Our Technical SEO Services
Technical SEO Audit Service
Our technical SEO audit service in London uses in-depth crawls and a comprehensive, multi-point framework to uncover hidden backend issues, code errors, structural barriers and architectural flaws, delivered as clear, prioritised recommendations.
Site Architecture & Internal Linking
Restructuring URL hierarchies, flattening crawl depth, and strengthening internal linking so both users and bots reach your key pages in fewer clicks. Good architecture is the backbone of every other technical fix. Our on-page SEO services then tune the anchor text on every page.
Crawl Budget & Log File Analysis
Reviewing raw server logs to see exactly how search engine bots crawl your site, then cleaning up low-value pages and wasted requests so bots focus on your most important content. Most impactful for large or fast-changing sites. Our log file analysis guide shows the process step by step.
Indexation, Canonicals & Duplicate Content
Configuring robots.txt, XML sitemaps, meta robots and canonical tags so search engines index the right high-value pages, ignore the rest, and never split rankings across duplicate URLs. For ecommerce filters, see our faceted navigation SEO guide.
Core Web Vitals & Site Speed
Optimising LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift) through image compression, server response improvements, script optimisation, and caching for faster, more stable, more responsive pages.
JavaScript SEO & Rendering
Optimising dynamic, JS-heavy frameworks (React, Angular, Vue) so search engine bots can render and read your content properly, with no lost visibility. Learn more in our JavaScript SEO guide for React and Next.js.
Headless & API-Driven SEO
For headless CMS and API-driven builds, we ensure search engines can access structured content, configuring pre-rendering, dynamic rendering, and SSR or hydration strategies so your site ranks as effectively as a traditional build. Read our headless SEO guide for the details.
Schema Markup & Structured Data
Adding specialised JSON-LD code to help search engines and AI systems understand your content so the content could earn rich snippets and improve eligibility for AI Overviews and knowledge graph results. See schema markup explained, with JSON-LD examples.
International SEO & Hreflang
Setting up proper hreflang tags and URL structures as a technical SEO company for businesses targeting multiple countries, regions, or languages. Each market is built on international keyword research, so every regional page targets the terms local buyers actually use. Our hreflang tags guide covers the setup.
SEO-Safe Website Migrations
Safely moving a website to a new domain, host, CMS, or platform without losing hard-earned rankings, backlinks, or traffic with full redirect mapping and staged risk monitoring. That protects the authority your link building has already earned.
Mobile-First Optimisation
Auditing and maintaining responsive design, touch elements, and media rendering to keep pace with Google's mobile-first indexing standards.
AI Search Readiness (GEO)
Structuring your content, schema, and authority signals so AI-driven search such as ChatGPT, Gemini, Perplexity, and Google's AI Overviews can accurately read, understand, and cite your site. We configure llms.txt, semantic markup, and entity signals to help you surface in AI-generated answers. For full AI visibility campaigns, see our generative engine optimisation agency.

Frequently
Asked Questions
We’ve heard it all. Here’s everything you need to know before working with us.
Technical SEO optimises your site's backend architecture, code, and speed so search engines and increasingly AI systems can crawl, render, index, and understand your pages. Partnering with a specialist technical SEO agency ensures this happens without friction.
Standard (on-page) SEO focuses on content, keywords, and link building. Technical SEO concentrates on website infrastructure, crawlability, indexation, speed, mobile usability, and server configuration so that great content actually gets found.
We recommend a professional technical SEO audit at least once a year. If you frequently update your site, launch new products, or redesign pages, quarterly audits help spot underlying errors early, before they compound. For a quick self-check between audits, follow our 60-minute technical SEO audit guide.
Yes. Performance optimisation including image compression, code minification, and caching is core to our service, aimed at improving LCP, INP, and CLS alongside overall load times.
As part of our audit process, we review server logs, refine your robots.txt file, fix sitemaps, and correct canonical tags to direct search bots towards your key revenue-generating pages.
Yes. JavaScript frameworks like React, Angular, or Vue and headless/API-driven builds can hide content from search bots if not configured correctly. Our specialists optimise your rendering pipeline, including SSR and hydration strategies, so search engines read your content without issue.
Working with our team minimises risk. We handle complete redirect mapping, staging environment checks, and canonical updates so you retain search visibility when changing domains, hosts, or platforms. Our SEO website migration checklist shows every step we follow. For full platform, domain or ecommerce moves, our website migration services bring development and technical SEO into one plan.
Schema is structured code added to your pages. We implement it to help search engines and AI systems understand your content by qualifying your brand for rich snippets and improving your chances of appearing in AI Overviews and generative search results.
Yes. We structure your content, schema, and entity signals so AI crawlers and generative search tools can accurately read, understand, and cite your site. Our technical SEO consultancy helps you appear in AI-generated answers as well as traditional rankings.
Google prioritises mobile-first indexing. We audit responsive layouts, touch targets, and mobile speed to ensure your site performs flawlessly across every device.
Unlike long-term content strategies, technical fixes often deliver fast wins. Once we resolve crawl blocks or site speed issues, search engines can re-index and improve rankings within days or weeks.
Cost depends on the size and complexity of your site, from a small business website to a large ecommerce or international platform. We scope every engagement after a free audit call and confirm a fixed price before any work starts, so there are no surprises.
A full crawl and indexation review, Core Web Vitals and site speed analysis, JavaScript rendering checks, site architecture and internal linking, schema validation and a review of your Google Search Console data. You receive a prioritised fix list ranked by impact and effort, plus a walkthrough call with our team.
Both. You can book a one-off technical SEO audit, a fixed-scope project such as a migration or a Core Web Vitals clean-up, or an ongoing monthly retainer where we monitor, fix and report continuously.
Yes. We write developer-ready tickets with clear acceptance criteria, can join your sprint planning, and check every fix before it goes live. If you don't have developers, our own development team can implement the changes.
We work with WordPress, Shopify, WooCommerce, Magento (Adobe Commerce), Webflow, custom builds, and headless or JavaScript frameworks such as React and Next.js.
Designer Listings
Both. A senior technical SEO consultant leads your audit and strategy, backed by our wider team of technical SEO specialists and developers who can implement the fixes. Many clients use us as an outsourced technical SEO consultancy that works alongside their in-house team.
Yes. Our SEO audits for London businesses cover crawlability, indexation, Core Web Vitals, JavaScript rendering, schema and internal linking, and we can meet in person or run the whole audit remotely. Companies elsewhere in the UK get exactly the same technical SEO services online.
Yes. We regularly fix WordPress technical SEO issues such as slow themes and plugin bloat, thin tag and archive pages, sitemap and canonical settings, and Core Web Vitals, whether you use Yoast, Rank Math or a custom setup. Our web development team can make the changes for you.
