What is ALT Text and How to Use it in My Website
When browsing the web, images often speak louder than words. But what happens when those images don’t show up or someone can’t see them at all? That’s where ALT text steps in. Short for “alternative text,” ALT text is a written description of images that improves accessibility for users with visual impairments and strengthens your website’s SEO. If you’re a local business owner trying to get found online and serve all your customers well, understanding ALT text is a must.

Understanding ALT Text: Purpose and Benefits
What Is ALT Text?
ALT text is a brief HTML attribute attached to an image that describes its content. It exists for two critical reasons: to help those using screen readers understand visual content, and to tell search engines what the image is about.
Why ALT Text Matters for Accessibility
For visually impaired users, ALT text makes the digital world more inclusive. Screen readers read this text aloud so users can understand the image’s message or function. Without meaningful ALT text, you might be unintentionally cutting out a portion of your audience.
SEO Benefits of ALT Text
Search engines like Google can’t “see” your images they rely on ALT text to understand what those images depict. Well-written ALT text improves your rankings in image search results and boosts your overall on-page SEO, making your site more discoverable.
User Experience and Load Failures
If an image fails to load because of a slow connection or broken link, the ALT text is displayed instead. That helps users still understand the page’s intent and layout, especially important on mobile or in areas with poor service.
Writing ALT Text that Works
ALT text isn’t about keyword stuffing or fluffy filler, it’s about being useful, relevant, and respectful of your user’s time and needs.

Tips for Writing Effective ALT Text:
-
Keep it short and focused: 100–150 characters is usually ideal.
-
Describe the purpose, not the format: Don’t say “image of” just describe what it is or what it’s doing.
-
Match the image’s context on the page: Think like your reader what would they want to know?
Different Types of Images and How to Handle Them
-
Decorative images: Use
alt=""
to tell screen readers to skip them. -
Functional images: Describe what the image does. Example: “Search icon” or “Add to cart button.”
-
Informative images: Provide a summary of the key content, like “Chart showing sales growth from 2019 to 2023.”
-
Complex images: Use short ALT text and offer a more detailed description nearby or link to a longer explanation.

-
