Alt text should be empty when an image is purely decorative and does not add useful information to the page. In HTML, this is usually written as alt="".
For the broader workflow, see WordPress Image Accessibility: Fix Missing Alt Text at Scale.
This does not mean the image is broken or ignored by mistake. Empty alt text can be the correct accessibility choice when the image does not need to be announced by screen readers.
This topic belongs under the broader WordPress image accessibility guide.
What Empty Alt Text Means
Empty alt text means the alt attribute exists but has no descriptive value:
<img src="divider.png" alt="">
This is different from a missing alt attribute. A missing alt attribute can create ambiguity. An empty alt attribute tells assistive technology that the image can be skipped.
For the technical difference between image attributes, use the alt attribute vs title attribute article.
Decorative vs Informative Images
Use empty alt text for decorative images such as:
- visual dividers
- background flourishes
- repeated icons that are explained by nearby text
- layout-only graphics
- decorative borders or shapes
Use descriptive alt text for informative images such as:
- product images
- screenshots
- charts
- diagrams
- photos that support the article meaning
- images used as links or buttons
WordPress Examples
Decorative image:
- A swirl divider between two sections
- Recommended alt text:
alt=""
Informative image:
- A screenshot showing missing alt text fields in WordPress
- Recommended alt text:
WordPress media library showing empty alt text fields
Product image:
- Recommended alt text:
Black leather office chair front view
Functional Images and Linked Images
An image is not decorative when it performs an action. An icon used as a button, an image inside a link, or a logo that links to the homepage may need a text alternative that communicates the function rather than only describing its appearance.
For example, a magnifying-glass icon used to submit a search should communicate the action Search, not merely magnifying glass. If visible link text already provides the same purpose, repeating it in the image alt text may create unnecessary duplication. Review the complete link or control, not the image in isolation.
What About CSS Background Images?
Design flourishes and textures are often implemented as CSS backgrounds. Because they are not content images in the HTML, they do not use an image alt attribute. That is appropriate when the background is decorative.
If a background image communicates essential information, the information still needs an accessible text equivalent in the page content. Moving an important message into CSS does not make the message decorative.
Context Can Change the Decision
The same image file can be decorative in one place and informative in another. A stock photo beside a heading may add no new meaning, while the same photo in a case study may be evidence that requires description. WordPress attachment metadata alone cannot always determine this context. The final page placement and purpose control the decision.
Does Empty Alt Text Hurt SEO?
Empty alt text is not automatically bad for SEO. If the image is decorative, forcing keyword-rich alt text can make the page worse for accessibility and quality.
SEO should not override accessibility. Important images should have useful alt text. Decorative images can be empty.
Decision Checklist
Before leaving alt text empty, ask:
- Does the image add information not already available in nearby text?
- Is the image part of a link, button, or control?
- Would removing the image change the user’s understanding or ability to act?
- Is the image evidence, a product view, a chart, or an instructional screenshot?
- Is nearby text already communicating the same function or meaning?
If removing the image changes nothing, empty alt text may be appropriate. If the image changes meaning or function, provide a useful text alternative.
Automation Caution
Automation should not blindly fill every empty alt text field. Some empty alt text values may be intentional. A good workflow should separate decorative images from informative images where possible.
If you manage WordPress image alt text at scale, use rules carefully and review important templates before applying changes across a site.
FAQ
Is empty alt text the same as missing alt text?
No. Empty alt text is intentional: alt="". Missing alt text means the alt attribute is absent or not defined.
Should decorative WordPress images have alt text?
No. If an image is purely decorative, empty alt text is usually the right choice.
Should product images ever have empty alt text?
Usually no. Product images are informative and should normally describe the visible product.
