Frequently asked questions

Web performance (or WPO) is the art of providing fast display and good fluidity of web pages in browsers. During their loading and throughout their use, the pages of the website must load following a set of precise best practices. For a complete definition, check out the web performance definition.

Web performance is a new and complex field in web development. Profiles of web performance consultants are rare in the market and possess a comprehensive skill set in communication, UX, front-end and back-end development to best integrate into your technical teams.

Your teams certainly do not have the time to conduct web performance audits of your site or to test the speed of its pages. That’s why it is beneficial to delegate this essential part of your site's conversion (which contributes to SEO ranking) to a web performance agency or an expert in the field.

Web performance speaks to both the bots and the users of your site. Google has been encouraging good performance since 2021 with its Core Web Vitals Update. From a user perspective, a fast site is one that exudes quality and can reflect the quality of your brand. Some case studies, like those from Amazon, correlate loading time with the conversion rate of their online store.

Originally a full-stack developer, I am capable of optimizing both front-end and back-end performance. My advantage over other performance web agencies is my mastery of tools like Dynatrace or Datadog for identifying code optimization opportunities on the server side. On the client side, I work with all types of front-end stacks (React, VueJS, Astro, HTML / CSS / JS, ...) and mobile.

Multiple tools allow you to see the performance of the website. On Google PageSpeed, a bot is sent to your site, which will return a score out of 100 points. Other tools like Dareboost or GT Metrix also provide synthetic testing.

Depending on your needs, the size of your technical team, or the availability of your agency, I can offer you tailored support that matches your requirements and is suited to your business. The audit generally starts at €1500 excluding tax.
