Technical SEO Techniques for Boosting Website Performance

13 minutes read

A website serves as more than just an online presence; it’s the storefront to your virtual world. Just like a brick-and-mortar store requires an inviting entrance and direct navigation for visitors, a well-crafted home or landing page acts as a welcoming mat with seamless navigation that serves as the compass guiding visitors through your online offerings.

Understanding the language of search engines is fundamental in this digital realm. Your website speaks in HTML codes, using elements like content names, image file names, keywords, and titles. These components serve as beacons guiding search engines like Google to comprehend your content and rank it effectively.

However, the journey doesn’t stop with just website creation and code optimisation. To effectively navigate the digital space, businesses are adopting the ‘See, Think, Do, Care’ approach. That involves understanding your audience, delivering targeted content that resonates with their needs, and employing strategic analysis such as SWOT (Strengths, Weaknesses, Opportunities, Threats) to make informed decisions.

Crafting a clear mission statement and identifying your Unique Selling Points (USPs) further solidifies your direction in the digital realm. It’s about being seen, understood and valued by the right audience.

Central to this digital landscape is the role of search engines as matchmakers between websites and users seeking specific information. Marketing to showcase your USPs to the right audience at the right time becomes imperative. That involves strategic planning, including defining the target audience, selecting suitable platforms, allocating an advertising budget, and leveraging digital marketing channels.

At the heart of digital marketing lies the SEO (Search Engine optimisation) process to enhance a website’s visibility and performance on search engines. SEO aims to increase the quantity and quality of website traffic by optimising content to gain better visibility on search engine result pages (SERPs).

However, SEO is not a one-size-fits-all solution. Unethical practices like spam linking, keyword stuffing, or duplicate content are frowned upon and can negatively impact a website’s ranking.

Understanding user intent is significant. Searchers input keywords rather than complete questions, and it’s on SEO planners to attach relevant information to these keywords. Queries typically fall into three categories: navigational, transactional, and informational, each with distinct user intents.

Strategic placement of keywords across URLs, titles, meta descriptions, H1, content, and alt attributes is crucial for effective SEO. On-Page SEO focuses on optimising individual web pages, while Off-Page SEO involves obtaining referrals from authoritative websites and promoting across diverse digital channels.

Elements like image alt attributes, title tags, anchor tags, page speed, size, and responsiveness significantly impact a website’s SEO and SERP ranking. Creating informative and optimised elements enhances a site’s visibility in the competitive digital landscape.

When You Might Need a Sitemap:

A sitemap serves as a guiding map for search engines like Google, efficiently outlining the relationships between different pages and content on your website. While correctly linked pages can be discovered by Google, a sitemap becomes invaluable for larger or more intricate sites, enhancing the crawling process and improving overall visibility and accessibility.

<?xml version=”1.0″ encoding=”UTF-8″?>

<urlset xmlns=”″>








  <!– Add more URL entries as needed –>



Large Site Structure: If your website comprises numerous pages, navigating every page to ensure they are linked can be challenging. Large sites often face difficulties ensuring that all pages are interconnected. Consequently, Googlebot might not discover new pages promptly.

New Site with Limited External Links: Websites with few external links might struggle to be crawled by search engine bots. Googlebot primarily crawls the web by following links from one page to another. Without external linking, new pages may go unnoticed.

Rich Media Content or Inclusion in Google News: Websites containing extensive rich media content like videos, images, or those appearing in Google News can benefit from sitemaps. 

Sitemaps provide additional information that Google considers when indexing content for search.

Instances Where a Sitemap Might Not Be Necessary:

Smaller Sites: Websites with around 500 pages or fewer, where all crucial pages are well-connected and easily discoverable, may not require a sitemap. However, it needed to include pages that need to appear in search results within this count.

Comprehensive Internal Linking: Websites with a well-structured internal linking system, enabling search engines to navigate through all essential pages starting from the home page, might not necessarily need a sitemap.

Limited Rich Media or News Content: Websites lacking significant media files (videos, images) or news pages that don’t necessarily need visibility in search results might not need sitemaps. Sitemaps primarily assist in indexing such content for better visibility in search.

Understanding the Impact of .htaccess File on Website SEO

The .htaccess file, short for “hypertext access file,” influences a website’s search engine optimisation (SEO). Its proper configuration can yield substantial benefits, positively impacting various aspects of a website’s performance in the digital realm.

Optimising SEO with a Well-Written .htaccess File:

Enhanced Indexing and Crawling: A well-crafted .htaccess file can significantly improve a site’s indexability and crawlability by configuring directives that facilitate search engine bots’ access to web content. This ensures that search engines can efficiently crawl and index web pages, positively impacting visibility in search results.

Deconflicting Ranking Signals: By utilising directives within the .htaccess file, issues in ranking signals can be solved. That involves managing URL redirects, canonicalization, and handling duplicate content issues, ensuring search engines prioritise the correct pages for indexing and ranking.

Improved Page Load Speed: The .htaccess file allows for server-level configurations that optimise website performance. Implementing techniques such as browser caching, gzip compression, or defining expiry headers can significantly enhance page load speed, a crucial factor influencing SEO and user experience.

Directory-Specific Server Configurations: The versatility of the .htaccess file enables the setting of server configurations for specific directories within a website. Whether it’s the root directory, image folder (/images), or downloads directory (/downloads), custom configurations increase functionality and SEO within these areas.

Placement and Execution of .htaccess File:

The .htaccess file resides in a particular directory on the web server and is accomplished by the Apache web server upon a request from that specific directory. Placing the .htaccess file in the site’s root directory (e.g., /public_html) configures the entire website according to the directives defined within the file.

Considering Alternatives:

While the .htaccess file offers significant benefits, alternatives like the httpd.conf file for Apache provides a more centralised and efficient server configuration. Using the main server configuration file instead of numerous .htaccess files can reduce server load and streamline management.

It’s important to note that while the .htaccess file is a powerful tool, avoiding unnecessary proliferation across a server is beneficial. Consolidating configurations into the main server configuration file promotes good server management and performance optimisation.

Advantages of AMP for Different Stakeholder Groups

AMP (Accelerated Mobile Pages) benefits a broad spectrum of stakeholders: advertisers, publishers, and users, each experiencing distinct advantages:

Advertisers: AMP allows advertisers to leverage various advertising formats seamlessly. The asynchronous loading of advertising content ensures that user experience remains uninterrupted, enhancing engagement by preventing ads from delaying page loading.

Publishers: AMP ligranting their websites prominent placement in the news environment. Mobile-optimised AMP sites offer high usability, contributing to positive user signals and potentially increasing audience engagement.

Users: AMP-powered websites provide an optimal experience for users. The speedy loading of pages eliminates long wait times, ensuring a swift browsing experience even on slower internet connections. Users can trust consistent high performance, enhancing overall satisfaction while accessing content.

Implementing AMP in HTML: Key Changes and Tags

To implement Accelerated Mobile Pages (AMP) within HTML code, incorporate specific features and tags to ensure compliance with AMP standards and functionality. Here are the crucial changes and tags required:

Notable AMP Tags for Media Content:

Audiovisual media content like images, videos, audio, or iframes must contain notable AMP tags. Examples include amp-img, amp-video, amp-audio, or amp-iframe.

<amp-img src=”myimage.jpg” alt=”what you can see on the image” height=”200″ width=”300″></amp-img>

Mandatory Tags for Every AMP Page:

<!doctype html>: Specifies the document type.

<html> tag or <html amp>: The top-level tag indicating an AMP page.

<head> and <body> tags: Standard HTML structure elements.

Canonical Tag in Header: <link rel=”canonical” href=”” /> to define the canonical URL.

<meta charset=”utf-8″> in Header: Declares the character encoding.

<meta name=”viewport” content=”width=device-width, minimum-scale=1″>: Configures the viewport for responsive design.

Reference to AMP CDN: <script async src=””></script>: Links to the AMP Project JavaScript library.

Opacity Note: Sets opacity using CSS for handling elements when JavaScript is disabled.

Implementing these specific tags and changes within the HTML structure ensures adherence to AMP standards, enabling faster-loading, mobile-optimised web pages compliant with the AMP framework.

Controlling Web Crawling and Indexing: Leveraging Robots.txt and Meta Directives

Effectively managing search engine crawlers’ access to your website is vital for controlling which parts get indexed. Using robots.txt and meta directives like “robots” and “nofollow” allows webmasters to govern crawling and indexing behaviours, ensuring better control over how search engines interact with site content.

Robots.txt File:

In the site’s root directory, robots.txt instructs search engines for pages, files, folders, and subdomains to crawl or avoid.

Primarily prevents server overload by regulating requests.

Crawler directives guide the Googlebot’s navigation and can also direct it to your sitemap. 

User-agent: Googlebot 

Disallow: /Googlebot/ 

User-agent: * 

Allow: / 


Note: Don’t use a robots.txt file to hide your web pages from Google search results. 

If other pages point to your page with descriptive text, Google could still index the URL without visiting the page. If you want to block your page from search results, use another method like password protection or noindex. 

Crawler and Indexer Directives:

Crawler directives (robots.txt) specify where Googlebot can go and assist in pointing it to the sitemap.

Indexer directives control what Googlebot should index placed within HTML head elements for pages.

HTML Meta Directives for Indexing:

<meta name=”robots” content=”noindex”>: Prevents search engines from indexing a specific page.

<meta name=”robots” content=”nofollow”>: Instructs search engines not to follow links on a specific page.

<meta name=”robots” content=”noindex,nofollow”>: Combines both directives to prevent indexing and following links.

X-Robots-Tag Header for Specific Files:

Custom HTTP header control indexing for individual files or file types.


<FilesMatch “\.(docx|pdf)$”>

    Header set X-Robots-Tag “noindex, noarchive, nosnippet”


Nofollow Attribute for Links:

Adding rel=”nofollow” to a link instructs search engine bots not to follow the link and avoids passing link equity.

It’s important for untrusted content, sponsored links, user-generated content, or non-essential internal links.

Differentiating Between “noindex” and “nofollow”:

Use “noindex” to prevent indexing but allow following links, preserving link authority for linked pages.

Utilise “nofollow” when you wish to permit indexing and restrict following links important for pages with non-essential links.

Understanding the nuances between these directives helps the webmaster effectively manage the crawl budget, optimise search visibility, and ensure that search engines appropriately index and follow content based on site-specific goals and requirements.

Important: For the noindex rule to be effective, the page or resource must not be blocked by a robots.txt file and be otherwise accessible to the crawler. If the page gets blocked by the robots.txt file or the crawler can’t access the page, the crawler will never see the noindex rule.

Enhancing Multilingual SEO with Hreflang Tags

Hreflang tags, represented in HTML through the <link rel=”alternate” hreflang=”lang_code” href=”url_of_page” /> attribute, play a critical role in multilingual SEO, allowing search engines to understand and serve the appropriate language or regional version of a webpage to users based on their language preferences or location.

Implementation in the Head Element:

Each language or regional variation of a webpage should include <link> elements within the <head> section, denoting different language versions using hreflang attributes.

<link rel=”alternate” hreflang=”en-gb” href=”” />

<link rel=”alternate” hreflang=”en-us” href=”” />

<link rel=”alternate” hreflang=”en” href=”” />

<link rel=”alternate” hreflang=”de” href=”” />

<link rel=”alternate” hreflang=”x-default” href=”” />

Avoiding Duplicate Content Issues:

When offering similar content in multiple languages or regions, search engines might perceive them as duplicate content. Hreflang tags mitigate this issue by indicating the relationship between alternative versions, ensuring each version serves its intended audience.

Impact on Rankings and User Experience:

Hreflang tags influence rankings by signalling shared ranking signals within a hreflang cluster. The most relevant page within the cluster is displayed in search results based on user preferences or location.

Missing self-referencing hreflang tags can direct users to the wrong language version, resulting in a poor user experience, increased bounce rates, decreased time on site, and potentially affecting ROI.

Proper implementation of hreflang tags ensures search engines correctly identify and serve the most relevant language or regional version of a webpage, enhancing user experience and optimising visibility in international search results.

Optimising Website Performance: Strategies for Improved Page Speed Insights

Enhancing website performance involves a combination of technical strategies and best practices to improve page load times and overall user experience.

File Compression optimisation:

Consider using Brotli or Zopfli over Gzip for file compression, as these newer algorithms can further reduce file sizes and enhance load speed.

Server-Side Tagging and Script Management:

Implement server or cloud-side tagging solutions to manage and organise scripts, reducing the impact on page loading times.

Webpack optimisation Techniques:

Implement tree shaking and code splitting in Webpack to eliminate unused code (tree shaking) and separate code into smaller chunks (code splitting), facilitating faster loading times.

Preconnect and DNS Prefetch:

Warm up connections with <link rel=”pre-connect”> and <link rel=”dns-prefetch”> to establish connections to third-party domains in advance, accelerating resource delivery.

Immutable Caching Strategies:

Implement immutable caching techniques to cache static assets such as CSS and JavaScript files with long expiration times, reducing server requests and improving load speed for returning visitors.

File optimisation:

Compress CSS and JavaScript files using tools like CSSO for CSS and JS Uglify for JavaScript, minimising file sizes for faster downloads.

Font optimisation:

Utilise WOFF2 as the primary font format with WOFF as a fallback to ensure efficient font delivery while maintaining compatibility across different browsers.

Deferred Loading and Lazy Loading:

Implement deferred loading strategies for non-critical scripts and lazy load resources to prioritise initial page rendering.

Caching Mechanisms and Validation:

Use caching mechanisms efficiently and validate caching strategies to utilise cached resources optimally and appropriately updated when necessary.

Progressive Loading Approach:

Load initial inline markup promptly, then asynchronously load and cache additional resources in the background to improve perceived speed and user interaction.

Employing these strategies and continuously optimising website performance can significantly enhance page load times, reduce bounce rates, and improve overall user satisfaction, leading to a successful and engaging web presence.
