Have you noticed that all those hosting website's PR , almost all PR5,6 even 7~~ hostgator, bluehost, dreamhost....... why the PR of these sits are so high???
When you newly register a site, the hosting company adds a page of its own. This helps them get a lot of links, also they are making money so they would want to have the highest amount of presence on web. Their PR ultimately increases with their press releases and talk about them .. irrespective or it being good or bad.
I'm trying to post more press release for my site, and provide more free service so others can talk my sites and post the link everywhere.....
Most large hosting companies spend a lot of money on internet marketing.. the PR doesn't come from out of nowhere
They know how to game the system and get backlinks All you have to do is hunt for links, build a relationship with website owners, and start marketing your brand, product and business where your market is.
they are well known hosts. big companies, not just hosting companies, spend millions in marketing campaigns. amount of media coverage they get along with the backlinks form news/press release sites can drive their PR high. also, lot of people just link to them for the sake of it anyways so getting high PR for those sites is not unusual.
