Hey, I'm running a forum with a broad niche and multiple topics that are created by our members. We have a bout 2k daily search traffic, which is good. But I'm trying to get more since it doesn't increase that much during the last few months. So my question is, is it worth to buy link building for a forum? A few friends of me said it's not really needed for a forum, but I want my domain to be placed higher when someone is searching for keywords that are in the thread title. Let me know what you think, thanks!
