TL;DR: Most underperforming ads aren’t bad ideas. They’re good ideas undone by avoidable mistakes: a weak first second, a message aimed at the wrong awareness stage, or a call-to-action hidden behind the platform’s own interface. With creative now driving roughly half of campaign performance, a launch checklist is the cheapest quality control you can run. Here’s the one we use at Toco, including the exact safe zones for Meta’s two most important placements.
Why a Checklist Beats Talent
Every team believes its eye is good enough to catch problems before launch. Almost none are, because the problems aren’t aesthetic. They’re functional, and they hide in plain sight. A beautiful ad with the logo buried under the caption bar, or a clever hook that takes three seconds to land, will fail just as hard as an ugly one. The checklist exists to catch the functional failures the eye glosses over.
Run every creative through these ten checks before a single pound of budget reaches it. None takes more than a minute. Together they catch the mistakes that account for most wasted spend.
1. The Hook Passes the Two-Second Test
Show the ad to someone who’s never seen it, give them two seconds, and ask what it’s about. If they can’t answer, the hook is too weak. On a real feed you get about 1.5 seconds before the thumb moves, so two seconds in a calm room is a generous test. For video, the first frame and the first spoken line both have to earn the next moment, so don’t open on a logo or a slow pan.
2. The Message Matches the Awareness Stage
An ad built for someone who’s never heard of you should feel slightly off to someone who abandoned their cart yesterday, and the reverse is true too. Top-of-funnel creative names a problem and earns attention. Mid-funnel creative provides proof. Bottom-of-funnel creative removes the last objection and makes the next step effortless. If your ad would make sense at all three stages, it’s too generic to win at any of them.
3. The “So What?” Is Obvious
Read the core message aloud and ask, genuinely, “so what?” “We use AI-powered targeting” fails, because it’s a feature with no stakes. “We cut customer acquisition cost by 30% in 90 days” passes, because the benefit is concrete and the reader feels it. Every ad needs one clear, liftable benefit rather than a list of features.
4. There Is Exactly One Call to Action
One ad, one job, one action. The moment you ask for two things, like “shop now and follow us and download the guide,” you’ve halved the odds of either. Decide the single next step and remove everything that competes with it.
5. It Respects the Safe Zones
This is the check teams skip most and regret most. Every placement has regions where the platform’s own interface (captions, profile pictures, action buttons, progress bars) sits on top of your creative. Put anything important there and it’s gone. Here are the two placements that matter most.
4:5 feed (1080 × 1350px). In feed, a 4:5 image can be cropped toward the central square. Keep logos, text, and product hero inside the central area, and treat the top 10% (about 135px) and bottom 10% (about 135px) as overflow that may be trimmed. Nothing critical lives in those bands.
9:16 Stories and Reels (1080 × 1920px). This placement is heavily overlaid by UI. Keep critical content clear of:
- the top ~12% (about 230px), where the profile picture, username, and progress bars sit;
- the bottom ~25% (about 480px), which holds the caption, username, hashtags, and the sound ticker;
- the right-hand ~12% rail, where the like, comment, share, and save buttons live;
- the very bottom bar (~7%), used for the reply input or CTA button.
The practical rule: design the message into the central vertical band and let the edges be atmosphere. Don’t eyeball it. Drop the file into our Safe Zone Checker, pick the placement, and see exactly what the UI will cover before you publish.
6. It’s Legible With the Sound Off
Most of the feed plays muted. If your video relies on a voiceover to make sense, caption it, using open captions burned into the file rather than the platform’s auto-captions, which may not show. The hook especially must land in silence.
7. Branding Appears Early Without Leading
Your brand should be recognisable within the first few seconds, not saved for a logo reveal at the end that nobody reaches. The balance is to keep brand presence early enough to register, but never as the opening that gets scrolled past. A product in use beats a logo on a card.
8. Text Density Is Under Control
Walls of text don’t get read in a feed. Lead with one idea per frame. If a static needs a paragraph to work, it’s really a landing page wearing an ad’s clothes. Cut to the single most important line and let the rest live after the click.
9. The Format Earns Its Place
Is this the right format for the job and the funnel stage, or just the format your team defaults to making? A testimonial wants a real face and a low-fi feel; an offer wants a clean static; a demo wants produced video. If every ad in the account is the same format, that’s a monotony problem, and we cover the fix in our guide on creative diversity.
10. It’s Part of a Batch, Not a One-Off
No single ad should launch alone. It should arrive as part of a diverse batch sized to your budget, with variations ready to test against it and replacements queued for when it fatigues, a moment you can predict with the Creative Fatigue Score. A lone ad has nothing to be measured against and nothing to hand off to. If you’re not sure how many should be in the batch, our creative volume guide does the maths, and the Creative Volume Calculator sizes it in seconds.
Where to Start Tomorrow
Turn these ten points into a shared document and make passing them a non-negotiable gate before anything goes live. The discipline feels slow for the first week and then becomes invisible, and your launch quality rises immediately, because the cheap mistakes simply stop reaching spend. The checklist catches execution mistakes; to get the strategy right upstream, pair it with our guide to writing a creative brief that gets made.
Creative quality control has little to do with having the best taste in the room. It comes down to never letting a good idea die from an avoidable, fixable mistake, and the checklist is how you guarantee that.
