📌 What Is SEO?
SEO (Search Engine Optimization) is the process of improving your website’s visibility in search engine results pages (SERPs). When someone searches on Google, SEO helps your website appear at the top of the results for relevant queries.
In simple terms: SEO = getting your site noticed by Google so people can find you online.
💡 Why Is SEO Important in Digital Marketing?
Imagine opening a shop in a busy market—but without a signboard. Will anyone know you’re there? That’s what happens if your website isn’t optimized for search engines.
Here’s why SEO is vital in digital marketing:
✅ 1. Organic Traffic = Free Traffic
SEO brings visitors to your site without paying for ads.
✅ 2. Builds Trust and Credibility
People trust websites that appear on the first page of Google.
✅ 3. Increases Sales and Leads
More traffic = more chances of converting visitors into customers.
✅ 4. Long-Term Results
Unlike paid ads that stop when you stop spending, SEO works for months or even years.
✅ 5. Better User Experience
Good SEO also means a faster, mobile-friendly, and easy-to-navigate website.
