For many search terms, the entire above-the-fold and sometimes multiple scroll heights are filled with:
- Ads
- Info cards
- People Also Ask
- Map/Business info
- Videos
- Related Products
- More Ads
The organic search results start after that and on mobile they may as well not exist.
If everyone is clicking the directly or indirectly sponsored/algorithmic content then what incentive does Google have to give you good, straightforward links to relevant webpages?
