I bought this plugin when it was first released. I think at the time it a WSO.
However it was full of gliches. The owner then released another couple of updates which improved it but was far from perfect.
In the end he got so tired of my support requests he gave mea refund but let me keep the product.
Since then it has become progressively worse in providing inaccurarate reports.
For example: It will give you a low score because your keyword is not in the last sentence or you don't have the keyword in a H1 heading when you clearly do.
Recently when I updated to WP-3.1.1, I started getting the triangular question mark problem throughout my updated posts but on deactivating the plug in, they vanished.
Here's an example from one of my posts:
�s many virtues.� That is, those sites and blogs displaying Pattaya guides which have not been closed down or blocked by democratic governments exercising their right to keep �unhealthy� information and personal opinions hidden from the masses �for their own protection�.�
Like so many other problems with wordpress, it was caused by a plugin which is why people should try systematically deactivation plugins before they go running off to forums for help.
