What is a link in bio? How to create one for free

TikTok, Instagram and Facebook let you add only one link to your profile. Yet you have many things to show: products, prices, a Zalo number, reviews, a store address. A link in bio exists to solve exactly that.

What is a link in bio?

A link in bio (also called a bio link) is a small, fast-loading web page with a single address. You put that address in your profile. Anyone who taps it sees a list of buttons and content blocks you arranged yourself, such as a Zalo button, a products button and a directions button.

How is it different from a regular website?

• It is a single page designed for phone screens first, because visitors from social networks are almost all on phones.
• You build it in minutes by picking a template and replacing the text, photos and prices. No hosting to buy, nobody to hire.
• Its one job is to get a visitor to do one thing: message you, call, leave a phone number, or browse your goods.

What should go in a link in bio?

• One line about you: what you sell, where, and for whom.
• The main action button at the top, usually messaging on Zalo or calling.
• Your 3–6 best-selling products or services, with photos and prices.
• A field to leave a phone number for visitors not ready to message yet.
• A few real reviews from past customers, if you have them.

• No real photos or prices. Vague pages do not get messages.
• Not checking on a real phone before putting the link in your bio.
