The custom improvements to our webshop were done professionally, in close cooperation with our technical partner and delivered within 2 weeks. We immediately noticed the results in our analytics: in the first month we measured a 14% conversion rate increase from organic search and +81% increase on paid search.

The core web vitals changed from 60 (fail) to +80 (pass) following the performance fix to one of our client's Magento webshop. Directly we saw the paid traffic conversions improve by almost 80%. Definitely due to the performance and also our Pmax optimizations.

The Performance Audit not only gave me practical insights to technical changes, but I also got important feedback how to improve the conversion rate in the buyer journey. Great value!

FAQ

Questions & Answers

Frequently asked questions and their answers

We take a custom development approach and don't rely on '3rd party plugin solutions' or quick-fixes. By addressing the core issues, back-to-front we can give long lasting performance guarantees and support to keep conversion results high!

You can and you should. However, it will take a lot more time and more than double the costs as performance optimisation is our niche expertise, not theirs. Even better: we'll be working closely together with them to get the job done.

Our performance sprint optimisation will guarantee you a Lighthouse performance score above 80 with all Web Vitals passed. Starting with the performance audit, we can fairly accurate predict your performance ROI based on conversion results.

We are specialised in Shopify, Magento and WooCommerce platforms, but in principle can support all Ecommerce platforms ranging from Shopware, BigCommerce to custom CMS platforms.

We work in close cooperation with your development team and require a staging environment to work with (an exact clone, but without customer data). After extensive testing, your team can deploy our optimisations, making it a risk free process. If your technical team is unavailable, we will support you in this as well.

The performance optimisation is done within a 2-week sprint, following the audit phase. Your marketing efforts will be impacted instantly the site speed improved.
