Hi, after reading alot of articles, getting quality backlinks is key. I know this site has a huge pagerank, and just a question if I put my site in the signature, will it affect my blog positively, as in a dofollow link, or is digitalpoint link nofollow?
The pagerank which you can see in the toolbar is updated only a few times in the year. But the real pagerank is updated every day so as soon as googlebot will find your signature the links will be counted. It may take some time when you will see your website higher in the search results (depending on the keywords you are targeting).
It can take a long time for your links to show up and have any impact. Try some supplementary link building methods too.
dont limit your dofollow links from this forum only... search other forums in your niche or use other linkbuilding tactics and you should be fine.
