First, confirm the agent is active and its LinkedIn account is connected and healthy. New agents normally begin discovery within a few minutes after activation, but results arrive gradually because ProspectHalo uses conservative account-level limits.
Then review the targeting. A very narrow combination of role, industry, location, company size, and extra requirements can exhaust the available LinkedIn audience. Start with a focused buyer role, relevant industries, and target locations, then let ProspectHalo explore related titles and search angles within your saved ideal customer profile.
Also remove conflicting included and excluded titles. On standard LinkedIn accounts, some advanced filters may not be available. If the setup still looks correct, contact support with the agent name so the resolved search filters can be checked.
