One thing I’d recommend for beginners is to understand the difference between a click and an attributed conversion. A referral cookie may last for a certain period, but another referral source or a later interaction can sometimes change which source receives credit.
I’d also keep the tracking setup consistent across links and check the reporting regularly instead of assuming every sale will be attributed automatically. Even something as simple as comparing how different sites handle referrals for something like auto insurance quotes bedford can show why clear tracking rules matter.
