No XML sitemap found
18.1%
of the 3,044 free scans considered in the last 30 days raised this finding. That is 550 scans across 542 distinct sites. 95% interval 15.1% to 21.5%.
What it means
Without a sitemap, crawlers rely on internal links alone to discover pages, and deep pages get missed.
How to fix it
Publish a sitemap.xml listing your real pages and reference it from robots.txt with a Sitemap: line. It is how pages with few inbound links get discovered.
How to check it yourself
Open example.com/sitemap.xml directly in the browser. If it fails to load or shows an error instead of a list of URLs, no sitemap exists.
What fixed looks like
Opening example.com/sitemap.xml returns a list of your real pages, referenced from robots.txt.
How we measured this
Go Voltic scans a site and records which findings it raises. The share above is over every free four-page scan in the last 30 days that loaded at least one page, which is 3,044 scans. Deep scans of paid reports and of the research sweep read a site at a different depth and are a separate population, never in this denominator. It is not a survey and it is not an estimate: it is a count of what our own scanner found. Sites are counted once each in the distinct-sites figure, so a site scanned twice does not weigh double there.
The interval is a 95% Wilson interval. A share printed without its sample size reads as certainty and is indistinguishable from a guess, so both are always shown. Figures on this page were computed on 2026-09-08.
The same share sits beside every other finding on the benchmarks page, which also carries the whole table as CSV and JSON and says how to cite it.
Check your own site
The free scan reads four pages and reports every finding it raises, including this one. It takes about ten seconds and asks for nothing but the address.
