BACKEND OPTIMISATION

Is a Slow Website Costing You Patience, Conversions, and Trust?

Slow loading, delayed interaction, layout shifts, heavy pages, and inconsistent performance can make an otherwise good website frustrating to use. The visible symptom may be “the site feels slow”, but the underlying cause can sit anywhere from image delivery to JavaScript, server response, database queries, or third-party scripts.

Slow Page Loads

Visitors wait too long for important pages to become useful.

Poor Core Web Vitals

Loading, responsiveness or layout stability falls short in real use.

Heavy Frontend Assets

Images, scripts and third-party code add unnecessary weight.

Backend Bottlenecks

Slow server responses and queries delay page generation.

We measure the current experience, isolate the main bottlenecks, and prioritise changes that can make the website meaningfully faster and more stable.

  • Core Web Vitals improvement work

  • Clear before-and-after validation where measurable

What Clients Say About Working With Us

Having a reliable team looking after the website has been a huge relief. Whenever something needs fixing or updating, ThinkDone is quick to respond and gets it sorted without turning a small issue into a big one. Exactly the kind of support we were looking for.

James A.

CEO, logistics firm

Absolutely love how the new store turned out! It’s faster, easier to navigate, and looks great on both desktop and mobile. The best part is that managing products and orders on our end is just as straightforward.

Lucas B.

Marketing Head, e-commerce brand

Our old website honestly wasn’t doing us any favours. ThinkDone took our ideas, cleaned everything up, and turned them into a website that actually feels like our business. The whole process was straightforward, and the end result has been great.

Elena O.

Product Lead, SaaS startup

Our product worked, but something about the experience always felt a little off. ThinkDone helped us identify where users were getting stuck and made some really smart changes. The difference was obvious as soon as we started testing the new design.

Emma J.

CEO, services firm

We’d tried SEO before, but never really understood what we were paying for. ThinkDone actually explained what they were doing, fixed the issues on our website, and helped us start showing up for the searches that mattered. We’ve seen a noticeable difference in both rankings and enquiries.

FAQ

Frequently Asked Questions About Performance Optimisation Services UK

01 How quickly can website performance improve?

Some changes can show measurable improvements quickly, while deeper issues may require development, infrastructure, or architectural work. Timing depends on the causes and scope.

Cost depends on the website, technology, number of templates, depth of diagnosis, and amount of implementation required. We review the current setup before recommending scope.

No. Automated scores vary by tool, conditions, page, device, and third-party code. We focus on meaningful user experience and technically sensible improvements rather than guaranteeing a particular score.

Yes, where relevant. We can investigate LCP, INP, CLS, and related performance issues, then recommend changes based on the real causes and technical constraints.

Yes. Most performance work starts with the website you already have. We measure the current experience and identify the strongest improvement opportunities.

Some changes can be invisible, while others may involve trade-offs in scripts, media, components, or third-party tools. We explain important implications before implementation.

Ongoing monitoring can be included where useful so regressions and meaningful changes are easier to identify.

Better performance can reduce user friction and Core Web Vitals are part of the wider search experience, but no responsible provider can guarantee a specific conversion or ranking outcome from speed work alone.
