How to improve your Lighthouse score for a successful e-commerce site

The world of e-commerce is constantly evolving and to stay competitive, it is imperative to offer your users an exceptional experience.


1. Loading time

The loading time of your website can be a deciding factor for customers. Here are some tips to improve your loading time:

Image optimization

Use formats like WebP to reduce the size of your images without losing quality.

 <img src="produit.jpg" alt="Photo du produit">

 <img src="produit.webp" alt="Photo du produit">

Using Lazy Loading

Lazy loading of images can also improve performance.

 <img src="produit.webp" alt="Photo du produit" loading="lazy">

2. SEO

Good SEO is essential for your site to appear in search results.

Meta tags

Meta tags like title and description are essential.

<title>My e-commerce site</title>
 <meta name="description" content="Buy the best products online">

URL structure

Use a clear and descriptive URL structure.

 <a href="/en/product?id=123">Voir le produit</a>

 <a href="/en/produits/mon-beau-produit">Voir le produit</a>

3. Accessibility

Accessibility is often overlooked, but it is crucial to providing an inclusive user experience.

ARIA labels

Use ARIA labels to assist assistive technologies.

 <div onclick="maFonction()">Cliquez ici</div>

 <button aria-label="Cliquez pour plus d'informations" onclick="maFonction()">Cliquez ici</button>

Color and Contrast

Make sure the text is easily readable by using sufficient contrast.

 /* Mauvais exemple */
 .texte { color: grey; }

 /* Bon exemple */
 .texte { color: black; }

4. Conclusion

Optimizing your site according to Lighthouse criteria is essential to improve the user experience and therefore increase your conversions and your online visibility.
