Introduction
SEO in Digital Marketing has become essential in today’s fast-paced online world. Businesses thrive on visibility. Whether you run a small store or a multinational brand, having a strong online presence with SEO is no longer optional—it’s fundamental. And that’s where Search Engine Optimization (SEO) comes in.

What is SEO?
SEO (Search Engine Optimization) is the practice of optimizing your website to improve its visibility on search engines like Google, Bing, and Yahoo. When someone searches for a product, service, or information vital to your business, SEO helps your website appear at the top of the search results.
👉 Without SEO: Your website is like a shop hidden in a dark alley.
👉 With SEO: Your shop is on the busiest street, with thousands of people passing by daily.
The objective of SEO is not just to bring traffic but to bring relevant traffic—visitors genuinely interested in what you offer.
