Or sites that are just SEO/GPT spam made for ad revenue. Say I want to know if a side effect my pet is experiencing is normal for a medicine the vet gave them. I search DuckDuckGo for "cat {medicine} side effects", and half the results are pages where you have headlines like:

    What is a(n) {issue}? (what you went to the vet for)
    Should you worry about {issue}?
    What to do if you see {issue}
    Is {medicine} safe for your cat?
    Is {medicine} appropriate for {issue}?
    ...and more

Only after a half dozen or so stupid sections (with ads littered between them) do you get to the actual list: "What are the side effects of {medicine}?" Why don't search engines have a way to report spam sites?
