What is a link in bio form?
A link in bio form is a short form placed on, or one tap from, the page your social profile links to, so visitors can book, enquire or sign up without leaving. To add one, pick a single offer, build a three-field form, put it on your bio page and make sure each submission keeps the platform and post that sent it.
- Choose one offer worth filling a form for.
- Put a short form on your bio page.
- Keep the source on each submission.
- Follow up fast.
Your profile sends visitors to the bio page, the form creates a lead with the platform and post attached, you follow up, and won deals are reported by source.
Why forms beat link lists for coaches and businesses
A link list is a menu. People tap, leave, and you never learn who they were. For a creator selling merch that can be fine. For a coach, consultant, clinic or agency, the visit is only worth something if it turns into a conversation.
| Link list | Bio page with a form | |
|---|---|---|
| What you get | A click count | A named lead |
| Can you follow up? | No | Yes |
| Do you know the source? | Sometimes, if links are tagged | Yes, if the form keeps it |
| Good for | Sending traffic elsewhere | Bookings, enquiries, waitlists |
What makes a good bio form
- One offer. "Book a free intro call" beats "Contact me".
- Three fields or fewer. Name, email, one question.
- A clear next step on the thank-you screen: a calendar link or what happens next.
- The source kept on the lead. Without it you can't tell whether TikTok or LinkedIn filled your calendar.
How to add a form to your link in bio
- Pick your form tool and create a short form.
- Add hidden fields for
utm_source,utm_medium,utm_campaignandutm_content, set to fill from the URL. - Tag the link in each profile with the UTM builder, one
utm_sourceper platform. - Embed the form on your bio page, or link a card straight to it.
- Make sure the tags reach the form. If the visitor moves from the bio page to the form, the page has to pass the UTMs along.
- Submit a test lead from inside each app and check the source.
Don't want to wire hidden fields yourself? Pre-register for Trakt and the source is captured on every form automatically.
Illustrative examples
These are made-up examples to show the shape, not real accounts.
- A fitness coach swaps a six-link list for one "Apply for coaching" form. Each application arrives tagged with the platform.
- A wedding photographer puts an availability form on the bio page. Enquiries from Instagram and TikTok are split by source, so she knows where to post.
- A B2B consultant links his LinkedIn profile to a "Book a strategy call" form, tagged
utm_source=linkedin.
Why manual bio forms break in practice (and how Trakt helps)
Hidden fields are fiddly. They break when a page is rebuilt, and a form embedded one page away from the bio link often loses the tags on the way.
How Trakt closes the gap
With Trakt you can build forms in Trakt, or let Trakt find and track the forms already on your site; either way the hidden UTM fields are added automatically. Trakt Sites gives you the bio page, every lead it brings in arrives with its source attached, and you get a new-lead alert by email and Slack. See Trakt forms for the form side. Leads and revenue sync into your CRM.

| Form | Any form tool | Built in Trakt, or your existing form |
| Source on submission | Hidden fields you maintain | Added automatically |
| Lead alerts | Per tool | Email and Slack |
| A good offer | Same either way | Same either way |
FAQ
Can I put a form in my link in bio?
Yes. Either embed a form on the page your bio links to, or point a card straight at a form page. Keep it short and give it one clear offer, such as booking a call.
Is a link in bio form better than a list of links?
For service businesses, usually yes. A list sends people elsewhere and you learn nothing about them. A form gives you a lead you can follow up, and with tagged links it tells you which platform sent them.
How do I know which platform a bio form lead came from?
Tag the link in each profile with its own utm_source, then make sure the form stores those values in hidden fields or captures them automatically. Test each platform from inside its app.
What fields should a link in bio form have?
As few as you can: name, email and one qualifying question. Every extra field costs submissions. Add the UTM values as hidden fields so the visitor never sees them.
Which link in bio tool has built-in lead forms?
Trakt Sites works with forms built in Trakt, and every lead arrives with its source attached. That gives you leads by platform on the dashboard, not just clicks.
What to do first
Write down the one thing you want profile visitors to do. Build a three-field form for exactly that, tag your bio link per platform, and send yourself a test lead from each app. Then replace the link list.
