E-commerce optimisation: turn load time into conversions
Performance is critical: one extra second of load time means 7% fewer conversions. Here is how to make your e-commerce faster and grow revenue.
Fix Core Web Vitals, reach a score above 90 and lift conversions by 25-40%
E-commerce performance starts with Core Web Vitals. Through targeted optimisation I bring LCP under 2.5s, FID under 100ms and CLS under 0.1 on your site. Full site speed audit, targeted frontend and backend work, image optimisation and an advanced caching strategy. Even on complex stores with 10,000+ products, I find the bottlenecks slowing your page loads and tackle them in priority order to make your e-commerce faster.
- Complete e-commerce performance audit
- Core Web Vitals optimisation (LCP, FID, CLS)
- Frontend and backend load time improvements
- Technical SEO and global CDN distribution
Bring load time under 2 seconds and lift conversions by 30%
Load time is the number one factor behind conversions. Google confirms that 53% of mobile users leave if a page takes more than 3 seconds. With my optimisation work, I bring site speed under 2 seconds: intelligent lazy loading, prefetching of critical resources, Brotli/Gzip compression, font optimisation and a critical CSS path. Even with complex designs, I keep performance excellent, which feeds straight into conversions.
- Load time under 2 seconds, guaranteed
- Lazy loading to make your e-commerce faster
- Critical CSS for an optimised first paint
- Strategic prefetching and preloading
Lift mobile conversions by 30-45% with mobile-specific performance work
Mobile is 60-70% of e-commerce traffic but converts worse, largely because of poor load times. With mobile-first optimisation I improve performance on handsets: responsive WebP/AVIF images to cut page weight, optimised touch targets, simplified forms, one-page checkout. Even on slow 3G and 4G networks your store loads fast thanks to advanced service workers, lifting mobile conversions by 30-45%.
- Mobile-first e-commerce performance
- Responsive images for mobile site speed
- Service workers for offline loading
- Mobile checkout optimised for conversions
Strengthen technical SEO by 25% through Core Web Vitals and site speed
Since 2021 Google has used Core Web Vitals as a ranking factor for technical SEO. A store with excellent site speed ranks better, attracts more organic traffic and converts more. My optimisation work targets Core Web Vitals (LCP, FID, CLS) to earn the "good" badge in Search Console and strengthen technical SEO. Even in competitive categories, performance optimisation delivers a measurable 15-25% SEO boost in 2-3 months, increasing traffic and conversions.
- Core Web Vitals in the "good" band for technical SEO
- LCP under 2.5s for optimal load time
- FID under 100ms for a responsive experience
- CLS under 0.1 for visual stability

I have worked with Antonio for several years and he is, without a doubt, a professional in the truest sense of the word. Always available, highly skilled and extremely reliable, he is my go-to reference for anything in the Salesforce world.
Antonio was instrumental in migrating the Cisalfa Sport e-commerce to Salesforce Commerce Cloud. Thanks to his deep technical expertise and his ability to understand business needs, he led the project with method and vision, ensuring a smooth transition delivered on schedule. His contribution was decisive in coordinating the different stakeholders, resolving complex issues and maintaining high quality standards. A reliable, results-driven professional who brings real value to demanding projects.
I would like to express my appreciation for working with Antonio, who supported our Salesforce initiatives over the past months. Throughout our work together he consistently demonstrated professionalism and a strong commitment to delivering quality results. I wish him continued success in his future engagements.
Antonio worked on our restyling project and did an excellent job throughout the entire process. He was always extremely available, responsive and quick to understand every issue or requirement. His ability to frame problems quickly and propose effective solutions made the collaboration very efficient. He also showed great teamwork, working in perfect sync with the internal team while actively coordinating with the external agency. That kept the whole process smooth, clear and stress-free. Overall, his contribution was key to the success of the project and working with him was a very positive experience.
Antonio is one of the best developers I have worked with in my 10 years as a software developer. He can solve complex tasks independently, he is always ready to learn and to help at any moment, and he keeps the working environment very positive. He makes hard things look simple and he is an extremely motivated person.
Antonio provided me with Salesforce training. He was very knowledgeable and patient. He was always available to support me with any question or issue I ran into while using the application. It was a real pleasure working with him.
Antonio was key in translating technical needs into real business impact. He optimised our e-commerce performance, cutting bounce rate by 32% and lifting conversions by 28% in 3 months. He did not stop at the code: he mapped every intervention to the KPIs that matter to the board.
Even though our professional paths crossed only for a short time, in Antonio I found a skilled and dedicated professional, with a natural ability to work autonomously while keeping stakeholders constantly aligned.
Antonio was a very strong front-end developer on the project. He delivers clean, reliable UI work, follows the agreed designs faithfully and pays close attention to responsive behaviour and small details. Communication with him is easy and professional, and he is proactive in raising doubts early when something is unclear, which helps avoid unnecessary rework.
Frequently asked questions about e-commerce performance and optimisation
Everything you need to know about making your e-commerce faster, fixing Core Web Vitals and lifting conversions.
How do I know whether my store has a performance problem?
There are three clear signals of an e-commerce performance problem: a bounce rate above 50%, load times above 3 seconds, and mobile conversions markedly below desktop. If your pages load slowly, you are losing revenue every day.
Tools to check site speed: Google Lighthouse (the score should be above 80), PageSpeed Insights to examine Core Web Vitals, and Google Analytics to track average load time. If your Core Web Vitals sit below the "good" badge, you have a performance problem hitting both conversions and technical SEO.
