Maybe I'm mistaken, but from what I understand so far... meta descriptions are generated on the fly by the plugin which does all the work. The component is just for overwriting.
Without any rules created, just using the settings from the plugin, I managed to get the meta tags generated on the fly out of the box for keywords, title but description is empty?
<meta name="keywords" content="tag1,tag2,tag3,tag4,tag5" />
<meta name="robots" content="noindex, nofollow" />
<meta name="title" content="Sample Advertisement 12 (Gallery) - Site Title" />
<meta name="image" content="
mydomain.com" />
<meta name="copyright" content="Copyright © 2012 SiteName. All Rights Reserved." />
<meta name="description" content=" " />
I tried creating a rule but it seems the rules are only meant for this or that specific page, while I am looking to generate meta tags for all articles from its content automatically. What am I doing wrong? ^^!!
