When you're vetting an agency, the number one question should always be related to their track record for success. Here are some factors to keep in mind: Data: Ability to read between the metrics and extract value-based insights. Curiosity: Obsessive interest towards how the work contributed to organizational objectives. Accountability: Stepping up and bouncing back from misguided strategies. Effectiveness: Ability to replicate performance wins and bottom line traction across initiatives.
