Understanding the importance of a technical SEO audit
What is a technical SEO audit?
A technical SEO audit is a comprehensive analysis of the technical aspects of your website that influence its ranking on search engines such as Google, Bing, or Yahoo. This procedure ensures that your site is optimized for these engines, focusing on removing barriers to crawlability and indexation, which are essential for improving your visibility in Search Engine Results Pages (SERPs).
Why is it essential for optimizing your site?
Conducting a technical SEO audit is vital for optimizing your site, as it helps identify and fix issues that harm the quality and user experience of your site.
For example, a technical audit is useful for addressing issues such as:
- Issues related to title tags, meta descriptions, duplicate content, or internal linking, which reduce the visibility and relevance of your pages.
- 404 pages, hreflang errors, or canonical tag issues, which can compromise the consistency and reliability of your site.
- Slow loading times, Core Web Vitals issues, or mobile responsiveness problems that negatively impact visitor experience and retention.
By conducting a technical SEO audit, you significantly increase your site's performance and competitiveness, which translates into higher organic traffic, better conversion rates, and ultimately, more revenue.
Preparing for a technical SEO audit: tools and data to gather
Essential tools for a successful technical SEO audit
To conduct an effective technical SEO audit, certain tools are essential. They allow you to scan your website, detect issues, and suggest fixes. While many tools are available, here are the must-haves we recommend:
- Google Search Console: this free SEO tool from Google provides an overview of your site's indexation, security, mobile compatibility, loading speed, Core Web Vitals, HTML tags, and internal and external links.
- Ahrefs Webmaster Tools: free, this tool lets you conduct a thorough SEO audit, identifying over 100 potential issues related to technical performance, content, and backlinks, while also analyzing organic traffic and keywords.
- Screaming Frog SEO Spider: this paid tool (for crawling more than 500 URLs) crawls your site and collects data on URLs, titles, meta descriptions, canonical tags, redirects, and errors, among other things, to help resolve technical issues.
- Google PageSpeed Insights: free, this tool measures your site's loading speed on both mobile and desktop, providing a performance score and optimization recommendations.
Collecting the data needed for the audit
A technical SEO audit involves gathering information on various aspects of your site, including:
- Indexation: Make sure your pages are properly indexed, accessible to crawl bots, compliant with Google's guidelines, and free from duplication, canonicalization, or pagination issues.
- Security: Check that the HTTPS protocol is in use, that your SSL certificate is valid, that your robots.txt and sitemap.xml files are properly configured, and that there is no malware, phishing, or spam.
- Loading speed: Make sure your site loads quickly on all devices, meets Core Web Vitals criteria, and optimize images, reduce HTTP requests, and use caching and compression.
- Mobile compatibility: Check that your site adapts to different screen sizes with a responsive design, with no elements that harm the mobile user experience such as pop-ups and interstitials.
- Site structure: Ensure a logical architecture, descriptive URLs, a consistent heading hierarchy, good internal linking, and no broken links or 404 errors.
- Content: Check the quality, relevance, and originality of your content, keyword optimization, proper use of title tags, meta descriptions, Hn tags, alt attributes, and avoid duplicate or thin content.
- Backlinks: Ensure a diverse and high-quality backlink profile, with links from trusted sites, while avoiding toxic links and using descriptive anchor text.
This data forms the essential foundation for a thorough technical SEO audit, making it possible to identify and improve your site's weak points for better organic search performance.
Conducting a technical SEO audit: step by step
1. Analyzing site indexability and accessibility
Indexability and accessibility are fundamental in a technical SEO audit, as they allow you to check whether a website is easily crawled and indexed by search engines. It is also crucial to ensure that pages are accessible to users.
Tools such as Google Search Console, Ahrefs Webmaster Tools, or Screaming Frog SEO Spider are essential for:
- Monitoring the number of indexed pages, identifying those excluded from indexation and the reasons for these exclusions (for example, due to noindex tags, canonical tags, the robots.txt file, etc.).
- Reviewing the HTTP status of pages to fix errors (404, 500, etc.) that block access to content for users and bots.
- Checking the presence and configuration of the robots.txt file, which guides crawl bots.
- Verifying the presence and configuration of the sitemap.xml file, which is essential for providing search engines with a map of your site's pages and their update frequency.
2. Checking site architecture and internal linking
Architecture and internal linking play a key role in optimizing your site structure and improving navigation for users and search engines. These elements influence how your pages are organized and connected to each other.
Use tools such as Screaming Frog SEO Spider or Ahrefs Site Explorer to:
- Analyze page depth, to minimize the number of clicks required from the homepage.
- Check URL length and readability, to avoid overly complex or non-descriptive addresses.
- Review the consistency and relevance of Hn tags, which help organize content and signal the structure and priority topics of your pages to search engines.
- Assess the quantity and quality of internal links, which are essential for connecting your content and effectively distributing link equity to your most strategic pages.
3. Evaluating the site's technical performance
Technical performance is a determining factor in delivering a good user experience and boosting your website's search rankings. These criteria include loading speed, security, mobile compatibility, and Core Web Vitals.
To measure these, tools such as Google PageSpeed Insights, Google Mobile-Friendly Test, Google Search Console, or Ahrefs Webmaster Tools are needed to:
- Measure loading speed on mobile and desktop, and identify the elements slowing down your site (such as images, scripts, CSS, etc.).
- Check how well your site adapts to mobile devices and fix display issues.
- Evaluate your site's compliance with Core Web Vitals, Google's metrics for measuring performance and user satisfaction.
- Confirm the use of the HTTPS protocol, ensuring data security and privacy.
4. Mobile optimization and cross-device compatibility
Mobile optimization and cross-device compatibility are crucial for delivering a good user experience and improving SEO.
To adapt to increasingly mobile user behavior and optimize your site, resources such as Google Mobile-Friendly Test, Google Search Console, Ahrefs Site Audit, or Screaming Frog SEO Spider are useful for:
- Checking that your site is accessible and functional on mobile devices.
- Ensuring your site has a responsive design that automatically adjusts to different screen sizes and orientations.
- Avoiding elements that can harm the mobile user experience, such as intrusive pop-ups, fonts that are too small, or buttons that are too close together.
- Checking the use of hreflang tags, which are important for specifying the language and country targeted by your content, and for avoiding duplication or incorrect redirect issues.
5. Security and HTTPS protocols
Security and HTTPS protocols play a crucial role in protecting your website and users from malicious attacks. They are essential for building trust and credibility, ensuring the confidentiality and integrity of the data exchanged. These preventive measures are indispensable for guarding against hacking, phishing, and spam risks.
To assess and strengthen these aspects, it is recommended to use tools such as Google Search Console, Ahrefs Site Audit, or SSL Labs. These tools will help you:
- Verify the use of the HTTPS protocol, which ensures a secure connection and has a positive impact on your Google ranking.
- Confirm the validity of your SSL certificate, a mark of authenticity and reliability that is required for HTTPS to be activated.
- Ensure the proper configuration of your robots.txt and sitemap.xml files, which are essential for guiding search engines on which pages to crawl and index, and which can also contain security directives.
- Identify any malware, phishing, spam, or deceptive content that could affect your site's reputation and ranking, detectable via Google Search Console or Ahrefs Site Audit.
6. Checking Meta tags, Hn tags, and content optimization
Meta tags, Hn tags, and content optimization are critical for improving your website's relevance and visibility on search engines. They help structure and describe your content effectively, capturing users' attention.
It is recommended to use tools such as Screaming Frog SEO Spider, Ahrefs Site Audit, or Google Search Console to:
- Analyze the presence and quality of your title and meta description tags, which should be unique, descriptive, relevant, and engaging for each page of your site.
- Review the structure of your Hn tags, which are key for presenting the topic and hierarchy of your content to search engines. Use a single H1 tag per page with the primary keyword, and use H2, H3, etc. tags that include secondary keywords.
- Ensure your content is original, relevant, informative, and useful to users. Avoid any duplicate, thin, hidden, or over-optimized content.
- Optimize your content around primary and secondary keywords, incorporating synonyms and variations, to improve your organic search ranking.
This approach will help you conduct an effective technical SEO audit and identify areas for improvement to optimize your online presence.
