This is a plugin I developed for Textpattern sites that are driven by sections. In order to use this you must take the oldest article of the section and use the ‘custom 1’ field as your list of keywords and the’Excerpt’ textbox as a meta description.
Download the ja_section_driven_meta plugin
Now just call the following in the tags:
which will then output:
<meta name=”keywords” content=”these, are, the, keywords, of, the, section” /> <meta name=”description” content=”this is my description of the section” />
