This is an authority site. But is also known as a site where webmaster can place freely their links on their signatures. Google knows that this forum follow links. Pratically, every one that reaches certain number of posts, can place their links here even pharmacy, gambling and porn sites. That is something that Google do not want.
Beside signature links, links in DP directory are also dofollow, http://directory.digitalpoint.com/. - Dynashox -
dpforum is DoFollow. There is a great FireFox plugin through which you can easily track DoFollow and NoFollow links. Check it http://www.epiki.com/easily-track-dofollow-sites-with-firefox
I believe google give less priority to forum signatures these days. Its has little or no effect on the ranking.
And check the PR of DP. It has no change since it was down graded to PR4. Don't expect get any pr transfer from DP.
I think you are right, maybe google do it because of that. Any experience that a site PR go up after you backlink in the signature here?
Is that so? I didn't actually use google to find the backlink but my yahoo explorer counts it as backlinks.
All you have to do it look at the source code of this page. How could you possibly not know that if you have a website?
I do not think there is any limit of do or nofollow as i have joined with DP, all my links are dofollow but i never care about it. what i want from DP is building a good relationship with others and sell my service to serve people only.
