I've mentioned this before, but I'll mention it again.
There's a site I did for a friend's retail store 10 years ago. I used a straight text-only page for the SE's, and then had a redirect script that sent users to a light weight page for dialup users, and one with more Flash content for faster connections. All three pages had the same content. Only the text-only page had follow tags; the other two versions were nofollow.
I got the site on page one for many phrases, including "Acme widgets".
When I started my own site in 2004, I had to compete with the site I created for the friend's retail store, and for many of the same phrases. I could never beat it, though.
That site hasn't been touched in at least five years. Most of the models of widgets are out of date. Yet it still ranks #3 for "Acme widgets", as well as other phrases. IOW, the site that was using redirect pages still ranks. The one that was above board is gone.
Makes no sense. I suspect that Google likes it because it's pure HTML with no images or flash or even font tags.
Meanwhile, my pages got wiped out by Panda. Search for my site using "Acme widgets" and you'll have to go to page 12 to page 15 to find it.
