| Source | What you can inspect in Lemon | How to read it |
|---|---|---|
| Google Ads Transparency Center | Available text, image, and video previews; first and last shown dates; disclosed times-shown ranges and targeting fields | Lemon collects available ads overlapping the latest 90 days. A disclosed metric can cover a different country or period. |
| Meta Ad Library | Available creatives, copy, carousel media, delivery dates, platforms, and source-provided disclosures, including eligible EU reach estimates | Disclosure availability depends on region and ad type. Estimated account reach is not installs or revenue. |
| TikTok Commercial Content Library | Available video and image creatives, copy, delivery dates, disclosed unique-users-seen ranges, and targeting fields | Coverage is limited to the library’s supported countries. Potential audience describes targeting scope, not delivered reach. |
Missing metrics stay unavailable. Collection gaps and unreviewed matches remain visible. Ad counts, reach, and time in market can help you investigate a pattern; they do not establish competitor CPI, ROAS, or profitability.
For the source definitions, see Google’s advertiser transparency guidance, Meta Ad Library, and TikTok’s Commercial Content Library guide.
