One drawback in Search Engine Optimization for the old versions of WordPress was the way the Meta information was laid out. This plugin inserts our meta information appropriately for the home page, but then also allows us to set specific meta titles, descriptions and tags for every post and page we publish.
All we need to do now is fill in our information in the three highlighted boxes. If you follow an SEO Guru (I'm not one), by all means take their advice here. Just get the best meta information here that you can.
