If your Facebook or Meta ad account isn’t converting as expected - even with a seemingly solid ROAS (Return on Ad Spend), you’re not alone. Many advertisers fall into the trap of trusting on-platform metrics alone, only to realize they are scaling unprofitable campaigns. As platform tracking becomes less reliable due to privacy changes and algorithmic shifts, a thorough, data-driven audit is essential.
An audit helps uncover where ad spend is being wasted, whether that’s because of poor tracking, misaligned campaign structures, or ad fatigue. It allows you to move beyond surface-level data and find the real levers for growing returns.
In this guide, we’ll take you through a step-by-step Meta ads audit designed to optimize your ROAS and ensure your marketing dollars are working as hard as they should.
1. Understand What ROAS Means for Your Business
The first step of a Meta ad audit is to understand what “ROAS” actually means in your specific business context - not just what Facebook reports.
ROAS (Return on Ad Spend) = Revenue / Ad Spend
However, platform-reported ROAS doesn’t include cost-of-goods-sold (COGS), shipping, returns, or overhead. A reported 2X ROAS may imply you’re making money, but if your profit margins are slim or your customer return rate is low, you may be losing money overall.
Industry Benchmarks:
Average eCommerce ROAS: 2x to 4x (depends on product and AOV (average order value))
Subscription model (e.g., SaaS): 5x+ (depends on pricing, ROAS is LTV (lifetime value) driven)
Lead generation: Depends on LTV and close rate
Example:
For a fashion brand spending $100k/month. Facebook reported a 2X ROAS. But once COGS ($15), shipping ($6), and an average return rate of 20% were factored in, the true ROAS was closer to 0.9x.
Don't just audit what’s visible on the surface - dig into what matters for profit.
2. Step-by-Step Meta Ads Audit Framework (Campaign Review)
Once ROAS goals are clear, your first big audit area is the overall campaign structure.
Audit Questions:
Are campaigns aligned with clear objectives (Conversions, Lead Gen, Awareness)?
Is the setup based on ABO (Ad Set Budget Optimization) or CBO (Campaign Budget Optimization)?
Are campaigns being duplicated too frequently?
Best Practices:
Meta recommends fewer campaigns with clear objectives.
CBO is generally more efficient for scaling as the algorithm allocates budget to best-performing ad sets.
Aim for campaigns that can gather 50+ conversion events/week to exit the learning phase.
Red Flag:
If you’re running over 7 ad sets per campaign, with frequent campaign duplication, you’re fragmenting the data and confusing the algorithm. We’ve seen accounts with 13+ overlapping campaigns burning through budgets on the same audiences, causing ad fatigue without realizing it.
Recommendation:
Consolidate your campaign structure into:
Evergreen CBO campaign for scaling
Offer-based campaign (flash sales, product drops)
Lead generation campaign (if applicable)
Manage creative testing within isolated ad sets inside a master CBO instead of rebuilding campaigns weekly, which resets performance metrics.
3. Pixel and Tracking Validation
Poor tracking = poor optimization.
Pixel Audit Checklist:
Is the Facebook Pixel installed correctly on all conversion pages?
Are key events like Purchase, Add to Cart, View Content, and Initiate Checkout firing?
Is the Meta Conversions API (CAPI) integrated to compensate for browser tracking gaps?
Use the Meta Pixel Helper browser extension or Meta’s Test Events Tool to confirm whether both browser and server-side events are firing.
While many eCom brands still rely solely on browser tracking, 70% of consumers are blocking cookies online, according to research by Nano Interactive - underreporting key events post-iOS updates. Facebook has lost visibility into a large portion of user signals if no CAPI is present.
Why CAPI matters:
+8% average improvement in event match quality
Better attribution across devices and sessions
Improved custom audience generation
4. Audience Targeting & Structure Audit
Who sees your ads matters more than what they say.
Checklist:
Are you using custom audiences (purchasers, email list, website visitors)?
Have you created lookalike audiences (1%, 3%, up to 10%) based on most valuable customers?
Are your audiences too small or overlapping?
Are exclusions properly set up (exclude past purchasers in acquisition campaigns)?
Audience Segments to Analyze:
Cold/Warm: Lookalikes from high-LTV customers, interest-based audiences
Hot: Retarget Add-to-cart, View Content, and initiated checkouts
Retention: Target returning customers with 30-, 90-, and 180-day windows
Tool Tip:
Use the breakdown feature by region, age, and device to see which audiences are overperforming or underperforming.
When auditing, ensure each ad set has a distinct audience with minimal overlap.
5. Ad Creative & Copy Performance
Creative drives click-through rates (CTR), cost per result (CPR), and ultimately, your ROAS.
Audit Metrics:
CTR: Aim for 1%+ on cold audiences
Engagement Rate: Indicates if the creative resonates
Cost per Result (CPR): Is your message converting?
Creative Types to Test:
Static single images
Carousels (often 30-50% lower CPC)
Video (especially 9:16 for Stories/Reels)
User-generated content (UGC)
Dynamic creative with copy/headline/image variations
Congruence Is Key:
Your ad promise must align with your landing page. If your carousel promotes “Free Shipping on Orders $49+” but your landing page buries that offer, expect high bounce and poor conversion.
Tip:
Use Dynamic Creative Testing within a broad CBO for the cleanest data. Identify top winners and transfer their Post ID to other ad sets to maintain social proof.
Don’t over-analyze weak creatives—kill under-performers fast but make sure the data is of proper significance. Let data guide testing.
6. Landing Page & Conversion Path Analysis
Meta isn’t your only problem—you may be sending winning ads to broken pages.
Audit Items:
Mobile-first design (over 90% of traffic is mobile)
Page speed: Aim for <2.5s (use Google PageSpeed)
CTA placement—is it visible above the fold?
Messaging match—does the landing page headline mirror ad copy?
CRO tools like heatmaps (Microsoft Clarity) for behavior insights
Common Problems:
Slow mobile load: Increase in bounce rate, lower conversion
Visual bottlenecks: Poor CTA contrast or invisible CTAs
Message dissonance: Ad shows 25% off, but no clear mention on page
Improve ROAS by optimizing DPS (dollars per session):
Add urgency triggers
Use one-click offers or embedded upsells
Consider landing dedicated pages per offer/campaign
Example: A CPG brand reduced bounce rate by 23% just by improving mobile page speed and making their Buy 1 Get 1 Free offer sticky on scroll.
You paid to bring users to the page - don’t lose them with sloppy UX.
PS - A strong SMS sequence for post-acquisition or post-lead has over a 95% open rate and a 35% click through rate, compared with 20% and 2.5% for email marketing. See why we recommend Postscript here.
7. Attribution Model & Reporting Accuracy
Facebook uses a default 7-day click / 1-day view attribution model post-iOS 14. You can customize this, but inconsistent settings will skew performance data.
Audit Tips:
Align attribution models across campaigns for apples-to-apples measurement
For high-ticket or B2B, test longer attribution (7-day click)
For fast-moving eCom sales or flash offers, use 1-day click
Use both Meta reporting + GA4 UTM tracking to see the complete path. Meta tends to over-credit conversions; GA4 offers a more conservative view. Both have valuable insights they can provide.
Example:
By analyzing attribution across Facebook and GA4, one brand found their highest ROAS ads actually led to low session time and exits—indicating poor fit or misleading creative.
8. Set New ROAS Targets + Adjust KPIs
After the audit, you now have real insights to create smarter KPIs.
Set targets based on:
Breakeven CPA
Historical customer lifetime value
Marketing costs and fulfillment margin
Switch from ROAS to NC CPA:
New Customer Cost Per Acquisition > Platform ROAS
Focus on acquiring profitable, long-term customers, not just cheap clicks.
Create your own ROAS calculator:
Add COGS, shipping, fees, return %
Reverse engineer your max CPA
This becomes your “go/no-go” ad targeting rule
FAQs
What is a good ROAS for Facebook Ads?
Depends on your niche and margins, but most eCommerce stores target 2.5x–4x+. Calculate your breakeven ROAS first.
How often should I audit my Meta ad account?
Monthly for active advertisers; quarterly if you’re in maintenance mode.
Can I rely solely on Facebook Ads Manager for ROAS?
No. Facebook only tracks platform-attributed conversions. Add COGS, returns, and use tools like Triple Whale, GA4 for real numbers.
What attribution window should I use?
7-day click / 1-day view is standard. Test shorter windows for quicker sales cycles. Be consistent.
How can I reduce high CPA?
Improve creative relevance, tighten audience targeting, and audit landing page speed and congruence.
How do I check if my Pixel is firing?
Use Meta Pixel Helper browser extension, or Events Manager > Test Events tab.
Conclusion & Takeaways
If your Meta ads aren't delivering profitable performance, don’t assume it’s just competition or algorithm glitches. A structured Meta ad audit can uncover the hidden inefficiencies - whether it’s mismanaged campaigns, broken tracking, or misaligned landing pages.
ROAS is more than a platform metric. A solid, end-to-end audit gives you a realistic view of profitability, enables clear optimization steps, and ensures you scale what’s working sustainably.
