If you've ever searched for a product online, clicked on a sponsored ad, or followed your favorite brand on Instagram, you've already interacted with digital marketing—whether you realized it or not.

In today’s digital-first world, businesses can no longer rely on traditional marketing alone. Digital marketing is the backbone of modern brand visibility, customer engagement, and online growth.
