Technical SEO Audit: Step-by-Step Guide


Technical SEO is a critical aspect of search engine optimization that focuses on enhancing a website’s technical aspects to improve its ranking and user experience. This involves optimising the infrastructure of a site so that search engines can crawl and index it more effectively. A technical SEO audit is a comprehensive evaluation of a website’s technical setup, aimed at identifying and fixing issues that could negatively impact its performance in search engine results. Performing such an audit is essential for ensuring a website’s visibility and user experience are optimised.

This guide provides an in-depth look at each step and the necessary tools for conducting a technical SEO audit.

What is Technical SEO?

Technical SEO involves optimising the technical elements of a website to improve its visibility in search engine results. This includes site architecture, URL structure, and the use of structured data.

Technical SEO refers to the process of optimizing a website’s infrastructure to enhance its visibility and ranking on search engines. It encompasses a range of activities from optimizing the site architecture to ensuring it is easily crawlable by search engines. Unlike content or on-page SEO, technical SEO focuses on the backend elements of your site, ensuring they meet the technical requirements set by search engines.


  • Implementing a responsive design for mobile optimization.
  • Setting up SSL for secure connections.
  • Optimizing the site’s loading speed.

Why is Technical SEO Important?

  1. Essential for Crawlers: It’s vital for allowing search engine crawlers to discover and index the right pages efficiently.
  2. Optimised Indexing: Ensures that Google can crawl and index your site according to your preferences, enhancing visibility.
  3. Improves User Experience: A technically sound website loads faster, navigates easier, and is generally more user-friendly.

Technical SEO is crucial because it helps search engines effectively crawl, index, and interpret your website without any issues. If search engines struggle to access and understand your site, your content won’t be displayed in search results as it should be, impacting your site’s traffic and performance.


  • A well-implemented technical SEO enhances user experience and site usability.
  • Increases the crawl efficiency for Googlebot, affecting how often and how thoroughly your site is indexed.
  • Helps prevent duplicate content issues which can dilute keyword relevance.

  • Before launching a new website.
  • After major updates to the website.
  • At least twice a year as a routine check.


  • Prior to a major website redesign.
  • Following the migration of a site to a new domain.

  • Tool Usage: Utilise tools like Google’s Structured Data Testing Tool for creating and validating schema markup.
  • Best Practices: Choose the right schema types and add relevant properties to enhance understanding.

Performing a technical SEO audit involves a systematic examination of a website to identify and rectify any potential issues affecting search engine visibility. Here’s how to conduct a technical SEO audit:

  1. Crawl Your Website: Use a technical SEO audit tool like Screaming Frog to identify crawl errors.
  2. Check for HTTPS Security: Ensure your site is secure with SSL certification.

  • Utilize XML sitemaps to ensure all pages are found by search engines.
  • Check for broken links to maintain link integrity.
  • Ensure redirect chains are minimized to improve load times.

Core Web Vitals

Core Web Vitals are crucial metrics established by Google to measure the health and performance of a website from a user experience perspective. They have become a significant part of Google’s ranking factors, emphasising the importance of delivering a superior online experience.

Core Web Vitals are a set of specific factors that Google considers important in a webpage’s overall user experience. They are part of Google’s “Page Experience” signals used to measure user satisfaction and include metrics such as Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).


  • LCP: Ensure the main content of a page loads within 2.5 seconds.
  • FID: Strive for a first input delay of less than 100 milliseconds.
  • CLS: Maintain a cumulative layout shift score less than 0.1.

Incorporating these elements into your technical SEO audit ensures your website aligns with best practices for SEO, ultimately improving its visibility and ranking in search engine results.

What are Core Web Vitals?

Core Web Vitals are a set of specific factors identified by Google as essential to a webpage’s user experience. These vitals include:

  • Largest Contentful Paint (LCP): Measures loading performance, specifically the time taken for the largest content element on the page to load.
  • First Input Delay (FID): Gauges interactivity, particularly the time from when a user first interacts with a page to the time when the browser responds to that interaction.
  • Cumulative Layout Shift (CLS): Assesses visual stability, focusing on how much visible content shifts during the loading process.

Why are Core Web Vitals Important?

Core Web Vitals are important because they directly influence a user’s experience on a website. High-performing sites in these metrics are likely to provide a more engaging and satisfying experience, leading to longer visit durations, lower bounce rates, and potentially higher conversion rates. Moreover, Google incorporates these metrics into its ranking algorithm, making them essential for search engine optimization. Websites that excel in these vitals are more likely to rank higher in search results, driving more traffic and engagement.
