How to Run a Quarterly Technical SEO Audit Like a Pro

ByErwee Coetzee

Every strong SEO strategy rests on one thing: a technically sound website. Yet, too many businesses overlook technical SEO until rankings start to fall or pages stop appearing in Google altogether.

Running a quarterly technical SEO audit keeps your site healthy, fast, and search-ready — preventing minor technical issues from turning into major visibility problems. It’s how professionals maintain performance consistency and algorithm resilience.

Let’s walk through exactly how to run one like a pro.

1. Why Regular Technical Audits Are Non-Negotiable

Think of your website as an engine — powerful when maintained, but prone to slowdowns if ignored.

Over time, plugins, updates, and design tweaks can introduce technical issues that silently erode performance. A quarterly SEO audit acts as preventive maintenance, keeping your site crawlable, secure, and user-friendly.

Even the most compelling content and strong backlinks won’t perform if search engines can’t access or interpret your pages correctly.

2. What a Technical SEO Audit Really Is

A technical SEO audit is a comprehensive check-up that ensures search engines can crawl, index, and understand your website efficiently.

It focuses on the infrastructure behind your content — things like:

  • Crawlability and indexation
  • Page speed and Core Web Vitals
  • Mobile usability
  • Site architecture and internal linking
  • HTTPS security
  • Schema markup and structured data

In short, it verifies that your website meets Google’s technical expectations, helping your content reach its full ranking potential.

3. Why You Should Audit Quarterly

Google updates its algorithms constantly, and every CMS update or content upload carries potential risks.

Quarterly audits help you:

  • Catch new technical issues early.
  • Monitor trends in performance.
  • Maintain consistency across updates.
  • Adapt to evolving SEO standards (like Core Web Vitals or AI-driven indexing).

For SMEs, quarterly audits strike the right balance — frequent enough to stay proactive, yet manageable in cost and time.

4. Step 1: Check Crawlability and Indexation

If Google can’t crawl or index your content, it can’t rank it. Start your audit by ensuring your website is accessible and fully visible to search engines.

How to do it:

  • Review the Index Coverage Report in Google Search Console.
  • Identify “noindex” tags or disallowed URLs in robots.txt.
  • Confirm your XML sitemap is accurate and submitted.
  • Look for redirect loops and broken links (using Screaming Frog or Sitebulb).

Goal: Every valuable page should be discoverable — and every irrelevant or duplicate page should be excluded.

5. Step 2: Test Page Speed and Core Web Vitals

Speed is both a ranking signal and a user trust factor.

Tools:

  • Google PageSpeed Insights
  • GTmetrix
  • Lighthouse

Check:

  • Largest Contentful Paint (LCP) — under 2.5 seconds.
  • Cumulative Layout Shift (CLS) — under 0.1.
  • Total Blocking Time (TBT) — under 300ms.

Optimise images, enable caching, and minimise render-blocking resources. Even small technical fixes can yield measurable results in conversions and engagement.

6. Step 3: Assess Mobile Usability

With mobile-first indexing, your mobile version is now the primary version Google evaluates.

Audit tasks:

  • Run the Mobile Usability Report in Search Console.
  • Check responsiveness on multiple screen sizes.
  • Ensure fonts, buttons, and menus are touch-friendly.
  • Avoid intrusive pop-ups and overlapping elements.

A smooth, mobile-first experience reduces bounce rates and boosts overall ranking performance.

7. Step 4: Verify Security and HTTPS Integrity

Users — and Google — expect security. Without HTTPS, browsers may flag your site as unsafe, instantly damaging trust.

Check for:

  • A valid SSL certificate (no mixed-content warnings).
  • Redirects from HTTP to HTTPS.
  • Security headers such as HSTS and CSP (Content Security Policy).

An expired or misconfigured certificate can harm both rankings and reputation.

8. Step 5: Review Structured Data and Schema Markup

Structured data helps search engines interpret your pages accurately and display rich results (stars, FAQs, reviews).

How to audit schema:

  • Test your pages with Google’s Rich Results Test.
  • Validate JSON-LD markup through Schema.org.
  • Ensure schema types (e.g., Organisation, Product, FAQ, Article) are correctly applied.
  • Check for missing or deprecated attributes.

Well-implemented schema boosts visibility, CTR, and authority perception.

9. Step 6: Analyse Internal Linking and Site Architecture

Internal linking guides both users and search engines through your site. It defines hierarchy and distributes link equity.

Audit actions:

  • Ensure every key page has at least one internal link.
  • Identify orphaned pages (no inbound links).
  • Fix broken internal links.
  • Use descriptive, keyword-relevant anchor text.

A clear, intuitive structure improves crawl efficiency and strengthens topical authority.

10. Step 7: Evaluate Duplicate Content and Canonicals

Duplicate content confuses crawlers and splits ranking signals.

Tasks:

  • Scan for duplicate titles, meta descriptions, or thin pages using Screaming Frog or Ahrefs Site Audit.
  • Implement canonical tags to designate preferred versions.
  • Merge or redirect redundant content.

This ensures your strongest pages retain full authority and focus.

11. Step 8: Confirm Analytics and Tag Tracking

Your audit means little without accurate tracking.

Verify:

  • Google Analytics 4 (GA4) and Search Console connections.
  • Correct placement of tracking codes (no duplicates).
  • Event and conversion tracking accuracy.
  • Consistent goal setup across views.

Clean data equals reliable insights — essential for ROI reporting.

12. Step 9: Document Findings and Prioritise Fixes

The goal of an audit isn’t just diagnosis — it’s action.

Create a summary report with issues categorised by impact and urgency:

  • High impact / low effort: Quick fixes (broken links, redirect errors).
  • High impact / high effort: Core web vital improvements.
  • Low impact / low effort: Metadata consistency checks.

Assign tasks to your development or content teams and review progress within your next quarter’s audit cycle.

13. Step 10: Automate for Continuous Improvement

Manual audits are vital, but automation keeps your site protected between reviews.

Set up:

  • Weekly crawls with Ahrefs, Sitebulb, or SEMrush.
  • Alerts for downtime or indexing errors.
  • Automated sitemap and backup updates.

Automation turns audits from a once-a-quarter scramble into an ongoing safeguard.

14. Stay Proactive, Not Reactive

The best SEO professionals know that prevention is better than recovery.

A quarterly technical SEO audit helps you:

  • Catch issues before rankings drop.
  • Maintain faster load speeds and stronger UX.
  • Adapt to Google’s evolving technical standards.
  • Build long-term stability for your digital presence.
