Hi,
I've never been involve in SEO, or chasing tricks to artificially optimize the ranking of my site (I am just trying to make my site the best I could, and happens what happens).
However, I thought I could share my story about an "accidental" traffic booster :)
So it was in the old times, when PageRank was THE main ranking factor at Google, elders will remember the Google toolbar with the little green rectangle :) . So back to that time , all was a matter of PageRank, which was connected to backlinks and the way each link was carrying a fraction of the PageRank to the next page.
So the goal was to get a link from a page with a high PageRank, and, if possible, this page should have had a limited number of outgoing links. There was an ultra easy way to achieve it, free, and nearly instantaneous. At that time, there was the attempt of the P3P protocol [
en.wikipedia.org...] , and they had a page, listing P3P compliant sites... So you just had to create the P3P files (correctly), and submit your site and they were listing it ! The P3P's site front page had a page rank of 10 , and the page, listing compliant sites, had a PageRank of 9 ! Very few webmasters minded this new protocol , when i submitted my site, there were only 4 other sites listed! Also, articles being written about the P3P protocol were listing sites already compliant as examples, including mine, with a direct link!
As a result, my site 's font page, went from a PR of 4 to a PR of 7 ! and my traffic doubled from one day to another, two months after my site was listed on the P3P site (it was the time Google had a monthly update).
The old good times :)
