My pagerank for one of my websites went down from a 3 to a 2 than to a 1. The only major thing I did is force urls to start with www. in the .htaccess I was expecting the pagerank to rebound back up to 3 but it isn't anyone know what else might be causing this? Most everything is still the same from when the site used to be a pr3. Only thing that has changed is the .htaccess forcing urls to start with www.
is there any change in google search ranking for your site?? mean to say did the number of visitors you get from google also drop down.
I think you may have lost some good backlinks for your site. Please check whether there are enough links pointing towards your site especially those from high pr pages. Apart from this, I don't see any other factor which affects page rank.
The .htaccess file will not harm your page rank. Me inparticular take no notice of page rank any more. This is usually beneficial for link exchanges, and I do not exchange links. To keep your PR juice into your website, make all your outbound links nofollow. Following links will allow Google to pass on some of you pagerank. Therfor if you have more outbound links than inbound links, your link popularity will drop considerably. Are you ranking good in Google? If not, then your SEO, inbound links and content need review. If you need any other advise, drop me an email.
