So I have this PR 4 website I have bough since January 2013. I have routinely post new articles on in. Each post takes only less than 24 hours day to be indexed by Google. But I have made my 2 last post since 5 days ago and bought are not indexed yet. My article is unique. NO spun article. I also have submitted to GWT since January and no critical issues. What is wrong? Is it just that I have to wait longer? The last thing I remember to do is I have changed the theme of this website, but after that I have changed again to the 1st theme since it looks better. Any suggestion guys?
