  • The ready reckoner for how Image Optimization can be done on the website:

  • JPEG: Best for photographs and images with many colors.

3. Descriptive File Names

Using descriptive, keyword-rich file names helps search engines understand the content of the image. For example, instead of IMG_1234.jpg, use golden-retriever-puppy.jpg.

4. Alt Text (Alternative Text)

Alt text provides a text alternative to images when they cannot be displayed. It is also used by screen readers for accessibility and helps search engines understand the image content.

 Example: <img src="golden-retriever-puppy.jpg" alt="Golden Retriever puppy playing in the grass">

5. Image Sitemaps

Including images in an XML sitemap helps search engines discover and index images on your site.

6. Responsive Images

Using responsive images ensures they display correctly on various devices and screen sizes. HTML5's srcset attribute can be used to specify different image versions for different screen resolutions.

7. Lazy Loading

Lazy loading delays loading images until they are in or near the viewport. This improves page load speed, which can positively impact SEO.

8. Image Dimensions

Specify image dimensions to reduce page layout shifts as the page loads. This also helps browsers allocate space while loading the images.

9. Structured Data

Use structured data (schema markup) to provide additional information about images, enhancing search engines' understanding.

10. Captions and Context

Adding captions and placing images near relevant text can help search engines understand the context of the images.

By implementing these practices, the visibility and performance of images on search engine results can significantly increase, contributing to overall SEO for the website
