Meta is always zero

"Char count=0, Word count=0, Keyword count=0, Keyword density=0.0, Keyword prominence=0.0"

Is what i have with all the nodes, which is logical as nothing is imputed. But i use default settings for title, keywords and description in meta tags, they are all auto generated. It would be good if this module could get data from rendered node than and analyise it. Then again this metas are low on importance in SERP and if this is hard to do then maybe you can just ignore it :-)
