Every creator ends up needing a link-in-bio tool eventually, but most comparisons stop at layout templates and ignore the thing that actually matters once you're negotiating brand deals: the data behind each click.
What most tools get right
The major link-in-bio platforms all handle the basics well: a mobile-friendly landing page, multiple links, and simple customization. At the free tier, they're mostly interchangeable.
Where they differ
Click-level analytics: some tools show only totals, others break down by link, referrer, and time
Custom domains: needed if you want the bio link to match your brand instead of a platform subdomain
Data ownership: whether you can export click history for media kits and brand reporting
What to prioritize
If you're early and just consolidating links, any tool works. Once you're pitching brands, the analytics depth becomes the deciding factor, since "trust me, it gets clicks" doesn't close deals the way a real click report does. Look for tools built around tracked links with per-link scan and click data, not just a page view counter.
