Having a high-performing site at this very moment is good. Ensuring it stays that way over time is even better!

< Our web performance experts collect, analyze, and leverage your performance data />

Field approach

We continuously collect performance metrics from your real users by deploying a tag on your site (Request Metrics). This raw data, which includes Google's Core Web Vitals, is a key tool in identifying performance issues.

Continuous management

Our experts analyze the collected data, compare it, and interpret it weekly. They share a monitoring dashboard with you, containing their detailed observations, trends, and recommendations. This is a powerful tool to prevent any regressions.

Regular operational monitoring

Every quarter, we meet via video conference to present a summary of performance trends. This is a dedicated time to review recent deployments and jointly define priorities and key roadmap steps.

Premium Support

With over 308 clients supported since 2022, Agence Web Performance has developed an effective monitoring methodology, ideal for complementing a synthetic approach through Lighthouse or PageSpeed Insights tests. Contact us to discuss the best solution for you.

Reduce operational risks

Multiple factors can degrade a site's performance level without anyone noticing, or at least not soon enough.

Server maintenance

A server, regardless of its technical environment, requires regular updates. When these affect the web application (Apache, Nginx, LiteSpeed, php, MySQL, etc.), regressions or bugs can be introduced and impact the cache mechanism or overwrite custom configurations without displaying any alerts. A skipped algorithm or a reduced cache can cause TTFB to plummet.

Site update

Whether using WordPress, Prestashop, or any other framework, updates to the CMS, theme, or modules can introduce regressions: an explosion in the volume of loaded resources, introduction of Layout Shifts, etc. The logic is similar for custom developments, whether implemented by developers or generated by an AI like Claude Code.

Human contribution

We tend to consider that a majority of technical issues are the result of human error. This is true on the web, where deploying unoptimized content (especially images and videos) and integrating third-party JavaScript tools (tracking, analytics, A/B testing, etc.) can sometimes penalize an initially high-performing site. It is essential to see this to correct the course and train the teams.

High-value monitoring

There are many tools for monitoring web page performance: GTmetrix, WebPageTest, Pingdom, Calibre, DebugBear... Our approach, based on field data, or "Real User Monitoring" (RUM), is the most effective: it allows us to concretely identify issues with server response time (TTFB), perceived speed (LCP), visual stability (CLS), and interactivity (TBT and INP).

As a Contentsquare partner, we assist several major clients in using the CS Digital suite, and more specifically Find&Fix and its Speed Analysis module (formerly Dareboost). Similarly, as a professional Request Metrics user, we are able to help you make optimal use of it as part of our monitoring services.

We have the answer!

Consult the FAQ for details about the service.

What tools do you use to monitor pages?

Our monitoring relies complementarily on synthetic testing tools like Treo and Speed Analysis (based on Google Lighthouse) and Real User Monitoring tools like Contentsquare and Request Metrics.

However, we can rely on data from other tools such as DebugBear or Calibre (non-exhaustive list). They also collect performance metrics in the field and/or in the "lab".

What do you mean by "operational"?

As part of our monitoring services, an initial alignment and discovery phase allows us to get to know our clients: technical stack in frontend and backend, server infrastructure, team organization, roadmap functioning, production deployment schedule, etc.

This allows us to offer relevant solutions that are perfectly adapted to your constraints. The goal is to quickly and lastingly correct the detected issues!

How much does web performance monitoring cost?

The cost of the service mainly depends on the volume of pages to monitor. The idea is to be exhaustive in terms of page types covered: Home Page, Product Listing Page (PLP), Product Detail Page (PDP), Checkout... It is also advisable to monitor the most strategic pages for SEO and SEA (landing pages).
