Introduction
Digital marketing has become the engine that powers modern businesses.

What is Digital Marketing?
Digital marketing refers to all online strategies used to promote products, services, or brands through the internet. It includes multiple channels that work together to drive visibility, engagement, and conversions.

SEO focuses on ranking websites higher on Google and other search engines.
Key SEO components include:

Short-form video content is currently the fastest organic traffic generator.
4. Email Marketing
Email marketing remains one of the highest conversion channels.
Benefits:

A well-built email list can turn a small blog into a profitable online business.
