|Your statment is a perfect example of why we're seeing Google taking action against EMDs. SEOs have been doing exactly what you say on a huge scale for years. Why would Google want to rank thousands of sites, millions of pages of stuff generated by the SEO industry? |
If every SEO that setup a site on an EMD built the best possible site for that niche, then I doubt we'd be seeing this update. But the reality is that a lot of EMD sites target low hanging fruit with boilerplate sites that have little to no resources behind them. There are lots of exceptions of course, as realmaverick points out, but I don't recall a Google update in the past decade that hasn't taken out innocent bystanders. Nature of the beast.
