Wix's Lighthouse SEO score of 100: what it means and how to maintain it

Module 2: How to Set Up Your Wix Site for Maximum SEO | Lesson 23 of 687 | 22 min read

Wix achieved a perfect Lighthouse SEO score of 100 for its platform infrastructure — but this does not mean every Wix page automatically scores 100. The platform provides the foundation; what you build on it determines your individual page scores. This lesson explains what the Lighthouse SEO audit measures and how to keep your Wix pages at the top.

What Lighthouse's SEO Audit Checks

Document has a meta viewport tag (mobile-friendliness)
Document has a title element (not missing or empty)
Document has a meta description
Page has a valid hreflang attribute
Document uses legible font sizes on mobile
Tap targets are sized appropriately for mobile interaction
Links are crawlable (not inside JavaScript that blocks Googlebot)
robots.txt is valid and not blocking critical resources
Document does not use plugins (Flash, Java applets)
Page has a valid rel=canonical link

Why Platform Score Differs from Individual Page Score

The Wix platform infrastructure passes all Lighthouse SEO technical checks by default. But your specific page configuration can override the platform defaults in ways that reduce the score. Adding a noindex directive when you did not intend to, forgetting a meta description on a key page, or using text that is too small on mobile — these page-level choices break the perfect platform foundation.

Common Causes of Sub-100 Lighthouse SEO Scores on Wix

Missing meta description on the page (empty description field in Wix SEO panel)
Accidentally setting noindex on a page meant to be indexed
Using very small text (under 12px) that fails the font size check
Buttons or links too close together for mobile tap targets
hreflang errors when using multiple languages without correct setup
Empty title tags on dynamic pages with missing data values

Audit Method: Run Lighthouse SEO audits page by page in Chrome DevTools (Lighthouse tab > select SEO). Focus on your highest-traffic pages first. The score is pass/fail per check — a single failed check drops from 100 to 89 or lower, making it easy to identify exactly what to fix.

Maintaining High Scores as Your Site Grows

As you add new pages, apps and content to your Wix site, new Lighthouse SEO issues can appear. Build a quarterly Lighthouse audit of your 20 most important pages into your SEO maintenance schedule. Most Wix Lighthouse SEO failures are quick fixes — a missing meta description takes 30 seconds to add once identified.
