When you read blogs or browse websites, you’ll often click on words or phrases that take you to another page.
These are called links, and in digital marketing, they play a huge role in SEO (Search Engine Optimization) and user experience.
Let’s break it down in the simplest way possible.
🧩 What is a Link?
A link is just a clickable text or image that takes you to another web page.
There are 2 main types of links you’ll see on websites:
- ✅ Internal Links
- ✅ External Links
Let’s explore both with examples and why they matter.
🔍 What is an Internal Link?
An internal link takes you from one page to another within the same website.
📌 Example:
You’re reading a blog on your website and it says:
“Read more about our SEO services“
This link keeps the visitor on your site by taking them to another related page.
✅ Why Internal Linking is Important:
- Helps Google understand your website structure
- Keeps people browsing longer on your site
- Boosts SEO rankings for important pages
- Guides readers to related and helpful content

🌐 What is an External Link?
An external link sends the visitor from your website to a different website.
📌 Example:
“For more tips, check out this Beginner’s Guide to SEO on Moz“
This link leads to a trusted external source.
✅ Why External Linking is Important:
- Builds credibility – You’re showing helpful references
- Google sees you linking to reliable content, which helps SEO
- Improves user experience by offering more in-depth info
- Can increase chances of getting backlinks (when other sites link back to you)
