Google and defamation / falsification of information websites question.

Curious, if someone is the one who knows. For approximately fifteen years, Google has delivered excellent results on page 1 of many of the great defamation / extortion (complaints) websites. In the age of false news, does anyone know why they continue to do this? Thousands of pages on these sites are false and erroneous reports, but still get excellent results on the first page. Will this continue indefinitely?
