Don't know if this is the reason OP hates it, but for me SEMRush and similar companies are the reason the web is littered with blogspam for pretty much every topic.

Content Marketing companies and Content Farms use SEMRush to figure out which topics are covered by competition of their clients and which topics would attract visitors, and then pay pennies to a non-expert freelancer to produce a very shallow text with content probably copied from the same competitor, and littered with keywords recommended by SEMRush. Then, this text rises to the top of Google while non-SEO optimized quality content lingers in obscurity.

How Google doesn't go after those shady practices is beyond me. They're probably just afraid of killing a whole industry and having an antitrust target on their backs.
