Histoire de vie réelle

Technical SEO is the behind-the-scenes work that ensures your website is properly structured for search engines. It’s the framework that supports all of your on-page and off-page efforts. Without a solid technical foundation, your content may never reach its full potential.

1. Site Speed as a Ranking Factor

Site speed, or how fast your pages load, is a direct ranking factor for both desktop and mobile search. Google’s algorithms favor pages that provide a fast, seamless user experience. A slow site has a higher bounce rate (users leaving quickly), which sends a negative signal to search engines.

2. What are Core Web Vitals?

Core Web Vitals are a set of three specific metrics that Google uses to measure a website's user experience. They focus on how fast a page loads, how quickly it becomes interactive, and how visually stable it is.

01

Largest Contentful Paint (LCP):

This measures how long it takes for the largest piece of content on the page (like a hero image or a block of text) to become visible. An LCP of 2.5 seconds or less is considered good.

02

First Input Delay (FID):

This measures the time from when a user first interacts with a page (e.g., clicks a button) to the time when the browser is able to respond to that interaction. A low FID score means your page is responsive.

(Note: FID is being replaced by Interaction to Next Paint (INP) in 2024, which measures all interactions, but the core concept remains the same: a fast-responding site is a good site.) An INP of 200 milliseconds or less is good.

03

Cumulative Layout Shift (CLS):

This measures how much unexpected layout shifts occur on a page. Think of a button moving down the page right as you're about to click it. A low CLS score indicates a stable and pleasant user experience. A CLS score of 0.1 or less is good.

3. How to Improve Your Core Web Vitals

You don't need to be a developer to understand the basics of improving your site speed. By focusing on these four key areas, you can make a huge impact:

Optimize Your Images:

Large images are the number one cause of slow websites. Use a tool to compress your images before uploading them, and consider using modern file formats like WebP. You can also implement "lazy loading," which only loads images as they appear on the screen.

Use a Fast Web Host:

Not all hosting providers are created equal. A slow, cheap host can limit your site's speed no matter what else you do. Investing in a quality hosting provider can make a significant difference.

Clean Up Your Code:

Your website's code (CSS, JavaScript) can slow it down. You can use plugins or services to "minify" this code, which removes unnecessary spaces and characters, making the files smaller and faster to load.

Enable Caching:

Caching saves a version of your website in a user's browser, so the next time they visit, the page loads almost instantly. This is a powerful way to improve return visitor speed and can be done easily with most content management systems (CMS) and plugins.
