The quick version:
Browser privacy changes and tighter rules have made old cookie tracking unreliable, and programs are losing data they used to count on.
Server-side tracking survives where cookies fail, but you will need a developer to set it up.
First-party data and contextual targeting are the durable backups.
Move tracking to the server
Instead of relying on the browser to carry data to the affiliate network, data flows server to server, which holds up even when a browser blocks the cookie. It takes more effort, but it is the difference between measuring your real impact and guessing.
Collect data you actually own
Ask people for their details through subscriptions and surveys, and you hold information nobody can block. Then lean back into context, targeting based on what someone is reading right now rather than what they did last week.
Attribution is harder, not dead
I have seen people on X claim attribution is finished and there is no point measuring anything. That is lazy. Cohort analysis, grouping buyers by shared traits and watching the group, gives a cleaner read than chasing every click. The affiliates who invest in this now will be the ones who can prove their value when a brand reviews its budget.
