What to actually watch, not just collect: * **Longevity:** Which creatives survive for months? These are likely the real winners. * **Format and angle rotation:** How do brands package the same offer using different hooks, formats, and creative angles? * **Offer and price changes:** Track how the offer, pricing, and messaging evolve over time. **Scaling it:** If you're technical, the Ad Library API can pull creatives in bulk. Pair it with a screenshot service to capture the landing page side as well. Once the manual sweep becomes time-consuming, this is exactly what competitor-tracking tools automate. They continuously tag competitors' ads by creative attributes, identify long-running winners, and highlight gaps against your own creative library. That's the category worth exploring if this becomes a weekly time sink.
