What is a technical SEO audit?

Can search engines actually use your site?

A technical SEO audit, sometimes called an SEO website audit or health check, evaluates whether search engines can efficiently work through your most important pages. It’s written for decision-makers as much as developers: what’s wrong, why it matters and what to fix first.

  1. 01

    Discover

    Can search engines find your important pages?

  2. 02

    Crawl

    Can they access them efficiently?

  3. 03

    Understand

    Can they render and interpret the content?

  4. 04

    Index

    Are the right pages eligible to appear in search?

Our audit process

From crawl data to a clear plan.

  1. 01

    Technical discovery

    Your goals, platform, history, recent changes and known concerns.

  2. 02

    Crawl & data collection

    A full crawl plus Search Console, analytics and performance data.

  3. 03

    Indexation analysis

    What’s indexed, what isn’t, and whether that matches what should be.

  4. 04

    Performance review

    Loading, responsiveness, stability and mobile experience on key templates.

  5. 05

    Architecture analysis

    Structure, internal linking and how authority flows to important pages.

  6. 06

    Issue prioritisation

    Every finding rated by severity and business impact.

  7. 07

    Recommendations & roadmap

    Clear fixes, ownership and a sequence to implement them.

Prioritised by impact

Not every SEO error matters equally.

Crawling tools can flag hundreds or thousands of warnings. Exporting that report isn’t an audit. We review the findings, discard the noise and rank what’s left by the impact it has on your search performance and your business.

  1. Critical

    Priority 1

    May directly block crawling, indexing or important site functionality.

    e.g. key templates set to noindex

  2. High impact

    Priority 2

    Likely to materially affect search performance or user experience.

    e.g. redirect chains on core pages

  3. Medium

    Priority 3

    Worth addressing once critical priorities are resolved.

    e.g. important pages buried deep

  4. Low

    Priority 4

    Minor improvements and optimisation opportunities.

    e.g. missing image alt text

Deliverables

What you receive.

A clear, practical audit, written so leadership understands the priorities and developers know exactly what to change.

  • Technical SEO findings

    What we found, with evidence.

  • Prioritised issue list

    Ranked by severity and business impact.

  • Severity assessment

    Why each issue matters, in plain language.

  • Page & template examples

    Where each issue appears on your site.

  • Recommended fixes

    What to change to resolve each issue.

  • Developer-ready guidance

    Implementation notes your team can action.

  • Strategic SEO roadmap

    The order to tackle fixes and what follows.

  • Key opportunity summary

    The biggest wins, on a single page.

Technical SEO + your team

Findings your whole team can act on.

Technical SEO isn’t only a developer’s job. Fixes often involve SEO specialists, developers, designers and content teams, so we translate every finding into guidance each of them can use.

  • SEO specialists

    Priorities, rationale and how to validate fixes.

  • Developers

    Specific, technical implementation guidance.

  • Designers

    Template and navigation changes that affect structure.

  • Content teams

    Consolidation, duplication and on-page clean-up.

Example finding: illustrativeCritical

Product category pages are not indexable

Why it matters
Category pages drive most non-brand search demand but currently carry a noindex directive.
Where
Category template · all category URLs
Recommended fix
Remove the noindex directive from the category template and confirm the canonical points to the clean URL.

Core Web Vitals & performance

Fast enough to feel effortless.

Performance shapes both user experience and how efficiently search engines process your site. Passing Core Web Vitals alone doesn’t guarantee better rankings. It’s one part of overall technical and experience quality.

  • LCP

    Loading experience

    How quickly the main content appears.

  • INP

    Interaction responsiveness

    How quickly the page responds when people act.

  • CLS

    Layout stability

    Whether the page jumps around while loading.

  • Mobile

    Mobile experience

    How the site performs where most people browse.

Crawling & indexing

Where good pages quietly drop out.

Every page has to pass each stage before it can compete. If an important page fails early, its content may never get its full search opportunity, however good it is.

  1. Website01
  2. Discovery02

    Pages can drop out here due to: Orphaned or unlinked pages

  3. Crawling03

    Pages can drop out here due to: Blocked paths or crawl traps

  4. Rendering04

    Pages can drop out here due to: Content hidden behind JavaScript

  5. Indexing05

    Pages can drop out here due to: Noindex, duplicates, wrong canonicals

  6. Search eligibility06

Site migrations

Changing the site? Protect what it’s earned.

Redesigns and migrations are where hard-won search visibility is most often lost. A technical review before launch, or a recovery audit after, helps protect URLs, signals and traffic.

Planning a redesign? See our web design approach

Planning or recovering from

  • Website redesign
  • CMS migration
  • Domain migration
  • HTTPS migration
  • Major URL restructuring

Common risks

  • Broken redirects
  • Lost URLs
  • Incorrect canonicals
  • Internal link problems
  • Indexation loss

Large & ecommerce websites

More pages. More ways to go wrong.

Larger sites can face additional complexity, not every ecommerce site has these issues, but when they exist, they compound quickly.

  • 01

    Faceted navigation

  • 02

    Parameter URLs

  • 03

    Duplicate categories

  • 04

    Crawl budget efficiency

  • 05

  • 06

    Product availability

  • 07

    Large-scale internal linking

  • 08

    Canonicalisation

Audit questions

Questions about technical SEO audits.

01

What is a technical SEO audit?

A technical SEO audit is a structured review of how well search engines can discover, crawl, render and index your website (covering crawlability, indexability, architecture, performance, status codes, rendering and structured data) followed by prioritised recommendations.

02

How much does a technical SEO audit cost?

Our technical SEO audits start from $750 as a one-time engagement. The final price depends on the size and complexity of your site, its platform, the number of templates, existing issues and any international or multi-location setup.

03

How long does a technical SEO audit take?

It depends on the size and complexity of the website. Smaller sites can be audited relatively quickly, while large, ecommerce or international sites need more crawl time and analysis. We confirm a timeline once we understand the scope.

04

What does a technical SEO audit include?

It includes a review of crawlability, indexability, site architecture, technical performance and Core Web Vitals, on-page technical signals, redirects and status codes, JavaScript rendering where relevant and structured data: delivered as prioritised findings, recommended fixes, developer guidance and a roadmap.

05

How do I know if my website needs an SEO audit?

Common signs include a sudden traffic drop, important pages missing from search, a recent redesign or migration, slow performance, duplicate URLs, indexing warnings in Search Console, or SEO work that isn’t producing results.

06

Will you fix the issues found in the audit?

We can. Implementation isn’t included in the audit price unless it’s scoped, but we can work with your developers, implement fixes as part of an SEO engagement, or provide guidance for your team to deliver.

07

Can a technical SEO audit improve rankings?

An audit identifies technical issues that may be limiting your visibility. Fixing them can remove barriers to performance, but rankings depend on many factors (content, authority, competition and intent) so no audit can guarantee ranking improvements.

08

Do you audit ecommerce websites?

Yes. Ecommerce audits often include extra attention to faceted navigation, parameter URLs, duplicate categories, pagination, product availability and canonicalisation, where those issues apply to your site.

09

Should I audit my website after a redesign or migration?

Yes: ideally before launch as well as after. Redesigns and migrations commonly introduce broken redirects, lost URLs, incorrect canonicals and indexation loss, which are much easier to fix early.

10

How often should a technical SEO audit be performed?

A full audit makes sense before or after major site changes and periodically for larger or frequently updated sites. Between audits, ongoing monitoring helps catch new issues as they appear.
