What Is Technical SEO?

Technical SEO is the behind-the-scenes work that lets search engines find, read and rank your site properly. You can have brilliant content and still get nowhere if Google struggles to crawl your pages, your site is slow, or something is quietly telling search engines not to index you.

It is the foundation everything else is built on. Get it wrong and the best content in the world will not save you. Get it right and every other bit of SEO work you do performs better. It is usually the first thing we look at when we take on a new site.

What We Fix

Crawling and Indexing

We make sure Google can reach every page that matters and is not wasting its budget on the ones that do not. Broken links, redirect chains, orphaned pages and rogue noindex tags all get found and fixed.

Speed and Core Web Vitals

Slow sites lose both rankings and customers. We improve load times, image sizes and the Core Web Vitals that Google uses to judge how good your site feels to use.

Structure and Schema

A clear site structure and the right schema markup help Google understand your pages and show you in richer results. We map it out properly and mark it up so nothing is left to guesswork.

How We Work

We always start with a full technical audit, so we are fixing real problems rather than guessing. Then we prioritise by impact, because a slow-loading homepage or a page blocked from indexing will hurt you far more than a minor warning buried in a report.

From there we work through crawlability and indexing, site speed and Core Web Vitals, mobile usability, structured data and internal linking, checking as we go so nothing breaks. You get a clear, plain-English rundown of what was wrong, what we changed and what it means for your visibility. No 200-page audit you will never read.

Technical SEO FAQs

What is the difference between technical and on-page SEO?

On-page SEO is about the content and keywords on a page. Technical SEO is about whether search engines can access and understand that page in the first place. You need both, but technical comes first.

Does my new site need technical SEO?

Often yes. New sites frequently launch with indexing issues, slow templates or missing structure. Getting the foundations right early saves a lot of pain later.

What are Core Web Vitals?

They are Google’s measures of how fast and stable your pages feel to a real user, covering loading speed, responsiveness and visual stability. Poor scores can hold your rankings back.

Will fixing technical issues actually improve my rankings?

On its own, technical SEO removes the things dragging you down. Combined with good content and links, it lets your whole site perform to its potential.
