Technical SEO Services That Fix the Foundation Your Google Rankings Are Built On

• Crawlability — Google’s bots must be able to access every page you want ranked
• Renderability — Google must be able to render the full content of each page, including JavaScript-driven content
• Indexability — pages must be eligible for inclusion in Google’s index
• Speed — pages must load fast enough to meet Core Web Vitals thresholds
• Mobile usability — pages must perform correctly on mobile, where Google applies mobile-first indexing
• Structured data — machine-readable markup that helps Google understand page content and context
• Security — HTTPS implementation and no mixed content warnings
• Duplication management — clean canonical signals preventing content competing with itself

Technical SEO ensures all of these requirements are met — completely, consistently, across every page on your website.

Every technical SEO engagement begins with a comprehensive audit — a systematic crawl and analysis of your entire website that surfaces every technical issue affecting your Google rankings. Our technical audit covers all critical systems: crawlability, indexation, page speed, Core Web Vitals, mobile usability, structured data, redirect health, canonical implementation, and more.

The audit delivers a prioritised remediation plan — critical fixes first — with clear, developer-ready briefs for every technical issue that requires code changes. This connects to our full SEO audit service for businesses that want technical and on-page findings in one comprehensive report.

If Google cannot crawl your important pages efficiently, those pages will not rank. We audit and optimise your entire crawl architecture — ensuring robots.txt is correctly configured, XML sitemaps are complete and accurate, internal linking is structured to guide Google toward your most important pages, and crawl budget is not being wasted on low-value URLs like parameter variations, faceted navigation pages, or pagination.

For large websites, crawl budget management is a critical technical SEO discipline — one that has an outsized impact on how many important pages Google indexes and how frequently it recrawls them.

Not every page on your website should be indexed — and not every page you want indexed is being indexed. We audit your indexation status in full, using Google Search Console and crawl data — identifying pages that are incorrectly excluded from the index, pages that are incorrectly included, and the specific technical reasons behind every indexation anomaly.

Common indexation issues we resolve include noindex tags applied incorrectly, canonical tags pointing to wrong URLs, pages blocked by robots.txt that should be accessible, and soft 404 errors being served instead of real 200 status codes.

Google’s Core Web Vitals — Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) — are direct ranking signals. Websites that fail Core Web Vitals assessments rank below websites that pass them, all else being equal.

We audit your Core Web Vitals scores across every key page type — homepage, service pages, product pages, blog posts — and implement the specific fixes needed to move from failing to passing thresholds:

• LCP improvements — optimising the largest visible element’s load time through image optimisation, server response improvements, and resource prioritisation
• CLS fixes — eliminating layout shifts caused by images without dimensions, dynamically injected content, and web font loading
• INP optimisation — reducing interaction delays caused by heavy JavaScript execution and long tasks

Page speed affects rankings and conversion rates simultaneously. We conduct a comprehensive speed audit across mobile and desktop — using Google PageSpeed Insights, GTmetrix, and Lighthouse — and implement every available performance improvement:

• Image compression and next-generation format conversion (WebP, AVIF)
• Lazy loading of below-the-fold images and iframes
• Elimination of render-blocking JavaScript and CSS
• Browser caching implementation
• CDN setup and configuration
• Server response time improvement
• JavaScript and CSS minification and bundling
• Third-party script auditing and deferral
• Critical CSS inlining for above-the-fold content

Google indexes and ranks the mobile version of your website. If your mobile experience is slow, broken, or missing content that exists on desktop — your rankings suffer across all devices. We audit your mobile SEO performance in full — viewport configuration, responsive design issues, tap target sizes, font readability, mobile page speed, and mobile-specific content parity — and fix every issue that is creating a gap between your desktop and mobile performance.

Structured data gives Google precise, machine-readable information about your pages — enabling rich results in search that improve both visibility and click-through rates. We implement and validate the right schema types for your business:

• Organisation and LocalBusiness schema
• Article and BlogPosting schema
• Product and Offer schema for e-commerce
• FAQ schema for question-based content
• HowTo schema for instructional content
• Review and AggregateRating schema
• Service schema for service businesses
• BreadcrumbList schema for navigation clarity

Every schema implementation is tested using Google’s Rich Results Test and monitored through Search Console for errors.

Redirect chains, loops, and broken redirects waste crawl budget and dilute link equity. We audit every redirect across your website — identifying chains of three or more hops that need collapsing, redirect loops that prevent crawling, outdated 302 temporary redirects that should be 301 permanent, and broken links returning 404 errors that should redirect to live pages.

For websites undergoing or recovering from migrations, redirect auditing and management is one of the most critical technical SEO services we deliver.

Canonical tags tell Google which version of a URL is the authoritative one — preventing duplicate content from splitting ranking signals across multiple URLs. Incorrect or missing canonical tags are one of the most common technical SEO errors — and one of the most damaging on larger websites with many URL variations.

We audit every canonical tag across your website, fix incorrect implementations, and establish canonical governance processes that prevent new issues from entering production.

HTTPS is a ranking signal and a user trust signal. We audit your SSL implementation — certificate validity, mixed content warnings, HTTP to HTTPS redirect configuration, and HSTS header implementation — fixing every security issue that is affecting your rankings or sending trust-reducing warnings to visitors.

Modern websites — particularly those built on React, Vue, Angular, or other JavaScript frameworks — present specific technical SEO challenges. If Google cannot render your JavaScript-dependent content, those pages effectively do not exist in search. We audit your JavaScript rendering, test how Google sees your pages versus how a browser renders them, and implement the server-side rendering or prerendering solutions needed to make your JavaScript content fully visible to Google.

Websites serving multiple countries or languages need correct hreflang implementation to ensure Google serves the right language and regional version of pages to the right audience. Incorrect hreflang — the most common international SEO error — causes the wrong page versions to rank in the wrong markets. We audit, correct, and maintain hreflang implementation for every international website we manage.

E-commerce sites face specific technical challenges — faceted navigation creating thousands of thin URLs, product variant duplication, pagination issues, and large image libraries slowing page speeds. We resolve all of these as part of our eCommerce SEO service.

Large websites with thousands of pages require technical SEO governance at scale — crawl budget management, indexation monitoring, site architecture decisions that affect thousands of pages simultaneously, and processes that prevent technical debt from accumulating with every new site change. This is covered in our enterprise SEO service.

Franchise and multi-location websites need correct location page architecture, consistent NAP markup, and hreflang or geo-targeting implementation for multi-market websites. This connects to our franchise SEO and local SEO services.

Platform migrations and website redesigns are the leading cause of sudden ranking drops. We provide technical SEO oversight for every migration — pre-migration auditing, redirect mapping, post-launch crawl verification, and ranking recovery monitoring — so migrations improve your website without destroying your organic traffic.
