A really simple way to alter content to boost page ranking.
Google bot is a funny old animal. Back linking with link farms is now next to useless and the only way to get good links is the old fashioned way 'HARD WORK'. However you can give yourself a bit of an edge.
Google checks whats altered since the last visit. The more it's altered in theory, the more interesting the site. So all you have to do 'in theory' is reword the content on the page every time google visits and your laughing. All you need to know is a bit of php.

Here's how it's done.... Make a few html pages with more or less the same content but altered slightly, and call them say
mytext1.html mytext2.html etc.

Then put this in the actual page you want your text to appear.

Thats it! You can use this for as much or as little content as you require. It's also a good way to rotate customer testimonials.
