I recently found a couple of old spam posts on my website that had been there a while, they were a hot spas posting and a proactiv post. My web blog is a technical web blog so this might have been hurting my website. A while ago I did a massive clean out of my old blog comments and some spam postings that had crept onto the website to recover from Google Panda, but if I had a couple of spam posts left over on my website, would these have hurt my SER? I have a PR4 blog, but I want to gain. Does keeping your blog prudently clean of SPAM help with your ranking SER wise? I am thinking yes, but I want to know how much of an effect this has on a Wordpress blog site.
