Choosing the right customer acquisition channels can determine whether your business grows efficiently or struggles with high costs and inconsistent results. With so many options available, it’s easy to spread resources too thin or invest heavily in the wrong places.

This article breaks down the best customer acquisition channels, how they work, their strengths and weaknesses, and when each channel makes the most sense for your business.

The wrong channels:

• Waste budget

• Attract unqualified leads

• Create inconsistent growth

• Increase churn

Strategic channel selection is a competitive advantage.
