- Technical SEO: Optimized Content for Featured Snippets
- Featured snippets, also known as position zero, are snippets of content that appear at the top of organic search results.

Example:
Optimizing Loading Speed with Image Compression In this example, let's imagine you run an e-commerce website selling clothes. High-resolution images of your products can slow down the loading time of your pages, which can adversely affect the user experience and your ranking in search results. To solve this problem, you can compress images to reduce their size without compromising their visual quality. Code : Here is an example of Python code using the Pillow library to compress an image:# Ouvrir l'image à compresser image = Image.open("chemin/vers/votre/image.jpg") # Compression avec un facteur de qualité de 50 (réglable selon vos besoins) image.save("chemin/vers/votre/image_compressée.jpg", quality=50) print("L'image a été compressée avec succès !")
Explanation:- First, we import the Image class from the Pillow library, which allows us to manipulate images. Next, we open the image we want to compress, specifying its path and using the method
save()to save the compressed image under a new file name with a quality factor of 50. This factor can be adjusted to suit your specific needs. Finally, we display a message confirming that the compression operation has been completed successfully.
By compressing your website's images, you can significantly improve page loading speed, offering a better user experience and increasing the chances of higher search result rankings.
