Illusive yahoo SERPS

Hello all,

I have a few sites I am currently working on. I have good placement within the Google index for a number of keywords but I have found my Yahoo (and msn) SERPS are terrible. I admit, I have coded the pages with Google in mind but doesnt Yahoo also appreciate SEO friendly pages?

Are there any tricks to getting better placement in the Yahoo directory? Any comments would be greatly appreciated.

Thanks and take it easy,
Dave from TPCS
