What about building backlinks?
This is like the most important job in this process, together with quality of the articles, easy access of your website and ad placements.
Could you elaborate please?
You could have articles written by Tolkein but with modern google you would get nowhere without backlinks. Google ranks your website based on 2 main things, quality and backlinks. You can have the best articles ever written but unless there are other sites out there pointing towards yours google will just assume your site is crap. On the other hand you can have pure duplicated content but if you have brilliant backlinks google will love you. Check out some of the pure blackhat journeys on here for examples of people just taking the RSS feeds from other sites and adding backlinks yet banking hundreds/thousands.
Are you doing anything with social media yet to promote your site?
No, I haven't even considered it to be honest. Should I be?
