I don't blame people for going for the easy money, but it's like paying "writers" to write thousands of articles about "best pool equipment 2021" to target keywords on Google just so you can soak up Amazon affiliate revenue. Sure you make money, but how many people are reading your "blog" as fact?
Yeah, the review sites that drive affiliate revenue with content marketing SEO tend to hire low cost writers to do web searches and write articles, stopping just short of the plagiarism line, realizing that duplicate content isn’t good for SEO.
These sites aren’t going to to really test the pool cleaning equipment, the web hosting services being reviewed and ranked, learning Python tutorials. Nobody is going to pay anyone to test anything to make sure how the how-to cobbled together from three similar articles actually works.
