interesting piece of experimentation. this only confirms what we've been thinking all along though - directory submissions are by far not the fastest nor the best method to gain PR and traffic. we routinely go from zero to 1000+ unique visitors/day within one month of launching a new site - with no directory submissions. you just have to build a different kind of site, with lots of deep pages, aiming for longtail traffic right away.
Thanks for sharing your experience. Like others i was also thinking that may be after updation in Panda, directory submission is of no use. But your experiment is telling some different story. Thanks a lot for sharing this.
You have spent a long time on your experiment. Everyone now would be sure if they need to go for a directory submissions or not. Great work.
That's very interesting, Torafox. I'd love to know how you can get more than 1000 visitors in a month. Is it really that easy? I am sure it must depend on the field you are working in. I run a translation website and there is not as much natural interest among the common people to search for these terms.
Nice experiment, thanks for sharing. I wonder if some of the directories hurt ranking, shame google doesn't give us more insight.
