Client Portfolio Review
Examining an agency’s client portfolio reveals the types of businesses they have served and their capability to handle projects similar to yours. Look for case studies, client testimonials, and industry diversity.
Important points to consider:
| Aspect | What to Look For |

Look for these reporting elements:
- Frequency of reports (weekly, monthly)
