Images make a website more engaging, but they also need to be understood by search engines and assistive technologies. That’s where alt text (alternative text) comes in. Whether you’re running a business website, an online store, or a personal blog, adding descriptive alt text to your images is a simple step that can improve accessibility and strengthen your SEO.
In this guide, you’ll learn what alt text is, why it matters, how to write effective alt text, and how to add it to images in WordPress.
What Is Alt Text?
Alt text, short for alternative text, is a written description added to an image. If an image cannot be displayed or if a visitor uses a screen reader, the alt text provides a description of what the image represents.
For example:
Good Alt Text: A web designer creating a landing page using Elementor in WordPress.
This gives both users and search engines useful context about the image.
Why Is Alt Text Important?
Alt text serves several important purposes beyond simply describing an image.
1. Improves Accessibility
Visitors who rely on screen readers cannot see images. Alt text allows assistive technology to describe the content, making your website more accessible to everyone.
2. Helps Search Engines Understand Images
Search engines cannot interpret images the same way humans can. Alt text helps explain what an image contains, allowing it to be indexed more accurately.
3. Supports Image Search Visibility
Well-written alt text can increase the chances of your images appearing in search results, helping bring more visitors to your website.
4. Creates a Better User Experience
If an image fails to load due to a connection issue, the alt text is displayed instead, giving visitors an idea of what should have appeared.
When Should You Add Alt Text?
Not every image needs a detailed description, but most informative images should include alt text.
You should add alt text for:
Product photos
Team member photos
Blog illustrations
Infographics
Screenshots
Service-related images
Decorative images that provide no meaningful information can often use empty alt text so screen readers skip them.
Best Practices for Writing Alt Text
Writing effective alt text is simple when you follow a few guidelines.
1. Describe the Image Clearly
Write a short description that explains what the image shows.
a. Good Example
Electrician installing wiring inside a commercial building.
b. Poor Example

2. Keep It Concise
Most alt text should be one or two short sentences. Include enough detail without becoming overly descriptive.
3. Include Keywords Naturally
If your page targets a keyword, it’s fine to include it when it accurately describes the image.
For example:
Elementor editor creating a responsive homepage layout
Avoid forcing keywords into every image.
4. Don’t Start with “Image of…”
Screen readers already identify images, so phrases like “Image of” or “Picture of” are unnecessary.
Instead of:
Image of a laptop.
Use:
Laptop displaying the WordPress dashboard.
5. Match the Context of the Page
The same image may require different alt text depending on the topic of the page.
If an image appears in an SEO article, describe it in relation to SEO. If it appears in a web design tutorial, focus on the design aspect.
Common Alt Text Mistakes
Many website owners make these mistakes:
Leaving alt text blank.
Stuffing multiple keywords into one description.
Writing descriptions that are too long.
Using file names as alt text.
Writing unrelated descriptions.
Keeping your descriptions natural and relevant will provide a better experience for users and search engines.
Examples of Good and Bad Alt Text
| Image | Good Alt Text | Poor Alt Text |
|---|---|---|
| Laptop with Elementor open | Designer editing a homepage using Elementor | laptop.jpg |
| Team meeting | Engineering team discussing a construction project | team meeting office business people company team |
| Product image | Stainless steel pipe fitting for industrial use | Product |
How to Add Alt Text in WordPress
Adding alt text in WordPress only takes a few steps.
Log in to your WordPress dashboard.
Open Media → Library.
Select the image you want to edit.
Find the Alternative Text field.
Enter a clear description of the image.
Save your changes.
Any time the image is used on your website, WordPress can apply this alt text.
How to Add Alt Text in Elementor
If you’re using Elementor, adding alt text is just as easy.
Open the page with Elementor.
Select the Image widget.
Choose or upload an image from the Media Library.
If the image already has alt text saved in WordPress, Elementor can use it automatically.
Update the page after making changes.
It’s good practice to add alt text in the Media Library before using the image across multiple pages.
Tips for Better Image SEO
Alt text is only one part of image optimization. You can further improve your website by:
Using descriptive image file names.
Compressing large images before uploading.
Choosing modern image formats such as WebP.
Setting image dimensions correctly.
Using responsive images for mobile devices.
Adding captions when they provide additional context.
These practices can improve both website performance and search visibility.

Final Thoughts
Alt text may seem like a small detail, but it plays an important role in creating a website that is accessible, user-friendly, and search-engine optimized. By describing your images clearly, avoiding keyword stuffing, and following best practices, you can improve both the visitor experience and your site’s visibility in search results.
