What happens when the developer decides to change the site's navigation without testing?

I have seen this happen on a project where the development team decided to simplify the navigation, thinking it would make the user experience more fluid. The result? A significant drop in conversions, as most users simply couldn't find the products they wanted. The lesson here is clear: any changes in navigation should be tested with real users to see how it performs in practice.

When optimizing navigation improves usability but harms SEO

On another occasion, a team implemented improvements to the navigation that indeed had a good impact on Lighthouse, but without realizing it, they ended up removing old content that still generated incoming links. Organic traffic plummeted, and no one noticed until it was too late. The thing is, well-intentioned navigation can damage your SEO if there isn't attention to the content and indexing that supports the most relevant pages.

The classic mistake of removing categories that improve navigation but destroy SEO hierarchy

Another frequent mistake I witnessed was when a client thought that removing some categories would help clarify navigation. What happened was that, without the categories, the site lost not only organization but also the relevance those pages had for SEO. By removing them, the site lost space in Google ads and saw a sudden drop in visibility.

Practical checklist to avoid mistakes in navigation changes

• Conduct A/B testing before implementing changes.
• Keep categories on the site to maintain hierarchy.
• Monitor organic traffic metrics after any change.
• Conduct constant feedback with users during navigation.
• Document changes to facilitate future analysis.

Common mistakes in navigation changes

• Modify URLs without proper redirects.
• Remove the search bar when reorganizing menus.
• Not considering the impact on mobile and desktop simultaneously.
• Forget to optimize anchor texts and internal links.
• Assume all users know how to use a dropdown menu.

How to apply navigation improvements in practice

1. Analyze the current navigation performance using analytics tools.
2. Make a list of changes, preferably based on real usage data.
3. Conduct A/B tests with different versions.
4. Collect qualified feedback from users.
5. Implement the version that shows the best conversion results.
