A site that meets Google's requirements
Creating a high-performing website is not just about making it fast. We design each project aiming for excellence in the 4 areas measured by Lighthouse, Google's reference tool. A solid foundation, right from the launch.
Performance
01Every site we create is designed mobile-first and optimized to achieve exemplary Core Web Vitals scores right from its launch. Controlled LCP for ultra-fast loading, zero CLS for a stable page, optimized INP for immediate responsiveness: your visitors benefit from a fluid experience, and Google remembers it in its rankings.
Accessibility
02Accessibility is integrated from the design stage, not added at the end of the project. Calculated contrasts, readable typography, keyboard navigation, rigorous semantic markup: your site respects WCAG standards and addresses all your users without exception. A commitment that broadens your audience and enhances the perceived quality of your brand.
SEO
03A well-built site is one that Google can read, understand, and value. Hierarchical HTML structure, clean meta tags, structured data, reduced DOM: we lay the technical foundations that allow your content to be crawled effectively and your pages to rank durably in search results.
Best practices
04Systematic HTTPS, optimized images, absence of vulnerable libraries, clean and maintainable code: each delivered site adheres to the most demanding web quality standards, attested in particular by our Opquast certification. You start with a healthy, sustainable site, designed to continue evolving over time.
What is GeneratePerf?
GeneratePerf is a Premium WordPress plugin developed and regularly updated by us since 2020. Used as a framework within our services, it ensures you benefit from the best of our expertise within the WordPress environment. It is also offered to everyone under an annual license on generateperf.com, with its complete documentation.
Included features
GeneratePerf, which unlocks its full potential when paired with the GeneratePress theme, comes with a dedicated dashboard that allows you to activate multiple built-in features with a single click.
These features advantageously replace popular plugins that generally create a bottleneck. Here is a detailed but not exhaustive list of supported features:
- Read count system compatible with cache plugins and activatable by post type

- Author boxes with or without links to author pages, and author listing shortcode (for "our team" page)
- Shortcode to display the list of authors on an "Editorial Team" type page
- Display of reading time and a lightweight scroll progress bar
- In-text and out-of-text related articles based on tags and categories
- Lightweight and functional contact form shortcode with the ability to activate an anti-bot system in 2 clicks

- One-click complete deactivation of comment support
- AI toolbar on articles: the reader summarizes, deepens, checks, or translates the page with one click in ChatGPT, Claude, Perplexity, Grok, or Google AI
Web performance optimization
GeneratePerf also allows you to benefit from advanced optimizations specifically designed to improve certain Core Web Vitals such as Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).
- Access to 97 self-hosted fonts optimized for performance, including 90 variable fonts: optimal subsetting, automatic preloads, fallback fonts calibrated against CLS…

- 2-click activation for GDPR compliance via an ultra-lightweight basic CMP. All advertising and tracking scripts are then loaded after consent and in an optimized manner.
- Automatic LCP optimization on featured images in articles and pages.
- Inline loading of SVG logo to improve loading times.

You have a question?
We have the answer!
Consult the FAQ for more details on the service.
Yes. We offer WordPress integration that regularly accompanies website creations.
We use the tools presented earlier, namely Gutenberg and GenerateBlocks, for a result that closely matches the mock-up design and top performance.
Yes, we can apply the methodology presented above to an existing site, with similar results in terms of performance and SEO.
Yes. We create complete WooCommerce stores : product catalog, payment, shipping, and associated extensions. A store requires specific work on category and product pages, and on a purchase process that is partly outside the cache : it is quoted separately.
Yes. We support all types of projects, including those that require advanced development : custom WordPress extensions, business logic, integration with your tools or connected user spaces (client account, member area, reserved content). These features are designed with the same performance requirements as the rest of the site, including on custom pages that bypass the cache.
The creation of a high-performance WordPress site starts from €2,000 excluding tax and progresses according to two variables: the extent of the graphic work, from adapting an existing brand guide to complete design, and the number of page templates to design.
The number of templates then weighs more than the number of pages. Fifty pages built on three templates cost less than ten completely different pages: it is the diversity of layouts that creates the work, not the volume of content. An online store requires a separate quote.
We provide a quote after discussing your project, your available content, and your deadlines. Contact us by email or phone describing your needs: we will quickly get back to you with a detailed proposal, item by item.
Allow 1 to 6 months depending on the scope of the project, as with a redesign. A showcase site with about ten pages, with ready content and an approved mockup, is built in a few weeks. A site with multiple templates or specific functionalities will take longer within this timeframe.
The limiting factor is rarely technical. Mock-up validation and content provision are the two stages that most often lengthen projects. We work in milestones so that each party knows at all times what is expected and by when.
WordPress brings three things that custom development must rebuild: an administration interface your teams already know, a proven ecosystem of extensions, and maintenance provided by a global community. The five-year cost of ownership is incomparable, for equivalent functional scope.
The performance argument does not favor custom-built solutions, contrary to popular belief. A well-built WordPress, on a simple theme and suitable hosting, achieves the same Core Web Vitals as an application developed for the occasion. Implementation is what matters, never the CMS.
Custom solutions remain relevant in specific cases : very specific business logic, exceptional data volume, deep integration with an existing information system. Outside of these situations, WordPress is the rational choice, and it is the one we recommend for the vast majority of projects. When yours falls into these categories, we also handle that development.
A new site creation starts from a blank page: no existing URLs to keep, no content to transfer, no SEO history to preserve. A site redesign rebuilds on an existing foundation, which adds two tasks: content migration and the redirection plan.
The choice criterion is simple. If the current site has an audience and established rankings, it's a redesign, and preserving SEO becomes a deliverable in its own right. If there is nothing to preserve, creation is faster and less expensive, as it bypasses these two stages.
