How about image autoblogs? does it get penalized for unique content?
I mean if I edit the image with PHP (like add a watermark, so that the checksum of the image file is different), will google take pains to match the image with loads of others to see if the image is unique, or simple assume it's unique and take my blog as a genuine blog?
I'm thinking of making such a autoblog script...what are your views?
Do yourself a favor and use a bit more time writing your own content instead of using Autoblogging software (like WP Robot) - it's not worth it. Google adjust it's algorithm all the time, trying to move those sites away from the top results.
Instead focus on one or two sites and write a couple of posts to each every week. You dont need to write 10 per day, just a few every week to keep it active.
if you can make it look like an authority blog rather than a simple autoblog , than you've hit a goldmine , think outside of the box !
Google is too smart.
