Free tool · Fetches your public page

Is your sitemap valid?

A sitemap crawlers cannot parse is a list of pages nobody visits. Enter a domain or the sitemap URL. helloAISearch finds it at /sitemap.xml or through robots.txt, follows up to three child sitemaps, and reports every error and warning with what to change.

Sitemap validator

A domain is enough: we look for /sitemap.xml, then for a Sitemap line in robots.txt. Or paste the sitemap URL.

How this tool works+

The domain or sitemap URL you enter. helloAISearch fetches the sitemap, up to three child sitemaps, and robots.txt when the sitemap has to be discovered from it; nothing is stored. No AI provider is called. No AI provider is called. The public page is fetched from our server, scored, and not stored. Rate limits apply. Details in the Privacy Policy (Free Tools sections) and the Terms of Service (section 29).

One check is a snapshot. A schedule is a measurement.

helloAISearch runs your prompts on ChatGPT, Claude, Gemini and Perplexity on a schedule, highlights every mention, and turns each gap into one move per day.

Questions

About this tool

How does it find the sitemap?+

If you enter a URL that looks like a sitemap it tries that first. Otherwise it tries /sitemap.xml at the site root, then reads robots.txt for a Sitemap line and tries the first two it finds. The result says which of the three worked so you can tell whether crawlers will find it the same way.

What counts as an error versus a warning?+

An error breaks parsing or violates the protocol: no urlset or sitemapindex root, relative loc values, lastmod dates that are not W3C format, more than 50,000 entries. A warning is something crawlers tolerate but that costs you: http:// URLs, cross-host URLs, duplicates, priority outside 0–1. Info notes are facts worth knowing, such as fields Google ignores.

Why does lastmod matter for AI search?+

Answer engines refetch pages they think changed. A sitemap with accurate lastmod dates tells them which pages to revisit; one with no dates, or the same date on every URL, gives them nothing to go on, and a page you rewrote last week may be quoted from last year's copy.

It shows an index but only three children. Where are the rest?+

The tool follows up to three child sitemaps per run so it stays free and quick. The children list shows every child it fetched with its status and entry count; paste any other child's URL to validate it on its own.
