How to Automatically Generate Alt Text in WordPress (Step-by-Step Guide)
Adding alt text manually to every image on your WordPress site is time-consuming and easy to skip — but skipping it can hurt your SEO, accessibility, and image visibility on Google.
The good news? You don’t have to write them all yourself.
In this article, we’ll show you how to automatically generate alt text for images in WordPress using AI — in just a few clicks.
Why Generate Alt Text Automatically?
Alt text (alternative text) helps:
- Search engines understand your images
- Screen readers describe content to visually impaired users
- Improve your SEO and accessibility scores
But writing good alt text by hand for every image?
That can take hours.
That’s why many site owners turn to automation — and now, AI makes that smarter and easier than ever.
Step-by-Step: Automatically Add Alt Text in WordPress
Step 1: Install the AI Alt Writer Plugin
First, install and activate the AI Alt Writer plugin from your WordPress dashboard.
It works with the native media library and doesn’t require any complex setup.
Step 2: Activate Your License
Go to the License tab, enter your key, and activate it.
Step 3: Add Your OpenAI API Key
In the ChatGPT Settings tab, paste your OpenAI API key.
(You can generate a key from platform.openai.com.)
You can also choose the language in which your alt text should be generated!
Step 4: Open the Media Library
Once you’re set up, open the plugin interface or media library and see your images listed.
Step 5: Generate Alt Text with One Click
You can:
- Generate alt text and titles for one image
- Select multiple images and click “Generate Selected”
- Use the “Generate All” button to handle your entire library
Bonus: You can even add optional keywords to help guide the AI and make alt text more relevant to your site content.
