What Threads actually allows
On your Threads profile you can add a link from the profile editor. Inside your posts, the URLs you write become clickable, which gives you more room than an Instagram bio. But at profile level you are still optimizing a single main slot.
Because Threads is tied to your Instagram account, most creators want the two to line up: same destination, same page under their own name, instead of maintaining two separate worlds of links.
Point your profile at a page that holds everything
Rather than dropping one raw link (your shop, say) and quietly ignoring the rest, put a link page address on your profile. It gathers your socials, your shop, your latest drop, your newsletter, your tip jar. You edit it whenever you want without touching your profile.
With Lynks.Pro that page is free: you pick lynks.pro/your-name, add your blocks, and paste the address into your Threads profile. The same page works on Instagram, which gives you one consistent destination across both.
Make the clickable posts work for you
Since URLs are clickable in Threads posts, use a clean short link when you share an offer: it reads better than a long URL and you get to count the clicks. A lynks.pro/xxx link looks more serious and tells you how many people actually tapped it.
Keep your link page as the permanent anchor on your profile, and use short links inside posts for one-off pushes. You get the stability of the profile and the speed of the feed.
