4. Add Alt Text for Accessibility and SEO

The alt text describes the image for search engines and visually impaired users. A reasonable alt tag is concise, descriptive, and includes relevant keywords, like: "A pair of blue running shoes on a track, ideal for marathon training."

5. Optimize Image Loading with Lazy Loading

Lazy loading ensures images load only when they appear in the user’s viewport, reducing initial page load time and improving performance. Implement it using the loading="lazy" attribute in HTML.

A CDN distributes images across multiple servers globally, reducing load times for users in different locations. Services like Cloudflare, BunnyCDN, or Amazon CloudFront help optimize image delivery.

        11. How to check your website images

        Ensuring that your images are properly optimized is a key part of SEO optimization for images. If your website images are too large, missing alt text, or not indexed by search engines, they can slow down your site and hurt your rankings. Here’s how you can check your website images for SEO performance and fix any issues.

        A. Check Image File Size & Format

        Large image files slow down page speed, which negatively affects SEO. Use tools like:

        • Google PageSpeed Insights (pagespeed.web.dev): Analyze your website speed and identify unoptimized images.
        • GTmetrix (gtmetrix.com) provides detailed performance reports, including image-related issues.
        • TinyPNG (tinypng.com): Helps compress large image files without losing quality.

        B. Verify Image Alt Text & Descriptions

        Alt text improves accessibility and helps search engines understand images. To check for missing or poorly written alt text, use:

        • Google Search Console: Under Coverage Report, look for "Image issues" to find missing alt attributes.
        • Screaming Frog SEO Spider (screamingfrog.co.uk): Scans your site and lists images missing alt text.

        C. Check If Your Images Are Indexed by Google

        If your images aren’t indexed, they won’t appear in Google Image Search. To check:

        • Search "site:yourwebsite.com" in Google Images to see which images are indexed.
        • Use the Google Search Console → Image Indexing report to identify indexing problems.

        D. Test Mobile Friendliness and Lazy Loading

        Images should load quickly on mobile devices. You can check for mobile issues using:

        • Google Mobile-Friendly Test (search.google.com/test/mobile-friendly)
        • Ensure lazy loading is enabled by inspecting images in Chrome Developer Tools (Ctrl + Shift + I → Network tab → check if images load as you scroll).

        E. Validate Open Graph & Social Media Image Tags

        To check if your images appear correctly when shared on social media:
