Web performance audit by web performance experts

Don't let a slow site nullify the potential of your online business!

< Our web performance experts audit your site to identify performance issues />

Focus on Core Web Vitals

Our audits are focused on Core Web Vitals to be as close as possible to Google's expectations. This allows us to prioritize fixes based on the weaknesses highlighted in Search Console in order to achieve concrete effects on field data (CrUX) quickly.

User and SEO Impact

Each issue detected is accompanied by detailed explanations of its concrete effects, both for visitors in terms of User Experience (UX) and for search engines and indexing robots (SEO-oriented approach).

Precise Operational Recommendations

Through the audit deliverable, we detail all the improvement points identified, explaining for each what the problem is, how it should be corrected, and the expected impact on web performance metrics. We share custom code (CSS, HTML, JavaScript, PHP, etc.) that can be implemented within your technical stack.

We audit all technical stacks

A service in 6 key steps

Our performance audits are broken down into several key stages.

Technical Alignment

We meet via video conference to discuss with your teams and discover your technical stack in detail. We review the issues identified, the steps already taken, and your web performance goals. This ensures a service that precisely meets your needs.

RUM Tag Implementation

We place a tag on your site that collects performance data from your real users. This "RUM" data is used to precisely identify bottlenecks. Thanks to this data-driven approach, we operate with maximum visibility on your issues.

Site Audit

Our web performance experts conduct a complete audit of your site. They consolidate the detected issues in a detailed deliverable and provide a list of operational recommendations. Our pragmatic and concrete approach guarantees the effectiveness of future fixes.

Prioritization of Recommendations

We rank our recommendations using the RICE prioritization method: Reach (number of users reached), Impact on performance, Confidence, and Effort of deployment. We thus design your web performance roadmap by prioritizing the rapid deployment of quick wins for measurable results.

Deliverable Presentation

We meet again via video conference to present the deliverable to your internal teams or your development agency. This is an essential exchange to ensure that the operational recommendations are understood and will be deployed optimally.

Testing of deployments

We check the effectiveness of the fixes once the developments are implemented in your pre-production environment or directly in production. A steering dashboard allows us to communicate continuously until the implementations are finalized, within a maximum of 6 months.

Why conduct a web performance audit?

Conducting a performance audit allows us to detect the concrete issues with your site, those that impact its page loading times, and therefore user experience and SEO visibility. It is also an opportunity to assess your site's compliance with web development best practices.

Our in-depth expertise is the best way to identify what needs to be modified by your front-end development teams. And therefore to correct it quickly and sustainably.

Should we prioritize an audit or optimization?

It depends on the maturity of your development teams. If the tools and stack are perfectly mastered, you can choose an audit rather than optimization by us. If this is not the case, we advise you to rely on our experience for us to carry out the identified modifications on your site ourselves.

What CMSs can you audit?

We audit all types of sites, regardless of their nature. This includes sites built on WordPress, Prestashop, Shopify, Magento, SalesForce Commerce Cloud, SAP Commerce Cloud (formerly Hybris), Drupal, etc. But also custom-built sites developed from scratch.

Can you audit an SPA in Angular or React?

Absolutely. We invite you to consult our page dedicated to Single Page Application (SPA) optimization. Modern frameworks like React, Angular, or Vue.js, while increasingly performant, present specific challenges in terms of web performance.

Specific focus is thus placed on client-side rendering, state management, and initial load optimization. Our analysis concentrates on these crucial aspects, using advanced tools and methodologies: this ensures optimal performance for your web application.

How much does a web performance audit cost?

The service is offered in the form of a fixed-price package. This package may optionally include prioritization and/or acceptance testing options. We can provide you with a quote upon simple request by email or phone.
