What is Technical SEO?

Technical SEO refers to the process of optimising the technical aspects of a website to improve its visibility and ranking in search engine results pages (SERPs).

It focuses on enhancing the website’s infrastructure and foundation to make it easier for search engines to crawl, understand, and index your content effectively.

In simple words, technical SEO is about making your website more accessible and understandable to search engines, which in turn helps improve your site’s visibility and performance in search results.

Technical SEO vs On-Page SEO vs Off-Page SEO

While technical SEO, on-page SEO, and off-Page SEO are all crucial components of a comprehensive SEO strategy, they focus on different aspects of website optimisation:

  1. Technical SEO: Deals with the backend structure and performance of your website, including site speed, mobile-friendliness, crawlability, and indexability.
  2. On-page SEO: Focuses on optimising individual web pages’ content and HTML source code, including title tags, meta descriptions, header tags, and internal linking.
  3. Off-Page SEO: Involves activities performed outside the boundaries of your website to improve its search engine rankings. This includes building backlinks, social media marketing, guest blogging, influencer outreach, and online reputation management.

Essential Technical SEO Basics and Best Practices

Let’s explore some of the key areas of technical SEO and best practices to implement:

  • Creating and submitting an XML sitemap
  • Optimising robots.txt file

Page speed is a crucial ranking factor and directly impacts user experience. To improve site speed:

  • Optimise images and use appropriate formats
  • Minify CSS, JavaScript, and HTML

With the increasing prevalence of mobile devices, having a mobile-friendly website is essential. Best practices include:

  • Implementing responsive design
  • Optimising for mobile-first indexing

4. HTTPS Implementation

Secure websites are favoured by both users and search engines. Implementing HTTPS:

  • Builds trust with users

  • Provides a ranking boost in search results

5. Structured Data and Schema Markup

Implementing structured data helps search engines understand your content better and can lead to rich snippets in search results. Best practices include:

  • Using vocabulary
  • Implementing JSON-LD format
  • Testing structured data using Google’s Rich Results Test

6. Core Web Vitals Optimisation

Core Web Vitals are a set of metrics that measure user experience on web pages. Key areas to focus on include:

  • Largest Contentful Paint (LCP)
  • First Input Delay (FID)
  • Cumulative Layout Shift (CLS)

7. XML Sitemaps

XML sitemaps help search engines discover and understand the structure of your website. Best practices include:

  • Creating comprehensive XML sitemaps
  • Submitting sitemaps to search engines
  • Regularly updating sitemaps as your site changes

8. Internal Linking Structure

A well-organised internal linking structure helps both users and search engines navigate your site effectively. Best practices include:

  • Creating a logical site hierarchy
  • Using descriptive anchor text
  • Implementing breadcrumb navigation

9. Handling Duplicate Content

Duplicate content can confuse search engines and dilute your site’s ranking power. To address this:

  • Use canonical tags to indicate preferred versions of pages
  • Implement proper URL parameters
  • Avoid publishing similar content across multiple pages

10. International SEO Considerations

For websites targeting multiple countries or languages, international SEO is crucial. Best practices include:

  • Implementing hreflang tags
  • Using country-specific domains or subdomains
  • Creating localised content for different markets
