Alt text makes images accessible and searchable. Add clear descriptions so users and search engines understand your content, even without visuals.
Not every user experiences your website the same way.
Some can't see your images. Others rely on screen readers to navigate your content. And search engines? They can't "see" visuals at all.
Alt text bridges that gap.
It makes your images understandable, accessible, and searchable without changing how they look.
Alt text (alternative text) is a written description added to an image in your website's code.
It explains what the image shows so screen readers and search engines can understand it.
For example:
Instead of just uploading an image, you describe it:
"Woman using a laptop to analyze website analytics dashboard"
It's invisible to most users, but critical behind the scenes.
Accessibility isn't optional.
Alt text ensures that users who rely on assistive technology can still understand your content. Without it, images become dead space.
It also improves SEO. Search engines use alt text to understand what your images represent, which can help your content appear in search results.
And when images fail to load, alt text provides context instead of leaving users guessing.
Product Images
Help users understand what they're buying, even without visuals.
Blog and Content Images
Add context to support your written content.
Navigation and UI Elements
Ensure icons and buttons are accessible to all users.
SEO and Image Search
Improve discoverability by giving search engines meaningful descriptions.
Be Descriptive, Not Generic
"Image of a product" doesn't help. Describe what's actually shown.
Keep It Concise
Clear and to the point. No need for long sentences.
Focus on What Matters
Describe the key elements relevant to the content, not every tiny detail.
Avoid Keyword Stuffing
Write for clarity, not search engines. Overloading keywords hurts more than it helps.
Skip Decorative Images
If an image adds no meaning, use empty alt text so screen readers can ignore it.
Alt text isn't just a technical detail.
It's about inclusion.
It ensures your website works for more people, in more situations, while also improving how your content is understood by search engines.
And when your site is accessible, clear, and searchable, everyone benefits.
