Meta Ads Manager uses dozens of terms that aren't obvious — even to experienced marketers. What's the difference between Reach and Impressions? What does Campaign Budget Optimization actually do? When Meta says "Relevance Score," what are they scoring?
This glossary answers all of it. Every definition is written to be understood on the first read, without needing to look up three other terms to make sense of the first one.
- ✓ Confused by the difference between Custom and Lookalike Audiences? Both are defined with clear explanations of when to use each one and how they work together in your campaign structure.
- ✓ Not sure what Campaign Budget Optimization changes? The glossary explains how CBO shifts budget allocation from the ad set level to the campaign level — and why that matters for your results.
- ✓ Want to understand attribution in Meta Ads? The attribution entry covers click-through vs view-through windows, default settings, and how Meta counts conversions differently than Google.
- ✓ Struggling with bid strategy options? Each bid strategy type is defined separately so you can compare them without switching between help articles.
- ✓ Need a quick reference during client calls? The alphabetical format means you can find any term in seconds — no scrolling through paragraphs of context you don't need.
