admin_auto_seo_field

With this extension you can forget the 'Seo Keyword ' field on the admin page.
This extension automatically generates a Seo Word based on product name + the product model.
If for some reason there is a change in the model name or reference, it will be also updated automatically in the Seo field.

The next explanation it's for advance users, and it's optional, that's means that doesn't interfere in the normal work of this extension.

The Seo Keyword field, is particularly important to those that use the Seo name to help the google and others to find your products.
To use SEO URL's apache module mod-rewrite must be installed and you need to rename the htaccess.txt to .htaccess. 
To do this, go to System > Settings > Edit > Server and activate the "Use SEO URL's". Then with a file editor, like filezilla, enter on your server and rename htaccess.txt to .htaccess.
