What Should I be Testing on Meta?

What Should I be Testing on Meta?

TLDR


Meta's Andromeda AI now decides which ad gets shown to which person — automatically. The more creative variety you give it, the better it performs.
  • The old playbook (one great ad + tight targeting) is dead. Creative diversification is now the primary lever for Meta ad performance.
  • Andromeda's results speak for themselves: 9% lower cost per action, 11% higher CTR, 7.6% higher conversion rate, 8% better ad quality overall.
  • "Creative diversity" just means changing the creative variables to multiply the amount of pieces of content you get.
  • People buy from people who look like them. The demographic lever is the most underused and highest upside variable in most ad accounts right now.
  • Brands winning on Meta aren't the ones with the biggest budgets. They're the ones feeding the algorithm the most options.

Meta quietly published a piece of research that should change how every business owner thinks about their ad creative.

It's about a new AI ad system called Andromeda. If you're still running one set of creatives to one audience and hoping it converts, then keep reading cause you've got some catching up to do.

For years, the standard advice was: know your audience, narrow your targeting, and get really specific about who you're talking to.

That was great advice for a different era / platform of advertising. But don't just listen to me, the data from Meta themself backs it up.

The Numbers

11% higher click-through rate with AI-generated image features
7.6% higher conversion rate using Advantage+ creative tools

How Andromeda Actually Works:

Meta describes Andromeda as a next generation AI model that works behind the scenes to figure out which ad to show which person at which moment.

The key words there are "which ad."

Andromeda isn't just optimizing bids and placements. It's doing deep personalization by matching creative to people based on signals most advertisers can't even see. It has already driven an 8% improvement in overall ad quality across the platform.

But here's the thing: it can only personalize across the creative options you give it.

If you upload one ad, Andromeda can only show one ad. If you upload twenty, then it has twenty chances to find the right match.

This is why Meta is calling creative diversification the single most important lever in modern paid advertising.

What Exactly is Creative Diversity?

Creative diversification just means giving the algorithm more information to work with across three main variables.

The Format:

The same core message can become a talking head video, a static image, a carousel, or a text based ad. Each format finds different people in different moods. Running the same message across multiple formats is one of the fastest ways to increase your creative footprint without blowing up your budget.

The Emotional Angle:

Lead with pain. Lead with aspiration. Use humor. Use social proof. Some people respond to "tired of wasting money on ads that don't work?", while others respond to "imagine what your business looks like when your content actually converts." Both can be true. Both should be tested.

And The Demographics:

This is the most underused lever in most ad strategies, and it's where Andromeda really shines. People buy from people who look and act like them. When someone sees a person in an ad who resembles them, whether in age, background, energy, or lifestyle, their guard drops. Trust builds faster when people feel they can relate to the people in the ads.

What This Means For You


The brands doing this well aren't necessarily the biggest brands with the biggest budgets. They're the ones who understand that the algorithm is now their media buyer, and their job is to give it great creative to work with.

Ben & Jerry's used Meta's Advantage+ creative tools for background image generation and saw a 7% increase in link clicks compared to their standard creative approach.

DribbleUp scaled to nearly 50 creatives per week and maintained strong performance by keeping creative production tight, fast, and diverse.

The moral of the story is: Stop treating creative as a one off decisions and started treating it as a system. You'll perform far better by outsourcing the creative to a bunch of different creators than you will by trying to manage the entire production pipeline for each piece of content you run ads on. That allows for far more creative diversity and far less time of you stressing over what your next batch will be.

The good news is that building that system doesn't require a bigger team or a bigger budget, it just requires a smarter process.

That's exactly what we help our clients build at Good Post House.
