I have content hurricane - it does not shorten the article, it adds strange characters to the article and depending on how much you choose % wise, it will get through copyscape. The problem I see with it is, Google dont like those characters, therefore, google dont have a clue what your article is about, therefore you are not getting indexed.......
1. View 'the article in the search engine's eyes' This is what the SE spiders see. The SE's have no idea about the original article, all they know is what they can see. What they will see is a bunch of words from your original article, so the words will all be on-topic, and the content will be unique. Admittedly the grammar will be non-existent, but SE spiders don't care about grammar.
2. If there are words that you definitely DON'T want Content Hurricane to 'mess' with - like your main keywords - you can enter them in the protection list so that they are left in tact for the SE spiders to see.
3. CH does not add strange characters, the converted article should look exactly the same as the original article - if it does not, contact support.
