We need to find a metric for anti-profitability. I think that index could yield much higher quality results.

Detect sales/commercial language and structure,* and specifically target that for removal from results as if sales-oriented sites were hardcore porn and the child safety filter is turned on.

*Buy and cart buttons/functions, tables containing prices with descriptions but don't look like long-form reviews (which would be it's own filterable tag), etc, and domains trying to obfuscate are blacklisted permanently.

Really just removing all sites with ads would be a huge improvement. Regular old websites trying to sell you something are usually not nearly as bad as those that want to monetize you while pretending to be free.
