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

Technical SEO Audit: The Repeatable Framework

This guide focuses on high-impact technical fixes. If the site doesn't crawl or index correctly, content quality is irrelevant. Follow this workflow to identify and prioritize issues.

Phase 1: Crawl and Index Coverage

The Crawl

Use Screaming Frog or Sitebulb. 1. Set the limit to 5,000 URLs for a sample. 2. Check for 4xx and 5xx status codes. 3. Look for redirect chains (301 -> 301 -> 200).

Command/Check: Filter by Status Code -> 4xx Filter by Status Code -> 5xx Reports -> Redirect Chains

Index Coverage

Use Google Search Console (GSC). 1. Go to Indexing -> Pages. 2. Focus on "Excluded" pages. Specifically: "Crawled - currently not indexed" and "Discovered - currently not indexed." 3. If these are high-value pages, your internal linking or content quality is the bottleneck.

Common Mistake: Blocking CSS/JS files in robots.txt. Google needs to render the page to understand it.

Phase 2: Core Web Vitals (CWV)

CWV is a ranking factor. Focus on the Field Data in GSC.

  1. LCP (Largest Contentful Paint): Usually caused by unoptimized hero images or slow server response (TTFB).
  2. CLS (Cumulative Layout Shift): Caused by images without explicit width/height attributes or dynamic content injecting above existing content.
  3. INP (Interaction to Next Paint): Caused by heavy JavaScript execution blocking the main thread.

Action: Run a PageSpeed Insights report. If LCP is the issue, implement fetchpriority="high" on the hero image and preload it.

Phase 3: Canonical and Duplicate Content

Duplicate content dilutes authority.

  1. Canonical Tags: Ensure every page has a self-referencing canonical tag.
  2. Parameters: Check if ?utm_source or ?sort=price URLs are being indexed.
  3. WWW vs Non-WWW / HTTP vs HTTPS: Ensure only one version is accessible.

Check: Use the "Canonical" column in Screaming Frog. If a page canonicalizes to a different URL, verify that the target URL is actually the intended primary version.

Phase 4: Schema Markup

Schema is not a direct ranking factor, but it wins SERP real estate (rich snippets).

  1. Required Schema: WebPage, Organization, and BreadcrumbList.
  2. Validation: Use the Schema Markup Validator.
  3. Common Mistake: Implementing multiple conflicting schema types on one page (e.g., Article and Product on a blog post).

Phase 5: Internal Linking and Site Architecture

A flat architecture is best. No page should be more than 3 clicks from the homepage.

  1. Orphan Pages: Pages with zero internal links. These will not rank.
  2. Link Equity: Identify high-authority pages (via GSC or Ahrefs) and link from them to your "money" pages.
  3. Broken Links: Use Screaming Frog to find internal 404s.

Phase 6: Sitemap and Robots.txt

  1. Sitemap: Must be XML, under 50MB, and include only 200-status indexable pages. Submit it to GSC.
  2. Robots.txt: Test in the GSC robots.txt tester. Ensure you aren't blocking Googlebot from critical JS/CSS files.

Prioritized Fix List: Impact vs. Effort

Issue Impact Effort Priority
4xx/5xx Errors High Low 1
Redirect Chains Medium Low 2
Core Web Vitals (LCP) High High 3
Missing Canonical Tags High Low 1
Orphan Pages Medium Medium 4
Schema Implementation Medium Medium 5

Checklist for Execution

  • [ ] Crawl: Ensure no 4xx errors exist on internal links.
  • [ ] GSC: Check "Pages" report for "Crawled - currently not indexed."
  • [ ] HTTPS: Verify the entire site is on HTTPS with no mixed content.
  • [ ] Canonical: Ensure all pages have a self-referencing canonical.
  • [ ] Robots.txt: Verify no critical CSS/JS is blocked.
  • [ ] Sitemap: Ensure it only contains 200-status URLs.
  • [ ] Schema: Validate BreadcrumbList and Organization schema.
  • [ ] CWV: Optimize images (WebP format, explicit dimensions).

Common Mistakes to Avoid

  1. The "Noindex" Trap: Accidentally leaving noindex tags on site-wide templates during development and pushing to production.
  2. Ignoring Log Files: If you have a massive site (100k+ pages), rely on server logs, not just crawls, to see how Googlebot actually spends its crawl budget.
  3. Over-optimizing Internal Links: Using exact-match anchor text for every single internal link. Vary your anchor text naturally.
  4. Ignoring Mobile: Always audit the mobile version of the site. Google uses Mobile-First Indexing. If it’s not on mobile, it doesn’t exist to Google.
