Check copyright dates
Checks that any page containing a copyright date has the correct year, for example pages which have '©2010 All Rights Reserved.' at the bottom will have an error.
Small details like old copyright dates can make readers wary. It may appear that the content is out of date or even that the site has been abandoned. It's a good idea to keep your copyright dates current.
DeepTrawl performs this check by looking for symbols and words such as © or 'copyright'. If they have a date soon afterwards DeepTrawl will make sure the year is current.
