Lead Qualification

Most agencies qualify leads using models like BANT (Budget, Authority, Need, Timeline) or similar frameworks. Leads are filtered by factors such as company size, role, location, and buyer signals like email engagement or call bookings. This improves conversion rates and sales efficiency.

Local vs National Agencies

Local agencies tend to offer more tailored support, better flexibility, and stronger regional knowledge.
National agencies often have larger teams, broader reach, and more advanced tech stacks.
The right choice depends on your campaign goals and business model.
