The Search Engine Blog

Conquering all frontiers, Google will now index forums and other form sites to capture even more information. This can be beneficial for users searching how to information contained in various sites without having to visit each site. Google does state that they will avoid password protected pages. While many forums and form sites are already on Google, this new service will index even more by pretending to be a person. How will this impact your site? Will it start a flurry of activity on your server? Are you silly enough to be on a server that charges for bandwidth?
