We’ve created a WordPress Plugin which adds site-wide Keyword and Description meta-tags. We’re using it on this web site!
The process is simple: define some site-wide description and keyword meta-tags. These will be used everywhere unless you (or your authors) choose to append keywords or override them completely for a particular post or page.

Add Meta-Tags to your site, and customize them on a post-by-post basis

This is a plugin for the FeedWordPress.
You can do complicated keyword filters using AND, OR, and NOT logics. Plugin will look for user entered keywords in post_title, and post_content
<h3>Usage</h3>
It is not disabled out of the box and you should add keywords by clicking the Add a new keyword filter. You can add as many keyword filters as you want using one or all of the logics [OR, AND, or NOT]
You can add keywords for individual feeds as well. When you select Posts under individual feeds on the Syndication menu of FeedWordPress, you’ll have the same options to add keywords.
<ul>
<li>
Keywords are not case sensitive. Enter comma seperated list of words along with your selection of logics.
</li>
<li>
Do not leave extra space between words – unless you want it. The exact spacing will be matched.
</li>
</ul>
