Understanding Technical SEO

SEO, or Search Engine Optimisation, is the process of improving your website to increase its visibility when people search for products or services related to your business on search engines like Google. It’s vital because higher visibility in search results drives more organic traffic to your site, which can lead to more customers and higher sales.

There are three main types of SEO: on-page, off-page, and technical. You can read about them in another post by clicking here. In this blog, our main focus is on the third type of SEO services: technical SEO. Technical SEO is often overlooked but is crucial for laying a strong foundation for both on-page and off-page efforts. It involves optimising your website’s infrastructure to ensure search engines can crawl, index, and understand your site effectively. This includes enhancing site speed, ensuring mobile-friendliness, using SSL certificates for security, implementing structured data, and more. For instance, a fast-loading, secure, and mobile-friendly site can significantly improve your rankings and user experience.

Technical SEO is important because it helps search engines navigate and rank your site accurately. Imagine your website as a house. On-page SEO is the interior decoration and layout, off-page SEO is the neighbourhood and curb appeal, while technical SEO is the solid foundation and structure. Without a strong technical base, even the best content and backlinks won’t be as effective.

Incorporating technical SEO best practices ensures that your site not only meets the search engines’ criteria but also provides a seamless and enjoyable experience for users. This includes quick load times, easy navigation, and secure browsing. A well-optimised technical SEO strategy can lead to higher search rankings, more traffic, and ultimately, more conversions. In an era where users expect fast, reliable, and secure online experiences, technical SEO is more important than ever.

Types of Technical SEO

Crawlability and Indexability

Search engines use bots to crawl and index your website. Making sure your site is easily crawlable and indexable is essential. Use tools like Google Search Console to check how your site is being crawled. Set up a clear and logical site structure with a sitemap and robots.txt file to guide search engines. Fix any broken links or crawl errors as they can hinder indexing.

Site Speed Optimisation

Site speed is crucial for both user experience and SEO. Slow loading times can drive users away and hurt your rankings. Optimise images by compressing them without losing quality. Use browser caching and a content delivery network (CDN) to speed up load times. Minify CSS, JavaScript, and HTML to make your pages render faster. Google PageSpeed Insights can help you identify and fix speed issues.


With most users accessing websites via mobile devices, having a mobile-friendly site is a must. Implement responsive design to ensure your site works well on all screen sizes. Test your site’s mobile usability using Google’s Mobile-Friendly Test tool. Make sure buttons are easy to click and content is readable without zooming.

Secure Sockets Layer (SSL)

Security is vital for both users and search engines. An SSL certificate (HTTPS) ensures that data transmitted between your website and users is encrypted and secure. Google prefers secure sites, so having an SSL certificate can improve your rankings. Make sure all pages on your site are served over HTTPS to build trust with your audience.

Structured Data and Schema Markup

Structured data helps search engines understand your site’s content better. Implementing schema markup can enhance your search results with rich snippets, improving click-through rates. Use to find the right markup for your content, whether it’s articles, products, reviews, or events. Test your structured data with Google’s Rich Results Test tool.

XML Sitemaps

An XML sitemap is like a roadmap of your website that helps search engines find and index all your pages. Regularly update your sitemap to reflect changes and new content. Submit your sitemap to Google Search Console and Bing Webmaster Tools to ensure all pages are indexed correctly.

Canonical Tags

Duplicate content can confuse search engines and dilute your ranking power. Use canonical tags to indicate the preferred version of a page. This helps prevent duplicate content issues and consolidates link equity. Make sure your canonical tags are correctly implemented across your site.

Practical Tips and Insights

  • Conduct Regular Audits: Regularly audit your site to identify and fix technical issues. Tools like Screaming Frog, SEMrush, and Ahrefs can help.
  • Stay Updated: Keep up with the latest SEO trends and algorithm changes. Follow industry blogs, join SEO forums, and attend webinars.
  • Monitor Log Files: Analyse server log files to see how search engines are crawling your site. Look for patterns, errors, and areas for improvement.
  • Use Breadcrumbs: Enhance site navigation and help search engines understand your site’s structure with breadcrumb trails.
  • Voice Search Optimisation: Optimise for voice search by focusing on long-tail keywords and natural language queries.
  • Clean Code: Ensure your site’s code is clean and error-free. Validate your HTML, CSS, and JavaScript to avoid issues that could affect performance.
  • International SEO: If you target multiple countries, use hreflang tags to indicate language and regional targeting, helping search engines serve the correct version of your site.

Wrapping Up

Technical SEO is crucial for your website’s foundation. It ensures search engines can easily access, crawl, and index your content, which is vital for higher rankings. By improving site speed, mobile-friendliness, security, and structured data, you can significantly boost your site’s performance and visibility.

Regular audits are important to spot and fix issues early. Staying updated with algorithm changes keeps your technical SEO effective. A technically sound website offers a better user experience with faster load times, easy navigation, and secure browsing. Users are more likely to stay longer and convert when they enjoy your site.

A clean, easily understandable website is essential. Users expect quick load times and intuitive navigation. A slow or confusing site frustrates visitors, impacting satisfaction, bounce rate, and overall SEO performance.

Mobile-friendliness is critical. With much internet traffic from smartphones, your site must be optimised for mobile users. Google prioritises mobile-friendly sites, so ensuring responsiveness gives you a competitive edge. Mobile optimisation includes readable text without zooming, easy-to-click links, and quick load times on mobile networks.

A large percentage of people browse the internet on smartphones, and this trend is growing. Without mobile optimisation, you risk losing significant traffic. A seamless mobile experience keeps users engaged and encourages interaction, leading to higher conversion rates.

Security is crucial too. Implementing HTTPS encrypts data between your site and users, building trust and positively impacting your search rankings.

In my view, investing in technical SEO is one of the smartest moves you can make. It not only improves your search rankings but also enhances user satisfaction. A well-optimised site ensures that you are not just seen but also enjoyed and trusted by your visitors. Remember, a website that performs well technically is more likely to attract, retain, and convert users. This ultimately drives more traffic and boosts your business’s growth.
