I of late think there is a market for an anti SEO search engine. Basically hides anything with ads and google analytics.
> The search engine, which brands itself as “more of a discovery engine,” allows users to filter the top million websites on the internet out of their search, resulting in a unique set of results and placing an emphasis on content discovery. This approach to search is also designed to combat the impact that aggressive black and grey hat SEO practices have on mainstream search results.[0]
If the owners are around : would you consider adding nojs support? I know it's an edge case request, sorry to be that guy. But then again, "search without top results" is not exactly a concept that will bring you the average web user :)
I'm not sure if there's a real solution though, pretty much every mechanism for solving this has far too many incentives to break it, so that you'd get traffic/clicks/purchases. Just too much money causes the metrics to be gamed.
