A few things worth knowing
Is simulated ad testing a replacement for live ad testing?
No. Cairo produces simulated signals that help you compare creative directions and prioritize what to run with real budgets. Live platform data remains the way to confirm performance.
Cairo Labs·MethodCan I test ads I haven't designed yet?
Yes. Describe the campaign, the hook and the offer—or paste the landing page the ad points to. Cairo simulates reactions to the concept before production.
Cairo Labs·SetupDoes Cairo test the ad and the landing page together?
Yes. Simulated clickers continue from the ad onto your page, so you can see where the promise breaks between the creative and the destination.
Cairo Labs·JourneysHow much does ad testing with Cairo cost?
Free includes 500 welcome credits. Pro includes 10,000 credits for $29 per month; Agency includes 50,000 for $99 per month. Costs depend on the pages, interactions and variations involved. Failed actions are refunded.
