The reason I'm asking this is because I've heard that Google is proclaiming "war" against EMDs. I don't have any iron proof for this, so don't freak out.
The way I build my Amazon sites is by selecting an EMD for a decent term (not something "spammy"). I opt for a decent search count per month (2200+) with a low to medium competition level, and some healthy long tail keywords.
I don't usually go for review sites, I mostly deal with promotion, sales, offers and articles about the products. The way I monetize is by strategically placing a photo and a "See more products" button. So keyword density, multimedia and onpage optimization is not an issue.
My real problem is that if Google gets its nose into EMDs, and makes 'em vanish my whole SEO strategy gets ruined. EMD selection was a crucial part of my whole ranking strategy, this made it easy to rank my sites middle 1st page, top 2nd in a short period of time.
I know there are many other strategies that can be used, but those take longer, some cost a bunch. And my question, is it really worth the hassle for an Amazon commission?
Brainstorm with me guys, I'm really curious if I should continue building these sites or get onto something else for my passive income streams...
