What is CRO?

What is CRO?

What is CRO?

At its core, Conversion Rate Optimization (CRO) is about increasing the percentage of website visitors who take a desired action - in this case, booking a room. 

The formula:
Conversion Rate = (Total Website Bookings / Total Website Visitors) x 100

The Method: Volume negates luck

Remember school experiments? You changed one thing, measured the result, and wrote down what happened. CRO is the same - only the lab is your website, and the result is revenue.


Our CRO loop:

  1. Review: Where are guests dropping off in the booking journey?

  2. Analyze: What can you improve? Think unclear copy, weak imagery, hidden fees, slow pages.

  3. Test: Change one thing at a time (A/B testing is your new best friend 🤩)

  4. Check results: Did the new version perform better?

  5. Implement or learn: If it did, implement it. If it didn’t, document why and try the next best idea.

The key here is volume. You may miss on test 1, 2, or 3 - but consistent testing is what will give you results.

Set Up

Set Up

Set Up

A boutique hotel we work with saw a pattern: traffic was healthy, but most users dropped off on the room page.

What we did:

  • Hypothesis: “Improving image quality will reduce hesitation.”

  • Design: A version with high-quality, fast-loading images.

  • A/B test: Split traffic evenly, show both versions to users.

  • Result: More completed bookings on the new version.

  • Action: Keep the winner, move on to the next friction point.

No huge redesign. Just one small, focused change, that made more guests book.

What to Test First

You can't test everything at once.

Your first audit should surface at least 20 test ideas (check out our 50 CRO Test Ideas document for inspiration).

Prioritize ones that:

  • Could drive a big impact - for guests and revenue.

  • Are easy to implement

  • Fit your hotel’s goals

FAQ

FAQ

Do I need all these tools?

Start with the basics: analytics and A/B testing. Add others as you grow.

Are free tools good enough?

For many hotels, yes. Google Analytics is free, and that’s the gold standard. Hotjar’s free plan is more than enough if you’re just starting.

Paid tools offer more features but aren't always necessary. 

How do I choose between similar tools?

Look for ease of use, customer support, and integration with your PMS/booking engine and CRM.

How long should a test run?

It depends on traffic. Aim for at least two weeks, or until you reach statistical significance.

What if the test doesn't show clear winners?

That’s still a win - you discarded a hypothesis. Log it and test the next idea.

Can small hotels do CRO too?

Yes - however, if you have fewer than ~1,000 monthly unique visitors, focus first on growing traffic to your direct channel. Then optimize.
