What are the best practices for using alt attributes for images in US SEO?

Alt text (alternative text) isn’t just a box to check off when uploading an image. It’s a powerful tool that enhances your website’s accessibility, user experience, and search engine optimization (SEO). For US SEO, where competition is fierce, well-crafted alt text can give you an edge in image search results, driving more traffic to your site.

Best Practices

• Be Descriptive and Specific:

  • Clearly describe what’s in the image. Don’t just say “photo of a dog,” but rather “Beagle puppy playing fetch in a sunny park.”
  • Imagine you’re describing the image to someone who can’t see it.

• Keep it Concise:

  • Aim for 125 characters or less. Most screen readers stop reading alt text after that limit.
  • Prioritize the most important details.

• Context is Key:

  • Relate the alt text to the content of the page. If it’s a blog post about healthy dog treats, your alt text might be “Close-up of a Beagle puppy eagerly eating a carrot.”

• Keyword Usage: Naturally incorporate relevant keywords, but don’t overdo it. Search engines are sophisticated; keyword stuffing can hurt your rankings. Think about the terms people would use to search for your content, and include those where appropriate.

• Avoid Redundancy:

  • If the surrounding text already describes the image, a simple alt text like “Beagle puppy” can be sufficient.

• Decorative Images:

  • Use null alt text (alt=””) for purely decorative images that don’t add informational value. This tells screen readers to skip them.

Unique Tips from Experience:

• Think Like a User: Consider what information someone would want if they couldn’t see the image. Does the image have a specific purpose (like demonstrating a product feature), or is it more atmospheric?
• Don’t Forget Image File Names: Name your image files descriptively (e.g., “beagle-puppy-eating-carrot.jpg”). This provides another signal to search engines about the image’s content.
