Some good info here.
Lovely write up mate. I do guest posting too and for me, it is great to build authority. Okay I admit that I see authority building is more important but backlinks. Haha.
Anyway, I always believe write an article that is worth helping others will build more reputation status and indirectly, the chance of getting even more links back.
Have a great weekend and keep up the writing mate. Enjoyed every one of your posts.
