Well, the same goes for image file names on your website.

Naming your image files something descriptive, related to your content, helps search engines understand what’s in the picture.

Websites with well-named image files have a higher chance of ranking in search results.

Compression is like packing your images efficiently so they don’t take up too much space.

Choosing the right file format for your images is like speaking the language that search engines understand best.

JPEG, PNG, and GIF are common formats, each with its strengths.

JPEG is great for photos, PNG for transparent images, and GIF for simple graphics.

Picking the right format ensures your images are SEO-friendly and load quickly.

About 65% of web pages use JPEG, making it a widely accepted and efficient choice.

However, nowadays WebP format is getting more popular. Consider using this format if possible.

Image Sitemaps and Their Role in SEO

Imagine your website is a big city, and your images are landmarks.

An image sitemap is like a detailed map that guides search engines to every important spot.

It tells search engines what each image is about, helping them index and understand your visual content better.

Page speed is a critical factor in both user experience and SEO.

Tips for Image SEO Success

a. Utilizing Descriptive Filenames

Think of filenames as labels on your image boxes.

This improves the user experience and contributes to faster page speed.

Google recommends lazy loading, and it’s estimated that lazy loading can save up to 60% of bandwidth.

An Image CDN specifically focuses on delivering your image files faster to users around the world.

This reduces server load and speeds up image loading times.
