What Is a Smartlink? How AI Traffic Routing Works in Performance Marketing

By SortExpress Team  ·  5 min read

A smartlink is a single URL that sits between your ad and your landing pages. Instead of taking every visitor to one fixed page, a smartlink evaluates each visitor in real time and routes them to the landing page most likely to convert them — based on their keyword, location, device, and behavior patterns.

The idea is simple: not every visitor is the same, and the best landing page for one visitor may be the worst for another. A smartlink uses data to make that decision automatically.

The Problem Smartlinks Solve

Most PPC campaigns send all traffic to a single destination URL. Even when advertisers build multiple landing pages, they typically assign them manually by campaign or ad group — which misses the interaction between dozens of visitor parameters.

For example, a visitor searching "emergency plumber" on a mobile phone at 11pm in a big city is a completely different conversion opportunity than someone searching "plumbing services cost" on desktop on a Tuesday afternoon. They need to see different landing pages. Manually routing for every combination is impossible.

How a Smartlink Works — Step by Step

Visitor clicks ad Smartlink receives request AI scores all landing pages Visitor lands on best page

In under 10 milliseconds, the smartlink:

  1. Reads the visitor's parameters: keyword, country, city, device, browser, OS
  2. Looks up historical conversion data for visitors with matching parameters
  3. Scores each of your landing pages based on past performance for this profile
  4. Routes the visitor to the highest-scoring page — or a random page if there's no data yet

As more visitors convert, the AI accumulates data and makes better decisions. The system improves continuously without any manual intervention.

What Parameters Does a Smartlink Use?

The SortExpress smartlink scores landing pages based on any combination of:

The scoring considers all these parameters in combination, not in isolation. A keyword that converts well on desktop may perform poorly on mobile — the AI learns these interactions automatically.

Smartlink vs Manual Rules vs A/B Testing

Manual rules (e.g., "show page B to mobile users") are static and only capture one dimension at a time. You'd need thousands of rules to cover every combination of parameters.

A/B testing finds a single winner for the average visitor, then stops optimizing. See our full comparison of A/B testing vs AI routing.

A smartlink routes dynamically for every visitor profile simultaneously, improves continuously, and requires zero ongoing maintenance once set up.
