Search engine spiders which crawl and index your site look at more than just the metatags - they look at the content on your site as well as how well the keywords in your metatags are reflected on your page content. For example, a site about online marketing should have that phrase in its title and keywords, and include words that are related to that discipline in its Meta Tag Keywords.

meta name="keywords" content="online marketing, meta tags, 
search engine submissions, page ranking, search index, ranking, 
relevance, robot, spider, meta description, site keywords, web 
marketing, online advertising, banner ads, advertising effectiveness"
