Thank you for your answers. My future main blog is still on a local XAMPP server. I think I will take this blog online only when I do have some significant content (blog posts plus some static pages which I consider as sort of my 'flagship content'). However, I do have a 'test' blog which is already online for learning purposes (it is in a similar niche). Funnily enough this blog ranks quite high for certain keyword phrases (and I do get a - tiny - number of clicks

). Of course this blog will be my first source for a backlink (beside social bookmarking). I also wrote some squidoo lenses and hubpages from which I will backlink when I am ready to go online with my main blog.
So I think I can get about 5-10 backlinks within the first 24h (and continuously adding more as time goes by). Do you think that this is a reliable strategy and a 'good' start?
