Let’s imagine you’ve just uploaded a stunning image to your WordPress website. You’re proud of it, and it’s the perfect visual to represent your content. But wait—what happens when someone who’s visually impaired visits your site? How do they experience that image? That’s where alt text (short for alternative text) comes in. It’s not just a small box you check off when adding an image; it plays a significant role in making the web more inclusive.
Let’s dive into why alt text is important, how it came to be, and how you can use it to ensure your WordPress site is accessible to all.

What is Alt Text, and Why Should You Care?
Alt text is a brief description of an image that allows visually impaired users to understand what the image represents through the help of screen readers. When someone can’t see an image, whether due to a disability or a slow internet connection, the alt text steps in as the “voice” of the image. It describes what’s there, providing a similar experience to everyone, no matter their situation.
But it’s not just about accessibility. Alt text also boosts your SEO by allowing search engines to better understand your content. It’s a win-win: you help create an inclusive digital space while making your site more discoverable.
A Brief History of Alt Text
Alt text wasn’t always a web standard. It emerged as the internet grew and more people began to recognize the need for digital accessibility. Back in the early days of the web (think the 1990s), the internet was a simpler place—mostly text and basic images. As websites grew more complex, web developers and advocacy groups realized that they needed a way for people with disabilities to access visual content.
Enter the Web Content Accessibility Guidelines (WCAG), first published in 1999 by the Web Accessibility Initiative (WAI). These guidelines aimed to make the web more inclusive by setting standards, and alt text became one of those key elements. By following the WCAG, websites can meet accessibility requirements, ensuring that people with disabilities have equal access to content.
It’s amazing how far we’ve come, but we’re still on a journey toward full accessibility. In 2024, alt text is now standard practice, but many websites still fall short.

Why Does Alt Text Matter for Accessibility?
When we talk about accessibility, we’re referring to designing your website in a way that everyone—including people with disabilities—can use and enjoy it. Visual impairments are more common than you might think, and the experience of the internet shouldn’t be limited by sight.
Imagine visiting a website full of images but having no way to understand what they are because you rely on a screen reader. That’s a frustrating experience for someone with a visual impairment. Alt text makes sure that no one is left out by providing a clear, concise description of what’s going on in the image.
Let’s not forget that accessibility doesn’t just help people with permanent disabilities. It can also assist people in temporary situations (like having a broken arm and being unable to use a mouse) or situational impairments (like trying to read your website on a sunny day with glare on their screen).

How to Write Effective Alt Text: Practical Tips
Writing alt text is more of an art than a science. You want to be descriptive without being too wordy, and you need to think about what’s important in the image. Here are a few tips to help you write alt text that enhances accessibility:
1. Be Descriptive, But Concise
Alt text should give enough detail to help someone understand the image but should avoid unnecessary details. If you’re adding an image of a dog sitting on a beach, “A golden retriever sitting on the sand at sunset” would be far more useful than just “dog on the beach.”
2. Include the Context
Think about why the image is there. Is it purely decorative, or does it add value to your content? If the image is an important part of your story or article, explain its relevance. For example, if you’re writing a blog post about travel, and you include a photo of the Golden Gate Bridge, your alt text should reflect the context: “Golden Gate Bridge at sunrise, illustrating a perfect start to a travel adventure in San Francisco.”
3. Avoid “Image of” Phrases
There’s no need to say “image of” or “picture of” in your alt text—it’s already implied. Jump straight to the description.
4. Think About SEO, But Don’t Overstuff
Alt text can indeed help improve your SEO because it gives search engines more information about the content of your page. However, stuffing alt text with keywords will not only hurt your SEO in the long run but also degrade the user experience for those using screen readers. Write naturally and prioritize accessibility first.
5. Use Alt Text for Functional Images
Some images are functional, like buttons or icons. For these, the alt text should explain the function. For instance, for a search icon, you could use alt text like “Search” to tell users what clicking the icon will do.

Real-Life Examples of Alt Text in Action
Let’s look at a couple of examples to see how alt text works in practice:
Example 1: Bad Alt Text
Image of a person holding a cup of coffee.
- This doesn’t tell us much, does it? We don’t know what’s important or why the image is even included.
Example 2: Good Alt Text
A woman smiling while holding a coffee cup in a cozy café represents a relaxing moment.
- This tells us much more and provides context. Now we know that the person is enjoying a relaxing moment, which is likely tied to the overall mood or message of the content.

Going Beyond Alt Text: Making Your WordPress Website Fully Accessible
Alt text is just one piece of the accessibility puzzle. To make your WordPress website fully inclusive, consider other aspects like:
- Use clear and accessible language throughout your content.
- Ensuring your site is navigable with a keyboard.
- Adding captions and transcripts to multimedia content like videos.
- Utilizing headings and proper structure for better readability and screen reader compatibility.
Thankfully, WordPress makes this easier by offering a range of plugins designed to improve accessibility. Plugins like WP Accessibility and AccessibleWP can help you audit your site for accessibility improvements.
Why Alt Text Should Be a Priority for Your WordPress Website
Alt text isn’t just a small detail you can overlook—it’s a vital tool in making the web a more inclusive place for everyone. Whether you’re running a blog, an e-commerce store, or a corporate website, taking the time to craft thoughtful, descriptive alt text will ensure that no one is left behind.
Not only does this improve the user experience for people with visual impairments, but it also helps your SEO and overall website performance. In 2024 and beyond, accessible content is more important than ever, and it’s up to all of us to create a digital space that everyone can enjoy.
So, next time you upload an image to your WordPress site, take a moment to think about the person who won’t be able to see it—because with well-written alt text, they can still be part of the experience.
