I just wanted to talk to those that have gotten the premium theme and the newest SEO plugin along with that. This is probably the most complete and versatile seo plugin I have seen. It does not have anything to do with adding your meta tags, the theme will do that itself.
There are a few features I wanted to mention like how it calculates the kekyword density.
1. (Total Keywords / Total Words) * 100
This is the most common formula used in other plugins (uses this formula by default).
2. (Total Keywords / (Total Words / Total Words in Keyword Phrase)) * 100
This keyword density formula is more accurate for keyword phrases because it takes into account how many words are in the phrase.
Now along with that, is the fact that it does much more when calculating the keyword density because it does not just look at what is on the post creation page. It actually uses a "get" request to pull the xhtml and looks at the entire page. Just making this one little adjustment helped my new site tremendously. I will not say how much because your results may vary.
The plugin has the ability to check the xhtml while saving in draft mode.
Another cool thing is the LSI keywords, The related links, calculation of secondary keywords, bulk uploading of your keyword list, drag and drop images and much more. The one really cool thing that I liked was the api interface for CopyScape. Yes it will check copyscape for you also using your account and api.
This one is a replacement for SEO Pressor. If you have any questions about the features of the plugin let me know. I have it set for option #2 for the density calculation.
Special note to those that may be thinking about getting this, your host must allow the get requests. Hostgator by default has that turned off so you need to get them to turn it on for that domain.
Forgot to mention that all the help and tutorials built into the plugin are videos.... How is that for cool. Helps a Noob that does not know anything about the issue figure it out.
