SEOSimple - easy SEO plugin for Joomla - Nocean
The SEOSimple plugin automatically generates the meta description tag on page load by taking a customizable length of text from the start of a page's content. Should you already have a custom meta description assigned to the article (as set in the Metadata Information box in the article editor), the auto-generated tag is ignored and the custom one is used. Additionally, the plugin gives you several options for displaying your page titles, as well as the ability to easily customize the behavior of the plugin on the site's front page.
