Is your website struggling to rank despite producing high-quality content? You might be facing underlying technical SEO issues. According to Search Engine Journal, 60% of websites contain technical errors that hinder performance.

Slow loading times, poor mobile compatibility, and indexing problems can prevent your site from attracting valuable organic traffic. A technical SEO company ensures your website meets search engine requirements by optimising crucial elements like speed, security, structured data implementation, and mobile responsiveness.

With Google’s Core Web Vitals now a critical ranking factor, investing in technical SEO is essential. This guide explores the key role of a technical SEO company and how it can dramatically improve your website’s search performance.

Understanding Technical SEO

What is Technical SEO?

Technical SEO focuses on the backend elements that influence how search engines crawl, index, and rank a website. Unlike content-focused SEO, which revolves around keywords and articles, technical SEO ensures a site is structured correctly, loads fast, and follows best practices.


Website Structure & Indexation

A well-structured website makes it easy for search engine bots to crawl and index pages efficiently.

Key Components of Website Structure:

  • XML Sitemap – Acts as a roadmap for search engines, helping them find and prioritize pages.
  • Robots.txt – Controls which pages search engines should crawl or ignore.
  • Canonical Tags – Prevent duplicate content issues by specifying the primary version of a page.
  • Orphan Pages – Pages with no internal links can be missed by search engines, reducing visibility.

How to Fix Indexation Issues:

  • Use Google Search Console to check for coverage errors and submit sitemaps.
  • Eliminate orphan pages by adding internal links to them.
  • Fix duplicate content with canonical tags or 301 redirects.

Core Web Vitals: Enhancing User Experience

Google’s Core Web Vitals measure three key performance factors that impact user experience:

MetricGood ThresholdNeeds ImprovementPoor ThresholdUser Experience Impact
Largest Contentful Paint (LCP)≤ 2.5s2.5 – 4s> 4sSlow loading frustrates users.
First Input Delay (FID)≤ 100ms100 – 300ms> 300msDelayed interactivity reduces engagement.
Cumulative Layout Shift (CLS)≤ 0.10.1 – 0.25> 0.25Unexpected shifts disrupt the experience.

How to Improve Core Web Vitals

  • Optimise Images – Use WebP format and compress large images.
  • Reduce JavaScript Execution – Minify code and limit third-party scripts.
  • Fix CLS Issues – Set explicit dimensions for images and avoid dynamic content shifts.

Security & HTTPS Implementation

Security is a Google ranking factor, and sites without HTTPS receive “Not Secure” warnings. A technical SEO company ensures:

  • SSL certificates encrypt user data.
  • HSTS (HTTP Strict Transport Security) forces HTTPS connections.
  • Canonical tags prevent ranking dilution from duplicate content.

Mobile Optimisation

With over 60% of searches on mobile, Google uses mobile-first indexing. A non-mobile-friendly website will struggle to rank well.

Key Mobile Optimisation Strategies:

  • Responsive Design – Ensure the layout adapts to different screen sizes.
  • Viewport Meta Tags – Ensure correct scaling for mobile users.
  • Touch-Friendly Elements – Buttons should be easy to tap.
  • Google’s Mobile-Friendly Test – Helps assess mobile usability.

Keyword Cannibalisation: A Hidden SEO Killer

Keyword cannibalisation occurs when multiple pages compete for the same keywords, confusing search engines and lowering rankings.

How to Fix Keyword Cannibalisation:

  • Conduct a keyword audit using Google Search Console.
  • Merge or redirect duplicate content to a single authoritative page.
  • Use internal linking to guide search engines to the most relevant page.

Schema Markup Implementation

Schema markup helps search engines understand your content. One of the most common types is FAQ Schema.
