- How are the strategies planned?
- How often are campaigns optimized?
Therefore, knowing how to choose a performance agency involves identifying those who operate in a structured way and not just reactively.
3. Is the strategy personalized or the same for everyone?
Performance doesn't allow for ready-made formulas. After all, an e-commerce business, a B2B company, and a local business, like a neighborhood gym, have completely different needs, sales cycles, and metrics.
A good performance agency starts by understanding your business, sales funnel, audience, and objectives before proposing any action. Therefore, be aware: if the proposal seems generic, the result will probably be too.
4. Does the agency understand your sales model?

- Where the money is being invested;
- Which campaigns perform best?

6. Does the agency work with continuous optimization?
Unlike one-off actions, performance is about constant improvement. A/B testing, creative adjustments, segmentation, and page optimization are all part of the routine.

- CRO (conversion rate optimization);

Modern performance depends on technology. Automation tools, data analytics, CRM, programmatic media and... artificial intelligence They are already part of the most efficient operations.
Agencies that use technology strategically are able to scale results with greater control and predictability. This is a clear competitive advantage.
9. Are there real-world case studies and evidence of results?
Well-constructed case studies show more than just numbers: they show the process, the challenges, and the lessons learned. When looking for a performance agency, analyze whether the agency can explain how it arrived at the results, and not just display graphs.
Remember: sustainable results are built with method, not luck.
10. Does the agency act as a partner or only as a supplier?
Finally, and perhaps most importantly: a performance agency doesn't execute tasks in isolation; it thinks collaboratively, questions decisions, and proposes improvements.
