This tool checks how fresh your page’s content is by examining two primary signals:
Last-Modified
HTTP header, which most servers provide.article:published_time
or datePublished
.
For example, if the page’s Last-Modified
header is "Wed, 15 Feb 2023 14:30:00 GMT"
and today's date is "Wed, 15 May 2023", the tool will report that the content is roughly 90 days old
and advise an update if a fresh perspective is needed.
