TagMeta generates meta keywords using your most used tags. 
It automatically gets the 10 most used tags out of your 
blog posts and pages and puts them into a valid meta- 
keyword string. This string then appears in the header of 
the home page of your theme. If you want to add tags per 
post, i suggest youre going to use the Headspace plugin.

This plugin lets the user write a separate description for each post, page, front page or custom post type post which is added as a meta description to the html head.
The individual description for a post or page is typed and edited in a separate text field just below the text field for editing the post text.
You can also add meta description to category, tag and custom taxonomy archive as well as front page.
To add description to a category, go to Dashboard > Posts > Categories. Select a category in the table to the wright or create a new category. Type the description in the text field Description, Weather or not this description will be viewed for visitors on the site is up to each theme. The Easy WP Meta Description plugin will add the description as meta information in the html head.
Descriptions for tag and custom taxonomies are edited in similar fashion.
To edit a front page description you would go to Dashboard > Settings > General and edit Front page meta description. 
If you use a static page as Front page the static page Meta description will be used and Front page meta description at general setting will now show.
This plugin relies on the wp_head() action hook. It will only work if the theme uses it. Most themes do.
When deleted uninstall script runs which deletes all changes in the database perfomed by the plugin. 
If you dont want to delete your descriptions and other settings only deactivate and dont delete.
