Before signing any contract, clarity on the following will save time and budget:

• I wonder what success looks like after ninety days. Success should be defined by a milestone, not a vague promise.

• I ask, who actually works on your account? Some agencies advertise talent but the work on your account is done by junior staff.

• I want to know how performance is reported. Ask for sample reports. Look for revenue and lead data, not traffic numbers.

• I ask, do they have experience, in your industry? Industry experience shortens the learning curve significantly.

• I ask, what does the contract exit look like? Flexible agreements signal an agency that earns retention through contract results.
