How to Create AI UGC Ads, Step by Step

By Atharv Sankpal

This is the workflow I use to create AI UGC ads for ecommerce brands, in the order I actually do it. If you follow it you will end up with a set of testable ads instead of one pretty clip. New to the format? Start with what AI UGC ads are, then come back.

Step 1: pick one angle, not five

An angle is the single reason this buyer should care: saves time, ends a specific irritation, replaces something expensive, works when the cheap version failed. Read your own reviews and support inbox and steal the sentences customers already use. One ad, one angle. Ads that try to say everything say nothing.

Step 2: write ten hooks for that angle

Ten, not one, because you cannot predict the winner and the hook decides the ad. Keep each under about twelve words, make it specific, and make sure the opening frame supports it. I keep a running swipe file, and there are fifty starting points in 50 video ad hooks that stop the scroll.

Step 3: write a script that sounds spoken

Hook, 0 to 3 seconds: the line plus a frame that earns attention.
Context, 3 to 8 seconds: who you are and why you tried it.
Proof, 8 to 20 seconds: what changed, shown rather than claimed.
Objection, 20 to 28 seconds: the doubt they already have, handled in one line.
Call to action, last few seconds: one action, said plainly.

Read it out loud. If you would not say it to a friend, rewrite it. Contractions, short sentences, one idea per line. Sixty to a hundred and fifty words is the working range for a 15 to 45 second ad.

Step 4: generate the actor

Pick an actor who plausibly buys your product, not the most attractive face in the library. Match the setting to the claim. Generate the same script with two or three different actors, because delivery changes performance more than people expect. Tools that do this well right now include Arcads, HeyGen, Creatify and MakeUGC; I compared the two biggest in HeyGen vs Arcads.

Step 5: edit it into an actual ad

Cut the first half second. Almost every generated clip starts slightly late.
Add burned-in captions. Most of the feed is watched muted.
Cut to the real product every few seconds so the ad is grounded in something physical.
Keep it under 30 seconds unless the story genuinely needs longer.
Export vertical 9:16, and a 4:5 version for feed placements.

Step 6: test properly

Keep the body identical, swap only the first three seconds, and run the variants together. Judge hooks on hook rate, judge the survivors on cost per result, and give each one enough impressions to mean something before you kill it. Then refresh hooks on winners rather than rebuilding from scratch, which is the cheapest fix for creative fatigue.

How long does one AI UGC ad take?

Once the angle and script exist, a finished ad is usually an hour or two of work. The thinking takes longer than the rendering, which is the whole point: the tool removed the cheap part of the job, not the hard part.

Common mistakes

Generating before writing. The tool cannot save a script with no angle.
One hook, one ad, no test. You learn nothing and blame the tool.
Brand voice in a UGC ad. It instantly reads as an advert.
No product footage at all, so nothing on screen proves the product exists.

If you would rather hand this off, I make AI UGC ads, plus Facebook ad creative and TikTok ads, as a freelance AI ads creator.

Want the ads made for you?

I make AI video ads for ecommerce brands end to end: the angle, the hook, the script, the actor and the edit. Not a tool to learn, a person who ships creative you can run.
