I looked at the stats of one of our clients sites and noticed a high number of referrals coming from looksmart UK and MSN UK. Obviously my next thing to do was to check the two directories. And to my amazement LS have listed the site, this has definately been done for free. In addition they have been listed under a good description. Which acheives good positions in the results for high traffic phrases.
My site (com/edu) was added to LS free about a year ago. I noticed it when I found hits coming from the MSN directory. I even wrote LS and requested they update the description; it took two months, but it was done! It eventually propagated through all their affiliates.
