Yo guys. How much it takes in your experience for a site to get traffic after backlinks were added towards it?
it's not an exact science. It depends upon a range of factors including how often the forum is indexed. Generally I've found between 48 hours but sometimes a few months or more. Generally the higher the PR of the forum the more quickly a link will get indexed
It really hard to provide a direct answer for your question. That will depends on the quality of the link on where it is placed. I would prefer having backlinks coming from article directories rather than social bookmarks. There are other considerations as such as keywords used. Too many factors come into play. Sometimes you could still rank well without depending on backlinks if you have unique content with the right combination of keywords.
