Great achievement mate! Google heavily focus on the content and always looking forward for contents update. nice to see someone tried and got the results...
Nice. That happens to me every time. My posts get indexed in seconds, but they don't rank on the first page. Maybe your keyword competition is too low or you are just lucky.
Google love blogs ! I had a blog and after posting something, after 5 minutes google already indexed my post.
I'm thinking to create a couple blogs. As I read here this will help to make more traffic to my web. Thanks guys for good information!
