I work with the guy who asked the original question. The issue is more nuanced then originally framed, but did represent one line of our thinking. In practice we have been writing a blog post and then rewriting them as best we can from the perspective of another writer. Our thinking is, within a large franchise a certain % of these will employ content marketing, and a certain % will logically come up with the same blog topics. The answers given to these topics will largely be the same e.g., "How much longer does synthetic oil last compared to conventional oil?" The answer will be the same, the writing will be different.
Assuming we do a good job on the rewrites, does anyone see why this wouldn't work? Can someone suggest a good way to test whether this is working i.e., Google respects these rewrites and gives them a chance to rank?
Thanks.
