What is alt text? A practical guide for WordPress

Why Alt Text Matters More Than Ever

Alt text (alternative text) is a short snippet of copy stored inside the HTML <img> tag as the “alt” attribute. While sighted users see the photo, search engine spiders and assistive screen-readers rely exclusively on this text to understand what the graphic depicts.

Without alt text, Google has to guess what your image contains based on nearby paragraphs, which frequently leads to lost rankings in Google Images and AI overview summaries.

What Good Alt Text Looks Like

A common mistake is writing generic or keyword-stuffed alt attributes. Screen readers read every single word aloud to visually impaired visitors.

Consider a photograph of a barista pouring coffee:

• ❌ Bad: alt="IMG_2041.jpg" (Useless filename)
• ❌ Bad: alt="coffee beans espresso latte coffee cafe beans cheap buy" (Spammy keyword stuffing)
• ⚠️ Mediocre: alt="coffee" (Too vague to be informative)
• ✅ Perfect: alt="Barista pouring steamed milk into a white ceramic cup to form latte art" (Specific, helpful, natural)

Automating Your WordPress Media Library

Writing alt text manually for 5 or 10 images is manageable. But for WooCommerce stores with thousands of product shots or busy magazine publishers, manual alt text takes hundreds of hours.

Using a dedicated AI generator lets you automatically analyze uploaded images using computer vision, generating accurate, contextual descriptions, captions, and titles in seconds.
