How to Run a Technical SEO Audit With a Prioritized Fix Plan

Technical SEO Audit: The Repeatable Framework

Technical SEO is not about guessing; it is about removing friction between the search engine crawler and your content. This framework is designed to be executed in a repeatable cycle to ensure your site remains healthy.

1. Crawl and Index Coverage

The goal is to ensure Google sees exactly what you intend for it to see, and nothing more.

• Action: Run a crawl using Screaming Frog. Set the limit to 5,000 URLs for a baseline.
• Checklist:
  • Are there 4xx or 5xx status codes?
  • Are redirected chains (301 -> 301 -> 200) present?
  • Check Google Search Console (GSC) "Indexing" report. Look for "Crawled - currently not indexed" and "Discovered - currently not indexed."
• Common Mistake: Ignoring "Crawled - currently not indexed." This usually means the content is low quality or lacks internal link equity. Fix by improving content or adding internal links.

2. Core Web Vitals (CWV)

Google uses CWV as a ranking factor. Focus on LCP (Loading), INP (Interactivity), and CLS (Visual Stability).

• Action: Use PageSpeed Insights (PSI) for lab data and GSC "Core Web Vitals" for field data.
• Commands/Tools: Use the Chrome DevTools "Lighthouse" tab for local debugging.
• Checklist:
  • Is LCP > 2.5s? Optimize images (WebP/AVIF) and implement lazy loading.
  • Is CLS > 0.1? Set explicit width/height attributes on images and iframes.
  • Is INP > 200ms? Identify heavy JavaScript execution tasks in the "Performance" tab of DevTools.
• Common Mistake: Trying to fix CWV by installing "all-in-one" optimization plugins that cause more conflicts than they solve. Optimize server-side first (Gzip/Brotli, caching).

3. Canonical and Duplicate Content

Duplicate content dilutes your ranking signals.

• Action: Audit canonical tags in Screaming Frog.
• Checklist:
  • Does every page have a self-referencing canonical tag?
  • Are parameters (e.g., ?utm_source=) causing duplicate pages? Use rel="canonical" to point to the clean URL.
  • Check for mixed HTTP/HTTPS canonicals.
• Common Mistake: Using noindex and canonical on the same page. Pick one. If a page is low value, noindex it. If it’s a duplicate of a main page, canonical it.

4. Schema Markup

Schema helps Google understand your entity and content type.

• Action: Test your URLs with the Schema Markup Validator.
• Checklist:
  • Implement Article or BlogPosting schema for posts.
  • Implement Product schema (with price and availability) for e-commerce.
  • Implement BreadcrumbList for site navigation.
• Common Mistake: Adding schema that doesn't match the visible content. Google will ignore it or penalize the site for deceptive markup.

5. Internal Linking

Internal links distribute "PageRank" throughout your site.

• Action: In Screaming Frog, look at the "Inlinks" tab.
• Checklist:
  • Are your money pages receiving the most internal links?
  • Are you using descriptive anchor text? Avoid "click here."
  • Are there orphaned pages (0 internal links)?
• Common Mistake: Relying solely on the main menu for internal linking. Your content should link to other relevant content within the body text.

6. Sitemap and Robots.txt

These are your instructions to the crawler.

• Action: Verify robots.txt at domain.com/robots.txt and check the sitemap in GSC.
• Checklist:
  • Does robots.txt block important CSS/JS files?
  • Is the XML sitemap dynamic? It should update automatically when you publish content.
  • Does the sitemap contain only 200-status, indexable URLs?
• Common Mistake: Including noindex pages or 301 redirects in the XML sitemap. Keep it clean.

Prioritized Fix List: Impact vs. Effort

Task	Impact	Effort	Priority

Hands-on Execution Checklist

1. Crawl: Run Screaming Frog; export all 4xx/5xx errors.
2. GSC Check: Export "Indexing" errors; cross-reference with crawl data.
3. CWV Audit: Run PSI on your top 10 landing pages.
4. Schema Check: Validate top 5 pages using the Schema Validator.
5. Fix Phase: Execute fixes in order of priority (see table).
6. Re-crawl: Confirm all 4xx/5xx errors are gone.
7. Submit: Request re-indexing in GSC for major structural changes.

Final Thoughts

Technical SEO is a process of elimination. If you fix the crawl errors and ensure the site structure is logical, you give Google the best chance to rank your content. Don't get distracted by "vanity" metrics; focus on what prevents the crawler from accessing your site.
