Good ad copy is the difference between a scroll and a click.

If you’ve ever stared at a blank screen trying to write a Facebook ad headline, you know the problem. You need ideas, you need variations, and you need them to actually convert.

Here are three tools I use. Each one does something different.

1. Unicorn Ads

Before I write anything, I look at what’s already working.

Unicorn Ads is a free ad library. It shows you Facebook and Instagram ads from the top 1,000 Shopify stores — filtered by niche.

Pick your category. Fashion, fitness, skincare, electronics — whatever you’re selling. Click on any brand and it takes you straight to their Meta Ad Library. You see every ad they’re running right now.

You’re not guessing. You’re seeing what brands with real budgets are putting money behind.

I use this to spot patterns. What hooks are working? How long is the copy? Are they leading with a benefit or a testimonial? 15 minutes here saves me hours of guessing later.

Best for: Building a swipe file of real Facebook and Instagram ad examples without doing it manually.

2. Writesonic

Once I know the direction, I need options.

Writesonic is an AI copywriter. It has templates for Facebook ads, Google ads, LinkedIn ads, landing pages — pretty much anything you’d need.

You give it your product name, a short description, and who you’re targeting. It gives you multiple variations in seconds.

The useful part — it writes using proven formulas like AIDA and PAS. So the structure is already there. You’re not starting from zero.

I don’t use the copy as-is. I generate 10 variations, pick the strongest 2-3 angles, then rewrite in my own voice. It’s a starting point, not a final draft.

When you’re A/B testing ads, this saves a lot of time. Instead of writing five versions yourself, you generate ten and choose the best.

Best for: Getting ad copy variations fast — especially for Google ads, Meta ads, and PPC campaigns.

3. UnicornCopy.AI

This one works differently.

You don’t describe your product. You paste your landing page URL. The AI reads your page and writes ad copy based on what’s already there.

It gives you 100-150 variations — sorted by type. Feature-based, benefit-driven, storytelling, urgency. You pick what fits.

Here’s what makes it different. The AI was trained on 11,500 top-performing Facebook ads. Ads that made over $1.5 billion in sales combined. So the copy isn’t generic — it’s based on what actually converted.

Another thing — your ad copy matches your landing page. That consistency matters. When someone clicks your ad and lands on a page that says the same thing, they’re more likely to convert.

Best for: Ecommerce brands running Facebook or Instagram ads who want copy that’s built on real performance data.

But Here’s the Thing

Great ad copy gets the click. But if your landing page doesn’t convert, you’re paying for traffic that goes nowhere.

At Massive Impact, we build marketing systems that turn clicks into customers — custom websites, SEO, and PPC campaigns designed to bring in high-quality leads consistently. If your ads are working but your conversions aren’t, that’s where we come in.

Three tools. Each one solves a different problem.

Unicorn Ads when you need inspiration. Writesonic when you need variations fast. UnicornCopy.AI when you want copy trained on ads that actually worked.

Use whichever one fits where you’re stuck.
