Technical SEO.
Technical SEO services: crawlability, indexation, Core Web Vitals, structured data, and AI crawler optimisation. Senior technical SEO consultant with proven results.
Technical SEO services ensure your website is crawlable, indexable, and technically sound for both traditional search engines and AI answer engines. Unlike content-focused SEO, technical SEO addresses the infrastructure layer: site architecture, page speed, structured data, canonicalisation, and rendering. As a senior technical SEO consultant, I combine traditional technical SEO fundamentals with AI crawler optimisation so your site is ready for ChatGPT, Perplexity, Gemini, and Google AI Overviews.
Everything you need to
dominate search.
Crawlability and Indexation
If search engines cannot crawl your site, nothing else matters. I audit your robots.txt, XML sitemaps, canonical tags, and internal linking to ensure every important page is discoverable and indexable. For enterprise sites, I analyse server log files to see exactly how Googlebot, Bingbot, and AI crawlers interact with your architecture.
- robots.txt audit and optimisation
- XML sitemap generation and validation
- Canonical tag audit and conflict resolution
- Server log file analysis for crawl budget optimisation
- Orphan page identification and internal linking fixes
Core Web Vitals and Page Speed
Core Web Vitals are a confirmed ranking factor. I audit LCP, INP, and CLS across your site, identify the root causes of poor performance, and provide specific remediation guidance. For sites built on modern frameworks like Astro, Next.js, or Nuxt, I optimise rendering strategies and asset delivery.
- LCP (Largest Contentful Paint) optimisation
- INP (Interaction to Next Paint) debugging
- CLS (Cumulative Layout Shift) fixes
- Image optimisation and lazy loading
- JavaScript execution profiling and deferral
Structured Data and Schema Markup
Structured data makes your content machine-readable for both search engines and AI systems. I implement JSON-LD schema markup using Schema.org vocabulary, including Article, FAQPage, HowTo, Product, Organization, and BreadcrumbList schemas. Every implementation is validated against Google's Rich Results Test and Schema.org Validator.
- JSON-LD schema implementation (Article, FAQPage, HowTo, Product)
- Organization and Person schema for entity recognition
- Nested schema structures for AI visibility
- Rich results eligibility validation
- Schema error monitoring via Google Search Console
AI Crawler Optimisation
AI answer engines like ChatGPT, Perplexity, and Gemini retrieve content from the web using their own crawlers: GPTBot, PerplexityBot, and ClaudeBot. If your robots.txt blocks these crawlers, your content cannot be cited in AI-generated answers. I audit your AI crawler access and ensure your most important content is accessible to the systems that matter.
- AI crawler access audit (GPTBot, PerplexityBot, ClaudeBot, Google-Extended)
- robots.txt configuration for AI visibility
- Content accessibility testing for AI retrieval
- AI citation monitoring and tracking
- Integration with LLMO services for complete AI optimisation
Site Architecture and Internal Linking
Site architecture determines how efficiently search engines crawl your content and how link equity flows through your domain. I audit your URL structure, navigation hierarchy, internal linking patterns, and breadcrumb implementation to ensure your most important pages receive the most internal link equity.
- URL structure audit and recommendations
- Internal linking analysis and optimisation
- Breadcrumb implementation and validation
- Faceted navigation handling for ecommerce
- Pagination and canonicalisation strategy
Technical SEO Audits and Reporting
Every engagement starts with a complete technical audit. I crawl your site, analyse server logs, test Core Web Vitals, validate structured data, and benchmark against competitors. The result is a prioritised action plan with clear severity ratings and remediation guidance.
- Complete site crawl with Screaming Frog or custom crawlers
- Server log analysis for crawl budget insights
- Core Web Vitals field data from CrUX
- Competitor technical benchmarking
- Prioritised action plan with severity ratings
Common questions about Technical SEO.
What is technical SEO?
Technical SEO is the practice of optimising a website's infrastructure so search engines can crawl, index, and rank it effectively. It covers site speed, structured data, canonicalisation, robots.txt configuration, XML sitemaps, internal linking, and rendering. Technical SEO does not involve content creation or link building. It focuses on the technical foundation that makes those activities possible.
How much does technical SEO cost?
Technical SEO costs vary depending on site size and complexity. A freelance technical SEO consultant usually charges £1,000 to £5,000 for a complete audit. Ongoing technical SEO retainers range from £500 to £2,000 per month. Enterprise sites with 10,000+ pages or complex architectures may require custom pricing.
What is the difference between SEO and technical SEO?
SEO encompasses all activities that improve search visibility: content creation, link building, keyword research, and technical optimisation. Technical SEO is a subset of SEO that focuses specifically on the website's infrastructure. Content SEO focuses on what users see. Technical SEO focuses on what search engines see. Both are necessary for a complete SEO strategy.
How long does a technical SEO audit take?
A technical SEO audit usually takes 1 to 3 weeks depending on site size. Small sites (under 100 pages) can be audited in a few days. Enterprise sites (10,000+ pages) may take 2 to 4 weeks. The audit deliverable includes a prioritised action plan, severity ratings, and remediation guidance for every issue found.
Does technical SEO help with AI search?
Yes. Technical SEO is the foundation for AI visibility. AI answer engines retrieve content from the web using their own crawlers. If your site is not crawlable, not indexable, or blocks AI crawlers, your content cannot be cited in AI-generated answers. Structured data, fast page loads, and clear site architecture all contribute to how effectively AI systems can retrieve and use your content.
What AI crawlers should I allow?
The main AI crawlers to consider are GPTBot (ChatGPT), PerplexityBot (Perplexity), ClaudeBot (Claude), and Google-Extended (Google AI features). Allowing these crawlers gives your content the opportunity to be cited in AI-generated answers. Blocking them means your content will not appear in AI search results. The decision depends on your content protection strategy versus your AI visibility goals.
