How to Save Money With Facebook A/B Testing—No Matter Your Budget



Whether you have one dollar or thousands of dollars to spend per day on your Facebook ads, keeping costs low by serving great ads is the name of the game. But what you think is a great ad may not actually be the greatest ad. With A/B testing, you can systematically nail down what the data says is the perfect ad for your audience.

But while Facebook A/B testing can help you to lower costs, you may be looking to lower costs precisely because you have a low budget. That’s why we’re going to focus on how to run effective A/B tests in a cost-effective manner.

Read on to learn:

  • Why Facebook A/B testing is important.
  • How to carry out Facebook A/B testing the right way.
  • Types of Facebook A/B tests you can run.
  • Ways to save time and money with Facebook A/B testing.
  • Budgeting tips for Facebook A/B testing.

Why Facebook A/B testing is important

Competing in Facebook ads means you can’t just set it and forget it. Once you launch a campaign, it won’t run consistently—you will need to check in on it, analyze performance, test constantly, and continue optimizing in an effort to see success. Here are some other reasons to run Facebook A/B tests.

  1. Facebook is finicky. What works well for some time may suddenly shift due to algorithmic changes or, quite often, unknown or irrational reasons.
  2. Lower costs. With testing, we can learn, gain valuable insights about our audiences, find out what does and does not resonate with them, and lower our costs over time.
  3. Reach your whole audience. What may captivate one user in an audience may not with another, so it’s best practice to always run tests in your campaigns.

For example, our custom window insert client, Indow Windows, saw a dip in their lead volume and an increase in cost per lead for one lower-funnel ad set.

To see if we could improve performance, we launched a duplicate campaign that optimized for awareness rather than conversions. Within two weeks, we raised their lead volume for this audience 1800% and reduced their cost per lead 94%.

While warmer audiences tend to perform well with lower-funnel campaign objectives, that isn’t always the case, as we can see here. Another added benefit to testing upper-funnel campaign objectives with lower-funnel audiences is that you can accomplish your goals at significantly lower costs (more on that later).

How to carry out Facebook A/B testing (the RIGHT way)

According to Adespresso, a good split test can increase ROI by 10x. So let’s make sure you know all of the steps of a good split test.

1. Determine your goal

The basic concept of Facebook A/B testing is to set a goal and then see which ad variation performs best to accomplish said goal. Here are some examples of goals you might be looking to achieve with your testing:

  • If you are looking to drive more website traffic at a lower cost, test optimizing for link clicks in one ad set and landing page views in another ad set to see which can get you lower CPCs.
  • If you are looking to drive more leads at a lower cost, test out a lead generation campaign objective versus a website traffic campaign objective (where you are sending people to a dedicated lead generation landing page) to see which can get you more leads at a lower cost.
  • If your goal is to drive more video views, test out several video variations using the same copy or one video with several ad copy variations to see which one audiences watch a longer duration, according to the % watched metrics.
  • Looking to improve your CTR? Test 2-3 ad copy variations using one creative in the first round of testing. If the CTR is low (below 1%), this is typically indicative of your ads not resonating with your audience, so test new ad copy. If that doesn’t work, test a new audience. If your CTR is above 1%, test new creatives to see if you can raise it further to a healthy 2%+.

2. Determine your variable

There are dozens of variables to test with your Facebook ads. We’ll go over variables in more depth in the next section, but here is the shortlist:

  • Campaign objectives
  • Audiences
  • Optimization
  • Ad level elements (copy, headline, creative, CTA, etc.)

For this example, let’s say our goal is to increase conversions and our variable is ad copy.

3. Launch your first round of testing

In order for us to understand which ad copy variation is our winner(s), we will want to launch 2-3 ads that are identical except for the ad copy. If we test more than one variable, then we won’t know if it was truly the ad copy that made a difference.

4. Use Facebook’s data AND your own

As your test runs, check in to see how it’s going in the first few days. Make sure the ad set is out of the “Learning Period” before making any optimizations. What you may notice is that Facebook will somewhat quickly choose a favorite one or two of your active ads based on performance. But use your data as well to determine which ad(s) is/are the true winners.

If, for example, Facebook notices fewer impressions with an ad, but your data shows that it has a higher CTR higher or that it’s driving conversions at a lower cost, keep it running! Again, use the data.

5. Disable underperforming ads and move to the next variable

Once you run your ads long enough to see how performance is going, disable the ad(s) that were your underperformers and then determine what you want to test next. Oftentimes, after testing ad copy, we will then test creatives. So we’ll apply the winning ad copy to each of the ads, but change out the creatives to see which combination of copy and creatives are driving the most conversions.

6. Rinse and repeat

Continue building with one single variable at a time. The more we test, find winners, and improve our performance, Facebook rewards us with lower ad costs.

What to A/B test in your Facebook ads

As mentioned above, there are several different variables you can test in your Facebook ads. Just make sure that you’re picking the best one for the metric you want to improve, and that you’re only testing one variable at a time.

Here is a closer look at variables you can test:

1. Campaign objectives

Currently, there are 11 campaign objectives to choose from.

campaign objectives you can compare with facebook a/b testing

Lead gen vs traffic campaign

Perhaps you want to see if you can drive leads using a lead generation campaign and another using the traffic campaign. We do this often for our clients that want to increase sales leads or want to acquire more email subscribers.

What we’ve seen from testing this across accounts and verticals is that lead gen campaigns drive higher lead volumes and at lower costs, however, they tend to also have lower quality leads.

On the flip side, traffic campaigns sending users to a lead generation dedicated landing page to complete a form there and off of Facebook, results in fewer leads at slightly higher costs, however, lead quality tends to be higher as people are more interested to learn more and leave the social platform to complete your form.

While this has been our experience, see how it performs for you and whether quantity or quality are your goal.

Website traffic vs conversion campaigns

Another way to A/B test campaign objectives is to see if you can drive more purchases or other conversions through a website traffic campaign versus a conversions campaign. Both can accomplish your conversion goal but in some instances, we’ve seen traffic campaigns drive more purchases at a lower cost. Upper funnel campaigns tend to be lower in cost, so it may be a worthwhile test for you and an effective way to have your budget go further.

2. Audiences

Test various native and custom audiences in your ad sets. If your goal is to drive people to purchase a water bottle, some audiences you may want to test are people interested in water bottles, another targeting people interested in a competitors water bottle company, and a third may be your customer lookalikes.

3. Optimization

Each campaign type has optimization goal settings within its ad sets. For example, if you use the website traffic campaign, you can optimize for link clicks or landing page views. Test an ad set that uses one of each to see which performs better for you. Do you want more people clicking to the site and getting tagged with the Pixel or do you want perhaps fewer people but more interested in your content and allowing the landing page to fully load? Which one is lower in cost and can still accomplish my goals?

4. Ad level elements

There are plenty of other options to test at the ad set level but let’s move down to the ad level as that too, contains a number of variables that can make or break a campaign and impact costs. For example:

  • Ad copy length (short vs long)
  • Headlines
  • Creatives (single image/video or carousel)
  • Calls to action
  • Landing pages

Determine which you want to test at a given time with your various audiences and campaigns. Remember, don’t test more than variable at a time, unless, of course, you’re running dynamic ads.

3 cost-effective methods of Facebook A/B testing

We know that testing our Facebook ads will ultimately save us money and increase revenue, but it can get expensive. Here are some tactics you can use to test your ads economically.

1. Run dynamic ad campaigns

Manual testing of ads is great, but if you want to move faster in serving ads, testing, learning, and optimizing on a limited budget, dynamic ads are an excellent way to do this.

free widgets for website

Dynamic ads quickly and effectively test various ad level assets while also saving time and money. By leveraging the system to put together combinations of ad copy and creatives together for you, especially in your prospecting campaigns, can give you quick insights through this system-led testing option.

an example of a facebook dynamic ad for facebook a/b testing

If you have a product catalog, set up dynamic product ads in your retargeting campaigns so users that previously looked at those products and didn’t purchase, can come back more efficiently and complete their purchase.

The Facebook dynamic ads feature uses automation to test different combinations of ad copy and creatives for you and will then serve those combinations accordingly.

2. Test upper-funnel campaign objectives

If you have a small budget, say $10/day, but your product or service costs much more than that. You may want to test upper-funnel campaign objectives that are less expensive to have your budget go further.

As we mentioned earlier, if you can’t drive many conversions, particularly for a higher priced product or service, a conversion campaign is not going to perform well and Facebook will charge you quite a bit.

Instead, try an awareness, reach, or website traffic campaign to re-engage with your warm audiences. While the campaign is optimizing for other goals, people can still convert if you add a landing page URL to your ad.

We implement this tactic quite a bit to cut down on costs or help clients find more success on smaller budgets and we often see higher CTRs and lower CPAs compared to some conversion campaigns.

We find that upper-funnel campaign objectives help clients to test on smaller budgets, and often lead to higher CTRs and lower CPAs compared to some conversion campaigns.

3. Use the ad set level budget

Advertisers can choose from two budget setting options in Ads Manager, one of them being at the campaign level using Campaign Budget Optimization (CBO) and the other at the ad set level.

CBO can work well for prospecting audiences that use similar size audiences in the ad sets within, however, it does not work very well for small audiences, as we may see when testing smaller budgets or in retargeting campaigns. When working with smaller budget accounts, we typically recommend using ad set level budget so you have more manual control on how much you spend, how, and where.

When working with smaller budget accounts, we typically recommend using ad set level budget so you have more manual control on how much you spend, how, and where.

How much should I budget for Facebook A/B testing?

You can start with as little as $1/day. Yes, you read that right. Though, there are some caveats. It depends on your campaign type.

With top-of-funnel campaigns such as reach, awareness, and engagement, we have seen success in running ads and boosted posts to various audiences.

free widgets for website

However, if you want to test lower-funnel consideration or conversion campaigns, a budget that small will not do.

The smaller your budget, the slower the testing, learning, and optimizing will be. The more budget you can allocate, the quicker you can get out of the Learning Period, serve impressions, acquire performance data, learn, and take your next optimization steps.

If you can, try to spend at least $10/day to start and as you begin seeing good results and as you’re maxing out on your daily budget, increase your daily budget 10-15% per day.

If you scale too quickly, that can sometimes backfire if Facebook isn’t able to spend your budget that day and then it may lower the quality of your campaign, thus raising costs. This way, you can learn and grow without wasting money and scale forward.

How to test Facebook ads on a budget: recap

Facebook A/B testing is important not only because it affords us valuable insights and saves us money, but also because Facebook frequently undergoes algorithm changes. Let’s close off with a brief summary of how to run Facebook A/B tests on a budget:

free widgets for website

The basic process of Facebook A/B testing is:

  • Determine your goal
  • Determine your variable
  • Launch your first set
  • Let data accumulate
  • Disable underperforming ads
  • Clone the winner and test a new variable
  • Repeat

Some of the best variables to test on a budget include:

  • Campaign objectives
  • Audiences
  • Optimization
  • Ad level variables

The best way to test your Facebook ads on a budget is to:

  • Run upper-funnel tests
  • Test upper-level campaign objectives
  • Use the ad set level budget

Finally, if you can, try to spend at least $10/day to start and as you begin seeing good results, increase your daily budget 10-15% per day.

Facebook-Meta Earns the ‘Worst Company of 2021’ Title in This Survey




Facebook has had its share of controversies this year. The company was under more scrutiny after whistleblower Frances Haugen leaked a series of internal documents.

Facebook parent Meta has been named the Worst Company of the Year (2021) by Yahoo Finance respondents. According to the publication, an “open-ended” survey was published on Yahoo Finance on December 4 and 5, where 1,541 respondents participated. Facebook received 8 percent of the write-in vote, but respondents were seemingly mad about the Robinhood trading app as well. Electric truck startup Nikola, which was named last year’s worst company by the same publication also faced respondents ire.

Yahoo Finance notes, “Facebook has had its share of controversies this year.” Starting in January, Meta-owned WhatsApp got caught up in a huge controversy after the messaging app announced a new privacy policy (Terms of Service). WhatsApp said it would collect user information and share it with third-party apps for a better user experience. However, the app gave users no choice but later made modifications to the policy under pressure. Similarly, the company was under more scrutiny after whistleblower and former Facebook employee Frances Haugen leaked a series of internal documents showing the company’s problematic practices. It was revealed that Meta-owned Instagram had a negative impact on teenage girls, but the company did almost nothing to rectify the problem.

Yahoo Finance even highlights, “At the same time, some critics, including conservatives, say Facebook over-policed the platform’s speech and stifled their voices.” Critics also blame Facebook and other social media platforms for not curbing hate speech that led to Capitol Building riots.

However, around 30 percent of Yahoo Finance readers said that Facebook or Meta could redeem itself. One respondent suggested that the company could issue a formal apology for negligence and donate a sizable amount of its profits to a foundation to help reverse its harm.

On the other hand, respondents chose Microsoft as the Company of the Year (2021). The Satya Nadella-led company touched the trillion-mark this year and introduced notable upgrades. The most notable is the Windows 11 OS update that succeeds Windows 10.

Facebook pays 1.7 Cr fine to Russia after failing to delete content Moscow deems illegal





In the latest legal tussle with Russia over controversial social media regulation laws, Facebook paid 17 million roubles (Rs 1.7 Crore) for failing to remove content deemed illegal by Moscow. With a threat of potential larger fines looming, Facebook parent company Meta, owned by Mark Zuckerberg, is scheduled to face court next week over repeated violations of Russian legislation on content, Interfax News Agency reported. As per the latest updates, the social media giant could be fined a percentage of its annual revenue.

In October, Moscow sent state bailiffs to enforce the collection of 17 million roubles. Meanwhile, as per Interfax report citing a federal bailiffs’ database, on Sunday, there were more enforcement proceedings against the company. Apart from the popular social media app, Telegram has also paid 15 million roubles in fines for failing to comply with the Russian social media legislations that came into force in 2016.

Facebook pays $53k to Russia for refusing controversial social media laws

It is pertinent to mention that Facebook has locked horns with Moscow earlier in November, resulting in it paying 4 million roubles ($53,000) over its refusal to adhere to Russian data localisation laws, the Moscow Times reported. The Moscow court on November 25 had said that Facebook paid the fine levied in February, following which all proceedings against the US-based social media giant. The payment comes against the litigation filed against the company in 2018, alongside Twitter. The tech companies were also forced to pay an additional 3000 rubles ($40) for failing to comply with user data sharing rules as per the law. The Russian authorities have also previously blocked LinkedIn, owned by Microsoft, for failing to abide by the laws.

Russian social media laws

As per Moscow Times, under the Russian social media regulation laws, all foreign technology companies are required to store data related to Russian customers and users on servers located in Russia. Additionally, the Russian tech companies will also have to share encryption data with the federal authorities as well as record user calls, messages and civil society group conversation records. The apparatus is said to be a severe breach of privacy rights and unfettered back-door access to personal data that could be used to harass Kremlin critics.

Facebook Messenger Is Launching a Split Payments Feature for Users to Quickly Share Expenses




Facebook Messenger Is Launching a Split Payments Feature for Users to Quickly Share Expenses

Meta has announced the arrival of a new Split Payments feature in Facebook Messenger. This feature, as the name suggests, will let you calculate and split expenses with others right from Facebook Messenger. This feature essentially looks to bring an easier method to share the cost of bills and expenses — for example, splitting a dinner bill with friends. Using this new Split Payment feature, Facebook Messenger users will be able to split bills evenly or modify the contribution for each individual, including their own.

The company took to its blog post to announce the new Split Payment feature in Facebook Messenger. 9to5Mac reports that this new bill splitting feature is still in beta and will be exclusive to US users at first. The rollout will begin early next week. As mentioned, it will help users share the cost of bills, expenses, and payments. This feature is especially useful for those who share an apartment and need to split the monthly rent and other expenses with their mates. It could also come handy at a group dinner with many people.

With Split Payments, users can add the number of people the expense needs to be divided with and, by default, the amount entered will be divided in equal parts. A user can also modify each person’s contribution including their own. To use Split Payments, click the Get Started button in a group chat or the Payments Hub in Messenger. Users can modify the contribution in the Split Payments option and send a notification to all the users who need to make payments. After entering a personalised message and confirming your Facebook Pay details, the request will be sent and viewable in the group chat thread.
