I found another plugin i thought was good, seoboss but it includes a tag that Google does not use.
EFSEO is the best because it allows you to create a new meta title and it replaces the tag. It also saves the meta title, description and keywords into the database with the article so if you delete the plugin the information is left there. You don't have to redo the work!
I love this plugin also because it is front end. I just got to one of my pages, figure out which keyword to target and enter the information in. No need to find article in backend and open it.
Nice! Thank you very much for your review.
I wish you success with EFSEO!
