What is Links and How Many Types of Links
Links are the invisible threads that hold the web together. Every time you click on a word, an image, or a button and land on another page, you’re using a link. Without them, websites would be nothing more than isolated documents with no connection to one another. Links allow us to move fluidly across the internet, they guide search engines to discover and rank new pages, and they shape how users experience a website.
In this comprehensive guide, we’ll explore what links are, the different types of links in websites, types of links in SEO, and frequently asked questions about linking. Each section includes HTML examples to help you understand how links are implemented in real-world situations.

A link (short for hyperlink) is a clickable element on a web page that takes you to another destination. That destination could be another web page, a section of the same page, a downloadable file, an email address, or an external website.
Links are created with the HTML <a> tag, also known as the anchor tag.

Types of Links in SEO
From an SEO perspective, links are not just navigation tools—they’re ranking signals. Google and other search engines rely heavily on links to evaluate authority, trust, and context.

NoFollow Links
A nofollow link includes the rel="nofollow" attribute, telling search engines not to pass authority.
Example:

Example:
UGC (User Generated Content) Links

Final Thoughts
Links are more than just pathways between pages—they’re the framework of the web and a critical ranking factor in SEO. Every type of link serves a unique purpose:
- Text and image links guide users visually.

- External links show trust and research.
- Anchor links improve navigation.
