Ad Copy That Converts

⏱ 7 min 📊 Beginner

Running an e-commerce store without paid ads is like opening a shop on a quiet side street and hoping people wander in. Ads are the megaphone. They put your products in front of people who are already looking to buy.

The problem? Writing ad copy is tedious. You need headlines, body text, CTAs — and you need different versions for Facebook, Instagram, Google Shopping, Pinterest, and TikTok. That used to take a full day. Today you'll learn how to generate 20 high-converting ad variations in 10 minutes.

The anatomy of a great ad

Every high-converting ad has three parts, regardless of platform:

The hook — The first line or image that stops the scroll. You have less than 2 seconds. Lead with a pain point, a bold claim, or a visual that demands attention. "Still using a kitchen knife that goes dull after a week?" is a hook. "Check out our new knife" is not.

The body — This is where you deliver the value. Benefits, not features. "Stays sharp for 5 years" beats "Made from VG-10 Japanese steel." Social proof works here too — "Over 12,000 home cooks switched this year."

The CTA — Tell them exactly what to do. "Shop now — free shipping today" is clear. "Learn more" is vague. The more specific and urgent your CTA, the higher your click-through rate.

Platform-specific ad copy

Each platform has its own rules. AI helps you adapt one product message across all of them in minutes:

Facebook/Instagram Ads — Primary text (125 characters visible before "See more"), headline (40 characters), description. Emotional hooks work best. Lead with the problem your product solves.

Google Shopping — Product title (150 characters max) and description. Keywords matter here — "Women's Waterproof Hiking Boots Size 8" outperforms "Amazing Hiking Boots." Be specific and searchable.

Pinterest — Pin titles (100 characters) and descriptions (500 characters). Pinterest users are planners and dreamers. Aspirational copy works: "The weekend bag you'll take on every trip."

TikTok Shop — Short, punchy, conversational. Write like you talk. "POV: You finally found a water bottle that actually keeps ice frozen for 24 hours." TikTok rewards authenticity over polish.

Knowledge Check

What's the key difference between writing for Google Shopping vs. TikTok Shop?

A

Google Shopping needs keyword-rich, specific copy while TikTok needs casual, conversational copy

B

There's no meaningful difference between the platforms

C

TikTok requires more professional language

D

Google Shopping allows longer descriptions

Google Shopping is a search engine — people are typing specific queries, so your copy needs keywords and product details they're searching for. TikTok is a discovery platform — people are scrolling, not searching. Your copy needs to feel like a friend recommending something, not a product listing. AI can adapt the same product to both styles in seconds.

Headlines that sell

The headline is the single highest-impact line of copy in any ad. A great headline can double or triple your click-through rate compared to a mediocre one.

Here are headline formulas that consistently convert for e-commerce:

Problem-solution: "Tired of tangled earbuds? These stay put for 12 hours."

Social proof: "47,000 dog owners switched to this leash. Here's why."

Specificity: "Save 23 minutes every morning with this meal prep container."

Curiosity: "The $29 skincare product dermatologists don't want you to know about."

Urgency: "Last 6 hours: 40% off our bestselling backpack."

Ask AI for 10 headline variations using different formulas. Pick the top 3 for A/B testing. The best-performing headline often surprises you — it's rarely the one you'd have written yourself.

Knowledge Check

Why should you generate multiple headline variations instead of going with your first idea?

A

AI always writes bad headlines on the first try

B

Platforms require you to submit multiple headlines

C

More headlines mean more keywords for SEO

D

Different emotional triggers resonate with different audiences — testing reveals what actually converts

What sounds clever to you might not resonate with your customer. A headline driven by curiosity might outperform one driven by urgency — or vice versa. You can't predict this. But you can test it. AI lets you generate 10 variations in 30 seconds, so A/B testing becomes effortless instead of time-consuming.

Body copy and CTAs

Your body copy should do one thing: move the reader from the headline to the CTA. Every sentence should build desire and reduce friction.

Body copy rules for e-commerce:

- Lead with benefits, back up with features

- Use specific numbers — "Lasts 3x longer" beats "Lasts a long time"

- Address the #1 objection in the ad itself — "Free returns, no questions asked"

- Keep it scannable — short sentences, line breaks, bullet points

CTA rules that increase conversions:

- Add urgency: "Shop now — sale ends tonight"

- Reduce risk: "Try it free for 30 days"

- Be specific: "Get your starter kit — $29" beats "Buy now"

- Match the ad promise to the landing page — if the ad says "40% off," the landing page better show 40% off

I'm launching a new organic bamboo bed sheet set on my Shopify store. Price: $89 (competitor average is $120+). Key selling points: softer than cotton, temperature-regulating, eco-friendly, 60-day trial. Write a complete Facebook ad campaign with 4 ad variations — each using a different angle: comfort, value, eco-friendly, and social proof. Include primary text, headline, and CTA for each.

Here are your 4 Facebook ad variations: **AD 1 — Comfort angle:** Primary text: You know that feeling when you slide into a hotel bed and think "why can't my bed feel like this"? Now it can. Our organic bamboo sheets are softer than 1,000-thread-count cotton — and they keep you cool all night. No more waking up sweaty at 3 AM. Headline: Sleep Like a Hotel. Pay Like a Human. CTA: Shop Now — 60-Day Risk-Free Trial --- **AD 2 — Value angle:** Primary text: Premium bamboo sheets usually cost $120–$180. We cut out the middlemen and sell direct. Same quality. Same luxury feel. $89. And if you don't love them in 60 days, send them back — we'll even pay for shipping. Headline: $89 Bamboo Sheets That Feel Like $200 CTA: Get Yours — Free Shipping Today --- **AD 3 — Eco-friendly angle:** Primary text: Cotton farming uses 10,000 litres of water per sheet set. Bamboo uses 1/3 of that — and grows back in 3 months without pesticides. Our sheets are better for the planet AND softer on your skin. Sleeping well just got a lot more guilt-free. Headline: Softer Sheets. Smaller Footprint. CTA: Shop Sustainable — $89 with Free Shipping --- **AD 4 — Social proof angle:** Primary text: "I've bought luxury sheets from brands 3x the price. These are better. I'm not exaggerating." — Sarah M., verified buyer. Over 2,400 customers have switched to our organic bamboo sheets. The average rating? 4.8 out of 5 stars. Headline: 2,400+ Customers Can't Be Wrong CTA: Try Them Risk-Free — 60 Days to Decide --- I'd recommend running all 4 simultaneously with a $10/day budget each for 5 days. Kill the bottom 2 performers, scale the top 2. Want me to write the Google Shopping listing and Pinterest pins too?

The 20-ad method

Here's how experienced e-commerce sellers use AI to create a full ad library in minutes:

Step 1: Write one detailed product brief. Include the product name, price, key features, target customer, main competitor price, and your unique selling point.

Step 2: Ask AI for 5 headline variations using different emotional angles.

Step 3: Ask AI for 4 body copy variations — one for each platform (Facebook, Google, Pinterest, TikTok).

Step 4: Ask AI for 3 CTA variations with different urgency levels.

Step 5: Mix and match. Five headlines times four body variations is 20 unique ad combinations. Test the top performers.

This process takes about 10 minutes. Without AI, creating 20 polished ad variations would take a full day — or cost $500+ from a freelance copywriter. You'll do it before your morning coffee gets cold.

Knowledge Check

What's the biggest advantage of generating 20 ad variations instead of running just one?

A

You can A/B test different angles and let real data show you what converts — removing guesswork

B

It makes your ad account look more professional

C

More ads always means more sales

D

Platforms reward accounts that run more ads

One ad is a guess. Twenty ads is a testing system. You might be sure the eco-friendly angle will win — but the data might show that the social proof angle gets 3x more clicks. The only way to know what actually converts is to test. AI makes testing free and fast, so there's no reason to guess.

Knowledge Check

In a Facebook ad, what should the primary text lead with?

A

A hook that addresses a pain point or desire the customer already has

B

A discount code and price

C

A detailed list of product specifications

D

Your brand story and company history

The primary text is the first thing people see. If it doesn't hook them in the first line, they scroll past. Leading with a pain point ("Tired of sheets that make you sweat?") or desire ("Imagine sliding into the softest sheets you've ever felt") creates an emotional connection before you ever mention the product.

Adapting copy for retargeting

Not every ad targets cold audiences. Some of your highest-converting ads will be retargeting ads — shown to people who already visited your store but didn't buy.

Retargeting copy is different from cold-audience copy:

Cold audience: "Discover the softest bamboo sheets you'll ever own."

Retargeting: "Still thinking about those bamboo sheets? They're still in your cart — and shipping is free today."

The tone shifts from introduction to gentle nudge. AI can write both types once you tell it who the ad is for. Just include "This ad targets people who visited my product page but didn't purchase" in your prompt, and the copy will adjust automatically.
