Hick's law in plain English
The law comes from research by psychologists William Edmund Hick and Ray Hyman in the early 1950s. They found that decision time rises as the number of choices increases, though not in a straight line: it grows more slowly as options are added. The practical lesson for websites is simple. Fewer, clearer choices help people act faster.
Why it matters for conversion
A visitor who has to compare eight menu items, twelve services and four buttons before they can enquire is spending effort on navigation instead of on deciding to contact you. That extra cognitive load leads to hesitation, and hesitation leads to people leaving. Applying Hick's law usually means:
- shorter, clearer navigation
- one primary call to action per page
- services grouped into a few clear categories
- forms that ask only what is needed
How to apply Hick's law to your website
- Trim the main menu. Five to seven top-level items is a sensible ceiling for most service businesses. Move secondary pages into a dropdown or the footer.
- Group, do not just cut. If you offer many services, sort them into a few categories so visitors choose a category first. This is part of good information architecture.
- Highlight a recommended option. On pricing or package pages, marking one option as "most popular" shortens the decision.
- Use one main action per page. Keep secondary actions visually quieter.
- Break long forms into steps so each screen asks for one small decision.
When more choice is fine
Hick's law is about decision time, not a rule that fewer options always win. A visitor who knows exactly what they want can scan a long list quickly, for example a list of locations or an A–Z glossary. The goal is to remove unnecessary choices from the moments where people decide whether to enquire.
A quick example
A clinic's homepage showed 14 treatments as equal tiles, plus "Book", "Call", "Email" and "WhatsApp" buttons. Grouping treatments into four areas and making "Book an appointment" the clear main button, with "Call us" as a quieter option, gives visitors a shorter path to a decision.
