What it means
Some markup on the page could not be fully evaluated in this pass.
How to fix it
Review every JSON-LD block on the page against the schema.org type it declares, checking required properties and valid syntax by hand.
How to check it yourself
View source and count the JSON-LD blocks on the page, then check each one individually against the schema.org type it declares.
What fixed looks like
View source shows every JSON-LD block on the page reviewed individually against its declared type.
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 90 days that loaded at least one page, which is 5,297 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 2026-09-17.
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.
