I have been seriously neglecting the meta tags in my Movable Type blogs. In fact, other than the requisite content type declaration, I haven’t been using meta tags at all. That change today when I finally added entry excerpts into the meta descriptions.
After the first test, I noticed that there was a slight problem. If the excerpt contained quotes, they were not escaped in any way and invalidated the page. Brad Choate’s MT Regex plugin saves the day again:
<meta name="description" content="<$MTEntryExcerpt regex="dequote"$>" />
