FIX LIBRARY · Meta
Meta ads fix library.
Twelve of the problems that cost the most money, each explained at the mechanism level: what is actually happening inside the auction or the algorithm, why the obvious fix often makes it worse, and what to do instead.
Written by Jonas Sluijs, former Meta growth lead, $500M+ in ad spend.
Every fix guide
- Advantage+ Campaign Is Underperforming Advantage+ Shopping Campaigns (ASC) promise automation and performance. When they underperform, it is almost always one of three structural problems -- not a sign the product does not work.
- Cost Cap vs Bid Cap: Which Should I Use? Manual bidding is frequently recommended as a solution to high CPA. It is often the cause of new problems. Understanding when it applies and when to leave it alone prevents most manual bidding mistakes.
- CPM Increased Sharply: What Is Happening? CPM is the variable most advertisers try to control and the one they have the least direct influence over. Understanding what actually sets it tells you which responses are productive and which make things worse.
- How to Scale Meta Ads Without Killing Performance Scaling Meta ads is not one decision -- it is a sequence of decisions with specific order and timing constraints. Most scaling failures come from moving too fast or skipping steps.
- How Do I Write Meta Ad Copy That Converts? Ad copy does not sell -- it creates enough relevance and trust to earn a click. The structure that achieves this consistently is simple. Most ads fail because they lead with the wrong element.
- How iOS 14 Changed Meta Ads and What You Can Do About It iOS 14 changed Meta advertising permanently. Most of the practical adjustments were made at the platform level years ago -- but many advertisers are still missing the account-level fixes that recover most of the lost performance.
- Meta Ads Attribution: How It Works and Why Numbers Look Inflated Meta's attribution model is one of the most misunderstood parts of the platform. Understanding it does not just explain the discrepancy with your CRM -- it changes how you evaluate campaign performance.
- How to Run Meta Ads for E-commerce E-commerce is the most data-rich Meta advertising environment and the most competitive. Getting the foundation right determines whether the rest scales. For the configuration itself, objective, ASC versus manual, catalogue and scaling rules, use the Meta ads ecommerce setup tool.
- Why Do Meta Numbers Not Match My CRM? A discrepancy between Meta-reported conversions and your CRM is expected and normal -- up to a point. Understanding the mechanism tells you when to investigate and when to accept the gap.
- Should I Use Video or Static Image Ads? Video outperforms static in benchmarks. Static outperforms video in most individual accounts. The discrepancy is execution -- and understanding it tells you what to actually test.
- What Is Meta CAPI and Do I Need It? CAPI is not optional if you are serious about Meta advertising. Since iOS 14, browser-only tracking loses a meaningful share of conversion signal by default. CAPI recovers it.
- Why Did My CPA Increase Suddenly? CPA increases are one of the most common panic moments in Meta advertising. The account was working, now it is not. Before touching anything, understand what actually drives CPA and where the breakdown most likely is.
