real, normal setup for larger sites: a sitemapindex file lists other sitemap files instead of listing pages directly. Paste one of the actual leaf sitemaps if you want the page-level checks above to run.
Do I need a sitemap for AI engines specifically, or is this just an SEO thing?
It started as an SEO and crawl-discovery mechanism. Any AI crawler that actually crawls the web, rather than only answering from a pre-built index, benefits from the same real discovery signal a sitemap already gives search engines.
