WordPress Speed

Optimisation UK

No. All optimisations are tested on a staging environment before being applied to your live site. We never make changes that break functionality — if a plugin is slowing your site and can't be safely optimised, we'll document it and present options rather than simply removing it.

Core Web Vitals is a confirmed Google ranking factor. Speed improvements can influence rankings within 2–4 weeks, though this varies depending on how frequently Google crawls your site. The PageSpeed improvement itself is instant — visible in Insights on the same day.

Sometimes. If your server response time (TTFB) is above 600ms, it's often a hosting issue that no amount of code optimisation can fully overcome. We'll flag this in the audit and can recommend faster hosting options — but optimisation is included regardless.

Plugin updates, new content or theme changes can re-introduce performance issues over time. We offer optional monthly monitoring as part of our WordPress Care Plans (from £150/month), which catches regressions before they affect your rankings.

These are the three Core Web Vitals metrics Google uses to assess page experience. LCP (Largest Contentful Paint) measures how quickly the main content loads — target under 2.5 seconds. INP (Interaction to Next Paint) measures how quickly your page responds to user input — target under 200 milliseconds. CLS (Cumulative Layout Shift) measures visual stability — target under 0.1. All three are confirmed Google ranking signals. We benchmark, fix and re-verify all three in every speed optimisation project.

WordPress speed optimisation is a one-off fixed-price service. Pricing depends on your current score, site complexity and hosting environment — typically between £400–£900 for most WordPress sites. A free performance audit call lets us benchmark your scores and quote accurately before you commit to anything. The audit is free regardless of whether you proceed.

The most common causes, in order of frequency: uncompressed images served at the wrong dimensions; render-blocking CSS and JavaScript; unused or bloated plugins; no caching layer (or badly configured caching); slow TTFB from underpowered shared hosting; missing lazy loading on below-the-fold images; Google Fonts loaded synchronously; and excessive third-party scripts (chat widgets, analytics, marketing pixels). Most sites have five or more of these issues simultaneously.

Yes. WooCommerce adds specific performance challenges: cart fragment refreshes on every page load, complex database queries for variable products and uncached checkout pages (which must stay uncached for GDPR compliance). We handle WooCommerce-specific optimisation including fragment caching configuration, database query tuning and product page image optimisation. WooCommerce speed work is included in our standard optimisation service.

Yes. We work on any WordPress site regardless of who built it. If the site was built with a page builder like Elementor or Divi, optimisation is harder — these generate excessive CSS and JavaScript that's difficult to remove without redesigning the pages. We'll tell you upfront what's achievable and quote accordingly. Sometimes a rebuild is more cost-effective than trying to optimise a site that's structurally slow.

TTFB — Time to First Byte — measures how long it takes your server to respond after a browser requests a page. A TTFB above 600ms is a server-side problem that affects all other speed metrics. The fix is usually better hosting, adding a caching layer (Redis or Memcached), or moving to a faster managed WordPress host. We measure TTFB as part of every speed audit and flag hosting issues where relevant — no charge to do so.

Yes. The optimisations we apply — image compression, caching, code minification, lazy loading, deferred scripts — are invisible to the end user. Your site will look identical before and after; it will simply load faster. We never redesign or modify your content as part of a speed optimisation project unless you specifically ask us to.

For most UK businesses, we recommend Kinsta, WP Engine or Cloudways — all managed WordPress hosts with built-in caching, CDN, staging environments and UK data centres. For high-traffic sites, Kinsta on a Business or Enterprise plan is the most reliably fast option we've tested. We don't take affiliate fees for recommending hosts — the recommendations are based purely on performance and reliability.

We provide before-and-after PageSpeed Insights scores, Core Web Vitals reports from Google Search Console and TTFB measurements from two locations. You can verify every metric independently using the same tools. We also monitor rankings and organic traffic in the weeks following optimisation so you can correlate the speed improvements with search performance changes.
