Technical SEO is the work of making a website easy for search engines to crawl, render, index and interpret. It covers site speed, mobile usability, crawlability, indexation control, structured data, internal linking, canonical tags and site architecture. It does not create demand on its own, but without it, content and link building deliver far less than they should. The usual way this problem presents itself: a business has invested in content, the writing is genuinely good, and nothing ranks. The cause is often not the content at all. It is that important pages are not being indexed, the site takes six seconds to load on a phone, half the pages are duplicated behind different URLs, or the internal linking gives Google no reason to think any page matters. ## What we check and fix ### Crawling and indexing Whether search engines can reach your pages and are choosing to index them. Robots directives, noindex tags left over from development, orphan pages with no internal links, and crawl budget wasted on pages that should not exist. ### Duplication and canonicals The same content reachable at several URLs splits its own ranking signals. We consolidate duplicates, set self-referencing canonicals, and make redirects, canonical tags and sitemap entries agree with one another rather than contradicting. ### Core Web Vitals and speed Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift, measured on real mobile conditions rather than a fast desktop connection. Usually the wins are image weight, render-blocking scripts, unused CSS and too many third-party tags. ### Mobile usability Tap target sizes, readable text without zooming, no horizontal scrolling, and no viewport settings that disable pinch zoom. The last one is both a ranking issue and an accessibility failure, and it is surprisingly common on themed sites. ### Site architecture and internal linking How pages relate to each other, how deep important pages sit, and whether your internal links tell search engines which pages matter. Breadcrumbs, hub pages and descriptive anchor text all do work here. ### Structured data Valid JSON-LD that accurately describes what is actually on the page. Generated from one central source so business details cannot drift apart across dozens of pages. ### Rendering Whether your content exists in the HTML or is assembled by JavaScript afterwards. Content that only appears after script execution is at the mercy of how thoroughly a crawler renders the page, and AI retrieval systems are frequently less patient than Google. ### Redirects and broken links Chains, loops, internal links pointing at redirects, and 404s that quietly lose both visitors and accumulated ranking value. ## Who needs technical SEO - Sites that have been rebuilt or migrated, where old URLs and redirects were handled loosely - Ecommerce stores, where filters and parameters generate enormous numbers of near-duplicate URLs - Sites built on heavy themes or page builders that ship far more code than the page uses - Businesses producing good content that is not ranking - Any site failing Core Web Vitals on mobile, which is most of them ## What you get A prioritised list rather than a data dump. Every finding is written as: what is wrong, what it costs you, how hard it is to fix, and whether it is worth fixing at all. Some technical issues are real but commercially irrelevant, and we will say so rather than billing to fix them. Where we have development access we implement the fixes ourselves. Where you have an in-house or third-party developer, we provide specifications precise enough for them to act on without needing to interpret. ## Cost and timeline Technical work is usually scoped as a defined project rather than an ongoing retainer, then followed by monitoring. Cost depends on site size, platform, and how much was left broken by previous work. A twenty page WordPress site is a modest project. A large store with a decade of accumulated URL problems is not. Effects appear faster than most SEO work. Once pages are recrawled, indexing and speed improvements can register within weeks. That makes technical work a sensible first step when you need to demonstrate progress early. ## Frequently asked questions ### What is technical SEO? Technical SEO is the work of making a website easy for search engines to crawl, render, index and interpret. It covers site speed, mobile usability, indexation control, structured data, canonical tags, internal linking and site architecture. It does not create demand by itself, but without it your content and link building deliver far less than they should. ### How do I know if I have a technical SEO problem? The clearest signal is good content that never ranks. Other indicators are pages missing from Google's index, a sharp drop in traffic after a redesign, slow mobile loading, or Search Console reporting coverage errors. An audit will confirm whether the problem is technical or something else entirely. ### What are Core Web Vitals? They are Google's measures of page experience. Largest Contentful Paint should be under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1. They are measured on real mobile visits, which is why a site that feels fast on office broadband can still fail them. ### Will technical SEO alone increase my rankings? Sometimes, when a specific problem was actively holding the site back, such as important pages not being indexed. More often it removes a ceiling rather than lifting you through it. Technical work makes everything else you do more effective, which is why it usually comes first. ### Can you work with our existing developer? Yes, and it is often the most efficient arrangement. We provide specifications precise enough to be implemented without interpretation, then verify the work once deployed. Where you have no developer available, we can implement directly.
