How do you know if your Facebook ads are effective? This is a question that thousands of our clients face. When you start an advertising campaign on a Facebook ad account, you will need to run tests. Testing is incredibly important because it will help your Facebook ads deliver high-impact results. However, not everyone has experience in ad testing, and most advertisers do it incorrectly. This blog post will be a gift for you; it will guide you through the detailed steps of how to properly test Facebook ads, helping you optimize your ads in the best way possible.
Before we get into the most effective ways to test Facebook ads today, I want to tell you this: Let your ads run longer, for more time. You heard that right—Facebook’s operating mechanism works effectively when it has more data. Your Facebook ads will be successful when that campaign collects the most conversion data. So, how can you know if your ads are converting well?
Tips for creating high-converting Facebook ads
When starting a Facebook ad campaign, most people don’t give their ads enough time to be tested. Running an ad for a long enough period will help you determine if new ad creatives, content, headlines, images, and calls to action are effective. The ideal time to figure out if an ad is working is 7–10 days, though you can adjust this depending on the number of conversions and the campaign budget.
I’ll give you an example to help you understand better:
For a business generating 1,000 to 2,000 orders a day, you can get test results very quickly, in just a few hours, though we usually let it run for a few days. Conversely, if you only get 5 conversions a week, we recommend spending weeks or even longer to see if the ad is effective. For campaigns with low conversions, I advise testing multiple campaign styles and letting them run for a long time to determine if the content is good and if it needs to be adjusted.
In addition, you can rely on ad performance metrics to measure if an ad creative is effective. From there, you’ll know whether to let the ad continue running or pause it. For example, if your target CPO (Cost Per Order) is $30 but your current CPO is $35, you can let it run for a bit longer to give Meta time to optimize. But if your CPO is $60, which is double your target, you can stop it early and move on to a different idea.
Quality over quantity
Many advertisers mistakenly believe that they must test a large number of ad creatives to succeed. While you do need to test creatives, you shouldn’t test too many different ones at the same time. You should separate your Facebook ad types to know exactly what is driving results: test an image versus a video, but keep the headline, content, and offer the same. After you have results, then move on to other factors, such as keeping the image the same and changing the content, headline, or call-to-action button.
To measure effectively, I recommend creating 4-5 excellent ad creatives and 20 mediocre ones. The number of ad creatives you can test at once also depends on your budget and conversion goals.
Preparation steps for ad testing
Create a plan
Before you test, you must clearly define your objective. For example: “UGC ads will be more effective than our current ads.” In that case, you need multiple different UGC creatives to compare with your current ad group, rather than just one.
Prioritize testing the factors with the biggest impact first:
- Product/Service – which one sells best?
- Offer – you can increase urgency, add a warranty, change policies, etc.
- Creative format & style – UGC, demo videos, influencer content, carousels, single images, etc.
- Headline
- Primary Text
- Call-to-Action Button (CTA)
- Description
Start with the difficult parts (product, offer, quality video), because that’s where competitors do less work, and you can gain a significant edge.
Finding ideas to test
The first step is to find and copy your competitors’ high-converting ads. Copy them based on the following factors:
- Look at your competitor’s 5-star reviews → incorporate those strengths into your ad creative.
- Look at your competitor’s 1-star reviews → advertise that you don’t make those same mistakes.
- Get ideas from similar industries to create a competitive advantage. Find high-quality content and copy it to make it your own.
How to creatively test Facebook ads
Today, our team at Optimal Agency will show you how to test ads from low to high budgets. These are highly effective ad testing steps that very few people will share with you.
Testing creatives for low budgets ($1,000–$15,000/month)
With this type of budget, we recommend creating a single campaign. We recently set up a few initial campaigns for new brands, and here’s exactly how I did it: you’ll get initial data on your creatives without complicating your account structure.
We recommend running a Sales Campaign optimized for Purchases. Don’t use Traffic, Engagement, or Add-to-Cart Campaigns. Meta’s 2025 algorithm is smart enough that you just need to be clear about what you want (in this case, purchases).
Limit yourself to about 10 initial ad creatives, prioritizing static ads because they’re easy to make and help you see which messages are effective. You can also add UGC-style ads or UGC-style Founder ads if they’re available.
Types of static ads you should test:
- Benefit Callout Ads (highlighting key benefits)
- Us vs. Them Ads (comparing you to competitors)
- Headline Ads (with a strong headline)
- “Ugly Ads” (simple, eye-catching designs)
- Testimonial Ads (an image + a customer review)
A Note: You should use an Advantage+ Shopping Campaign (ASC) to test creatives at a low budget because:
- It allows you to test more creatives within a simple campaign structure.
- It’s easy to manage and optimize, especially if you’re working alone.
- You don’t need to worry about splitting ad sets, adjusting audiences, or retargeting.
Growth Testing with a budget of $30,000–$50,000/month
At this level, you’ll focus on two core campaigns:
- Maintain the ASC campaign from the previous stage (if it’s still effective).
- Add a manual Creative Testing Campaign (not an ASC).
Structure:
- Each ad set = 1 creative testing idea.
- Each ad set contains 3–6 creatives (depending on the budget).
- Budget: $100–$200/ad set/day.
- You can use ABO to get results quickly, or CBO if it fits your strategy.
Notes on Facebook Testing:
- Focus heavily on video ads.
- Create a variety of videos with different messages and hooks.
- Test ads with various video lengths.
Large budget phase (Scale) – Over $1 Million/month
At this stage, you should create one creative testing campaign.
- Testing can use a cost cap because you already know your target CPA.
- Testing speed and volume increase dramatically: 10–20 tests/week.
- Testing involves more minor adjustments (small variations) rather than major changes.
- Creatives become more diverse: celebrity ads, major influencers, high-production videos, and professional founder ads.
How to run it:
- Budget is around $200 per ad set per day.
- Test for 7 days or until you’ve spent about $1,000 per ad set.
- If a creative wins early, scale it immediately.
Conclusion
We want you to understand this clearly: there is no “single formula” for Meta Ads. A mindset of testing and a curiosity about what makes customers decide to purchase is the decisive factor that drives conversions. In the early stages, 9 out of 10 times, the problem is with the creative, not the campaign structure. This article has provided steps to help you better understand how to perform ad tests.
