Facebook ads audit checklist: what to check first

Short answer: A good Facebook ads audit checks five things in order: tracking, account health, campaign structure, creative and reporting. Start with tracking, because if the Pixel and Conversions API are sending wrong or duplicated events, every other number in the account is unreliable. This Facebook ads audit checklist walks through what a specialist looks at first, what problems to look for, and what to fix before you spend another dollar.

Before you start: access and context

An audit is only useful if it is judged against your real business. Before opening Ads Manager, gather:

• Your goal: sales, leads, bookings or app installs, and what a good result is worth to you.
• Real numbers from your shop or CRM for the same period you will review in Meta.
• Your margins or a target cost per acquisition, so results can be judged as profitable or not.
• Access to the business portfolio, ad account and Events Manager. Analyst access is enough for most audits.

Review at least the last 30 to 90 days, depending on spend. Small accounts need a longer window to show patterns.

1. Tracking and data quality

Meta’s delivery system optimises towards the events you send it. The Conversions API documentation notes that server events are processed like Pixel events, and that you should verify events are received, deduplicated and matched correctly. In Events Manager, check:

1. Which events fire, and whether each one fires on the right page or action.
2. Whether the Pixel and Conversions API both send key events, and whether duplicates are being removed.
3. Whether purchase events carry a value and currency.
4. The Event Match Quality score for your main conversion events.
5. Any warnings in the diagnostics tab.
6. How Meta’s reported conversions compare with your real orders or leads. A big gap in either direction needs explaining.

Also check your attribution settings and how you read them. Meta changed its definition of click-through attribution in March 2026 so it now requires a link click, with likes, saves and short video views counted separately as engage-through. If reported conversions dropped around that time, the definition change may explain part of it.

2. Account health and setup

• Ownership: the business portfolio, ad account, Pixel or dataset, Facebook Page and Instagram account should be owned by the business, not by a former employee or agency.
• People and partners: remove anyone who no longer needs access.
• Account Quality: look for rejected ads, restrictions or policy warnings, and fix repeated rejections before they become a bigger problem.
• Billing: check payment method, spending limits and any failed payments that pause delivery.
• Domain: confirm your website domain is verified in the business portfolio.

If campaigns are not spending at all, my post on why Facebook ads stop delivering covers the common causes.

3. Campaign structure and budgets

Structure problems are among the most common audit findings. Meta’s ad sets need data to learn. The long-standing guidance is about 50 optimisation events per ad set in a seven-day period to exit the learning phase, and ad sets that cannot get there show as Learning Limited. Check:

• How many active campaigns and ad sets there are, and whether budget is split too thinly.
• How many ad sets sit in Learning or Learning Limited.
• Whether the optimisation event matches the goal. Optimising for link clicks when you want sales is a common mistake.
• Overlapping audiences across ad sets that compete with each other.
• How often significant edits are made. Constant changes keep resetting learning.
• Whether automated options such as Advantage+ sales campaigns and Advantage+ audience are used, and whether that choice was deliberate.

Many experienced practitioners now favour consolidation. Jon Loomer’s complete approach to Meta ads starts with one campaign and one ad set, and adds more only when there is a real reason, such as a different product line or goal. The same brief suggests using the breakdown by attribution setting to separate view-through results from click-driven ones, which is a useful audit step in itself.

4. Creative and ads

Meta’s Andromeda retrieval system was built to handle a large and growing volume of ad creative and match ads to individual people. In practice that makes creative variety one of the biggest levers in the account. When auditing ads, look at:

1. Volume and age: how many active ads there are, and when the last new ones launched.
2. Variety: are the ads genuinely different in angle and format, or small variations of one idea?
3. Fatigue: rising frequency with falling click-through rate and rising cost per result.
4. Spend concentration: whether one or two ads take almost all the budget, and whether they still deserve it.
5. Placement fit: vertical video for Reels and Stories, and text that is readable on a phone.
6. Message match: the ad’s promise should match the landing page.

If there is no testing process at all, that is a finding on its own. My guide to Facebook ad creative testing outlines a simple one.

5. Landing pages and the funnel after the click

Many Meta accounts look broken when the real problem is on the website. Check landing page speed on mobile, whether the offer and price are clear, how many steps it takes to buy or enquire, and whether the checkout or form works on common phones. For lead generation, also check how fast leads are followed up and whether lead quality is tracked at all.

6. Reporting and recommendations

Finally, look at how results are reported. Good reporting ties spend to sales, revenue or qualified leads, and compares Meta’s numbers with the business’s own data. Be careful with in-platform scores. Meta’s Opportunity score, for example, measures how many of Meta’s recommendations you have adopted, not your performance, so a low score is not proof that anything is wrong.

After the Facebook ads audit checklist: what I recommend fixing first

Do not try to fix everything at once. Big simultaneous changes reset learning and make it impossible to see what helped. I recommend this order:

1. Fix tracking and ownership issues first.
2. Make sure campaigns optimise for the right event.
3. Consolidate structure where budget is spread too thin.
4. Launch a steady flow of new, varied creative.
5. Improve landing pages and follow-up.
6. Re-check results after two to four weeks.
