I wonder if there'd be any value in a search engine that recognized popular third-party ad networks and simply did not add to its index any page which includes them. (Or, at least, provided users an option to filter those results out.)

How would a search engine that doesn't have pretty much any major publication and a lot of content-driven websites gain any traction at all? There is so much it couldn't find, and while you may be fine with that, I doubt many people would be.

It's a constant high stakes cat and mouse game though. A good idea for sure but the ad networks will expend incredible effort to avoid the filters
