To define measurable goals, follow the SMART criteria: 1. Specific: Clearly define what you want to achieve. 2. Measurable: Ensure the goal can be quantified. 3. Achievable: Set realistic targets. 4. Relevant: Align the goal with broader business objectives. 5. Time-bound: Specify a timeframe for achieving the goal.
Example: Instead of saying "increase email engagement," a SMART goal would be "increase email open rate by 15% in the next three months."
