Theme Speed &
Core Web Vitals
Read our 5 star reviews on Trustpilot
Theme code directly affects load speed and stability. Bloated CSS, render blocking JavaScript, inefficient template logic, and poorly managed assets all increase page weight and delay interaction. We refactor CSS, JavaScript, template files, and asset loading to reduce unnecessary requests, improve render paths, and raise Core Web Vitals scores. Core Web Vitals are Google’s performance measures for load speed, interactivity, and visual stability changes are measured before and after using performance tooling and GA4 behaviour signals. Work is delivered through the Development pathway on the StrategyFive Platform, within an agreed monthly time budget. The Performance Gateway and uplift guarantee do not apply.
What we optimise in the theme
CSS and JavaScript audit
Remove or defer scripts that block rendering and trim unused CSS.
Image delivery
Fix sizing, lazy loading, and responsive images so key pages load faster.
Fonts and icons
Reduce font overhead and load critical fonts more efficiently.
Interaction performance
Improve responsiveness by reducing heavy scripts and optimising event handling.
Third party control
Load third party tools only where they add value, and protect performance on mobile.
Performance guardrails
Add checks so future changes do not quietly undo the gains.

Seamless Migration and Outstanding Support!
We recently migrated our website to [strategyfive.io], and the experience was nothing short of exceptional. The migration process was incredibly quick and trouble-free, exceeding our expectations. What truly stood out was the amazing support we received throughout and following the migration. The team at [strategyfive.io] was (and are) always available, knowledgeable, and eager to assist with any questions or issues we had. Their dedication to customer satisfaction is evident, and we couldn't be happier with our decision to choose [strategyfive.io]. Highly recommended!

Personal service with excellent results!
The results on my website speed have been excellent, we had some teething problems at the start but they were dealt with super quickly. As an ecommerce business speed and up-time are so important and Eliot ensured that disruption would be minimal during the transfer. My Google Analytics data speak for itself with my bounce rate down significantly and the time people spend on my site greatly improved. A fast website is such a must in this day and age!

Helpful and prompt responses
Eliot has been really helpful hosting my website, I needed lots of things changing as my business was going in a different direction. He changed the pages I needed him too very quickly. Always there to answer questions. I get monthly updates for what is going on (I don't understand these but I'm sure he would explain if needed). In all he does what I expect - keep my website up and running.

Highly recommend [StrategyFive]
[StrategyFive] have been a breath of fresh air for us. The service is second-to-none. The speed improvement from our previous host is signifant. I'd highly recomment these guys to host your site if you're looking for a responsive, pro-active and professional service.
