Hi Chad,
I think you are asking if it is problematic for all of the pages on your website to be using the same meta keywords and meta description tags.
These tags look like this:
The "content" of these tags, and actually your title tags as well, is duplicated across all of the pages on your website (I am referring to the website listed in your profile - Auben Realty).
The title tag is extremely important and provides search engines with a quick glimpse of what a page is about prior to even viewing the page. These should be unique to each page on your website as they are a page ranking factor.
The meta description tag is not important for search engines, but it is for visitors. This is the description visitors will see when your web pages appear in a search engine's results page. Although this tag is not part of a ranking factor, it is good marketing to have these descriptions be unique to each page.
The meta keywords tag can be removed from all of your website's pages. This tag is not used in any way with Google. I have read that Bing uses this tag to look for basic keyword stuffing. And while other search engines may use the keywords tag for some ranking factor - more than likely you are not getting traffic from those search engines, because they are not used nearly as much.
If you check out the SEOmoz Guide to SEO, you will find additional information on these tags and a bunch of general SEO tips.
Hope this helps.
Mike
