Signature links are do follow and Google consider it as backlinks, you can check it here http://www.google.com/search?q=link...avclient-ff&ie=UTF-8&rlz=1B3GGGL_enIN260IN261
Of the 1,805 External Links counted at Google Webmaster Tools for my web site -- about 300 of them are from DP.
Check yourself: http://www.google.com/search?hl=en&q=link:hotelsneardelhi.com DP Signlink is counting as a backlink !
google webmasters sees the link but in their polity they don't allow signature links so they don't show the links. searchingcoder
As of today, Google is counting 2,400 External Links......about 500 of them are from DP. (about the same as the number of posts)
Google wont always show your dp links, trust me they are most likely there and counted. Strange that both msn webmaster and Yahoo site explorer do show all these links and Google doesn't. Links to here should only be a support form of linking and not your primary source.
I still can't add a signature! Any idea why? I've been a member for over 7 days and have over 10 posts too!
Probably best you e-mail DP, i cant see anything wrong with your account. If i remember correctly i was able to within 12hrs of my 10th post.
The links are definitely dofollow, and they do help... remember, they are PR0 links, but as you continue to post, the # of backlinks add up!
They are "Follow" links, but I believe there is a popular belief that sig lings have been devalued as much as footer links. I wouldn't base my SEO on sig links, but it can help in adding to the link count. Every bit helps.
Google's Webmaster tool don't show all your backlinks. In additional, Does Forum, you posted, give "Dofollow" signatures.
