I had started a niche site (health niche) on November, 2014. The keyword was moderately difficult and I was able to find an EMD with .NET extension (keyword.net). At the time of purchase, that domain had 0 backlinks and was NOT indexed but I thought it was Okay because domain was last used in 2011. So far, my MNS has 7 indexed pages and 300+ backlinks from 16 Unique Domains (backlinks were built 3 months ago) but it's stuck on 4th page (#44). Site on #1 position for the keyword has just 20 backinks from 10 domains and most of the results in 1st and 2nd page don't have any backlinks at all. Should I retry with a brand new partial match domain or should I just keep building links to my MNS? Thanks.
