Image Alt Tag Checker

What Is an Alt Tag?

An alt tag (alternative text) is used inside an image tag to describe what the image is. It improves SEO and ensures accessibility for users who rely on screen readers.

Why Alt Tags Matter

Search engines can’t "see" images — they rely on alt text to understand them. Alt tags:

• ✔ Improve search engine indexing
• ✔ Make your website more accessible
• ✔ Help with Google Image Search rankings
• ✔ Act as fallback text if the image doesn’t load

Best Practices

• ✔ Accurately describe the image content
• ✔ Don’t stuff with keywords
• ✔ Use empty alt="" only for purely decorative images
• ✔ Avoid duplicate alt texts across images
