I’ve received this question from several people now. Below are two videos from Matt Cutts who works on Google’s Webspam team explaining how tagging content mostly does not affect their search results. This also means that tagging largely will not affect how results appear on Middlebury’s site, since we use Google to provide our search results.

Tag Clouds
This does not mean that you shouldn’t tag content at all. Tags can still be useful for humans who want to find other posts and pages on a topic. However, if you want your page to be easier to find, your time is better invested in making sure that the content is well written, structured and relevant to a particular topic.
How ironic that you used lots of tags for this post :)
