I am running a blog (link in signature) with no real niche and does not focus on anything in particular is this ok or would I be better off focusing on something such as web design? Thx. .
It's definately better to focus on a certain topic in your blog. This will not only give you better ranking in Google, because your pages have a higher keyword density, but also the Google Adverts (if you use any of them) will perform better. This because they'll have an easier task finding the theme of your blog...
