SEO Performance and Core Web Vitals
Analyze and optimize Google PageSpeed key indicators
Why is loading speed crucial?
Google's algorithm and its evolution
Since the introduction of Core Web Vitals, Google has placed loading speed at the heart of its SEO ranking criteria.
💡 In practice:
A fast site improves both SEO and user experience, increasing conversions.
TTI: Key data for developers
Time to Interactive (TTI) measures the time needed for a page to become fully usable. It's a crucial indicator for evaluating JavaScript code efficiency and optimizing critical scripts.
By optimizing TTI, developers reduce blocking and improve user interaction fluidity.
Sustainable web eco-design
Digital performance and sustainability are inseparable. A high-performing website is an eco-responsible website. It consumes less energy, reduces its carbon footprint and offers optimal user experience.

How to analyze key indicators of a Google PageSpeed SEO audit?
The PageSpeed score
It's a global score (out of 100) that evaluates your site's performance. A high score is a good indicator, but it doesn't tell the whole story.
Core Web Vitals
These indicators (LCP, FID, CLS) measure real user experience in the field. They are essential for SEO and visitor satisfaction.

Why does Next.js make a website lighter than WordPress, Webflow, Drupal and others?
Fundamental optimization
Next.js enables architectural-level optimization (static rendering, streaming, etc.) that no plugin can match
Page weight control
You can precisely control every loaded resource, without code surplus
Energy efficiency
Less server-side computation, less data transferred = less energy consumed throughout the chain
Intelligent loading
Implement strategies like lazy loading, code splitting and critical resource prioritization
Native mobile performance
A mobile-first approach from design rather than an after-the-fact adaptation
