Im in the process of editing a few websites for uploading to directories and engines. Im aware of most if not all techniquest to "attempt" to achieve the best ranking, however its my understanding that many engines that use one technique to index a page may completely be ignored by another engine for using that same technique.

Is there any sites that tell you for example what engines use keywords, which dont, which engines allow doorway pages, which dont, and so forth?

Thanks,

Also look at www.searchengineworld.com
