SEO-Friendly ALT Text with Compressed Images

Writing strong ALT tags is more than just accessibility—it’s a vital SEO tactic. When paired with compressed images, your site benefits from both performance and ranking. Whether you're running a blog, affiliate site, or eCommerce store, image optimization with ALT text improves search visibility and page experience.

ALT tags help search engines understand images. When they’re paired with lightweight, compressed formats like WebP or JPEG (optimized via tools like ProCompressor), your images load fast and rank better in Google Images and Web Search.

What Are ALT Tags?

ALT (alternative) text is the attribute used inside an image tag to describe the content of the image. It serves two core purposes:

  • ✅ Accessibility for screen readers
  • ✅ SEO for image indexing and ranking

Best Practices for SEO-Friendly ALT Text

  1. Describe the image clearly and specifically
  2. Use relevant keywords naturally
  3. Avoid keyword stuffing
  4. Keep it under 125 characters
  5. Use dashes (-) instead of underscores (_) in file names

Why Combine ALT Tags with Compression?

Compressed images reduce file sizes, speeding up load time. When these lightweight images also have descriptive ALT tags, search engines can better rank and serve them in search results—boosting visibility without sacrificing performance.

Example: Before vs. After

Before:

<img src="image1.jpg">

After:

<img src="compressed-image.webp" alt="infographic showing image optimization tips">
