At one time I had about 10 sites about 7 years ago, I decided to follow google suggestions and combined them into 2 large sites. The original 10sites all ranked well and after I combined them
they ranked even better. The last penguin update the 2 sites got hit, so I uncombined them back to 10 sites and the 8 sites when back to ranking well and the 2 main domains just came back to their old rank before the update.
It seems google like shallow light content sites.
I am back to my old ways thanks to google. I will now create another 10 sites. Google is broken.
