Hey guys .. I'm currently ranking #4 for a low competition niche. My site is only 3-4 weeks old and I have the EMD.com and I've been at #4 for some time. This niche is quite weak. The top 3 sites are all youtube videos. The #1 has 94 backlinks, #2 has 3 backlinks, and #3 has 34 backlinks. My site has no backlinks and I know obviously adding some will help me, but I'd rather not spend alot of money on backlinks, especially for this niche. What should I do? Tiered backlinks, social bookmarks, blog comments have all came to mine but just thought I'd ask here as I'm new to this and would rather not hurt my rankings somehow.
