The click

I built this on a Katana Kult ad because it sells a product purely through the moment it works. It has been live since 15 October 2024, and the brand runs about 26 active ads on Meta, many of them cuts of this same format, from 9 to 41 seconds. My read: you don't keep re-cutting one format for almost two years unless it pays for itself.

AUTODOC's problem is the reverse of a keychain's. Nobody wants a cabin filter, but every driver wants the job done right first time, and the click is the moment that shows it. It also solves the hardest copy problem. We can't promise fit (AUTODOC's own reviews include wrong-part complaints), but we can show a part snapping home on the car it was ordered for. AUTODOC's own gloved macro hack ("Spray Can Seal Fix") has 4.4m plays on TikTok, so people do watch this kind of footage from the brand. Yet in the AUTODOC videos I checked, the app never shows up.

I went with Meta because that's where UK men 30+ are. Facebook's UK ad reach is 38.8m people, 47% of them men, while TikTok's UK ad audience is 62% women. A no-talk montage with labels also suits a feed where lots of people scroll with the sound off.

Almost half the cars on UK roads are over ten years old (SMMT), so they're long out of warranty and every repair is paid out of pocket. Their owners know small jobs are cheaper done at home. What they don't believe is that the jobs are small. Four parts clicking home, each with an honest timer, fixes that in 18 seconds.

The other doubt is ordering the wrong part, and the app answers it on screen: his reg, and only his car's parts. Two cars, a Ford Focus and a Vauxhall Corsa, both among the UK's four most common, do what Katana Kult's rack of 50+ designs does: the viewer looks for his own.

All recorded on his own phone, personal data blurred in the edit:

1. His reg going in for each car, with the car shown in the header, plus the item count if the app shows one (AUTODOC's App Store screenshots show "Items available for AUDI A4 Allroad: 31405").
2. The parts list for each car.
3. The tutorial for each job, 3–5 seconds each.
4. The basket and its total, and the order confirmation.
5. The same items on autodoc.co.uk, the same day, with the clock visible. AUTODOC makes this claim itself ("Buying via the app is always cheaper than on the website", UK help centre), but we only show his screenshots.

App link

apps.apple.com/gb/app/…/id1014949597. The link in the task brief (id1081500282) returns a 404 in every store I tried, so I'd confirm the right link with the client

• Launch: 3 hooks × 2 creators with different cars = 6 ads, one app campaign, UK men 30+, broad targeting.
• Read in this order: thumb-stop (3-second views ÷ impressions) picks the hook. The 50% and 95% completion marks show whether the 1/4 → 4/4 counter holds people; if they drop at the app screens, I shorten them. Then CTR, CPI, and CPA on first purchase, which decides what scales.
• Round two: one spoken line ("Put my reg in, it only shows parts for my car") against silence; £ instead of minutes on the labels; a wipers-and-bulbs winter pack; and the garage-quote story as a full UGC talking-head version, as a pure angle test.
