I always wanted to see just a "price transparency" aspect.

Tell me exactly how much the advertiser paid for his placement, and that's a hugely important signal here.

If I'm searching for weird hobby parts, even though it's a high purchase intent query, they're probably paying pennies per click.

But if you start searching, say, financial stuff and the ad placement figures start showing multiple dollars per click, it's a warning "these people are willing to spend THIS MUCH MONEY to present a message to you, this probably means there's something sketchy involved."

I know, for example, anything pertaining to insurance and financial products is highly likely to turn into a farm of cross-selling and personal-information harvesting, because the cost per acquisition is so high and the tendency for everyone to sell the information to everyone else is so great.
