Quick answer

Instead of saying "link in bio," ask people to comment a keyword and send the link by DM. They get a tappable link without leaving the post, it stays in their inbox for later, and the comments count as engagement. Keep your bio link for general profile visitors.

Side by side

	Link in bio	Link by DM
Steps to the link	Leave the post, open profile, tap bio, find link	Comment one word, open DM
Right link for the post	Only if the bio page is up to date	Always, one link per post
Findable later	Bio changes over time	Saved in their inbox
Engagement on the post	None	Every request is a comment

When link in bio still makes sense

Your bio link is the front door for people who visit your profile. It's the right home for your main website or shop. For anything tied to one post, like a recipe, a product, or a limited offer, sending it by DM is simpler for the viewer.

Questions

What is the best alternative to link in bio?

Sending the link by DM. Ask people to comment a keyword on the post and an automation sends them the link directly, so they never have to leave the post to find it.
