"These meta tags are too vague, and there are way too many."
(Repeat a particular word too often in the meta keywords tag and you could actually hurt your chances of ranking well.)
These meta tags are non-existent!"
(Although spammer abuse of the meta keywords have forced most search engines to de-emphasize their importance, they should not be left off of your page. They actually are considered in the overall equation of your search engine ranking by several search engines.).
"These meta tags are JUST RIGHT!"
(These are the perfect word to use to let engines know the most important topics of any of your pages. Use a few words at most, all comma-separated).
