Google has turned into a cesspool. Half the time I find myself having to do ridiculous search contortions to get somewhat useful results - appending site: .edu or .gov to search strings, searching by time periods to eliminate new "articles" that have been SEOed to the hilt, or taking out yelp and other chronic abusers that hijack local business results.
Those fake shops are part of discussions in politics right now. Usually they're registered in Ireland or Malta as companies due to their specific banking laws. They make millions with those scams and people can't differ between legit online shops and fake ones - because the legit ones actually look crappier than the fake ones when it comes to the website designs.
In Germany, we have at least for hardware the "geizhals" website which is kind of an index for all kinds of electronics shops and they try to verify as much as possible.
But for other online shop sectors (e.g. clothing or home stuff) I wouldn't trust anything. Even on Amazon I got scammed a lot and heard absurd things from others...like getting packages with no content in them and Amazon refusing to see that the seller is a scammer etc.
