Why Performance Matters

  • Conversion Rate

    Every 100ms of delay costs you conversions. Amazon found that just 100ms of additional load time resulted in a 1% drop in revenue. For Magento stores processing thousands of transactions, even small speed improvements translate into significant revenue gains.

  • SEO Rankings

    Google uses Core Web Vitals as ranking signals in its search algorithm. Faster sites rank higher in search results, driving more organic traffic to your store. Poor performance means your competitors are outranking you.

  • Bounce Rate

    53% of mobile users abandon sites that take longer than 3 seconds to load. Every second of delay increases bounce rates and reduces the number of customers who make it through your checkout process.

  • Customer Trust

    Fast, reliable stores build confidence and encourage repeat purchases. Customers associate site speed with professionalism and trustworthiness, making performance a critical factor in long-term customer retention.

What We Optimise

  • Core Web Vitals

    LCP, FID/INP, and CLS optimisation to meet Google's performance thresholds and improve your search rankings. We target the specific metrics that affect your visibility.

  • Database Performance

    Query optimisation, indexing strategy, and table maintenance to eliminate slow database operations that bottleneck your store's response times.

  • Full Page Cache

    Varnish configuration, cache warming, and hole-punching to ensure your pages are served instantly from cache rather than regenerated on every request.

  • Frontend Performance

    JS/CSS optimisation, image compression, and lazy loading to reduce page weight and deliver a fast, smooth browsing experience on every device.

  • Server Tuning

    PHP, MySQL, Redis, and Elasticsearch configuration tuned specifically for your Magento store's traffic patterns and workload.

  • Third-Party Audit

    Identifying slow extensions and external scripts that drag down your store's performance. We pinpoint exactly what's costing you speed and recommend alternatives.
