any link, as long as it comes from a clean source not a scam site, is somehow good... the more the better?
As I understand it, content links tend to fare better than sig links, at least in terms of building Google PR. Try not to worry too much about Google PR, though. I've seen many PR0 sites rank first in search results, well above PR3-4 sites. But as someone else on this thread suggested, even your best theories about Google algorithms are just that - theories. It's kinda like trying to please one of those fickle old Norse gods...
Backlinks from signatures at DP are mostly good for traffic and indexing purposes. If your goal is to get a high PR I wouldn't recommend running around and buying up tons of sigs, but like I said they are good to pick up a little traffic and get indexed.
signatures in website in DP do help but u know u must contribute first ,which means u are really communicatin with others and offer helps,that's the point really count . not only the number of your posts .
DP signatures are as good as any other forum signatures. They dont give much of pr, but can give good traffic and its good to have good traffic.
I don't know how good it is yet because my posts are still low. But I believe it will help our traffic, cause more backlinks will drive more traffic. More traffic will possible to get high pr. If you have quality post/thread it will help a lot because google will index your thread/post in higher position and the forum members also would love to visit your blogs.
Backlinks from DP are just as good as any other forum signaure backlink. get alot of them, and it will increase your PR
