You should keep your web site up to date. One task, which I have just completed, is to check that all your external (and internal) links are still alive. There’s nothing more unprofessional looking than clicking on a link to see it go to a 404 page.

The other task is to check how your affiliates are doing. There are a lot of mergers of affiliate programs and many disappear. They don’t let you know this necessarily. I’m having to go through many of my links  on ozwebhub to delete old ones and to change code for affiliates I recommend.

I use Xenu Sleuth as a link checker. Often makes mistakes, but that’s easy to check. Link checkers are not much good for blogs which are ‘no folllow’ however, as all those blogs will show up as ‘not found’.
