Analysing Your Keywords for Blogging
A good way to keep bringing back traffic to your blog is to analyse your keywords that are being searched. What it is that brings people there in the first place? By adding a simple free tracking tool to your site such as Statcounter, Extreme Tracker or OneStat you can see what words people are using to find your blog and start writing more articles along those lines. Your blog becomes a hybrid of what it is that people are looking for and you can cater to those keywords.
If you want to pay for a tool there are all kinds of options and maybe once you start to make some real cash from your site you will want to go that route, but in the meantime a simple free tool would work.
