How avoid "thin affiliate" penalty?
A website of mine uses WP-Robot to pull articles from Amazon. However, this way I have lots of duplicate content on my website.
So, unless I act upon I fear Seach Engines (staff) could mark my site as "thin affilate", and thus the site woud become worthless.
I am adding a couple of unique articles about the product niche to add some more value for visitors, but the post aren't affected by this.
What is a smart way to make product posts more unique (manual, partial rewrite takes too long) ?
