9 Meta Tag and Google bot

[firefoxin]

Hi

I have the following meta tags in my page:

1-<meta name="description" content="......" />
2-<meta name="important" content="domain" />
3-<meta name="keywords" content=....... />
4-<meta name="revisit-after" content="7 days" />
5-<meta name="copyright" content="domain.com" />
6-<meta name=robots content=FOLLOW,INDEX />
7-<meta http-equiv="content-type" content="text/html; charset=\$stylevar[charset]" />
8-<meta http-equiv="cache-control" content="no-cache" />
9-<meta http-equiv="pragma" content="no-cache" />

Could anyone please tell me if they are all useful for GoogleBot? should i remove some of them or just add any new meta tag?

Thanks in advance

#1 and nothing more for googlebot. #3 may be used by Yahoo.

Sorry tedster, I must disagree.

After all of the threads about duplicate content a properly constructed number 6 can stop a site from looking like spam city. However there is no need to specify the default robot action via meta robots.

#1 is important and each page should have a unique description that accurately describes that pages content.

#3 I have seen used (in a minimal way) with some smaller engines so I tend to include this with 5-6 keywords that best sum up the page. (I did notice Yahoo using a common misspelling that was only listed in this tag for an uncompetitive keyword.)

#6 is useful if you want to limit or disallow pages from being indexed or archived (nofollow, noindex, noarchive). Setting follow, index isn't needed since that's the default behavior.

#7 is strongly recommended [w3.org] unless you are sending the charset information at the server level [w3.org].

Another that Google (and MSN) uses that might be of interest is <meta name="robots" content="noodp">, that tells them to not use the ODP description of your site in the SERP.

A base href tag helps to prevent search engines from attributing your content to a hijacker/scraper.
