I moved my site to a new hosting company with the same address. Suddenly after a month of having my new site up and running with about 25 pages and new keywords my Pagerank has gone down. There was 2 to 3 weeks where I had no anchor text on the site Does anyone have ideas. If I had known this was going to happen. By the way for what it is worth over the past 6 months my pr got better. I had about back links and directory submissions and done many article directory submissions and some regularly submissions manually. On the purchased regular directory submissions I got confirmation direct from these directories that I was excepted via email. With that let me know if you know what could have happened.
In my opinion it's just the crazy google dance that goes on. I'm not an SEO wizard though so take this with a grain of salt. I had a site that was increasing PR every update, then this last one came, and I know i increased some mad links into the site, but it went down. Who knows is what I say. Maybe IP matters if you change it but...?
From SEOP.ru : What speak about Google datacenters in the internet? The Internet in general that in itself is an excellent source of the information, after serf on various sites, it was possible collect the following information from different places: To Google datacenters different sources during different time carried IP addresses with the following endings: 44, 80, 91, 99, 104, 115, 147, 184, 214 Till 2004 datacenters Google had own domain names of type: www-XX.google.com, where XX - two symbols from the english alphabet, besides presumably, subsequently these addresses were changed on addresses of type: gfe-XX.google.com (that is understood under GFE - opinions miss, most plausible of met by me - "Google Front End")
Sometimes page rank is not accurate. Don't bother yourself with your site PR. The most important thing is to get higher ranking on major search engine.
