Wix has made significant SEO improvements over the years, and a DIY approach here mostly involves using the platform's built-in SEO tools thoroughly rather than working around limitations.
Use the Built-In SEO Settings Panel Thoroughly
Wix provides direct fields for titles, descriptions, and other on-page elements that are worth filling out completely on every page.
Check Site Speed Specifically
Page speed has historically been a consideration on some website builder platforms, so it's worth verifying rather than assuming it's optimal by default.
Confirm Your Sitemap Is Being Generated Correctly
Wix generates a sitemap automatically, but it's still worth confirming it accurately reflects your live pages.
Next step: Use the SEO Audit to check your Wix site's current technical health.
