Quick Answer

An SEO audit systematically checks your website's technical health, on-page optimisation, content quality, backlink profile, and local presence. For Australian businesses, it should also cover Google Business Profile, local directories, and AI search visibility. Run one every 6 months minimum.

What Is an SEO Audit?

An SEO audit is a health check for your website's search visibility. It identifies what's working, what's broken, and what opportunities you're missing.

Think of it like a building inspection before you renovate. You wouldn't start knocking down walls without checking the foundation first. Similarly, spending money on content or link building without auditing your technical SEO is a common (and expensive) mistake.

According to Google's SEO Starter Guide, the fundamentals of search optimisation begin with ensuring Google can find, crawl, and index your pages correctly. An audit verifies all of this.

Technical SEO Checklist

Technical SEO is the foundation. If Google cannot crawl and index your site properly, no amount of content or link building will help. According to Google's crawling and indexing documentation, these are the critical elements to check:

Site is accessible to Googlebot

Check robots.txt isn't blocking important pages. Verify in Google Search Console under 'Settings > Crawling'.

XML sitemap exists and is submitted

Submit your sitemap via Google Search Console. Ensure it's up to date and only includes indexable pages.

HTTPS is enabled across all pages

All pages should load over HTTPS with no mixed content warnings. Google has confirmed HTTPS as a ranking signal.

Page speed scores are acceptable

Test with Google PageSpeed Insights. Aim for a Performance score above 90 on mobile. Core Web Vitals (LCP, INP, CLS) should pass.

Mobile-friendly design

Google uses mobile-first indexing. Test with Chrome DevTools mobile emulation or Google's Mobile-Friendly Test.

No duplicate content issues

Use canonical tags to tell Google which version of a page is the 'original'. Check for www vs non-www and HTTP vs HTTPS duplicates.

Clean URL structure

URLs should be descriptive, use hyphens (not underscores), and avoid unnecessary parameters.

Proper redirects (no chains or loops)

301 redirects should go directly to the final URL. Redirect chains slow crawling and dilute link equity.

No broken links (404 errors)

Use Screaming Frog or Google Search Console to find and fix broken internal and external links.

Structured data / Schema markup

Implement relevant schema types (LocalBusiness, FAQPage, Article). Validate with Google's Rich Results Test.

Core Web Vitals matter more than ever

Google's Core Web Vitals (LCP, INP, CLS) are confirmed ranking signals. In 2024, Google replaced FID with INP (Interaction to Next Paint) as the responsiveness metric. Ensure your site passes all three thresholds.

On-Page SEO Checklist

On-page SEO ensures each individual page is optimised for its target keyword. According to Moz's on-page SEO guide, these are the essential elements:

Title tags are unique and under 60 characters

Include your primary keyword naturally. Each page needs a unique title that accurately describes its content.

Meta descriptions are compelling and under 160 characters

Write descriptions that encourage clicks. Include a call to action and your target keyword.

One H1 tag per page with primary keyword

The H1 should clearly describe the page's topic. Only use one H1 per page.

Logical heading hierarchy (H1 > H2 > H3)

Use headings to structure content logically. Don't skip levels (e.g., H1 directly to H3).

Images have descriptive alt text

Alt text helps Google understand images and improves accessibility. Describe what the image shows.

Internal links connect related pages

Link to relevant pages on your own site using descriptive anchor text. This helps Google understand your site structure.

External links to authoritative sources

Linking out to reputable sources signals trustworthiness and provides value to readers.

URL includes target keyword

Keep URLs short, descriptive, and keyword-rich. Avoid generic URLs like /page-1 or /post-12345.

Content & E-E-A-T Audit

Google's helpful content guidelines emphasise E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness. This is especially important for YMYL (Your Money or Your Life) topics.

Local SEO Audit (Australian-Specific)

For Australian businesses serving local customers, local SEO is often the highest-ROI area to optimise. According to Moz's local SEO guide, these factors drive local search rankings:

Google Business Profile is claimed and verified

This is non-negotiable for local SEO. Ensure your GBP is complete with accurate NAP (Name, Address, Phone), hours, categories, and photos.

NAP consistency across the web

Your business name, address, and phone number must be identical everywhere — your website, GBP, Yellow Pages, True Local, and all directories.

Listed on key Australian directories

Ensure listings on Yellow Pages (yellowpages.com.au), True Local, Yelp Australia, Hotfrog, and industry-specific directories.

Location pages for each service area

If you serve multiple cities (e.g., Sydney, Melbourne, Brisbane), create dedicated pages with unique content for each location.

Reviews strategy in place

Actively encourage Google reviews from customers. Respond to all reviews — positive and negative — promptly and professionally.

Local schema markup implemented

Add LocalBusiness schema with your address, phone, opening hours, and service area to help Google understand your local relevance.

Australian-specific content signals

Use Australian English (optimise, not optimize), mention Australian cities, reference local regulations, and price in AUD.

AI Visibility / GEO Audit (New for 2026)

With Google's AI Overviews, ChatGPT search, and Perplexity now answering queries directly, your content needs to be optimised for AI retrieval as well as traditional search. This emerging discipline is sometimes called Generative Engine Optimisation (GEO).

According to Search Engine Journal's analysis of AI Overviews, the key factors for AI visibility include:

Clear, concise answers near the top of pages

AI systems prefer content that directly answers questions in the first few paragraphs. Use 'Quick Answer' boxes or summary sections.

Structured content with clear headings

Well-organised content with descriptive H2/H3 headings is easier for AI to parse and cite.

Authoritative sourcing and citations

AI systems tend to surface content that cites authoritative sources and demonstrates expertise.

FAQ sections with schema markup

FAQ content structured with FAQPage schema gives AI systems clear question-answer pairs to reference.

Brand mentions and entity recognition

Build your brand's presence across the web so AI systems recognise your business as an authority in your space.

Frequently Asked Questions

How often should I run an SEO audit?

Run a comprehensive audit every 6 months, with lighter monthly health checks using Google Search Console. After major website changes, algorithm updates, or sudden traffic drops, run an immediate audit.

Can I do an SEO audit myself?

Yes — basic audits are achievable with free tools like Google Search Console, PageSpeed Insights, and Screaming Frog (free for up to 500 URLs). For deeper competitive analysis, content strategy, and technical issues, a professional audit provides significantly more value.

What tools do I need for an SEO audit?

Essential free tools: Google Search Console, Google Analytics 4, PageSpeed Insights, and the Lighthouse browser extension. Paid tools like Ahrefs, Semrush, or Screaming Frog provide deeper insights into backlinks, keyword rankings, and large-scale crawling.

How long does a full SEO audit take?

A basic DIY audit takes 2-4 hours for a small website. A comprehensive professional audit for a medium-sized site (50-200 pages) typically takes 1-2 weeks, including analysis and a prioritised action plan.

What is the most important part of an SEO audit?

Technical SEO — because if Google cannot crawl and index your pages, nothing else matters. After that, content quality and search intent alignment are the biggest factors influencing rankings.
