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.

πŸ’‘ 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.

Good:90-100
Needs improvement:50-89
Poor:0-49

Core Web Vitals

These indicators (LCP, FID, CLS) measure real user experience in the field. They are essential for SEO and visitor satisfaction.

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
