Technical SEO
Technical SEO is the mechanical layer underneath every ranking factor — get it wrong, and nothing else you do for SEO fully works.
What technical SEO actually covers
Technical SEO is everything that determines whether search engines can efficiently crawl, understand and index your site, and whether your pages meet the performance and usability bar Google explicitly rewards. That includes site speed and Core Web Vitals, mobile usability, secure HTTPS, clean URL structure, correct canonicalisation (so Google doesn't treat near-duplicate pages as competing against each other), and structured data that explicitly tells search engines what your content is.
None of this is visible to a typical visitor, which is exactly why it's often neglected — but it's frequently the actual reason a well-written, genuinely useful page isn't ranking.
Structured data — speaking search engines' language directly
Structured data (schema.org markup) is a standardised way of explicitly telling search engines what a piece of content is — a service, a review, an FAQ, a local business — rather than making them infer it from unstructured text. It's also foundational to how AI-powered search and answer engines extract and quote information, which is why every page on the UNIT10 site carries appropriate structured data by default.
Site speed and Core Web Vitals
Google explicitly uses Core Web Vitals — loading speed, interactivity and visual stability — as a ranking factor, and speed independently affects conversion rate regardless of SEO. We diagnose real bottlenecks (unoptimised images, excessive JavaScript, poor hosting, render-blocking resources) rather than applying generic advice, and fix the ones that actually move the metrics for your specific site.
Frequently asked questions
What are Core Web Vitals?
Core Web Vitals are a set of specific metrics Google uses to measure real-world page experience: loading performance (Largest Contentful Paint), interactivity (Interaction to Next Paint) and visual stability (Cumulative Layout Shift). They're a confirmed ranking factor and a strong proxy for how a visitor actually experiences your site.
Why isn't my page ranking even though the content is good?
Good content is necessary but not sufficient. If the page is slow, not properly indexed, duplicated elsewhere on the site, or missing structured data, technical issues can prevent even excellent content from ranking as well as it should. A technical audit usually surfaces the actual cause.
Can you fix technical SEO on our existing site without a redesign?
In most cases, yes — technical SEO fixes are typically implementation work on the existing site (speed optimisation, structured data, sitemap and indexation fixes) rather than requiring a full rebuild, unless the underlying platform itself is fundamentally limiting.
