How to Create a QR Code for Your Link in Bio

A QR code for link in bio pages is a small bridge from the physical world to your phone-sized one. Someone sees your flyer, table card or product box, points a camera and lands on your page. Making the code takes about a minute. Most of the problems come afterwards, when a code has been printed and the address behind it changes.

What a QR code does here

A QR code stores text, and in this case that text is a web address. The phone’s camera reads the address and offers to open it. The code doesn’t know anything about your page, and it doesn’t update itself.

That makes it useful wherever a visitor can’t tap:

• Shop counters and table cards
• Flyers and posters
• Packaging and inserts
• Business cards
• Slides at a talk or workshop

If you’re already sending people to your page online, a QR code simply adds offline routes to the same place.

Static and dynamic codes explained

You’ll see these two terms when you search for a generator.

A dynamic code gives you flexibility, but your printed material now depends on that provider staying in business and on your account staying active. A static code has no middleman, but the address has to keep working.

BioFlow’s codes contain your page address directly, so they’re not dynamic. You can change what’s on the page at any time, and the code will show the new content, because the address hasn’t changed. What you can’t safely change is the address itself.

Creating one in BioFlow

Page QR

BioFlow is the page builder inside CommentLink, under Link in Bio. Once your page is published, its QR code is available from the dashboard. It leads to your page address, so it’s the right choice for general use, such as a counter sign that stays up for months.

Campaign QR

If you’ve created a named campaign, you can get a QR code for it as well. This one includes the campaign’s tags in its address, so that visits are attributed to that campaign. It’s the better choice when you want to compare, for example, a flyer with a shop sign.

Downloading the PNG

The dashboard downloads a 400-pixel PNG. Publish first, since the page has to be live.

Do the sums before you send it to print. At the 300 dots per inch that printers commonly ask for, 400 pixels covers about 3.4 cm across. That’s fine for a card or small sticker. For a poster, enlarging a small PNG can soften its edges, so ask your printer whether it’s acceptable. If it isn’t, paste the same address into a generator that exports vector files, and test the result.

Attributing visits with UTMs

BioFlow doesn’t count scans. A scan just looks like a visit to the page, so you’ll see it as a page view. To tell printed items apart, use campaign QR codes, each with its own tags. Their visits then appear with that campaign’s details in Campaign performance.

For a shop with a flyer and a table card, you might create:

This tells you which printed item brought more visits. It can’t tell you how many people looked at the flyer and didn’t scan. Our guide on tracking with UTM parameters goes into the idea in more depth. To see how this ties in with other channels, read about a cross-platform link strategy.

Printing and testing

A code that scans on your laptop screen may not scan on a shiny box in a dim shop. Keep these basics in mind.

• Leave a clear margin. DENSO WAVE, the company behind QR codes, says a code needs a four-module wide margin on all sides, with nothing printed there.
• Use strong contrast. Dark on a light background is the safest choice.
• Don’t stretch it. Scale it evenly, and keep it square.
• Test a printed sample. Try several phones, at the actual distance and in the actual light.

We go into materials and sizing in QR codes on product packaging and, for larger formats, in event posters and flyers.

QR errors found only after printing

These are the mistakes that hurt, because the fix is a reprint.

Changing your username. The address changes, the old address stops working, and BioFlow doesn’t redirect it. Every printed code then leads to a “not found” page.

Unpublishing the page. Taking the page down, even for a day, breaks every code until you publish it again.

Deleting the page. This is worse: it also removes the page’s blocks, events, leads and files, and unassigns its campaigns.

Testing the wrong file. Check the final artwork, not an earlier version. Designers sometimes swap in a placeholder.

Vague wording. “Scan me” rarely gives anyone a reason to. “Scan for today’s menu” does.

A page that doesn’t fit the moment. If the sign promises a menu, the top of the page should show the menu.

Before a big print run, decide on your username and leave it alone. For a small shop, this is one of the first steps worth taking, and our guide to link in bio for small business covers what should be on that page.

FAQ

How do I make a QR code for my bio link?

Publish your page first. In BioFlow, the dashboard gives you a QR code to download as a PNG, either for the page or for a named campaign. You can also paste your address into any QR generator. Whichever you use, print a sample and test it on more than one phone before ordering.

Can I change where it points?

Not with a static code, as the address is stored in the code itself. You can change the page’s content freely, since the address stays the same. Dynamic codes from a provider can be redirected, but they depend on that provider. Renaming your BioFlow username breaks existing printed codes, because the old address isn’t redirected.

Can I track scans?

BioFlow doesn’t count scans directly, because a scan looks like an ordinary page view. Using a campaign QR code adds tags to the address, so those visits appear under that campaign. If you need true scan counts, look at a dynamic code provider, keeping in mind that you’d then depend on it.

Print one, then test it

Publish your page, download a code and print it on plain paper. Scan it from across a table, then in the place it’ll actually live. If everything works, order your print run. You can generate a QR code in BioFlow, and the features page shows what else comes with it.
