Why adopting a customer-focused strategy is important in marketing?

The customer needs to understand what it is you're trying to sell. If you pitch your marketing strategy from a technical viewpoint and not what the customer wants to see, then you will turn potential customers away.

Use Apple as an example, they don't tell you about the processing speed of the chips, its Wi-Fi connectivity details, etc unless you specifically want to know. They promote, sexy, thin, ease of use, tons of apps, great colours... etc

Building a customer-focused strategy means understanding what makes valuable customers valuable. Customer focused strategies place the spotlight on the people that keep your product/service afloat and remain loyal toward them. 

Marketing is such a wonderful activity that is perform for Customers, aligns with Customer, and focused on Customer to stay prolong in the Market thus its important to have customer-focused strategy.
