This SEO audit checklist for Australian websites is designed to produce decisions, not a giant export of warnings. Start with whether Google can access the right pages, then evaluate whether those pages satisfy Australian customers and generate measurable enquiries.
Check discovery, indexing and canonical signals
Review robots.txt, XML sitemaps, Search Console indexing reports and live URL tests. Confirm that core services return a successful status, use self-referencing canonicals where appropriate and are internally linked. Redirects and 404s are not automatically bad; judge whether the affected URL should exist.
Inspect signs of compromise such as spam URLs, unknown administrators, malicious files or unexpected foreign-language pages. Security incidents can create thousands of crawl problems, so cleanup and access control come before cosmetic optimisation.
Review templates, speed and mobile usability
Test representative service, article, location and conversion pages. Check Core Web Vitals, heading structure, image dimensions, navigation, form labels and tap targets. Google recommends good Core Web Vitals but also stresses that page experience is broader than one score.
Look for duplicate titles, thin archives, parameter URLs and templates that hide essential content behind scripts.
Evaluate relevance, trust and conversion
Map each valuable query cluster to one primary page. Check whether the page demonstrates experience, explains the service, answers pricing or process objections and offers a clear next step. For local businesses, validate profile details, service areas and genuine reviews.
Finally, test forms, calls and bookings. An SEO program cannot be managed responsibly if traffic grows while lead capture is broken.
Practical action plan
- Export indexed and excluded URL samples.
- Crawl the site and compare against the sitemap.
- Test mobile templates and Core Web Vitals.
- Map keywords to pages and identify overlap.
- Review trust, local and conversion signals.
- Rank fixes by impact, effort and risk.
Common mistakes to avoid
- Treating every Search Console exclusion as an error.
- Fixing low-impact metadata before security or indexing failures.
- Reporting an audit without owners, priorities or implementation steps.

Frequently asked questions
How often should a site be audited?
Monitor continuously and run a deeper review after major redesigns, migrations, security incidents or material strategy changes.
Should all 404s be redirected?
No. Redirect only when a genuinely relevant replacement exists. A clear 404 is better than an unrelated redirect.
Can an audit guarantee rankings?
No. It can reduce avoidable problems and identify opportunities; search visibility remains competitive and not guaranteed.
