Report data means everything that is generated when you run a site report: records representing the web pages and all the accessibility and HTML issues found in them. Report results are stored to let you work later on reviewing the issues without relying on real-time checks. Learn about our new report data storage policy.
The new Summary Report gives you a global overview of the status of a site, including the counts of total HTML and accessibility issues found, and a percentage of the total number of web pages that passed all the checks.
