Editorializing: Paid clicks on Google properties +43% - "yaaay we're driving more paid search!" Cost-per-click on Google properties -16% - "ouch our advertisers are seeing less value on these add'l clicks!" To me the second part of this is going to be most interesting to watch - if the clicks they are onboarding are lower quality, this is going to be a net negative.
I have felt like the easy pickings have been behind them for a while but given enough money you can buy a lot of traffic. Not great traffic mind you but a lot of it.
