Website SEO Audit Checklist: What to Check Before Optimisation

A website SEO audit checklist checks technical health, crawlability, indexation, content, on-page signals, links, analytics and conversion paths before optimisation. SEOGeelong.au uses these checks to identify issues, prioritise actions and connect findings with SEO Audits, Technical SEO, On-Page SEO and Web Analytics.

What Does a Website SEO Audit Check?

Website SEO audits check whether search engines can access, understand and evaluate a website, while also checking whether visitors can use it and take the intended action.

A complete audit brings together technical SEO, on-page SEO, content quality, links and Web Analytics. It connects search engine visibility with user experience, organic search performance and business outcomes.

The review can reveal crawl errors, indexation problems, content gaps, weak internal linking and measurement issues. These findings provide a practical base for SEO recommendations.

What to Check Before the SEO Audit Begins

Before an SEO audit begins, the audit scope must reflect the business goals, audience and website history. Clear access and context help us separate important issues from low-priority technical warnings.

We use the following preparation checks to establish what the website needs to achieve and what evidence is available.

Business goals should identify the actions that organic search needs to support.

Target audience should describe the people, needs and questions the website serves.

Target keywords should align with relevant services, products and search intent.

Website access should include the systems needed to inspect pages, settings and performance.

Google Search Console should be available for indexation, search queries and crawl information.

Google Analytics should be available for organic traffic, engagement and conversion data.

Website migration history should record redesigns, domain changes, platform moves and major URL changes.

What to Check During the Technical SEO Review

A technical SEO review checks whether search engines can crawl, process and index important pages. We also assess website performance and mobile usability because technical barriers can affect both visibility and page experience.

Each item should be checked in context. A warning matters most when it affects valuable pages, user access or the website’s ability to support search intent.

Crawlability should allow search engines to reach important pages without unnecessary barriers.

Indexability should be checked for unwanted exclusions, indexation gaps and incorrect noindex directives.

Robots.txt should allow useful crawling and avoid blocking important resources or page groups.

An XML sitemap should contain the canonical URLs that the website wants search engines to discover.

Each important page should use a suitable canonical URL and consistent canonical tags.

HTTP status codes should identify working pages, missing pages and server problems accurately.

Redirects should lead users and search engines to the correct destination without broken redirect chains.

Structured data, Core Web Vitals and mobile usability should be reviewed as part of website performance and page experience.

Which On-Page and Content Signals Need Review?

On-page and content checks review whether each important page matches search intent, communicates its subject clearly and gives users a complete answer.

A content audit should examine title tags, meta descriptions and heading hierarchy. These signals help users and search engines understand the page topic.

We also review keyword targeting, content quality, duplicate content, internal linking and image alt text. The aim is to identify useful content gaps and improve the connection between related pages.

How to Check Links, Authority and Search Visibility

Link checks show how pages connect within the website and how external websites refer to it. We assess links for usefulness, relevance and their role in organic visibility.

The review should combine link data with competitor search results. This helps distinguish a technical linking problem from a broader content or authority opportunity.

Internal links should connect related pages and help users reach important content.

Backlinks should be reviewed for relevance, quality and their connection to the website’s subject.

Referring domains should be assessed to understand the range of websites linking to the domain.

Link relevance should be considered alongside the page topic and surrounding content.

Broken links should be located and corrected where they interrupt user journeys or discovery.

Anchor text should describe the destination naturally and support clear navigation.

Organic visibility should be compared across important pages, topics and search results.

Competitor search results should be examined for content coverage, page purpose and linking patterns.

What to Check in Web Analytics Before Optimisation?

Web Analytics checks show which pages attract organic visitors, what those visitors do and whether measurement captures meaningful business actions.

Google Analytics and Google Search Console provide different views of performance. We compare them with landing page data, engagement signals and conversion data to understand the customer journey.

Conversion tracking, goal tracking and attribution should reflect the actions that matter to the business. Without reliable measurement, optimisation priorities can favour visits while overlooking valuable outcomes.

How to Prioritise SEO Audit Findings After the Review

SEO audit findings should be prioritised by their business impact, search impact and implementation effort. A clear order turns technical issues into an actionable optimisation roadmap.

We group related findings so the team can address root causes and avoid disconnected fixes. The final SEO recommendations should explain the issue, its effect and the next practical action.

Business impact identifies whether the issue affects leads, sales, trust or important customer journeys.

Search impact considers whether the issue limits crawling, indexation, rankings or organic visibility.

Implementation effort shows the work, access and coordination needed to apply the recommendation.

Technical debt highlights older issues that may make future optimisation harder.

Related issues should be grouped so one fix can improve several affected pages.

Urgent risks should be separated from improvements that can be planned later.

The optimisation roadmap should assign clear actions to the relevant website owner or team.

Which SEO Audit Problems Should Raise a Red Flag?

SEO audit problems should raise a red flag when they prevent important pages from being crawled, indexed, understood or measured. These issues can affect search visibility and business decisions at the same time.

Red flags need context, but each one deserves prompt investigation before wider optimisation work begins.

Noindex directive on a page that should appear in organic search.

Blocked crawl preventing search engines from reaching valuable content or resources.

Indexation gap between important published pages and pages available in search results.

Broken redirects, duplicate pages or missing conversion tracking affecting users, visibility or reporting.
