Just because a product or service is profitable it doesn't mean it's a good product or it's not a scam, and in the case of Google results the companies can make the honest reviews of the product rank lower or basically hide them in the second page of results with their paid ads, which is making it harder for the consumers to figure out the real quality of the product before buying. Of course not every organic result is honest but ads can make it worse.
