Designers, photographers, and other creatives usually have their work spread across several platforms - Behance, Dribbble, Instagram, a personal site. A portfolio link-in-bio page ties all of that together so someone clicking your bio link can see your work and know how to reach you, without clicking through multiple tabs.
What to include
You do not need to reproduce your full portfolio on this page - just enough to orient someone and send them to the right place. A name and a short tagline ("Freelance brand designer - London"), a photo or a hero image of your best work, link buttons to your Behance, Dribbble, or main portfolio site, and a contact link or email button. That is usually enough.
If you do client work, consider adding a brief note about what kind of projects you take on. It saves a round of emails later.
Building the page
Use OMIU to add a text block for your name and tagline, an image block for your photo or a portfolio preview, then link blocks for Behance, Dribbble, your website, and a contact option. Add social icons if you are active on Instagram or LinkedIn and want people to follow you there.
The page is mobile-first, which matters since most bio link clicks happen on a phone. Keep labels short and make sure your most important link is at the top.
Adding it to your social profiles
Save your profile and you will get a URL like omiu.me/yourname. Paste it into your Instagram bio, Twitter/X profile, and LinkedIn. When you update your portfolio or want to add a new platform, edit your OMIU page - you do not need to change anything on your social profiles.
Should I use this instead of a full portfolio site?
Use it alongside your portfolio, not instead of it. The link-in-bio page is the front door - it introduces you and directs people to your full work. If you do not have a full portfolio site yet, linking to your Behance or Dribbble from here works fine in the meantime.
