• SVG – Best for logos and icons since they scale without losing quality.
2. Compress Images Without Losing Quality:
Compressing large images can help with reducing file size, while not compromising on image quality. Saving up this space might look little, but it sum up into something relevant in the future. Freeing up this space will give more room for more relevant items.

• Resize images before uploading using tools like Canva, Photoshop, or GIMP.
• Use CSS or HTML to define responsive images for different devices.

Search engines use image file names to understand content. A generic name like “IMG1234.jpg” provides no SEO value.
Solution:

5. Optimize Alt Text for Accessibility and SEO:
Alt text (alternative text) describes an image for search engines and visually impaired users. It helps improve rankings in Google Image Search, as some searchers are only concerned with image files.
Solution:
• Write a clear and concise alt text with relevant keywords.
• Avoid keyword stuffing—make it natural.
Example: Instead of “best discount in hosting“, use “Best hosting packages with 24/7 customer support and discount.”
6. Implement Lazy Loading for Faster Performance:
Lazy loading delays image loading until they are needed, improving initial page load speed. This way you serve users the content they need at each specific part of the blog post while maintaining your SEO effort in the process.
Solution:

<img src=”image.jpg” loading=”lazy” alt=”Descriptive text”>
• Use plugins like Lazy Load by WP Rocket for WordPress.
7. Use Image Sitemaps for Better Indexing:
An image sitemap helps search engines discover and index images faster, increasing their chances of appearing in search results.
Solution:
• If using WordPress, install Yoast SEO or Rank Math to generate an image sitemap.
• Manually add an image sitemap to Google Search Console.
8. Optimize Images for Mobile Users:
A large portion of web traffic comes from mobile devices, so images must be optimized for fast loading on smaller screens. So ensure these images are responsive irrespective of the devices visitors are using to view your site’s contents.
Solution:
• Use responsive images with the srcset attribute:
<img src=”small.jpg” srcset=”medium.jpg 600w, large.jpg 1200w” alt=”Example image”>

JSON-LD format:

“@type”: “ImageObject”,
“contentUrl”: “https://example.com/image.jpg”,
“description”: “Best hosting packages for bloggers and business owners”,
“name”: “Best hosting packages”
}
Add structured data using Google’s Structured Data Markup Helper.
