Welcome to WebmasterWorld Guest from 18.104.22.168
There is a Google update in full swing at the moment.
Now would be the right time to make sure that you do:
- return a status of 404 for pages that do not exist
- redirect all non-www requests to www for all pages
- check all your internal links for problems
- have a trailing / on all links that point to folders.
Use WebBug and Xenu LinkSleuth to look for problems.
