Google Webmaster Central

There has been some talk in the last few days that Google is planning to put company logos next to the relevant results.

Hiding under the Google Webmaster Tools "health" menu, the new "Index Status" feature shows you how many pages from your site have been included in Google’s index.

It's almost certain that you have catalogues, brochures or data sheets on your website as PDF files, and these seem to be appearing ever more strongly in Google's results (so long as you don't hide them from your website visitors by making them only available on request).

How Google has made the process of removing a URL from the results a little easier. You do this through Webmaster Tools.

As a website owner, it's very important that you correctly serve up 404s – indicating that someone's on the right domain, but the page they've asked for doesn't exist.
