🤖 Automate your image SEO! Download our free AI Alt Text Writer Plugin to generate accessible, accurate alt tags instantly.

Adding alt text to every image in your WordPress media library is one of the most effective ways to boost image search rankings and ensure screen-reader accessibility. However, manually typing descriptions for hundreds of product photos or blog graphics takes hours.

By using artificial intelligence, you can automate image description entirely. In this step-by-step tutorial, you will learn how to set up automated alt text generation in WordPress to save time and improve your site’s SEO.

Step 1: Install the AI Alt Text Writer Plugin

To start automating your image tags, download and install our lightweight utility:

  1. Download the plugin package from our AI Alt Text Writer Page.
  2. Log into your WordPress dashboard and navigate to Plugins > Add New > Upload Plugin.
  3. Upload the .zip file, click Install Now, and press Activate.

Step 2: Configure Image Analysis Settings

Once activated, configure the plugin to scan your uploads:

  1. Open Settings > AI Alt Text in your WordPress sidebar.
  2. Select your default language and set the description detail level (Concise vs. Detailed).
  3. Enable automatic processing for new media library uploads.

Step 3: Run Bulk Alt Text Generation for Existing Media

If you already have an established website with an existing image library:

  1. Navigate to Media > Library in your WordPress dashboard.
  2. Select the unoptimized images requiring alt tags.
  3. Choose Generate AI Alt Text from the bulk actions drop-down menu and click Apply.

The plugin analyzes the visual elements of each image and inserts natural, contextually accurate descriptions directly into the image meta fields.

Step 4: Verify Alt Text Quality & SEO Relevance

While AI vision models are highly accurate, reviewing your tags ensures optimal quality:

  • Confirm the text describes the image content accurately without keyword stuffing.
  • Ensure screen-reader clarity by avoiding repetitive phrases like “image of” or “photo of”.
