How to set up your social profiles for your SaaS or app

When someone likes a post of yours, the next thing they do is tap your name. What they find there decides whether they follow you, open your link or leave. This guide is about that page: what to put on a profile so a visitor understands in a few seconds what your product does and what to do next. It covers Instagram, TikTok, X and LinkedIn, and it sticks to what each platform says itself.

Will a visitor understand what I do?

A profile is a very small landing page. It has a picture, a name, a few lines of text, a link and a handful of posts you choose to show first. Posts bring people in, and the profile is where they decide. If the profile says nothing about your product, the best post in the world has nowhere to send anyone. If you are still working on the posts, start with how to market your app on TikTok, then come back here.

The five parts of a profile

The same five parts work on every platform. Only the names change.

1. A clear picture. Your logo or a plain portrait on a solid colour. It is shown very small, so one subject and strong contrast beat detail.
2. A name that says what you do. Your product or your own name, followed by the word a customer would type into search, for example “Ana | invoicing for freelancers”. Pick words you would be happy to be found by.
3. A bio with three parts. What the product does, for whom, and the next step. Write it for someone who has never heard of you.
4. A link. One link, to the page that matches the next step you wrote in the bio.
5. Posts that explain you. Where the platform lets you pin or feature posts, use those spots for the posts a newcomer needs, not the ones that happened to be seen most.

Instagram

Instagram says how its search works. In its post “Breaking Down How Instagram Search Works”, it explains that search results are matched by text, and recommends a handle or profile name related to what you post, keywords and a location in your bio, and keywords in captions rather than in comments. That is the reason to put your niche in the name field and not only your name.

• Name field: your name, then what you do. The handle stays short and easy to say.
• Bio: the three parts from above, with your main keyword in the first line.
• Highlights: the product in use, how you work, and where to start. Group them by the question a visitor has, such as “How it works” or “Start here”.
• Pinned posts: Instagram’s help center says you can pin up to three posts to the top of your profile. A good set is one that explains what the product does, one that shows a real customer problem solved, and one about why you built it.

TikTok

On TikTok the profile sits behind the posts, so a visitor usually arrives from one of them and wants to know if there is more like it. Keep the bio short, say who the product is for, and add your link where the app lets you. Check the current limits in the app’s edit screen rather than relying on a number you read somewhere, because they change. If you publish photo posts, keep the first few consistent in look and topic, so a visitor sees a clear idea of what you post about. How to make a TikTok photo carousel covers making them.

X

X lets you pin one post to your profile so it is the first thing people see, and its help center says a bio over 160 characters will not save (see how to customize your profile). With one slot, pin the post that explains your product to a stranger. Rotate it when your offer changes.

LinkedIn

On LinkedIn, the headline, the About section and Featured do the work of the bio, the link and the pinned posts. LinkedIn’s own profile guidance says About should express your mission, motivation and skills. For a founder, that means: write the headline as what you build and for whom instead of only a job title, use About to say what problem the product solves and what you do next, and use Featured for a demo, a customer story or the page you most want people to read.

A bio you can copy

Fill in the three parts, keep it plain, and leave out anything you cannot show:

• Line 1, what and for whom: “Invoicing for freelance designers.”
• Line 2, one true fact: “Free to try. Built by one person.”
• Line 3, the next step: “Start here ↓”

Replace each example with your own, and only use a result or a number if you can point to where it comes from.

Checklist

• The picture is readable when it is tiny.
• The name contains what you do, not only who you are.
• The bio says what, for whom and what next.
• There is one link, and it matches the bio.
• The pinned or featured posts explain the product to someone new.

Platform features change. This guide was checked against the sources above on 29 October 2026, so if a screen looks different in the app, trust the app.
