Why doesnt google search or index pages in social networks like orkut, facebook,myspace. What stops it ? Do social networks do not want information on profile searchable ? Is privacy the only issue?
...and most of the social network sites have no follow attributes and hence google takes the least care in indexing all the pages from the social networking sites but that is not the case with dp. -Dairyman
Profiles from facebook and friendster ARE searchable on google - unless you've specifically opted out. This is comparatively recent - they used to not be, and when they changed they did inform their users, but I suspect a lot of people have old profiles on those sites, not knowing that they can turn up in google searches now.
What makes you think they are not indexed exactly? I see search results including pages from these sites a lot.
