Avoid the META keyword tag!

Do not use the meta keywords tag. Many people still think of this as a quick fix for SEO. It’s not. Google no longer uses it. In fact, it is likely that Google penalizes sites that do employ the meta keywords tag. Yahoo is perhaps the only search engine that still uses the meta keywords tag but places very little weight on it.

Death of META Tag

pretty old link though

"In the past we have indexed the meta keywords tag but have found that the high incidence of keyword repetition and spam made it an unreliable indication of site content and quality. We do continue to look at this issue, and may re-include them if the perceived quality improves over time," said Jon Glick, AltaVista's director of internet search.

Answer 2

They're not MATA tags, they're META tags. They are not as important as the actual content of your site and the other sites that link to yours, since it's well known that meta tag content is easier to abuse and misrepresent. Meta elements are more useful in the areas where there is no benefit from such abuse, eg. content encoding or language, but some of this data can be sent by the web server in the HTTP headers anyway. So you rarely, if ever, need any meta elements.

You don't need any sort of technology to 'block' meta tags. Every tag is just a bit of text you insert into your HTML. If you don't want to send out a meta tag, you just don't write it into the HTML.

If you want specific information on how Google views your site then you could start with their webmasters page.
