Almost every guide on customizing a link in bio page ends the same way: open the editor, change the background color, upload your logo, done. That's decoration, and decoration rarely changes how many people click. This guide covers the decisions that do — what shows first, how many links fit before they start competing with each other, what your buttons are called, and what each visitor should see — because those are what separate a good-looking page from one that converts.

Short answer

Customizing a link in bio page happens at three levels: appearance (color, type, logo), structure (which links, in what order, with what labels) and behavior (what each visitor sees based on who they are). The first is the most visible and affects results the least. The third is the one almost nobody touches.

The three levels of customization (only one moves the numbers)

When someone searches for how to customize their bio link page, they're almost always thinking about the first level. It's worth separating all three before you touch anything, because the effort each one takes and the return each one gives are very different.

Level 1 — Appearance. Colors, type, logo, background image, button shape. Every editor offers this and you can finish it in ten minutes. It matters, but for one specific and limited reason: the page should look enough like your profile that nobody wonders whether they landed in the right place. Once that's true, another pass on the gradient buys you nothing.

Level 2 — Structure. How many links, in what order, with what text, which one stands out. This is where clicks are won or lost, and it's the part most people inherit from a template without thinking about it. Four sections of this guide go here, because this is where the return is.

Level 3 — Behavior. The page isn't the same for everyone: it asks something and adapts, or shows one thing to someone arriving from TikTok and another to someone arriving from your newsletter. Almost no link-list tool allows this, which is why almost nobody counts it as "customization." It is, and it's the level that changes the numbers most.

If you're starting from scratch and don't have a page to customize yet, start with what link in bio means and come back here.

Start with what shows before anyone scrolls

Your link in bio page lives behind a link inside a mobile app. That means practically all your traffic arrives on a phone, in Instagram's or TikTok's in-app browser, with the top of the screen already taken by the app's chrome and the bottom by system controls.

The real space you have before the first scroll is smaller than what the desktop editor shows you. And that's where most of it is decided, because a meaningful share of visitors never scroll at all.

What belongs in that first screen:

Who you are — photo or logo and one line confirming it. This is the "I'm in the right place" check.
What you offer — one sentence, not a paragraph. "I help coaches fill their calendar" says more than "Welcome to my official page."
The primary action — one button, the one you actually want tapped.

What does not belong up there: a row of social icons. It's the most repeated structural mistake there is. You just got someone to leave Instagram, and the first thing you offer them is a way back to Instagram.

The five-second test

Open your page on your own phone, from the link in your bio — not from the editor. Look at it for five seconds and close it. If you can't say out loud what you wanted the visitor to do, your first screen isn't solved, and no color change is going to fix that.

How many links to include: the ceiling almost nobody respects

The temptation is to include everything: the site, the shop, the podcast, the latest reel, the contact form, all five social accounts. What you get is a list where nothing stands out, and a visitor who — facing too many equivalent options — picks none of them.

A rule that holds up in practice: three to seven links, with one clear protagonist. Past seven, each new link takes more attention away from the ones you already had than it contributes on its own.

To decide what stays, rank your links by what they actually return, not by what they cost you to make:

Link type	Does it go up top?	Why
The action that produces revenue or leads	Always	It's the reason the page exists
Recent content you're actively promoting	Yes, while it's current	It expires — pull it when it does
Catalog, services, "about me"	Middle	Sought out by people already interested
Other social accounts	Bottom, or not at all	Sends the visitor back where they came from

If applying this leaves you with two links, that's fine. A two-link page with the right two links outperforms a twelve-link page.

How to write your button labels

This is the highest-return-per-minute part of customization, and the part most people leave exactly as the template shipped it.

The rule is simple: the button should say what happens on the other side. When the label and the destination don't match, the visitor finds out after clicking, and that mismatch is the most expensive way to lose someone who had already decided to move forward.

Concrete comparisons:

❌ "Click here" → ✅ "Book a 15-min call"
❌ "Learn more" → ✅ "See the full program"
❌ "Link" → ✅ "Download the free guide"
❌ "My shop" → ✅ "Buy the course (instant access)"
❌ "Contact" → ✅ "Message me on WhatsApp"

Three tests to run on every label you have right now:

Start with a verb. "Book," "Download," "Watch," "Buy." A bare noun ("Newsletter") names a category; a verb names an action.
State format or cost when it drives the decision. "15-min call" and "12-page PDF" remove the hesitation that stops the tap. If something is free, say so.
Make it make sense out of context. Whoever lands here hasn't read your last post. "The method I explained Tuesday" means nothing to most of them.

Don't guess which label works — test it

Labels are the cheapest thing to change and the easiest to measure, which makes them the ideal A/B test candidate. Changing only a button's text and comparing over two weeks is a clean test — see how to set one up in the bio link A/B testing guide.

Visual hierarchy: pick exactly one primary button

If every button is the same color, the same size and the same weight, you're asking the visitor to read and decide. Most won't. They'll leave.

Hierarchy means one button looks different on purpose. The primary one takes your accent color and a solid fill; the rest get outlines or a muted tone. One clear visual difference is enough — you don't need a three-tier system.

The question that settles all of this: if the visitor tapped only one thing on the entire page, which should it be? That's your primary button. And there can only be one — the moment you emphasize two, you're back to emphasizing neither.

One detail that gets missed: hierarchy is positional too. The primary button belongs on the first screen, not at the end of the list. It's common to see pages where the booking link — the only one that produces revenue — sits seventh, below three social accounts.

Color, type and contrast: look like you and stay readable

Now for level 1. The goal here isn't a pretty page, it's a recognizable and readable one.

Recognizable. Use the same colors and tone you already use on your profile and in your content. The visitor is arriving straight from your feed; if the page looks like someone else's, there's a beat of doubt you don't need. Two colors and one typeface are plenty. Three different typefaces don't customize more, they just look like a badly edited template.

Readable. This is where good-looking design actually breaks pages. The patterns that fail most often:

White text over a light background photo: unreadable the moment there's sun on the screen.
Light gray on white: looks perfect on your monitor, disappears on a phone at 40% brightness.
A decorative typeface on buttons: hard to read exactly where reading needs to be instant.

The check is the same as always and needs no tooling: open the page on your phone, at low brightness, outdoors. Whatever isn't readable there isn't readable.

A note on dark mode: plenty of people browse with their phone in dark mode, and in-app browsers honor it inconsistently. If your tool previews both, look at both before calling the page done.

Your URL and your preview image are customization too

Two elements nobody counts as design, both as visible as everything else.

The URL. sellb.io/yourname says something different from sometool.com/u/48219x. It's what people see in your bio before deciding whether to tap, and what shows up when someone recommends you in writing. A clean URL with your name on it is among the cheapest customizations available — covered in depth in what a vanity URL is.

The preview image. When someone shares your link over WhatsApp, Telegram or DM, they're not sharing your page — they're sharing a card with an image, a title and a description. If you never set it, that card goes out with the generic logo of whatever tool you use, and a customer's recommendation arrives carrying someone else's brand. Check yours by messaging the link to yourself before you call it finished.

The level almost nobody uses: a page that changes per visitor

Everything above still assumes one page, identical for everyone. That's the underlying limit of link-list tools, and it's why so many pages end up as a compromise — trying to serve both the person who already knows you and wants to buy, and the person who just arrived and doesn't know who you are.

The way out of that compromise isn't better design, it's to stop treating those two the same. Instead of a list, the page asks a question — "what brings you here?" — and shows one thing or another based on the answer. Someone who says "just getting started" sees the free guide; someone who says "I want to work with you" goes straight to the calendar. Each gets a shorter, more relevant page than the one you'd have designed for both.

That's conditional logic, and it's the practical difference between a link list and a flow. It's also why coaches — who get messages from people at wildly different stages, from curious to ready to buy — stop trying to sort that mix into a single list. If you're comparing which tools allow this and which stop at visual customization, the Linktree alternatives comparison and SellBio vs Linktree break it down.

Common customization mistakes (and how to catch them)

Designing on desktop and never checking on mobile. The editor shows you a wide window; your visitors see a narrow column inside another app. Everything you decide on a big screen needs confirming on a small one.

Leaving expired links up. The launch that ended, the March webinar, the "coming soon." A page with stale content reads as neglect, in the one place you can't afford it. Put a monthly reminder on your calendar to walk through it.

Changing five things at once. If you redo the colors, reorder the links and rewrite the labels in the same afternoon and clicks go up, you don't know what worked — so you can't repeat it. Change one thing, give it two weeks, measure.

Customizing without measuring anything. This is the mistake that makes all the others pointless: without knowing which button gets tapped and which doesn't, every decision here is an opinion. Any serious tool gives you per-link clicks on the free plan; how to read those numbers is in the link in bio analytics guide.

Customizing your link in bio page has less in common with decorating than with editing: most of the good work is removal. Fewer links, one primary button, labels that state exactly what will happen, and a first screen that reads in five seconds. Once that's settled, the next jump isn't visual at all — it's to stop showing everyone the same thing. For the rest of the setup and strategy around the page, the complete link in bio guide covers the full path.
