Been hearing a lot about cookies going away and I’m worried about my campaigns. Does switching to cookieless tracking actually hold up in real tests or do you lose a ton of conversions?
Yes—if you implement cookieless the right way (server-side + first-party identifiers), you can keep conversion loss to low single digits; when people “switch” by relying on JS-only click IDs or weak fingerprinting, I’ve seen 10–30% attribution leakage on Safari/FB in real traffic.
Best-performing setup is: 1st-party tracking domain + server-to-server postback (S2S) with a persisted click_id (URL param stored in 1P cookie/localStorage) + CAPI/Enhanced Conversions where possible; test it with an A/B holdout (cookie vs cookieless) and compare attributed CVR/CPA + match-rate metrics in Voluum/RedTrack/Keitaro before fully migrating.
Cookieless tracking can hold up well if it’s server-side (postback/S2S) with solid attribution rules. In my tests, when offers use first-party data + CAPI/S2S, losses are usually minimal; the big drops happen with “cookieless” setups that still rely on shaky browser fingerprinting. Ask the network if they support S2S, fallback tracking, and deduping. BizzOffers has several biz offers already optimized for this.
Server-to-server (S2S) tracking is actually more reliable than cookies because it bypasses browser restrictions and ad-blockers. You won’t lose conversions; you’ll likely gain accuracy and future-proof your campaigns against upcoming privacy updates.
