Can anyone recommend a good keyword density checker
Not not just something that tells you the occurrence of individual words as a % (such as Keyword Density Checker - Keyword Cloud)
But something that can give you a breakdown of phrases 2 word / 3 word phrases like what Latent Semantic Indexing does for their results.
PS I know that following a rigidly structured keyword density pattern is bad on-page SEO in today's world.
I want to use these tools to make sure I'm not unknowingly keyword stuffing by accident.
