How to read this report
The sentences under each heading are filled from the latest snapshot. If a collector had nothing to say, that sentence is left out. The target site's own title and meta description, when shown, are quoted as measurements. They are not this page's title. Change history only lists a difference between two snapshots, so the first check starts the clock and later edits are the history. A malware blocklist is the only reason the homepage body is skipped. That fact stays on the report. It does not by itself drop the page from the sitemap or from related-report links.
