Ya, they do bring but most of them don't care about your site and just come and go from there. - Digital -
get some friends in orkut.. update the status with yr website link.. you will surely get some traffic
They are a good part of your overall web marketing, but not a stand alone solution. you should have a balanced attack across the entire www, not just social networking platforms.
It works if you are a moderator or owner of real big community or if you can get your websites name in the description of the community only then ORKUT is useful.. apart from that its a complete waste
I own a good community in orkut Link: http://www.orkut.co.in/Main#CommTopics?cmm=43119826 HTML is enabled in it. So you can add your web links as signature in discussions.. I am using it and getting some daily hits in web and ads from there.. You can also do the same.. Just read this: http://www.orkut.co.in/Main#CommMsgs?cmm=43119826&tid=5352233569632748376
yes they will help but now days I prefer a social network site called eZdia (www.ezdia.com) , it is a site which helps you to make aware about your site to different experts around the world and this helps you greatly bringing the good traffic at your site. Also if you are a freelancer it helps you to earn money. You will like to have a look at eZdia today itself if not done yet
Yes, all social networking site are good if you know how to use them, Orkut and Facebook also good, you can use Myspace and twitter also
