How smart link routing works

Smart link routing is what makes PostLink different from a standard link-in-bio tool.

The traditional approach: With tools like Linktree, your bio link leads to a page with a list of links. Followers have to scan the list and find the right one. Most don't bother — they bounce.

The PostLink approach: PostLink knows which Instagram post a follower just viewed. When they tap your bio link, PostLink automatically redirects them to the article linked to that specific post. No list. No searching. One tap, right content.

How it works technically: 1. When you link an article to an Instagram post in PostLink, we store that association. 2. When a follower taps your bio link from Instagram, PostLink receives referral context about which post they came from. 3. PostLink looks up the linked article and redirects the follower there instantly (sub-200ms). 4. If no matching post is found, the follower sees your PostLink profile page with all your linked content.

This means: - 80% of followers reach the right content (vs. 20% with link walls) - Your content gets 4x more clicks from the same number of bio taps - You never have to update your bio link — it routes automatically

Smart routing works with Instagram today. TikTok support uses a similar approach optimized for TikTok's referral patterns.
