The canonical URL points somewhere unexpected
1.7%
of the 3,044 free scans considered in the last 30 days raised this finding. That is 53 scans across 51 distinct sites. 95% interval 0.3% to 9.7%.
What it means
A canonical naming a different domain, a different page, or one that could not be read tells search engines to credit the wrong address.
How to fix it
Point each page's canonical at its own final URL on your own domain. A canonical aimed at another domain hands the credit for that page to somebody else.
How to check it yourself
View source and check the href inside link rel="canonical". Compare it against the page's own address and domain.
What fixed looks like
View source shows the canonical href matching the page's own final URL on your own domain.
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.
