Technical SEO Services Agency: Site Speed + Performance
Our technical SEO specialists audit and fix Core Web Vitals, crawlability, indexation, site architecture, schema markup, JavaScript rendering, and site migrations — building the technical foundation that allows your content and links to achieve maximum organic search rankings
01Full-Site Technical SEO Crawl
Running comprehensive site crawls using Screaming Frog, Ahrefs, and enterprise-level audit tools — identifying broken links, redirect chains, duplicate content, missing meta tags, orphan pages, thin content, incorrect canonical tags, and pagination errors across your entire site, with every issue categorised by severity and estimated ranking impact.
02Core Web Vitals Assessment
Measuring all three Core Web Vitals — LCP, INP, and CLS — across desktop and mobile using PageSpeed Insights, Chrome UX Report (CrUX), and lab data from Lighthouse — identifying the specific JavaScript, CSS, image, font, and server issues causing CWV failures with precise fix recommendations.
03Google Search Console Analysis
Deep analysis of your Google Search Console data — coverage errors, crawl stats, manual actions, security issues, mobile usability problems, Core Web Vitals field data, and search performance trends — integrating GSC intelligence with crawl findings to build a complete, evidence-based picture of your technical SEO health.
04Indexation and Crawl Budget Audit
Analysing how Google is crawling and indexing your site — identifying pages incorrectly excluded from the index, pages being crawled but not indexed, noindex misconfiguration, robots.txt blocking critical resources, crawl budget waste on low-value URLs, and XML sitemap issues — resolving every barrier to full and correct Google indexation.
05Structured Data and Schema Audit
Auditing existing schema markup for errors, missing properties, and opportunities — testing implementation against Schema.org specifications and Google’s Rich Result Test — then identifying additional schema types that would qualify your pages for rich results and knowledge panel features in Google Search.
06Prioritised Technical SEO Roadmap
Delivering a clear, implementation-ready technical SEO roadmap — issues ranked by estimated ranking impact, implementation effort, and urgency — with developer-ready specifications for every fix, acceptance criteria, and expected outcome, enabling your development team to implement improvements efficiently with complete confidence in priority ordering.
Technical SEO Audit Benefits
01Largest Contentful Paint (LCP) Optimisation
Optimising LCP — the time for the largest visible content element to load — through server response time improvement, LCP resource preloading, image format optimisation (WebP/AVIF), render-blocking resource elimination, lazy loading configuration, and CDN implementation — targeting sub-2.5 second LCP on both desktop and mobile devices.
02Interaction to Next Paint (INP) Improvement
Reducing INP — the responsiveness of a page to user interactions — through JavaScript execution optimisation, main thread blocking time reduction, long task elimination, event handler optimisation, and input delay reduction — achieving sub-200ms INP that signals excellent interactivity performance to Google’s page experience evaluation.
03Cumulative Layout Shift (CLS) Elimination
Fixing all sources of unexpected layout shift — adding explicit width and height attributes to images, iframes, and ads, pre-computing layout for dynamically injected content, stabilising fonts with font-display settings, and eliminating animations and transitions that shift content during load — targeting a CLS score below 0.1.
04Image Optimisation and Next-Gen Formats
Comprehensive image optimisation — converting images to WebP and AVIF formats for dramatically smaller file sizes, implementing responsive image srcsets, adding native lazy loading, optimising image dimensions to display size, and using image CDNs — often delivering 40-70% reduction in image payload that directly improves LCP and overall page weight.
05JavaScript and CSS Optimisation
Eliminating render-blocking JavaScript and CSS through code splitting, script deferral and async loading, unused JavaScript removal, CSS minification and critical CSS inlining, tree shaking, and third-party script audit — reducing Total Blocking Time (TBT), speeding first contentful paint, and improving the JavaScript execution efficiency that drives INP scores.
06Server, Hosting and CDN Optimisation
Improving server-level performance through server response time (TTFB) reduction, browser and server caching configuration, Gzip and Brotli compression, HTTP/2 and HTTP/3 protocol enablement, and CDN implementation with global edge nodes — ensuring fast, consistent site delivery to all users regardless of their geographic location.
Core Web Vitals and Speed Benefits
01Robots.txt Optimisation
Auditing and rewriting your robots.txt file to ensure it correctly guides Googlebot and other search engine crawlers — blocking crawl waste on low-value URL parameters, admin paths, and duplicate content while ensuring all high-value pages are explicitly crawlable, and verifying no critical pages or resources are accidentally blocked from crawlers.
02XML Sitemap Audit and Optimisation
Reviewing and rebuilding your XML sitemap structure — ensuring all canonical, indexable pages are included, removing noindexed and redirected URLs, implementing sitemap index files for large sites, setting accurate lastmod dates, submitting to Google Search Console, and configuring automatic sitemap generation on content publishing.
03Redirect Chain Resolution
Auditing your entire redirect architecture — identifying and collapsing multi-hop redirect chains into single direct 301 redirects, resolving redirect loops, updating internal links to point directly to final destination URLs, and implementing correct redirect status codes — eliminating the PageRank dilution and crawl efficiency problems caused by redirect chains.
04Canonical Tag Implementation and Audit
Auditing all canonical tag implementations across your site — identifying self-referencing canonicals, canonical chains, canonicalling to non-indexable pages, and pages missing canonical tags — implementing a correct canonical strategy that consolidates PageRank to preferred URL versions and prevents duplicate content from diluting ranking signals across variant URLs.
05Crawl Budget Optimisation
Analysing server log files to understand exactly how Googlebot is allocating crawl visits across your site — identifying URLs wasting crawl budget on low-value pages, parameters, and duplicate content, and implementing URL parameter handling in Search Console, noindex directives, and robots.txt exclusions that redirect crawl budget to your most important, revenue-driving content.
06JavaScript SEO and Rendering Optimisation
Auditing how Google renders your JavaScript-heavy pages — identifying content rendered client-side that Googlebot cannot effectively crawl and index, and implementing dynamic rendering, server-side rendering (SSR), or static site generation (SSG) solutions for affected pages — ensuring JavaScript frameworks like React, Vue, and Angular do not create invisible content for search engines.
Crawl and Indexation Benefits
01Organisation and Website Schema
Implementing Organisation, WebSite, and SiteLinksSearchBox schema — establishing your brand entity in Google’s Knowledge Graph, enabling sitelinks in branded search results, and providing search engines with authoritative information about your business including logo, contact details, social profiles, and founding information that appears in knowledge panels.
02Local Business Schema
Implementing LocalBusiness and specialised business-type schema — including business name, address, phone, hours, services, price range, and geo-coordinates — supporting your local SEO strategy and helping Google surface your business in local search results, map packs, and location-based voice search queries.
03Product and E-commerce Schema
Implementing Product schema with Offer, AggregateRating, Review, and Availability properties — enabling product-rich results in Google Shopping and organic search with star ratings, price, and stock status displayed directly in SERPs, dramatically increasing CTR for product pages and giving e-commerce organic listings a powerful visual advantage over schema-free competitors.
04FAQ and HowTo Schema
Implementing FAQ schema on service pages and HowTo schema on instructional content — enabling rich results that expand your SERP real estate with accordion-style questions and answers directly in search results, increasing visibility, establishing topical authority signals, and helping your content appear in Google AI Overviews and featured snippet responses.
05Article, Breadcrumb and Review Schema
Implementing Article schema with author, datePublished, and publisher properties that support Google’s E-E-A-T signals, BreadcrumbList schema enabling breadcrumb navigation in SERP listings, and Review/AggregateRating schema on service and product pages — collectively improving listing prominence, trust signals, and click-through performance in search results.
06Schema Validation and Rich Result Monitoring
Validating all structured data using Google’s Rich Results Test and Schema.org validator, monitoring rich result performance in Search Console’s Enhancements reports, fixing validation errors and warnings, and tracking CTR improvements from newly earned rich result features month over month.
Schema and Structured Data Benefits
01URL Structure and Hierarchy Design
Designing and implementing logical URL structures that clearly communicate content hierarchy to both search engines and users — using keyword-rich, descriptive URL slugs, consistent category path patterns, and clean URL formats without unnecessary parameters or subfolders — creating a URL architecture that signals relevance and supports topical authority signals.
02Internal Linking Strategy and Audit
Auditing your current internal link architecture — mapping PageRank flow, identifying pages with insufficient internal links (orphans), finding over-linked low-value pages, and analysing anchor text diversity — then rebuilding internal linking to strategically channel authority to your highest-priority commercial and ranking pages.
03Hub and Spoke Topic Cluster Architecture
Designing hub-and-spoke content architecture that groups related content into topical clusters — with comprehensive pillar pages linking to and from supporting cluster pages — signalling deep topical expertise to Google, improving content discoverability, increasing time-on-site through logical navigation, and strengthening rankings across entire keyword category areas.
04Faceted Navigation and Parameter Management
For e-commerce and large catalogue sites — auditing faceted navigation, URL parameter handling, and filter combinations that create thousands of duplicate and near-duplicate URLs — implementing canonical tags, robots.txt exclusions, parameter handling in Search Console, and JavaScript-based filtering that prevents crawl waste while preserving user experience.
05Breadcrumb Navigation Implementation
Implementing structured breadcrumb navigation across the site — with both visible HTML breadcrumbs and BreadcrumbList schema markup — improving user orientation, enabling breadcrumb display in Google search results, reducing bounce rates, strengthening internal linking hierarchies, and clarifying content relationships for Googlebot.
06Orphan Page Resolution and Content Integration
Identifying and resolving pages with no internal links pointing to them — the orphan pages that receive no PageRank and are often missed by Googlebot — by integrating them into relevant navigation, category pages, related content sections, and sitemaps, ensuring every valuable page on your site receives the internal link equity it needs to rank.
Site Architecture Benefits
01JavaScript SEO and Framework Optimisation
Auditing and fixing SEO issues in JavaScript-heavy websites built on React, Next.js, Vue, Angular, and Nuxt — identifying content rendered client-side that Googlebot cannot efficiently crawl, and recommending or implementing server-side rendering (SSR), static site generation (SSG), or dynamic rendering solutions that make all content visible to search engines.
02Website Migration SEO Management
Full SEO management for site migrations — domain changes, CMS migrations, HTTPS migrations, URL restructures, and site consolidations — including pre-migration crawl benchmarks, complete redirect mapping, post-migration validation, Google Search Console reconfiguration, and monitoring to ensure zero ranking or traffic loss through the migration process.
03International SEO and Hreflang Implementation
Implementing technically correct international SEO hreflang configurations for multi-language and multi-region websites — choosing between subdomain, subfolder, and ccTLD URL structures, implementing hreflang across all page variants, validating with testing tools, and monitoring international index coverage to ensure correct geographic search visibility.
04Log File Analysis and Crawl Intelligence
Analysing server access logs to understand precisely how Googlebot is crawling your site — tracking crawl frequency by URL, identifying pages Googlebot ignores, detecting crawl anomalies, measuring crawl depth distribution, and correlating crawl patterns with ranking changes — providing SEO intelligence impossible to obtain from standard audit tools alone.
05Enterprise Technical SEO Programs
Enterprise-scale technical SEO for large websites with thousands of pages — managing technical implementation across multiple CMS platforms, coordinating with multiple development teams, establishing SEO governance frameworks, and delivering ongoing technical health monitoring at the scale and complexity enterprise organisations require.
06AMP, PWA and Emerging Technical Standards
Advisory and implementation support for emerging technical web standards — Progressive Web App (PWA) SEO optimisation, Core Web Vitals improvement through modern web frameworks, Web Vitals monitoring integration, and alignment with Google’s evolving technical quality standards to future-proof your site’s technical SEO performance as ranking signals evolve.
