Hey guys, I've been around for nearly a year now, but not long ago I've started improving my SEO skills.. I have a simple question: I've started a blog and everything I do is whitehat, I've started doing some manual Yahoo answers, and submiting my article's links as source.. I'd like to know how long does it usualy take for a backlink to be taken into consideration when ranking on serps? Also, where do you suggest I should do these kind of off-site seo more? Yahoo answers, Youtube, somewhere else maybe? I'm looking forward for your replies, thank you a lot!
