I hear the best way to autoblog is changing the footprint, which I think is rewriting or spinning the content..correct? But how much content should we change? For example if there is 100 articles do I just do some keyword research and optimize 1 article each for lets say 10 keywords (10 articles)? But what about the rest of the pages/content...does it get natural traffic as people go to the optimized articles then start looking around? Or do I just hope to naturally rank 1st page for so many very low search volume keywords that when combined it adds up to decent traffic? I mean what is the purpose of an autoblog if most/a lot of the pages don't get viewed? I might as well just make a smaller microniche site but with all unique content? I guess my question is how much altering of content should I do...and why....if I am altering so much content....what would be the purpose of an autoblog??
