Founder guide
The library shows creative activity, not campaign economics.
For commercial iOS apps, Meta Ad Library is useful for advertiser identity, creative, copy, start date, status, platforms, and destination context. It does not provide the ROAS, CPI, installs, revenue, or exact spend needed to declare a winner.
What you can and cannot see
| Useful public evidence | Not public for ordinary commercial app ads |
|---|---|
| Advertiser/page identity | Exact spend |
| Creative and primary text | Revenue or ROAS |
| Start date and current status | Installs or subscriber conversions |
| Placements shown by Meta | CPI, CPA, retention, or payback period |
| Destination link when available | Audience targeting details |
Use language that matches the evidence
| Avoid | Use instead |
|---|---|
| Best-performing ad | Long-running ad observed on this date |
| High-spend creative | Creative with several grouped variants |
| Proven winner | High-priority creative for qualitative analysis |
| This hook converts | This hook recurs across the observed set |
Triangulate before you spend
Pair public-ad observations with App Store positioning, customer-review language, your own campaign data, and a dated source record. The library is excellent for generating hypotheses. Your account is where those hypotheses become evidence.
