Newsgroup search is becoming very difficult. AltaVista dropped that service over a year ago. A few less well known sites still offer newsgroup search, including newsone.net and nooz.net. For the most part, do not get indexed. If you submit such a page individually, it may get in the index.
Tables are difficult to get indexed properly.
Google gives more weight to pages its webcrawler finds on its own as opposed to pages that are submitted. Fast and Google don't support metatags at all. Excite only supports the description metatag, not key word metatags. Inktomi and AltaVista index both kinds of metatags, but AltaVista gives them no value at all for ranking. In other words, it's hardly worth the effort to write key word metatags.
