Account-Based Marketing (ABM) is a strategy focused on selling to specific accounts rather than a mass audience. Instead of broadcasting messages to everyone, ABM personalizes campaigns for key companies or clients with specialized content, advertisements, and follow-up. It is widely used in B2B sales, where buying cycles are long and potential clients are high-value. Tools such as HubSpot, Salesforce, and LinkedIn Sales Navigator help implement ABM strategies with automation and data analysis. It is an efficient way to close deals with strategic clients.
