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.
- LCP (Largest Contentful Paint): Usually caused by unoptimized hero images or slow server response (TTFB).
- CLS (Cumulative Layout Shift): Caused by images without explicit width/height attributes or dynamic content injecting above existing content.
- 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.
- Canonical Tags: Ensure every page has a self-referencing canonical tag.
- Parameters: Check if
?utm_sourceor?sort=priceURLs are being indexed. - 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).
- Required Schema:
WebPage,Organization, andBreadcrumbList. - Validation: Use the Schema Markup Validator.
- Common Mistake: Implementing multiple conflicting schema types on one page (e.g.,
ArticleandProducton 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.
- Orphan Pages: Pages with zero internal links. These will not rank.
- Link Equity: Identify high-authority pages (via GSC or Ahrefs) and link from them to your "money" pages.
- Broken Links: Use Screaming Frog to find internal 404s.
Phase 6: Sitemap and Robots.txt
- Sitemap: Must be XML, under 50MB, and include only 200-status indexable pages. Submit it to GSC.
- 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
BreadcrumbListandOrganizationschema. - [ ] CWV: Optimize images (WebP format, explicit dimensions).
Common Mistakes to Avoid
- The "Noindex" Trap: Accidentally leaving
noindextags on site-wide templates during development and pushing to production. - 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.
- Over-optimizing Internal Links: Using exact-match anchor text for every single internal link. Vary your anchor text naturally.
- 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.
