Help > Trawling pages which have not been updated recently

What does this trawl type find?

Keeping your information, layout etc. fresh and up to date is essential to keep users interested and present a professional appearance.

This trawl type will return a potential problem for any page which has not been modified within a specific time frame, which can be set by you.

The last modified date is taken from the HTTP header for pages found on the internet and from the file system for local pages.
