SEO & Support Services Website Speed Optimisation
SEO & Support Services Website Speed Optimisation
Slow websites lose visitors before a single word is read. We audit, diagnose, and fix the performance issues holding your site back — from server response times to render-blocking scripts — delivering measurable improvements in Core Web Vitals and real-user load times.
What This Service Covers Performance engineering — not just plugin configuration
Most speed optimisation work stops at installing a caching plugin and compressing images. We go further: auditing the full request chain from DNS lookup to last byte, identifying the specific bottlenecks costing your site the most time, and fixing them at the root — whether that’s server configuration, unoptimised database queries, third-party script bloat, or inefficient asset delivery.
Core Web Vitals Optimisation — LCP, INP & CLS
Google’s Core Web Vitals are the primary performance ranking signals — and most sites fail at least one. We diagnose and fix each metric individually: LCP (Largest Contentful Paint) is addressed through image optimisation, preloading, and server response improvement; INP (Interaction to Next Paint) through JavaScript execution reduction and long task elimination; CLS (Cumulative Layout Shift) through explicit sizing, font loading strategy, and ad/embed stabilisation.
Fixes are verified against both lab data (PageSpeed Insights, Lighthouse) and field data (Chrome User Experience Report) — because a score that looks good in a test but performs badly for real users isn’t a fix.
Server Performance & Time to First Byte
TTFB (Time to First Byte) is where performance either starts well or starts badly. We audit your hosting environment, PHP configuration, database query performance, and object caching setup — identifying whether slow TTFB is caused by server resources, unoptimised queries, missing caching layers, or a hosting plan that’s simply undersized for your traffic.
For WordPress sites we configure object caching (Redis or Memcached), full-page caching with correct cache invalidation rules, and database query optimisation where slow queries are identified in the audit.
Image, Font & Asset Delivery Optimisation
Images are consistently the largest contributor to page weight on most websites. We audit your image pipeline and implement WebP/AVIF conversion, responsive srcset attributes, lazy loading below the fold, and preloading for above-the-fold images that contribute to LCP. Font loading is optimised with preconnect, font-display swap, and subsetting where appropriate.
JavaScript and CSS bundles are audited for unused code, code-split where applicable, and deferred or moved out of the critical rendering path to eliminate render-blocking delays.
CDN Configuration & Caching Strategy
Serving assets from a CDN edge node close to your visitor eliminates the latency of every request travelling back to your origin server. We configure CDN delivery (Cloudflare, Bunny CDN, or your existing provider) with correct cache headers, asset versioning, cache purge rules, and edge caching for full-page delivery where appropriate.
Caching strategy is designed holistically — CDN, full-page cache, object cache, and browser cache all working together rather than conflicting — with clear rules for what gets cached, for how long, and what triggers invalidation.
Why It Matters Speed is a ranking signal, a conversion factor, and a user expectation
A 1-second improvement in page load time increases eCommerce conversions by up to 7%. Google uses Core Web Vitals as a page experience ranking signal — sites that fail all three metrics are at a measurable disadvantage in competitive search results. And mobile users on average connections abandon pages that take more than 3 seconds to load, regardless of how good the content is.
Speed optimisation is not cosmetic. It directly affects how many visitors stay on your site, how many convert, and how well you rank for the keywords you’re targeting. Every second costs you money.
Tools & Platforms How we measure, diagnose, and verify performance improvements
WordPress performance is a specialism, not a side task
WordPress performance optimisation is not the same as general web performance work. Plugin conflicts, page builder overhead, WooCommerce query patterns, theme asset bloat, and the interaction between caching plugins and dynamic content all require WordPress-specific diagnosis and fixes. We’ve audited hundreds of WordPress sites and know exactly where the performance debt accumulates.
We also work on Next.js, Nuxt, and custom stacks — optimising server component boundaries, static generation strategy, image pipeline configuration, and bundle composition for modern JavaScript-heavy applications.
What’s included in a speed optimisation engagement
Every performance project starts with a full audit and ends with verified, documented improvements.
Full Performance Audit
A comprehensive audit covering Core Web Vitals field data, PageSpeed Insights lab scores, waterfall analysis, server response profiling, and a prioritised list of issues ranked by performance impact.
Core Web Vitals Fix
Targeted fixes for failing LCP, INP, or CLS metrics — diagnosed, implemented, and verified against both lab and field data with before/after reporting included.
WordPress Performance Package
Caching configuration, image pipeline optimisation, query profiling, plugin audit, and asset delivery improvements — delivered as a structured engagement with clear before/after metrics.
CDN Setup & Configuration
Cloudflare or Bunny CDN setup, cache rules, asset delivery configuration, and full-page caching where applicable — implemented correctly for your stack and CMS.
Technical SEO
Speed optimisation and technical SEO are closely related — Core Web Vitals directly affect search rankings. Our technical SEO service covers the full on-page and crawlability picture alongside performance.
Ongoing Performance Monitoring
Monthly Core Web Vitals and PageSpeed tracking, regression alerts, and a quarterly performance review included in our website support retainer plans.
Frequently asked questions
Common questions about website speed optimisation projects.
It depends on where you’re starting from and what’s causing the slowdown. Sites built on heavy page builders with no performance consideration often improve from 30–50 to 75–90 after a full optimisation engagement. Sites already at 70–80 can typically reach 90–95. We’ll give you a realistic target range after the initial audit — not a promise based on a number we haven’t measured yet.
No — the goal is to make your site load faster without changing its appearance or functionality. Optimisations are implemented and verified on a staging environment before being applied to production, and every change is tested against the live site’s design and interactive behaviour.
Yes, though page builder sites have a performance ceiling that’s lower than custom-built sites regardless of optimisation effort. We’ll tell you honestly what’s achievable with your current stack, and in some cases recommend a partial or full rebuild if the performance requirements can’t be met within the existing architecture.
A full audit takes 2–3 business days to produce. Implementation of recommended fixes typically takes 1–3 weeks depending on the number and complexity of issues identified. Some fixes (caching configuration, image compression) are fast; others (JavaScript refactoring, query optimisation) take more time but deliver proportionally more impact.
Yes. Google confirmed Core Web Vitals as a page experience ranking signal in 2021, and they remain part of the ranking algorithm. The impact is most visible in competitive niches where other ranking factors are roughly equal between competing pages — performance becomes the differentiator. Failing Core Web Vitals also affects your eligibility for certain rich result features in search.
