Number and Quality of Backlinks - The number and quality of backlinks is very, very important. This is why, when you are performing a SEO audit, you should check these: Do your backlinks come from reputable sites in your niche? Do you have many unique backlinking domains or do your links come from just a couple of unique domains? Do you have toxic backlinks (i.e. links from bad/spammy sites)? Do you have nofollow backlinks (you should because if you don't, this is very suspicious) Do your backlinks have keywords in the anchor text and are these keywords different from one another?

Position with Recognized Ranking Services - Even if your site has a good backlink profile this doesn't mean it is a good ranking site. In addition to your rankings with Google and the other search engines, one more factor to consider about your position on the Web is how reputable ranking services, such as Alexa, PR, Page Authority, Domain Authority, etc. rank you.

Presence on Social Media - Social media, such as Twitter, Facebook, Slideshare, Pinterest, and the other social networking (and some social bookmarking) sites are a good indicator about your site's popularity. If you have a large following on these sites and a good number of reposts, this is a huge plus.
