This is one of my favorite paid plugins here at Oxwall, and it's a fairly simple one -- but very effective. Easily edit page titles, add keywords, and improve your SEO. I have this running alongside SimpleSEO and deactivated the admin console item SPSEO adds in favor of SEO Text, as you can edit more using this plugin. Had initial problems with being the first purchaser, but the developer was insanely quick to respond and had actually messaged me first about the plugin. Props to him, and thanks for the plugin!
