Reels-first ad scripts that convert

Quick Answer

A Reels-first ad script is not a square ad reformatted to 9:16. It is written from the ground up for vertical viewing, sound-on default and a feed where every second is fighting against creator content. Reels-first means three things: face in the frame within the first second, audio that earns the unmute, and a CTA that does not look like an ad.

The full script (scene by scene)

Product: A skincare serum.

Scene 1 (0.0s to 1.0s) Face hook

• Visual: Creator pops into frame from the top, hand still tucking hair back. Phone is held vertically, no studio lighting.


• Audio: "Tell me why nobody warned me about this."

Scene 2 (1.0s to 3.0s) Pivot to product

• Visual: Creator turns the camera to a bathroom shelf, points at one bottle.


• Audio: "I have been using this every night for six weeks and my skin texture is gone."

Scene 3 (3.0s to 6.0s) Demonstration

• Visual: Close up. A drop of serum on a fingertip, creator presses it into the back of her hand. Skin absorbs it instantly.


• Audio: "It is one ingredient, retinal not retinol, and it actually penetrates."

Scene 4 (6.0s to 9.0s) Before/after

• Visual: Two-up phone screen. Skin texture before, skin texture now.


• Audio: "These were taken eight weeks apart. I did not edit anything."

Scene 5 (9.0s to 12.0s) Comparison

• Visual: Creator picks up two competitor bottles and drops them in a bin.


• Audio: "I cancelled my other two routines last week. I do not need them."

Scene 6 (12.0s to 15.0s) Soft offer

• Visual: Creator holds the bottle to camera. On-screen text: "Linked in bio. Code MORNING for 15 percent."


• Audio: "It is linked below. Code MORNING gets you 15 percent off."

Why it works

Notice the script never uses 'introducing', 'we are excited' or any other ad language. The first line sounds like the start of a personal post, not a campaign. This is the unwritten rule of Reels-first: the ad has to sound like content the viewer already follows.

The pivot in scene two is the second most important moment. You have one second to move from the personal hook to the product without it feeling like a switch. The trick is using a sentence that mentions the product casually instead of selling it.

Common mistakes

• Filming horizontally and cropping. The aspect ratio is half the format.
• Adding a music track louder than the voice. The voice is the unmute trigger.
• Overlaying brand-coloured borders or logos. They scream 'paid'.
• Closing on a 'shop now' button instead of a 'link in bio' line. Reels viewers respond to the second one.
• Casting a model. Casting a real user always wins on Reels.

FAQs

Should Reels-first ads have captions?
Yes, but small and bottom-third. Captions on Reels are reading-only, not stop-the-scroll material.

How long should a Reels-first ad be?
12 to 22 seconds is the sweet spot. Anything longer needs a stronger creator and a real story arc.

Can I run the same ad on Reels and Feed?
You can, but Reels-first never wins on Feed. Build it for one and reformat downward, not the other way around.

Do trending sounds matter for ads?
Less than they do for organic, but a familiar audio still lifts hold rate by 8 to 12 percent in our tests.

Should I run Reels through Advantage Plus or manual placements?
Manual until you have three winning Reels creatives. Then turn on Advantage Plus and let it find more.
