Hi I have a newbie Q, that is I have the 3 sites link in the Signature and i have total 453 Post in DP is that miens I have Total 453 Link for Each site? or allover counted one link? Actually My Question Is if i put my link in a site 100 times in different different page That have any benefit?
Yes, you have 100 links (you can check the number of links counted by google in the google webmasters tools). But for purpose of increase in Pr links from the same site (or the same class ip)don't count too much.
Agreed. Even though I have 1900 posts, about 1,000 show up in Google Webmaster tools. Having so many from one domain offers little SEO weight. Join some other forums, submit to directories, submit to social bookmarking sites, write and submit a few articles, and comment on blogs. Those are free backlinks.
If you check your back links using Google tool bar, you may have noticed sometimes it says at that the duplicate results have been omitted. So I would assume that although the links are accounted for Google does not give importance to duplicate links or links originating from the same IP. Might as well have just the one. However having links in multiple posts (via signature) increases the frequency of Indexing (in case the forum does not have 'no follow' attribute). Every time the forum thread is crawled, which happens frequently, it is more likely that your website would be crawled too. Hope this helps.
Each post counts as a backlink, so basically if you have 100 posts you have 100 back links, but remember you won't get much PR from DP because it's the same Class C IP, AND there are a ton more links to other sites on the same page.
