Day 188: Why You Shouldn’t Trust Facebook’s Numbers Alone

Today’s update focuses on something that every advertiser eventually discovers.

The numbers reported inside Facebook Ads Manager are not always accurate.

That doesn’t mean the platform is useless for tracking performance, but it does mean you should never rely on it as your only source of truth. The key is learning how to interpret the data properly and compare it against your own systems.

Key Takeaways

Facebook’s reported sales numbers often differ from your actual sales data.

Comparing CPA and average order value gives a clearer picture of performance.

The new “15 Minutes of Fame” ads are now the best performers in the campaign.

Landing page messaging will now be updated to match the new ad hook.

Performance Snapshot

Yesterday turned out to be a very strong day. Sales came in at $1,037.

Ad spend was £394, which translated to roughly $527. That left a profit of approximately $500 for the day.

That result is very close to doubling the ad spend, which is exactly where the funnel needs to be performing. It was also an excellent recovery considering the ad campaign had recently been disrupted.

Today’s Early Numbers

Today’s sales were sitting at $389 around 12:30pm.

That’s not a bad position at that stage of the day. While it’s still a long way from the $1,000 mark, there is plenty of time for the numbers to climb further.

Daily performance always fluctuates, so the focus remains on the broader trend rather than a single day.

Why Facebook Numbers Can Be Misleading

The main lesson from today is about how Facebook reports results.

Looking at yesterday’s performance, Facebook reported 27 purchases from the ads. However, when looking at the new customer contacts added to the email system, only 20 were recorded.

Checking the sales page itself showed another number entirely, which was 25 purchases.

So from one single day we ended up with three different numbers: 27, 25, and 20.

Why Data Discrepancies Happen

These discrepancies happen for several reasons.

Some customers complete purchases but never create a full account inside the course platform. Others may complete the purchase later after clicking the ad earlier in the day.

There can also be delays in tracking events or differences in time zones between systems.

Because of this, relying purely on Facebook’s numbers can easily lead to incorrect conclusions.

The Metric That Actually Matters

Rather than worrying about the exact number of purchases reported by

Facebook, the main metric to focus on is cost per acquisition.

The calculation is simple. Look at how much was spent on advertising and divide that by the number of new customers actually acquired.

This provides a far clearer view of performance than relying on the platform’s attribution numbers.

Comparing CPA and Average Order Value

Once CPA is known, the next step is comparing it to average order value.

As long as the average order value is significantly higher than the cost per acquisition, the funnel remains profitable on the front end.

Any additional revenue generated from backend offers simply increases the margin further.

For example, February’s CPA averaged roughly $43 to $44. If the funnel continues producing an average order value significantly above that number, the business stays profitable.

Learning Phase Recovery

Another encouraging update is that the ads have now exited Facebook’s learning phase.

After the accidental deletion of the ad set earlier in the week, the campaign had to restart and accumulate conversions again.

Over the past few days the ads generated 62 purchases, which pushed the campaign past the learning phase threshold.

That means the algorithm can now fully optimise again.

Performance of the New Ad Hook

Looking at the current results, the best-performing ad is now the “15 Minutes of Fame” creative.

That ad is currently producing purchases at around £9.17 each, which is an excellent cost per acquisition.

Even better, the second and third variations of the same concept are also generating consistent sales.

The click-through rates on these ads are also strong, which suggests the message is resonating with the audience.

Next Step: Updating the Landing Page

Since the new messaging angle is working well in the ads, the next logical step is extending that concept into the landing page.

The plan now is to write a new version of the landing page that focuses heavily on the “15 Minutes of Fame” concept.

The messaging will highlight how quickly someone can learn famous riffs and start sounding impressive on the guitar.

Once the new page is built, it will be split tested against the current landing page.

Why Consistency Improves Conversions

One of the biggest factors in improving conversion rates is consistency between the ad and the landing page.

When someone clicks an ad promising a specific outcome, the landing page should reinforce that exact same promise.

If the new messaging continues performing well in ads, aligning the landing page with it could potentially increase conversions further.

Closing Reflection

Today’s lesson is simple but important. Advertising platforms provide useful insights, but their data should never be treated as absolute truth.

The most reliable numbers always come from your own sales systems and customer records.

By focusing on real customer acquisition costs and revenue per customer, it becomes much easier to understand whether a funnel is actually working.
