Quarterly technical SEO audits: the complete Wix checklist

While weekly GSC checks catch acute issues and monthly audits address content decay, a quarterly technical SEO audit is your comprehensive health check that examines every technical aspect of your Wix site. This is where you catch the slow-building problems that do not trigger immediate alerts but gradually erode your search performance. This lesson provides the definitive quarterly audit checklist with 50 points, all specifically tailored for Wix websites.

Part 1: Crawlability and Indexation Health (Points 1-12)

Crawlability and indexation checklist

• Run a full site crawl using Screaming Frog (free up to 500 URLs) and note the total pages discovered vs pages in your Wix sitemap
• Check robots.txt at yourdomain.com/robots.txt for any unintended blocking directives
• Verify your XML sitemap at yourdomain.com/sitemap.xml loads correctly and contains all important pages
• Compare GSC indexed page count to your sitemap page count, a large gap indicates indexing issues
• Check for orphan pages (pages with no internal links pointing to them) in your crawl report
• Identify and fix redirect chains (more than one redirect in sequence) using the Wix URL Redirect Manager
• Check for redirect loops where pages redirect back and forth endlessly
• Verify canonical tags on all important pages are pointing to the correct URLs
• Check for pages accidentally set to noindex in the Wix SEO panel
• Verify that pagination is handled correctly on Wix blog archives and product listings
• Ensure all pages are reachable within 3 clicks from the homepage via internal links
• Check crawl stats in GSC for any unusual patterns in crawl frequency or response codes

Part 2: Core Web Vitals and Page Speed (Points 13-22)

Performance benchmarking checklist

• Run your homepage through PageSpeed Insights and record LCP, CLS and INP scores for both mobile and desktop
• Test your 5 highest-traffic pages individually in PageSpeed Insights and record all scores
• Compare current CWV scores to last quarter benchmarks to identify regressions or improvements
• Check GSC Core Web Vitals report for the total number of URLs in Good, Needs Improvement and Poor categories
• Audit all hero images on your top pages, ensure each is under 200KB and in WebP format
• Review all third-party Wix apps installed on your site and remove any that you no longer use
• Check for excessive custom code or scripts added via Wix Settings > Custom Code that may be slowing pages
• Test mobile page load time on a real mobile device, not just in desktop developer tools
• Review font loading and ensure custom fonts are not causing visible text reflow (CLS issues)
• Benchmark your site speed against your top 3 competitors using PageSpeed Insights

Part 3: Mobile Usability (Points 23-28)

Mobile usability checklist

• Check GSC Mobile Usability report for any new errors
• Test your Wix site on at least 2 different mobile screen sizes using the Mobile-Friendly Test tool
• Verify that all tap targets (buttons, links) are at least 48x48 pixels and have adequate spacing
• Check that no content is wider than the screen, causing horizontal scrolling on mobile
• Verify that text is readable without zooming on all pages, minimum 16px font size for body text
• Test all forms, contact pages and interactive elements on a real mobile device

Part 4: Structured Data and Rich Results (Points 29-36)

Structured data audit checklist

• Run your homepage through Google Rich Results Test and fix any errors or warnings
• Test 5 representative pages (blog post, service page, product page, about page, FAQ page) in Rich Results Test
• Check GSC Enhancements report for any structured data errors that appeared this quarter
• Verify that Wix auto-generated schema (for blog posts, products, events) is correct and complete
• Check any custom JSON-LD you added via Wix Custom Code is still valid and has not been broken by site updates
• Verify your LocalBusiness schema (if applicable) has correct NAP information and opening hours
• Check that FAQ schema is implemented on pages with frequently asked questions sections
• Review breadcrumb schema to ensure navigation structure is correctly represented

Part 5: Internal Linking Structure (Points 37-42)

Internal linking audit checklist

• Review the internal link distribution in your crawl report, important pages should have the most internal links
• Check for broken internal links using Screaming Frog or a free broken link checker tool
• Verify that your site navigation menu includes links to all key category and service pages
• Check that blog posts link to relevant service pages and vice versa to distribute authority
• Review anchor text usage in internal links, use descriptive keyword-rich anchors rather than generic click here
• Ensure your Wix footer contains links to important pages that might not appear in the main navigation

Part 6: Security, HTTPS and Technical Health (Points 43-50)

Security and technical health checklist

• Verify HTTPS is working correctly on all pages, no mixed content warnings
• Check that the Wix SSL certificate is active and valid in Settings > Domains
• Confirm no HTTP pages are accessible, all should redirect to HTTPS automatically
• Check GSC Security Issues report for any malware or hacking alerts
• Review your Wix site permissions and ensure only authorised team members have editor access
• Verify that your custom domain DNS records are still correctly pointing to Wix servers
• Check that hreflang tags are correctly implemented if you have multilingual Wix site versions
• Review and update your 404 page to include helpful navigation links back to key pages

Complete How-To Guide: Running the Quarterly Technical Audit

Follow this process every quarter

• Schedule a full day or half-day block in your calendar for the audit at the start of each quarter (January, April, July, October)
• Run a full Screaming Frog crawl of your Wix site and export the results for analysis
• Work through each section of the 50-point checklist above, marking each item as Pass, Fail or Needs Attention
• For every item marked Fail or Needs Attention, create a specific action item with a deadline
• Prioritise action items by impact: critical issues (security, major indexing problems) first, then high-impact (CWV, broken links), then moderate (schema, internal linking)
• Fix critical and high-impact issues within the first week after the audit
• Schedule moderate issues for completion within the current month
• Document all findings and fixes in your SEO maintenance spreadsheet for year-over-year comparison
• Compare this quarter results to last quarter to track improvement trends
• After fixes are implemented, re-run PageSpeed Insights and Rich Results Test on key pages to verify improvements
