Technical SEO Audit Checklist — Find and Fix Hidden Issues

A technical SEO audit reveals hidden issues that prevent your site from ranking well. Here's our comprehensive checklist.

Crawlability and Indexing

• Check robots.txt for accidental blocking
• Review XML sitemap structure and submission
• Ensure important pages are crawlable and indexable
• Fix broken internal links (404 errors)
• Check for duplicate content issues

Site Architecture

• Use clear, logical URL structures
• Implement breadcrumb navigation
• Create a flat site hierarchy (important pages within 3 clicks)
• Use internal linking to distribute page authority

Page Speed and Core Web Vitals

• Test LCP, FID, and CLS scores
• Optimise images and videos
• Minimise render-blocking resources
• Enable compression and browser caching
• Review server response times

Mobile Optimisation

• Verify mobile responsiveness
• Check touch target sizes
• Ensure text is readable without zooming
• Test mobile page speed separately

Structured Data

• Implement Schema.org markup for your business type
• Use FAQ schema for question pages
• Add review schema for testimonial pages
• Test structured data with Google's Rich Results Test

Run this audit quarterly to maintain strong technical SEO foundations.

We check: crawlability (robots.txt, sitemaps), indexability (canonical tags, meta robots), page speed (Core Web Vitals), mobile usability, schema markup, HTTPS, duplicate content, broken links, redirect chains. We run this checklist before launch and every quarter after. Get the technical foundation right first.

SEO is not a one-and-done thing. Google updates its algorithm constantly. Competitors keep working on their sites. Rankings shift. The businesses that stay on top keep investing in SEO month after month. The good news: SEO compounds. Six months of solid work can pay off for years.

Local SEO works especially well in South Africa. When someone searches “plumber near me” or “web designer Johannesburg,” Google shows businesses with optimised profiles, local citations, and relevant content. We help clients capture this traffic by building a complete local SEO foundation.

SEO takes time but the payoff is real. Unlike ads that stop working when you stop spending, organic traffic keeps coming. A page ranked on page one today can keep bringing leads for years. Combine good SEO with quality content and you have one of the highest ROI marketing channels available.
