How to Perform a Technical SEO Audit: A Simple, Complete Checklist

Technical SEO Audit

Why a technical audit matters

A technical audit finds issues that hide your pages from search or slow visitors down. Fixing these items makes the site easier to crawl, easier to use, and easier to rank.

Step 1: Crawl the site

Run a full crawl to list all pages and issues.

What to look for:

  • 404 errors, 500 errors, redirect chains
  • Pages with no title/H1, duplicate titles
  • Mixed content warnings (HTTP assets on HTTPS pages)

Fix first: Broken links and redirect chains—they hurt both users and SEO.

Step 2: Indexation and coverage

Open Google Search Console → Coverage/Pages.

  • Remove noindex from important pages
  • Noindex thin or duplicate pages you don’t want in search
  • Ensure your XML sitemap lists only valuable, live URLs
  • Check canonical tags—each key page should self-reference

Outcome: Google sees a clean set of pages you actually care about.

Step 3: Site structure and internal linking

Keep important pages near the homepage. Use helpful anchor text.

  • Link services → related case studies and blogs
  • Link blogs → your service pages
  • Avoid orphan pages (no internal links pointing to them)

Why it matters: Smart internal links pass relevance and help users find answers quickly.

Step 4: On-page basics

  • Clear, unique titles and meta descriptions
  • One H1 per page; logical H2/H3s
  • Intro paragraph that explains the page in one or two lines
  • Descriptive image alt text
  • Schema markup where it adds value (FAQ, Services, Organization)

Step 5: Speed and Core Web Vitals

Improve LCP, CLS, and INP:

  • Compress and resize images; serve WebP
  • Lazy-load below-the-fold media
  • Delay non-critical scripts; remove unused plugins
  • Use a lightweight theme; enable caching and a CDN if needed

Outcome: Pages feel snappy on mobile and desktop. Users stay longer and convert better.

Step 6: Security & consistency

  • Full HTTPS across the site
  • Fix mixed content
  • One www/non-www version and one HTTP/HTTPS version (no duplicates)

Step 7: Analytics and tracking

  • Set up GA4 with basic events (form submissions, button clicks)
  • Connect Google Search Console
  • Create a simple dashboard that focuses on results: impressions, clicks, top pages, conversions

Step 8: Prioritized action plan (30–60 days)

Write a short plan with due dates and owners.

  • Week 1–2: fix broken links, redirects, sitemap, indexation
  • Week 3–4: speed and Core Web Vitals
  • Week 5–8: on-page upgrades and internal linking; add helpful FAQs

Tip: Review Search Console every week during this period to confirm improvements.

Common pitfalls

  • Too many plugins: slows the site and causes conflicts
  • Auto-generated titles: create duplicates and lower CTR
  • Thin location pages: add real details—services offered, hours, photos, parking notes
  • Skipping redirects: you’ll lose page value and history

FAQs

How often should I run a technical audit?
Run a light check monthly and a deeper audit every quarter, or after any big changes.

Will a technical audit alone boost rankings?
It clears the path. Real growth comes from technical health plus useful content and relevant links.
