Klaviyo's paid case study makes phone visitors wait behind consent
A current ad sends interested prospects to the Killstar success story. On a phone, the page can take more than 15 seconds to finish showing its main content. Before the proof appears, a large consent panel takes over everything below the headline.
Owner brief
We reviewed five current Klaviyo ads and followed the Killstar promotion to its exact destination. We checked the page on desktop and mobile, tested the first 20 links, and opened the public signup route without entering any details.
The ad and case study tell the same story. That part works. The leak starts after the click: mobile visitors have to wait, then deal with a screen-filling choice before they can read the results they came for.
Highest-priority paid-traffic leaks
1. The consent panel takes the page away just as the proof should begin
On a fresh mobile visit, the Killstar headline appears. Directly beneath it, the consent panel fills the rest of the screen. The case-study image, the 89x result, and the supporting story sit out of view.
That is a poor handoff from paid attention. The visitor clicked to see how Killstar grew. Instead, the first real decision is about cookies. Some will leave before they see the proof or reach signup.
Start by shortening the panel on small screens. Keep the required choices, but reduce the copy, tighten the spacing, and let more of the case study remain visible. Then check the opening screen every time the consent design, promotion bar, navigation, or page template changes.
FunnelWatch should keep watching how much of the first phone screen the panel covers and whether the Killstar result remains visible before a visitor makes a consent choice.
2. The case-study content can take more than 15 seconds to finish appearing on mobile
In our mobile visit, the main visible content finished appearing after 15.6 seconds. The desktop visit took 1.9 seconds. The phone page also stayed busy for long stretches while it loaded the case study and the systems around it.
A prospect coming from the Killstar ad has already shown interest. A delay this large gives that person plenty of time to abandon the page before the 89x result can do its job.
Start with everything that loads before the first case-study result. Delay nonessential page tools. Cut scripts and media that do not help the opening pitch. Test the paid destination on a normal phone connection after each release, not just on a fast office connection.
FunnelWatch should keep timing when the headline, first result, and signup path become usable. It should flag any release that pushes those moments backwards.
What we checked
Funnel depth tested: current public ad to the Killstar case-study page on desktop and mobile, the first 20 links on that page, and the public signup page rendered without interaction.
All 20 checked links responded. The paid campaign details stayed attached to the case-study visit. The public signup page loaded and presented Klaviyo's free-start message.
We did not enter an email, create an account, submit a form, test onboarding, reach billing, attempt payment, or check confirmation and follow-up messages.
Fix this first
Protect the first phone screen. A prospect who clicked for Killstar's results should see those results quickly, with the consent choice taking as little space as the rules allow.
Keep the paid route intact
This leak can return when the ad destination, consent panel, tracking, navigation, media, or case-study template changes. FunnelWatch can keep following the same route and catch the release that hides the proof or slows it down.
