i wanted to bring this to everyones attention. Many directories that say they are seo friendly are not w3c compliant. sites can check to see if they are valid here http://validator.w3.org/ from my research, having improper code can limit some of your pages and content from being index. here is my partial list of w3c compliant seo friendly directories http://www.dmoz.org/ http://www.excellentguide.com http://www.beaconpost.com/ if you have any or know any more list them here
That's nice that you wanted to proclaim to the world that your directories are w3c compliant, but the only problem is this: Only your homepage validates. The pages with listings on them have many, many errors. But I am sure you already knew this. The reason you see few directories passing validation is because of all the codes that the validator has problems with, such as javascript. And with your directories, the validator really hates those links with the "&id=34324" stuff in them. But w3c compliant does not neccesailry mean a site is SEO-friendly. And many sites that people would consider SEO-friendly are not w3c compliant. Hell, just look at the big reason people spend so much time with SEO: Google. It doesn't come close to passing validation.
My directory www.index-it.net is w3c compliant and member of w3c compliant websites. And although I do not think that you have to have your site validated it is still a good idea to do so.
my pages pass. ALL of them. woowoo!!!! i am currently goofing in the directory so you might get a few things here or there. but once i am done they always validate. derek, as far as things like "&id=34324" just use it's encoded version. like & is the same as "&id=34324" and will validate no probs.
