What are Captions?
Captions are short texts that appear below or next to images in WordPress. They help users understand more about the image and its context.
Definition and Purpose
A caption is a brief text that goes with an image. It:
- Explains what’s in the image

Captions make images more useful by helping readers understand why the image is important.
Captions vs Alt Text
| Feature | Captions | Alt Text |
|---|---|---|
| Visibility | Seen by all users | Only for screen readers or when images don’t load |
| Length | Can be longer | Usually short |
| Purpose | Give extra info | Describe image for accessibility |
| SEO impact | Less direct | More direct |
Writing Good Captions
To write good captions:
- Keep them short and clear
- Add info not already in the image
- Use names and key words that fit the content
- Don’t repeat what’s in the alt text
- Write like you’re talking to a friend
Example:
| Good Caption | Bad Caption |
|---|---|
| "John Smith, CEO, speaking at the 2023 Tech Conference" | "Image of a man talking" |
| "New York skyline at sunset, featuring the Empire State Building" | "City view" |
What are Descriptions?
Descriptions are longer explanations of images used on websites and social media. Unlike alt text, descriptions are visible to all users and give more details about the image.
Definition and Purpose
In WordPress and other media platforms, descriptions are fields where you can add extra information about an image. This info doesn’t show up on your website’s front page but helps with organizing and managing your images.
How Descriptions Work with Alt Text and Captions
| Element | Purpose | Visibility |
|---|---|---|
| Alt Text | Brief description for accessibility | Screen readers only |
| Captions | Quick info about the image | All users |
| Descriptions | Detailed explanation | Not shown on front-end |
These three elements work together to give a full picture of an image.
Writing Useful Descriptions
To write good descriptions:
- Be detailed and specific
- Include info about the subject, location, and context
- Use keywords naturally to help with search engines
Here’s an example:
| Good Description | Bad Description |
|---|---|
| "Group of friends hiking in Yellowstone National Park mountains, with sunset in background. Photo taken in 2022." | "People outdoors" |
This kind of description helps users understand the image better and can make your website easier to find online.
