No article or breadcrumb markup
77.6%
of the 3,044 free scans considered in the last 30 days raised this finding. That is 2,362 scans across 2,340 distinct sites. 95% interval 75.9% to 79.2%.
What it means
Article and breadcrumb structured data help an answer engine place a page within the site and credit its authorship.
How to fix it
Mark up long-form pages as Article and give every page below the home page a BreadcrumbList, so an engine knows what a page IS and how a reader would reach it.
How to check it yourself
View source on a long-form page and search for the words Article or BreadcrumbList inside a script tag. If neither appears, this markup is missing.
What fixed looks like
View source shows an Article or BreadcrumbList block naming the page and its place in the site.
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.

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.
