Your page speed and loading time performance work is led by experienced developers and SEO specialists, not juniors or automated tools.
Senior-led performance optimisation delivered by experienced website developers and SEO specialists, with clear ownership from diagnosis through to validation.
Real speed improvements, not chasing vanity scores.

A slow website costs you rankings, customers and revenue. Visitors abandon pages that take too long to load, conversion rates drop and search engines struggle to crawl and understand your site efficiently. Page speed is not just a technical concern. It is a commercial one.
We approach page speed optimisation as a technical performance project, not a score-chasing exercise. Our Birmingham-based senior web developers and SEO specialists work together to diagnose the real causes of slow load times, from inefficient code and plugin bloat to render-blocking scripts, oversized assets and CMS limitations, particularly on WordPress sites where theme and plugin decisions have a major impact on performance.
The goal is not to chase perfect scores or apply generic fixes. It is to make your site faster, more stable and easier to use within the real constraints of your platform. Where quick wins exist, we implement them. Where deeper structural changes are required, we explain the trade-offs clearly so you can make an informed decision.
Performance tools surface hundreds of recommendations but many have little impact on user experience, SEO or conversions. We start by understanding what is actually slowing your site down and which fixes are worth implementing.
Our approach is led by senior developers and SEO specialists working together. We prioritise changes that improve real-world performance, avoid unnecessary work, and stay honest about technical limits imposed by themes, page builders and third-party systems, especially within WordPress environments where flexibility and performance often pull in opposite directions.
We analyse real user data, code structure and page behaviour to identify the true causes of slow load times, not just tool-generated warnings.
We apply targeted fixes to code, scripts and assets where they make a measurable difference, and avoid work that won’t improve user experience, SEO or conversions.
We verify changes using performance data, Core Web Vitals (CWV) and real page behaviour to confirm that improvements are meaningful and stable.
“When we decided to redo our website, we called quite a number of web designers and were provided with numerous addresses of sites created by each designer. We found that ALT Agency had the most sites that we thought were innovative, creative and professional. After speaking a few times with ALT Agency we decided to go with them. It’s the best decision we’ve made in quite some time.
Joe Sapak“There are two important considerations when looking for a designer, work quality and reliability. Alt Agency offer both in spades.
Ben Stephenson“Craig is 100% on it and I mean on it, I can’t recommend him and ALT Agency highly enough.
Al Gosling“I found Craig & ALT Agency through the UKBF forums and I can honestly say its been a pleasure to work with Craig & his team. The end result is exactly what I wanted and more. The site is for my landscaping company with the aim of drumming up more business around our local area as well as somewhere to showcase our previous work to potential clients.

We reduce unnecessary CSS and JavaScript where it has a real impact. This can include CSS and JS minification, deferring non-critical scripts, combining files where appropriate and removing scripts that are no longer required.
Images are often the biggest performance bottleneck. We optimise image sizes, apply compression, serve next generation formats where supported and implement lazy loading so offscreen media does not block initial page rendering.
We reduce render-blocking resources and use preloading where it improves perceived speed. If deeper refactoring is needed, we explain the effort required and expected impact.
On WordPress and other CMS platforms, we audit themes, page builders and plugins to identify bloat, duplication and conflicts. Where possible, we streamline or replace inefficient components.
Page speed optimisation delivers the most value when performance is actively holding your site back. That might be high bounce rates on key landing pages, poor mobile usability, slow time to first interaction or clear issues flagged in real-user performance data. In these cases, improving speed can directly support conversions, engagement and SEO.
It is also worth prioritising performance when you are working with a bloated theme, an overgrown plugin setup or a WordPress site that has evolved without technical oversight. These environments often accumulate inefficiencies that are fixable without a full rebuild, making optimisation a sensible and cost-effective step.
However, page speed work is not always the right next move. If your website already performs in line with competitors or if limitations are imposed by third-party systems, page builders or required functionality, further optimisation may deliver diminishing returns. In these cases, we will be upfront about what is realistically achievable and whether deeper structural changes are the only way to move performance meaningfully. The aim is to apply effort where it creates impact.
Page speed optimisation sits between website development and SEO and demands both technical judgement and careful execution. Our senior specialists deliver all performance work in-house, planning, testing and validating changes properly, without generic plugins, account managers or long term commitments, and with clear guidance on what is worth fixing and what is not.
Your page speed and loading time performance work is led by experienced developers and SEO specialists, not juniors or automated tools.
Website development, SEO and QA teams work together under one roof, so all fixes are implemented quickly and without any risk.
All changes are tested properly before launch to protect functionality, data and revenue, with staging environments and internal QA used as standard.

Optimise Your WebsiteWill page speed optimisation improve rankings on Google?
Page speed is a ranking factor (and documented as one by Google themselves) but it is rarely a deciding one on its own. Improving performance can support SEO by improving user experience, crawl efficiency and CWV scores, but it will not compensate for weak content, poor structure or lack of authority. We treat speed as a supporting factor that removes friction, not a shortcut to rankings.
Do you guarantee PageSpeed or Lighthouse scores?
No. Guaranteed scores usually mean chasing tool metrics rather than improving real performance. We focus on changes that materially improve load time, stability and usability for real users. Where improvements are constrained by platform or required functionality, we are upfront about what is achievable before work begins.
What’s considered good page speed performance?
There is no universal “good” score. Performance should be judged in context, including your platform, functionality and how your site compares to competitors. If your site loads quickly for users and performs in line with or better than others in your market, further optimisation may deliver diminishing returns.
How long does page speed optimisation take?
That depends on the size of the site, the platform and what is actually holding performance back. Some improvements can be implemented quickly, while deeper issues may require code refactoring or structural changes. After an initial review, we are clear about what can be done, how long our page speed optimisation services will take and what impact to expect.
Is page speed optimisation a one-off project or ongoing?
It is usually handled as a defined project. Once the main causes of poor performance are addressed, ongoing work is not always necessary. Some clients choose periodic reviews, especially on sites that change frequently, but there is no long term commitment required.
Do you work with WordPress and custom platforms?
Yes. We are WordPress specialists and handle the majority of our performance work on WordPress sites. We have taken WordPress apart, rebuilt it and optimised it at code level while keeping it stable and update-safe. We also work with custom platforms and frameworks, where performance gains often require deeper technical changes rather than surface-level tweaks.
Can page speed optimisation break our website?
Poorly handled optimisation can, which is why we do not make changes blindly. All work is planned, tested and validated before it reaches your live site. We use staging environments and internal QA to ensure functionality, layouts and integrations remain intact.
How do you decide which performance fixes are worth doing?
We prioritise fixes based on impact, not volume. Changes are only made when they materially improve load time, usability or stability. If a recommendation is risky, platform-constrained or unlikely to deliver real benefit, we are upfront and leave it alone. That includes distinguishing between true hosting limitations and performance problems caused by code, assets or CMS configuration.
