Technical SEO Audit

In today’s competitive digital environment, visibility is everything. For your website to perform effectively in search engine results, it must be both discoverable and accessible by search engine bots. Content and backlinks often are in the spotlight because they are the ongoing elements of a smart SEO strategy.

However, it’s the unseen infrastructure of your website – the technical SEO elements including internal links – that play a pivotal role in long-term organic growth.

At Ditto Digital, our in-depth Technical SEO Audit Services will identify, analyse and fix the underlying technical issues that may be hindering your website’s performance in online search. And if consumers can’t find your website then that is preventing your business from increasing revenue and growing.

Whether your site is experiencing traffic drops, crawl errors, or a major redesign is on the horizon, a comprehensive SEO website audit will set the path for effective search engine optimization.

This audit is not just a checklist; it is a strategic, data-driven approach to improving the technical aspects of your website so that visibility, speed, crawlability, and overall health of the entire site are improved.

What is a Technical SEO Audit?

A technical SEO audit is a systematic review of your website’s underlying architecture, codebase and server configuration to ensure that search engines can crawl and index your content effectively. Unlike content or off-page SEO, technical SEO focuses on factors such as load speed, mobile usability, structured data, site architecture and security.

The audit ensures your website adheres to best practices laid out by Google and other search engines, while also enhancing the experience for users. By addressing these factors, your site stands a better chance of ranking well in search engine results pages (SERPs), thus improving your site’s performance in terms of visibility, more organic traffic, and ultimately, higher conversions.

Why Technical SEO Audits Matter

You can have the most compelling content based on thorough keyword research, and a strong backlink profile with high link equity. You can have the perfect meta descriptions on every page and blog post, but if search engines can’t crawl or index your site properly, if there are errors in your HTML code or internal linking issues, then you won’t appear in search results. Technical SEO is the foundation upon which every other SEO effort is built. Without it, your campaigns are running uphill.

Here are a few scenarios where technical SEO issues can severely impact your site:

• Slow site speeds leading to low engagement rate in the way users interact with your pages (high page bounce rate etc)
• Broken internal links causing crawl errors and wasted crawl budget
• Improperly configured redirects confusing search engines
• Mobile usability issues lowering SEO performance in rankings
• Duplicate content diluting search engine authority
• Missing or incorrect structured data limiting visibility in Google search rich results

Search engines like Google use over 200 ranking factors, many of which are technical. These include Core Web Vitals metrics, page speed scores and error status codes. A technical SEO analysis is necessary to provide the actionable insights that will ensure your website meets these technical criteria and improves your chances of ranking well.

Key Elements Included in an SEO Audit

Here at Ditto Digital, our bespoke technical SEO auditing services are tailored to your website. All websites vary and whilst SEO best practice is right for almost all websites, if you have a particularly large website (e.g. several thousand pages) then you may need a different approach.

Our technical SEO experts have over 15 years’ experience in all aspects of search engine optimization. As a specialist SEO agency we have the knowledge and skills, backed up by real-world experience, to deliver audit services that have a positive impact on website performance, search engine rankings and business revenue.

Our technical SEO audits are data-driven and prioritised for maximum impact. They come with a full SEO report, with prioritised SEO recommendations. We will discuss the report with you either face-to-face or via Teams/Zoom and, if required, will liaise with your web developers about all the technical aspects of the audit report.

Our SEO audit service involves a deep dive into the following key areas:

1. Website Crawlability and Indexation in Search Results

Our analysis ensures that search engines and their crawling software or bots can efficiently crawl and index your site without encountering barriers (such as external links or internal links pointing to non-existent pages).

• Robots.txt file analysis (including robots meta tag)
• XML sitemap validation
• Crawl budget optimisation
• Crawl error identification (404 errors, 500 errors, redirect chains)
• Review of noindex/nofollow meta tags
• Canonical tag implementation and review
• Pagination and infinite scroll checks

2. Site Architecture and URL Structure

A clean, logical site structure improves both user experience and a search engines efficiency so our technical audits will examine the following:

• Hierarchical navigation structure
• Consistent and SEO-friendly URL patterns
• Internal linking analysis
• Detection of orphan pages
• Breadcrumb navigation checks

3. Page Speed and Site Performance (Core Web Vitals)

Site speed is a major ranking factor and user experience booster. For that reason it is a key part of all our technical SEO audits.

• Performance testing using Google Lighthouse
• Largest Contentful Paint (LCP) assessment
• First Input Delay (FID) diagnostics
• Cumulative Layout Shift (CLS) measurement
• Image compression and format optimisation (e.g. use of WebP images)
• JavaScript and CSS minification
• Removal on unused JavaScript and CSS
• Server response time and hosting environment review

4. Mobile Usability

With mobile-first indexing, your site must perform perfectly on smaller screens so our technical SEO audit includes mobile optimisation checks for the following, which are reported in Google Search Console:

• Mobile responsiveness check
• Viewport configuration and scaling
• Font size and tap target assessments
• Mobile load time analysis
• Cross-device rendering checks

5. HTTPS and Site Security

Security is both a trust element and a ranking factor on search engine results pages (SERPS).

• SSL certificate validation
• Mixed content checks
• Secure redirect configuration (i.e. HTTP URL versions have permanent 301 redirects to the HTTPS version)
• HSTS and security header implementation
• Malware and blacklist scanning

6. Structured Data and Schema Markup

Technical SEO auditing also analyses structured data because the right structured data (schema markup) will enhance how your pages are understood by search engines and how they appear in search results. For instance, whether it will appear as a featured snippet or rich snippet or with a thumbnail image.

• Schema.org validation using Google’s Rich Results Test to ensure schema markup are correctly implemented
• Review of existing structured data (e.g., Product, FAQ, Organisation)
• Identify opportunities for rich snippets (e.g., Reviews or Events)
• Correcting JSON-LD syntax issues

7. International SEO (If Applicable)

If your business targets consumers in other countries then we specialise in international SEO – either for businesses with locations in both the UK and overseas, and also for UK-based businesses selling into other countries but without a physical base in those target countries.

We have experience with multi-lingual websites and overseas search engines. We know the best approach to reach an international audience via online search because we have run international campaigns and have data and case studies to show what we achieved.

The Technical Audit Process

Our technical site audit process is both meticulous and strategic, designed to give you clear, jargon-free recommendations and actionable insights to improve search engine visibility and drive inbound organic traffic. Essentially a roadmap for success in terms of search visibility and organic traffic.

Step 1: Discovery & Access

We begin with an onboarding session to understand your objectives, challenges and website history. Gaining access to tools like Google Search Console, Google Analytics, your CMS and hosting environment helps us perform a deep dive into your data – identifying how users interact with your website and how search engines access it.

In addition to analysing internal linking we can also analyse external links using our preferred proprietary software. Whilst external links (also known as off-site SEO) are not part of a website technical audit we can gain a more rounded picture of the current state of your website from a digital marketing perspective by doing a broad review of backlinks. This helps us understand how search engine crawlers view your website.

Step 2: Website Crawl & Diagnostic Review

We use industry standard tools such as Screaming Frog crawling software to analyse site structure. Or SEO PowerSuite, Ahrefs, SEMrush, and Google’s own tools – in particular GSC – combined with our extensive SEO expertise to perform a comprehensive crawl and technical scan of your entire website. In just the same way as search engines would do.

Step 3: Analysis & Impact Assessment

We organise findings by severity, categorising issues as high, medium or low priority. We also assess the potential SEO and UX impact of each issue, helping you focus on fixes that will deliver the most benefit.

It is not always possible to fix all technical SEO issues without significant changes to important aspects of a website. But in situations such as these we will work closely with your web developers to undertake the improvements that can be made within your budget.

Where required we can also recommend web developers to do any necessary technical fixes, user experience (UX) improvements and site speed updates.

Step 4: Custom Reporting

You will receive a fully bespoke technical SEO audit report including:

• An executive summary of the SEO audit with top-level insights
• Detailed explanations of each site audit issue
• Screenshots and examples, including site audit settings
• Step-by-step recommendations for improving, for instance, crawl budget, meta tags, structured data and Core Web Vitals.
• Priority levels and estimated implementation timelines

Step 5: Implementation Support (Optional)

We can either implement fixes on your behalf or work alongside your web developers, designers or third-party vendors to ensure seamless integration of all our recommendations where possible.
