Recently launched a website on a micro niche and finding it difficult to find place to build back links. I am doing it manually as of now. search Google for my niche and looking for blogs and forums to put links at. Almost everything I am finding is nofollow links and that's if my links don't get removed.
How would you all recommend I build my link profile and how many of these links should I focus on for now? Thanks!
EDIT: I keep hearing about web2.0 sites. what exactly is a web2.0 site. I know this is a newbie questions so my apologies.
