Test the ad and the landing page together. Before you pay.
The ad earns the click. The page has three seconds to keep it. Ad Campaign Simulation runs the full funnel before launch, so you catch the break before you pay for traffic.
How it works.
Two stages, modeled apart: the click decision, then the conversion.
Read the ad
Each role decides, as a skeptic. Click or ignore.
Check the scent
Clickers carry the promise to the hero. Does it hold?
Scroll and decide
Every friction logged. Convert or abandon, with a cause.
Compare creatives
Projected CTR, CVR, wasted spend. Before you pay.
Three ways it fails. Three fixes.
Each one is invisible until after launch. WhyUser catches all three before the spend.
The scent-trail break
Ad says “30% lower TCO.” Hero says “The Modern Data Platform.” Gone in three seconds.
Optimized for the clicker
A page built for the engineer loses the CFO and security, who review it next.
Blame, no attribution
Ad, audience, or page? Analytics cannot separate the click from the conversion.
The Kill Sheet, and everything around it.
Weeks of live A/B testing. Replaced by one run, before spend.
“30% lower TCO”
“The Modern Data Platform”
