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

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

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.

How to Run a Lighthouse SEO Audit on Your Wix Pages

How to audit Wix pages with Lighthouse and fix common SEO score failures

• Open your Wix site in Google Chrome and navigate to the most important page you want to audit (homepage, main service page, or top-traffic page).
• Press F12 to open Chrome DevTools, then click the Lighthouse tab in the DevTools panel.
• Under Categories, untick all options except SEO. Under Device, select Mobile for the most critical test.
• Click Analyse page load and wait for Lighthouse to complete the audit (30-60 seconds).
• Review the SEO score and scroll down to the Opportunities and Diagnostics sections to see which specific checks failed.
• For a missing meta description failure: open your Wix Editor, click the page in the Pages panel, select SEO, and enter a 150-160 character description in the Meta Description field on the SEO Basics tab.
• For a font size failure (text too small): open the Wix Editor, select the text element with small text, increase the font size to at least 12px on mobile view using the mobile editor.
• For a tap targets too small failure: open the Wix Editor in mobile view and increase the size or spacing of any buttons or links flagged by Lighthouse.
• After fixing each issue, republish the page and rerun the Lighthouse SEO audit to confirm the score has improved.
• Repeat this audit for your top 20 pages quarterly, keeping a log of scores and fixes so you can demonstrate improvement over time.

How to Fix a Wix Page Accidentally Marked as Noindex

How to find and remove accidental noindex tags from Wix pages

• Open Google Search Console and navigate to Coverage > Excluded. Look for a large number of pages listed under "Excluded by noindex tag" — this may indicate pages were accidentally noindexed.
• Click on the "Excluded by noindex tag" category to see a list of affected page URLs.
• For each affected URL, open the Wix Editor, click the relevant page in the Pages panel, and select SEO.
• Navigate to the Advanced SEO tab and look for the Robots Meta Tag section.
• Check whether the noindex toggle is switched on. If it is and this page should be indexed, switch it off.
• Publish the page after making the change.
• Return to GSC URL Inspection, enter the page URL, and click Request Indexing to prompt Google to recrawl the page with the updated robots directive.
• Wait 3-5 days and then recheck GSC Coverage to confirm the page has moved from Excluded to Valid.
• To prevent accidental noindex in the future, add a monthly check of your GSC Coverage Excluded report to your SEO maintenance schedule.
• If you find a large number of pages with accidental noindex, prioritise fixing your highest-traffic and most commercially important pages first.
