FAQ
What is an XML sitemap?
An XML sitemap lists important URLs on your site so search engines can discover and recrawl them more reliably.
Where should my sitemap be?
Many sites use /sitemap.xml and reference it from robots.txt. Larger sites may use a sitemap index with multiple child sitemaps.
Does a sitemap guarantee indexing?
No. A sitemap helps discovery, but search engines decide whether to index pages based on quality, accessibility, canonical signals, and other factors.
Can a sitemap include blocked URLs?
It can, but it should not. URLs blocked by robots.txt, noindex, or broken status codes create confusing crawl signals.
Need the full security picture?
ZeriFlow combines deterministic website checks across headers, TLS, DNS, cookies, and email security with monitoring, reporting, and AI-powered developer workflows where implemented.
