Website Speed Optimisation for Faster, Smoother Pages
Find what is slowing your site down and fix it, from images and hosting to scripts and caching.
What Rocket provides
Rocket diagnoses and fixes slow websites. We measure how your pages load on real mobile connections, identify the heaviest causes and apply targeted fixes, so visitors see content quickly and interact without delay.
The free auditor below gives you a first read on your own site before you speak to us.
Speed is judged on mobile first, because most local visitors browse on phones, often on variable connections. A site that feels quick on office fibre can be painful on a mobile network.
Who it's for
- Sites that feel sluggish on mobile data
- Online shops where product pages take a long time to appear
- Companies running paid ads to slow landing pages
- Owners who have been told their site has poor Core Web Vitals
It also helps businesses that have recently added plugins, video or tracking tools and noticed the site getting heavier.
Problems it solves
- Visitors leaving before the page appears
- Oversized photographs that dominate page weight
- Plugins and tracking scripts that block the page from rendering
- Poor hosting or no caching
- Layouts that jump around while loading
Speed also affects advertising. If you pay for clicks that land on a slow page, part of that spend is lost before anyone sees your offer, so speed work and ad management often go together.
What's included
- Speed audit on mobile and desktop, with a plain-language report
- Image compression, correct sizing and modern formats
- Caching and, where suitable, a content delivery network
- Removing or deferring scripts and plugins that cost more than they give
- Font and CSS clean-up
- Database and server tuning on WordPress sites
- Re-testing to compare before and after
The report we provide lists each issue, its effect and what was done, so you can see exactly what changed.
Options
- Audit and report only, if you have a developer to apply fixes
- Audit and fix, where we do both
- Rebuild of slow templates when the theme itself is the problem
- Ongoing monitoring as part of website maintenance
If the site is on weak hosting, we will say so plainly. Upgrading the server can deliver more than any amount of tuning on an overloaded one.
What you'll need to supply
- Your website address
- Admin access if you want us to apply fixes
- Details of hosting, so we can see server limits
- A list of plugins or tools you consider essential
Please tell us about any recent changes, such as new plugins or a design update, since they often point straight to the cause.
How the process works
- Run the audit with the free tool or a deeper manual test.
- Rank the problems by effect and effort.
- Back up the site and work on a staging copy.
- Apply fixes in small steps and test after each.
- Check that forms, shops and tracking still work.
- Publish and re-test, then report the results.
What affects cost and timing
Cost depends on the number of templates, the state of the code, hosting limitations and how many third-party scripts are in use. Quick wins, such as images and caching, are inexpensive. Deep fixes to a poorly built theme can be a larger job.
We do not promise a specific score. Speed gains are measured and reported, but results depend on your content, hosting and design choices. Speed also affects search performance, which we cover in technical SEO.
Shops with many products, sites with video backgrounds and pages built with heavy page builders usually take longer to improve than simple brochure sites.

Frequently asked questions
Why is my website slow?
Common causes are large images, too many plugins, weak hosting and no caching. An audit shows which apply to you.
Is the free auditor enough?
It highlights major issues. A manual review goes deeper into templates, server and third-party scripts.
Will speeding up my site break it?
Risk is managed with backups and staging, and we test key functions before and after changes.
Does speed affect Google rankings?
Page experience is one of many signals. Faster pages also help visitors stay, but rankings cannot be promised.
How long does optimisation take?
Simple fixes can be done quickly. Larger jobs depend on the number of templates and the condition of the site.
