Every time someone doesn't tap your link, it's rarely because they're not interested. It's because they don't know what's on the other side, and a mystery isn't a compelling enough reason to leave the feed they're comfortable in.
Tell them where it goes
'Link in bio' is a dead end of a phrase. 'Free pricing template in my bio' or 'shop the setup — link in bio' tells people exactly what they'll get for the tap. Specificity is what turns a scroll into a click.
Make the destination match
The link then has to deliver what the caption promised, immediately, without a hunt. If they were promised a template and land on a busy homepage, that's the last link of yours they'll trust.
