Ask most business owners what SEO means and they'll say "getting to the top of Google." That's the goal — but technical SEO is the foundation that makes it possible. Without it, content and backlinks are far less effective.
What Is Technical SEO?
Technical SEO refers to the behind-the-scenes aspects of your website that affect how search engines like Google crawl, render, and index your pages. It has nothing to do with what you write — it's about how your site is built.
Why Does It Matter?
Google can only rank pages it can find, render, and understand. If your site has crawl errors, broken links, duplicate content, slow load times, or missing structured data, Google will struggle — and your rankings will suffer, regardless of how good your content is.
The Key Technical SEO Components
Crawlability
Can Google's bot visit all your important pages? Your robots.txt file and XML sitemap tell Google where to go and what to skip. Misconfigured robots.txt can accidentally block your own pages from being indexed.
Page Speed and Core Web Vitals
Google uses page speed as a ranking factor. Slow sites rank lower and convert fewer visitors. Core Web Vitals optimisation — fixing LCP, CLS, and INP — is one of the fastest-impact technical SEO improvements you can make.
Structured Data (Schema Markup)
Schema markup is code added to your pages that tells Google what type of content you have — a business, an FAQ, a product, a review. Correct schema can earn rich results in Google (star ratings, FAQ dropdowns) which dramatically improve click-through rates.
Mobile Usability
Google indexes your mobile site first. If your site is hard to use on a phone — small text, overlapping elements, hard-to-tap buttons — it will rank lower regardless of your desktop experience.
HTTPS and Security
Sites without SSL (https://) are flagged as insecure by Google and browsers alike. This directly suppresses rankings and drives visitors away. Every site we build includes SSL as standard.
Internal Linking
How your pages link to each other tells Google which pages are important and how they relate. A well-structured internal link architecture distributes ranking power across your site and helps Google discover new content.
How to Know If Your Site Has Technical SEO Problems
Check Google Search Console — it's free and will flag crawl errors, mobile usability issues, and Core Web Vitals failures. Run your URL through PageSpeed Insights for a performance score. If either tool shows red or orange warnings, you have technical SEO issues to fix.
