Technical SEO Explained: The Secret Behind Successful Websites

In the vast universe of the internet, where countless web pages orbit in the digital expanse, how can you ensure that your website stands out? How can you make sure your site shows up in search results, ideally on the first page where it can command the attention of users? 

The answer to these questions lies in the power of Search Engine Optimisation, or SEO. 

SEO is the process of optimising a website to improve its visibility in search engine results pages (SERPs), effectively guiding more users to your site.

At the core of this complex process is a subset called Technical SEO. This aspect of SEO is often perceived as mystifying, a realm reserved for the technologically adept. However, understanding and implementing Technical SEO is crucial for any website aiming to achieve higher page ranking and visibility. It’s the secret sauce that influences how search engines crawl and index your site, ultimately determining your website’s fate in the digital world.

Technical SEO revolves around various components. This includes improving page loading times to enhance user experience, using hreflang tags for multilingual websites, setting up canonical URLs to prevent duplicate content issues, and ensuring that your site is secure with an SSL certificate. These elements, among others, play significant roles in how search engines understand and rank your web pages.

One might compare Technical SEO to the inner workings of a watch. It might be hidden from sight, but its precise mechanisms are vital for the watch to function correctly. Similarly, the aspects of Technical SEO, like XML sitemaps, internal linking, and the proper use of Google Search Console, all contribute to a well-functioning, easily navigable, and user-friendly website.

However, the realm of Technical SEO isn’t just about setting things up and forgetting about them. Regular SEO audits are necessary to ensure that everything is working as it should and to make necessary adjustments. For instance, Google’s mobile-friendly test can help you determine if your site is optimised for mobile devices – a crucial ranking factor in today’s mobile-first world.

In this blog post, we will unravel the mysteries of Technical SEO, exploring how it can give your website the competitive edge. We’ll delve into how you can conduct a comprehensive technical SEO audit, the importance of factors like page loading times, and how to resolve common issues such as duplicate content.

Understanding Technical SEO

In the complex world of digital marketing, Technical SEO can be likened to the foundation of a house. Just as a strong foundation is crucial to a house’s stability and longevity, so is Technical SEO to a website’s visibility and ranking. But what exactly does Technical SEO mean?

Technical SEO refers to the process of optimising the infrastructure of your website. This is done to help search engine spiders crawl your site more efficiently, and index your web pages accurately, thereby improving your site’s visibility in search results. It’s about making your website’s structure search-engine friendly, and it encompasses everything from site speed to security, mobile optimisation to structured data, and much more.

While On-Page SEO focuses on content and keywords, and Off-Page SEO concerns itself with backlinks and external signals, Technical SEO is all about the nitty-gritty details that make your website easier for search engines to understand. It involves several components, each playing a vital role in enhancing your website’s overall SEO health.

For instance, consider page loading times. A faster-loading website not only provides a better user experience but is also favored by search engines. Slow-loading pages can frustrate users, potentially leading to higher bounce rates and lower click-through rates (CTR), both of which can negatively impact your SEO.

Another aspect is the use of canonical URLs. These are used to tell search engines that certain similar URLs are actually one and the same. This helps avoid duplicate content issues, as search engines understand which version of the page to index and rank.

Technical SEO also deals with the security of your website. Implementing an SSL certificate, for example, switches your site to HTTPS, encrypting data and making your website more secure for visitors. Search engines favor secure sites, and having HTTPS can give you a ranking boost.

The use of XML sitemaps, internal linking strategies, and hreflang tags for multilingual websites are other facets of Technical SEO. Each of these components helps search engines better understand your site structure and content, enhancing your visibility and ranking in search results.

Finally, tools like Google Search Console can provide valuable insights into your site’s performance and identify potential issues for you to address. Regular SEO audits using these tools are crucial to maintaining and improving your technical SEO efforts.

The Pillars of Technical SEO

Like any sturdy structure, Technical SEO stands on several crucial pillars. Each one plays a vital role in ensuring your website is easily accessible, understandable, and indexable by search engines. Let’s delve into these pillars, explaining what they are and why they’re crucial for your website’s success.

  • Website Structure and Navigation: A well-structured website is easier for both users and search engines to navigate. A logical hierarchy, clear navigation menus, and a consistent URL structure make it easier for search engines to understand your site and for users to find what they’re looking for.
  • XML Sitemaps: An XML sitemap is a roadmap to all your important pages. It helps search engines discover and crawl your site’s content, especially if your site is large or has pages that aren’t easily discovered through links. Submitting your sitemap through Google Search Console can expedite the indexing process.
  • Robots.txt File: This file tells search engines which pages or sections of your site they should or shouldn’t crawl. It’s a way of directing search engine spiders, ensuring they focus on your most important pages and avoid areas of your site that aren’t relevant to your SEO efforts.
  • URL Structure: URLs that are short, descriptive, and include relevant keywords are more easily understood by search engines and users. Canonical URLs can be used to specify the “preferred” version of a page, preventing duplicate content issues.
  • Page Loading Times: Slow-loading pages can harm user experience and your site’s ranking. Optimizing images, leveraging browser caching, and reducing server response time are a few strategies to improve page loading times.
  • Mobile Optimisation: With more and more users browsing on mobile devices, it’s crucial to have a mobile-friendly website. Google’s Mobile-Friendly Test can help you determine if your site is properly optimized for mobile viewing.
  • HTTPS and SSL Certificate: HTTPS, enabled by an SSL certificate, ensures data on your site is securely transmitted. Since search engines prioritize secure sites, migrating from HTTP to HTTPS can give your site a ranking boost.
  • Structured Data and Schema Markup: These are snippets of code that help search engines better understand the content on your page. They can also enhance your search result listings with rich snippets, increasing visibility and click-through rates.
  • Internal Linking: Internal links help spread link equity around your site, and they assist search engines in understanding the content and context of your pages. A good internal linking strategy can improve your site’s SEO.
  • Hreflang Tags and International SEO: If your website serves multiple languages or regions, hreflang tags help search engines understand which language you’re using on a specific page, so the correct version can be served to users.
  • SEO Audits: Regular audits help you monitor your website’s health, identify issues, and make necessary improvements. Tools like Google Search Console can be instrumental in conducting these audits.
  • Duplicate Content Issues: Duplicate content can confuse search engines and may lead to a ranking drop. Implementing canonical URLs and managing dynamic parameters can help resolve these issues.
  • Crawlability and Indexability: Ensuring that search engines can easily crawl and index your site is crucial. This involves several of the elements above, such as a clear website structure, a useful robots.txt file, and effective use of XML sitemaps.


Each of these pillars contributes to the overall strength and effectiveness of your website’s Technical SEO. By understanding and implementing these elements, you’ll be well on your way to creating a site that’s both user-friendly and search-engine-friendly.

Website Speed and Performance

The digital age has bred a culture of instant gratification where speed and efficiency reign supreme. The same principle applies to your website; the faster it loads, the better the user experience. This is where website speed and performance come into play in the realm of Technical SEO.

Website speed is crucial because it directly impacts user experience. Slow-loading web pages can lead to high bounce rates as visitors are likely to leave if they find themselves waiting too long for a page to load. A delay of just a few seconds can result in significant drops in user engagement, conversions, and ultimately, your bottom line.

Moreover, search engines understand this user behavior. Google, in particular, has made it clear that page loading times are a ranking factor for both desktop and mobile searches. Faster-loading websites are favored by Google’s algorithm, and they’re likely to rank higher in search results compared to their slower counterparts.

So, how can you improve your website’s speed and performance?

  • Optimise Images: High-resolution images can significantly slow down your page loading times. Compress and optimise images for the web without compromising their quality to speed up your load times.


  • Leverage Browser Caching: Browsers can cache a lot of information, so when a user revisits your site, the browser doesn’t have to reload the entire page. Utilize this feature to improve loading speed for returning visitors.


  • Reduce Server Response Time: Your server response time is affected by the amount of traffic you receive, the resources each page uses, the software your server uses, and the hosting solution you use. Identify and fix any bottlenecks to ensure a swift server response time.


  • Enable Compression: Use a software application for file compression, like Gzip, to reduce the size of your CSS, HTML, and JavaScript files that are larger than 150 bytes.


  • Minimise HTTP Requests: Each element (image, script, or stylesheet) on your page can generate an HTTP request. The more on-page components, the longer it takes for the page to render. Reduce these components and streamline your site for speed.


  • Use a Content Delivery Network (CDN): CDNs can help distribute the load of delivering content by storing a cached version of your site in multiple geographical locations. This means users get served content from a location closer to them, speeding up page load times.


  • Prioritise Above-the-Fold Content (Lazy Loading): This technique involves loading only the essential sections of your webpage first (what the user sees without scrolling), and then loading the rest as the user scrolls down.


Tools like Google’s PageSpeed Insights or other third-party tools like GTmetrix can help you analyse your website’s speed and identify areas for improvement. They provide comprehensive reports and actionable recommendations to enhance your site’s performance.

Remember, improving your website’s speed and performance is not a one-time task but an ongoing process. Regular audits and optimisations are necessary to ensure your website stays quick and responsive, offering the best possible user experience, and a higher likelihood of ranking well in search results.

Mobile Friendliness

In today’s digital age, the majority of internet users access the web through their mobile devices. In fact, as of May 2023, people using mobile devices contribute to over half (55%) of all website traffic. This significant shift in browsing behavior has led Google to adopt a mobile-first indexing approach, where the mobile version of a website is considered the primary version for ranking purposes. This change underscores the importance of mobile optimisation in the realm of Technical SEO.

Mobile friendliness, simply put, is the practice of ensuring your website looks and performs well on mobile devices. A mobile-friendly website not only provides a seamless user experience on smartphones and tablets but also positively impacts your site’s SEO performance. Given the increasing reliance on mobile devices, it’s crucial to make sure your site is optimized for mobile viewing.

Here are some key factors to consider when optimizing your website for mobile devices:

  • Responsive Design: A responsive design ensures that your website automatically adapts to the screen size and orientation of the device it’s being viewed on. This eliminates the need for separate mobile and desktop versions of your site, making it easier to manage and maintain.


  • Touchscreen Navigation: Mobile users navigate primarily by tapping and swiping on touchscreens. Ensure that your site’s buttons, links, and other interactive elements are large enough and spaced well apart to accommodate for touch-based navigation.


  • Page Loading Speed: Mobile devices often have slower internet connections than desktops, making it even more important to optimise your site for fast loading times. Apply the same principles discussed in the “Website Speed and Performance” section to optimise your site for mobile performance.


  • Legible Text and Readable Fonts: Mobile devices have smaller screens, so it’s essential to use easily readable fonts and font sizes, ensuring that users don’t have to zoom in to read your content.


  • Optimised Media: Images, videos, and other media elements should be optimized for mobile devices to ensure they load quickly and display correctly on smaller screens.


  • Avoid Flash and Pop-ups: Flash is not supported by most mobile devices, and pop-ups can be intrusive and frustrating on small screens. Avoid using these elements to create a smoother mobile experience.


  • Test on Multiple Devices: With a vast array of mobile devices available, it’s crucial to test your website on various screen sizes, resolutions, and operating systems to ensure a consistent user experience.


One of the best ways to evaluate your site’s mobile friendliness is to use Google’s Mobile-Friendly Test. This tool analyses your site and provides a report detailing any issues and recommendations for improvement. Additionally, Google Search Console offers a mobile usability report that can help you identify and fix mobile-specific issues.

By prioritising mobile friendliness, you’ll not only cater to the growing number of mobile users but also improve your website’s search engine rankings. In a world where mobile browsing is becoming the norm, optimising your site for mobile devices is no longer optional; it’s a necessity.

HTTPS and Website Security

In an increasingly interconnected world, ensuring the security and privacy of user data is paramount. This is where HTTPS and website security come into play. HTTPS (Hypertext Transfer Protocol Secure) is an extension of the standard HTTP protocol that encrypts data transmitted between a user’s browser and the website they are visiting. Adopting HTTPS and maintaining strong website security measures is not only essential for protecting sensitive information but also plays a significant role in Technical SEO. Here’s why it matters:


  • Data Security and User Trust: With cyber threats and data breaches on the rise, users are becoming more cautious about sharing their personal information online. HTTPS encrypts the data transmitted between a user and your website, safeguarding it from potential eavesdropping or tampering. When users see the padlock symbol and “https://” in the address bar, it instills trust and confidence in your website, improving the overall user experience.


  • Ranking Boost: Google considers website security as a ranking factor in its search algorithm. Secure websites that use HTTPS are more likely to receive a ranking boost compared to their non-secure counterparts. By implementing HTTPS, you signal to search engines that you prioritize the privacy and security of your users, potentially leading to improved search engine visibility and higher rankings.


  • Browser Warnings: Modern browsers, such as Google Chrome, display warnings to users when they visit non-secure HTTP websites. These warnings may deter users from accessing your site or raise concerns about its legitimacy. By switching to HTTPS, you avoid these warning messages, providing a smoother and more seamless browsing experience for your users.


  • E-commerce and Transactions: If your website handles e-commerce transactions or involves the transmission of sensitive information (such as credit card details or login credentials), using HTTPS is essential. It protects the integrity of the data and reduces the risk of interception or unauthorised access during transmission, establishing a secure environment for online transactions.


To enable HTTPS on your website, you’ll need to obtain an SSL (Secure Sockets Layer) certificate from a trusted certificate authority. This certificate verifies your website’s identity and establishes a secure connection with your visitors’ browsers. Additionally, it’s important to ensure that all internal links, images, and resources are updated to use the HTTPS protocol to maintain consistency and avoid mixed content warnings.

By prioritising website security, implementing HTTPS, and maintaining strong security practices, you not only protect your users’ data but also enhance your website’s trustworthiness, search engine visibility, and overall Technical SEO performance.

Structured Data and Schema Markup

In the vast landscape of the internet, search engines strive to understand the content and context of web pages to deliver the most relevant results to users. This is where structured data and schema markup come into play. 

Structured data refers to a standardised format for providing information about a webpage and its content. Schema markup, on the other hand, is a specific vocabulary or code that can be added to a webpage to help search engines interpret and understand its content better. Incorporating structured data and schema markup into your website offers several benefits in terms of Technical SEO. Let’s explore why they matter:


  • Enhanced Search Results: Schema markup enables search engines to create rich snippets, which are more visually appealing and informative search results. By adding structured data to your website, you provide search engines with additional context about your content, such as reviews, ratings, pricing, events, and more. These rich snippets can significantly improve the visibility and click-through rates (CTR) of your search results, attracting more users to visit your site.


  • Improved Knowledge Graph Presence: The Knowledge Graph is a knowledge base used by search engines to enhance search results with additional information. By incorporating structured data, you increase the chances of your website’s content being featured in the Knowledge Graph. This can result in increased brand visibility, authority, and organic traffic.


  • Enhanced Understanding of Content: Structured data and schema markup help search engines better understand the content and context of your web pages. By providing explicit information about entities, events, products, and other elements, you enable search engines to interpret and index your content more accurately. This can lead to improved relevance in search results and better visibility for specific queries.


  • Voice Search Optimisation: With the rise of voice search assistants like Siri, Google Assistant, and Alexa, structured data becomes even more valuable. By structuring your data with schema markup, you increase the chances of your content being featured in voice search results. Voice assistants rely on structured data to provide concise and accurate answers to user queries, making it crucial for voice search optimisation.


  • To incorporate structured data and schema markup into your website, you can use schema.org, a collaborative effort by major search engines to provide a standardised vocabulary for structured data. Schema.org offers a wide range of schemas to choose from, catering to different types of content, such as articles, products, events, local businesses, and more.


Implementing structured data and schema markup may require technical expertise or the assistance of a developer, but the benefits they bring to your website’s visibility, click-through rates, and relevance in search results make it a worthwhile investment in your Technical SEO strategy.

The Importance of Technical SEO

Optimising your website’s technical aspects is not a one-time task but an ongoing process. Regular SEO audits, monitoring page loading times, keeping up with mobile optimisation trends, ensuring website security, and leveraging structured data are all key practices for maintaining and improving your Technical SEO.

Remember, Technical SEO is not just about appeasing search engines; it’s about creating a seamless and enjoyable experience for your users. When your website is fast, secure, mobile-friendly, and easily navigable, it fosters trust, encourages engagement, and increases the likelihood of conversions.

As you continue to refine and optimise your website’s technical elements, be sure to stay informed about the latest trends and updates in the ever-changing world of SEO. By staying proactive and adapting to new advancements, you can stay ahead of the competition and continuously improve your website’s performance in search engine rankings.
