0:00 Social and ad copy with AI
Here's something that surprises people. The best use of AI for ads isn't writing the perfect ad. It's writing ten genuinely different ads, so that your audience can tell you which one is best. Social posts and ad copy are short, high volume and highly testable, which makes them a natural fit for AI. But used lazily, AI gives you twenty versions of transform your life, join us today. In this lecture you'll learn how to feed AI an insight and an offer, get variety across distinct angles, respect platform specs and policies, and set up a simple test. You'll see two examples and watch me build a test set.
0:48 Why variety wins
Why is variety the goal? Because nobody, not you, not your client, not the AI, can reliably predict which message will win. Teams waste hours debating two headlines in a meeting. A small, well structured test settles it with real behavior. But a test only teaches you something if the options are genuinely different. Testing save twenty percent against save a fifth tells you almost nothing. Testing a pain angle against a social proof angle tells you what your audience actually cares about, and that insight improves everything you make next.
1:28 The recipe: insight, offer, rules
Here's the recipe. Three ingredients. An insight, ideally a verbatim customer quote from your research, like I'm not flexible enough for yoga. An offer, exact: the price, the dates, the terms. And the rules: the platform and format, character limits, no claims beyond the product sheet, and required disclosures. Then the method: give me ten variations across five angles, problem, desire, social proof, curiosity and objection handling, two per angle, and label each angle. Add your style rules, like no emojis in the first five words and no exclamation marks. Run it inside your brand project, so the voice guide and approved claims are already there.
2:14 Hooks decide everything
For short video and social posts, the first line decides whether anyone reads or watches the rest. So ask for hooks separately from the body. Write fifteen opening lines, under ten words each, specific, with numbers, places or situations, and no cliches like did you know or game changer. Tag each one: curiosity, contrarian, pain, result or story. Specific beats clever almost every time. Can't touch your toes, good, that's where we start, beats unlock your inner flexibility. Pick three hooks you believe in, and build the rest of the post around them.
2:54 Ad specs and policies
Ads come with rules. Every platform has specifications, like Google's responsive search ads, which use headlines of up to thirty characters and descriptions of up to ninety. Specs change, so check the current ones. And every platform has policies that restrict or prohibit certain claims: health, finance, before and after, guaranteed results, and unprovable superlatives like best or number one. Ask the AI for a table with a character count column, and then verify the counts yourself, because models can miscount. And check every claim against your approved product facts before anything goes live.
3:35 Example 1: the yoga studio
A simple example. A yoga studio in Leicester asks for an Instagram ad. The lazy prompt gives: transform your body and mind, join us today, with three exclamation marks. Instead, the marketer uses the insight from reviews, I'm not flexible enough for yoga, and asks for variations across angles. She keeps four. Pain: can't touch your toes, good, that's where we start. Social proof: a real member's quote, used with her permission. Curiosity: what happens in a twenty minute beginner class. And objection: your first session's free, no mat needed. Each fits the platform's limits and includes the offer terms. Now she has a real test.
4:21 Example 2: the sofa launch
Now a business case, with illustrative details. Hana manages social for a furniture brand in Jeddah. Her brand project holds the voice guide, the product sheet and a list of claims the legal team has approved. For a sofa launch, she generates fifteen hooks, picks three, and builds four Meta ad variations. One draft says the most durable sofa in Saudi Arabia. The facts to verify line flags it, because nobody can prove that. She replaces it with an approved fact: a ten year frame warranty. After a two week test with the same audience and budget for each, the objection angle wins: delivered and assembled the same week. Now she knows what her audience actually worries about, and she briefs the next round around delivery speed.
5:16 Watch me do it
Let me build a test set. Brand: a meal kit company. Insight from reviews: I'm tired of deciding what's for dinner. Offer: forty percent off your first box, new customers, ends Sunday. Platform: Meta primary text, under one hundred and twenty five characters recommended. Rules: no claims beyond the product sheet, no exclamation marks. Ten variations across five angles, two per angle, with the angle labeled and a character count column. Here's the table. Some are great, some are weak. The curiosity ones are vague, so I drop them. I keep four: one pain, one desire, one social proof, which uses a real customer quote we have permission for, and one objection about cancelling anytime. Then I check the counts with a counter, and one is over, so I trim it. Ready to test.
6:14 Run a fair test
A quick word on testing, because a messy test wastes the variety you created. Keep the audience, budget and time period the same across variations. Test only a few variations at a time, so each one gets enough budget to learn something. Decide in advance which metric matters, based on your objective: hook retention for video, click through rate for ads, cost per result for conversions. Then keep a simple log of which angle won, for which audience. Over a few months, that log becomes one of your most valuable marketing assets. For campaign structure, bidding and testing at scale, the AI powered performance marketing course goes much deeper.
7:01 Common mistakes
The common mistakes. Twenty variations of the same idea, so your test teaches you nothing. Ask for distinct angles. Unapproved superlatives and regulated claims slipping through. Keep approved claims in your project and check every draft against them. Trusting AI character counts. And testing too many variations with too little budget, which spreads spend so thin that nothing wins clearly. And don't forget disclosures: sponsored social posts need their paid labels, whoever wrote the caption.
7:34 Recap and try this now
Let's recap. Feed the AI an insight, an exact offer and clear rules. Ask for variety across distinct angles, and generate hooks separately, specific over clever. Respect platform specs and policies, verify character counts yourself, and check every claim against approved facts. Then run a fair test and log the winning angle. Here's your try this now. Take one real offer and one insight from your research. Run the prompt from the lesson text, cut to four variations, check claims and counts, and set up a simple test this week. When it finishes, write down what the winner tells you about your audience.
Where AI helps with social and ads
Social posts and ad copy are short, high-volume and highly testable, which makes them a natural fit for AI. The winning pattern: you supply the insight, the offer and the rules; AI supplies variety; the platform (and your audience) decides what works.
Anatomy of a strong short-form prompt
Brand project: [brand]. Audience: [persona, from research].
Insight: [customer truth, ideally a verbatim quote].
Offer: [exact offer, price, dates, terms].
Platform and format: [Instagram Reel caption / TikTok hook / LinkedIn post / Google Ads RSA / Meta primary text].
Constraints: [character limits], no claims beyond the product sheet, required disclosures [#ad / T&Cs].
Give me 10 variations across 5 angles (problem, desire, social proof, curiosity, objection-handling),
2 per angle. Label the angle for each. No emojis in the first 5 words. No exclamation marks.Hooks: the first line decides
Ask for hooks separately from bodies:
Write 15 opening lines for a short video about [topic] for [audience].
Rules: under 10 words each, specific (numbers, places, situations), no clichés like "Did you know" or "Game changer".
Tag each: curiosity / contrarian / pain / result / story.Then pick three and test them.
Ad copy: variations with guardrails
Ad platforms have strict specifications and policies. Current examples: a Google Ads responsive search ad uses headlines of up to 30 characters and descriptions of up to 90; check each platform's current specs because they change. Policies restrict or prohibit certain claims (health, finance, before/after, "guaranteed" results) and require disclosures in some categories.
Write Google Ads RSA assets for [product] targeting [search intent].
15 headlines (max 30 characters) and 4 descriptions (max 90 characters).
Include the offer in at least 3 headlines. Avoid superlatives we can't prove ("best", "#1").
Return a table with a character count column, then I'll verify the counts myself.Hands-on: build a test set in 20 minutes
- Take one offer and one insight from your research.
- Generate 10 variations across 5 angles with the prompt above.
- Cut to the best 4 (one per angle you believe in).
- Check every claim against your product sheet and platform policy; verify character counts.
- Run them as a structured test (same audience, same budget, same period), then keep the winner and write the next test.
Before: "Write an Instagram ad for our yoga studio" produces "Transform your body and mind! Join us today!!!"
After: four ads built on the insight "I'm not flexible enough for yoga": a pain angle ("Can't touch your toes? Good. That's where we start."), a social proof angle using a real, consented member quote, a curiosity angle about the 20-minute beginner class, and an objection angle about the free first session, each within limits and with the offer terms.
Worked example (illustrative)
Hana manages social for a modest furniture brand in Jeddah. Her brand project holds the voice guide, product sheet and a list of claims the legal team has approved. For a sofa launch, she generates 15 hooks, picks three, and builds four Meta ad variations across angles. The draft for one variation says "the most durable sofa in Saudi Arabia"; the project's "Facts to verify" line flags it, and she replaces it with an approved fact (a 10-year frame warranty). After a two-week test, the "objection" angle ("Delivered and assembled the same week") wins; she briefs the next round around delivery speed.
Community replies and comments
AI also helps with the other half of social: replying. Keep it human-led:
Here are 20 recent comments on our post (usernames removed). Group them: questions, praise,
complaints, spam. Draft short replies to the questions and praise in our voice.
Do not reply to complaints; list them for me with a suggested next step.Post replies yourself (don't automate publishing), move complaints to a private channel quickly, and never paste customers' personal details into unapproved tools. Replies that sound personal and arrive quickly build more trust than any ad.
Where to go deeper
This lesson is about copy. For campaign structures, bidding, AI campaign types (Performance Max, Advantage+), creative testing at scale and measurement, continue with AI-Powered Performance Marketing.
Pitfalls
- Twenty variations of the same idea; ask for distinct angles.
- Unapproved superlatives and regulated claims.
- Trusting AI character counts.
- Testing too many variations at once with too little budget to learn anything.
How to measure success
Judge copy by the platform metric that matches the objective (thumb-stop rate or hook retention for video, click-through rate for ads, conversions or cost per result for campaigns) and keep a simple log of which angles win for which audience.
Key takeaways
- You supply insight, offer and rules; AI supplies variety across distinct angles; testing decides.
- Generate hooks separately and make them specific; the first line decides whether anyone reads on.
- Respect platform specs and policies: verify character counts yourself and avoid unprovable or regulated claims.
- Test a few distinct variations properly, keep a log of winning angles, and go deeper in the performance marketing course.
