Do you want to catch more visitors for your ads, adultfriendfinder or backlinks? - it can be useful to fill your website with good content.
If you copy text from other websites to place it on yours, google will immediately notice!
Of course google indexes all websites with a date and the website with the much lower date is in the most cases the writer of the text.
So you will need to scramble the content first, then place it on your website!
For humans the scrambled text makes completely no sence, but for the google-robot it is good as it was before.
I wrote a java program that takes every word from the original text and places it randomly into a new position.
It has a minumum distance you can choose by yourself.
By using my programm you prevent google to see a connection between the original content and the scambled one.
