Why paid search costs doubled for casino affiliates this year
Brand bidding restrictions and a thinner supply of compliant placements have reset the economics of paid acquisition.
Cost per click on casino terms has roughly doubled across UK and Irish campaigns in the last twelve months. The cause is not a single auction change but a compounding of three: tighter brand bidding enforcement, fewer compliant placements, and operators moving budget from affiliates into their own paid accounts.
## Brand bidding enforcement
Most affiliate programmes have always prohibited bidding on operator brand terms. What changed is enforcement. Automated monitoring now catches in days what used to take a quarter, and terminations have followed.
## Supply, not demand
The placements that remain compliant are a smaller pool than they were, and the same money is chasing them. That is a supply problem dressed up as a demand problem, and it does not resolve by bidding harder.
## What the better operators are doing
The affiliates holding margin are the ones who stopped treating paid search as an acquisition channel and started treating it as a defensive one — protecting positions they already rank for organically rather than buying traffic they never owned.
