How do I get a new blog to rank high on search engines? It already has a few posts with quality content.
Sorry, but that question is far too broad and vague, and will only attract general responses, as you can see.
I suggest you download Google's Search Engine Optimization Starter Guide to begin with, and also have a look at some of the sticky threads and other threads in this forum, which contain a wealth of information.
If, after that, you have a specific question which has not been answered, please feel free to start a new thread. Meanwhile, I'm closing this one.
