How to automate alt text?
You can automatically generate alt text using AI-powered tools like AltTextLab. It analyzes your images, including objects, scenes, and context, and creates clear, descriptive alt text optimized for SEO and accessibility. AltTextLab supports bulk processing and integrates with various platforms, including WordPress, Shopify, WooCommerce, Webflow, and more. You can also connect it to thousands of apps via Zapier or Make, or use the Chrome extension to generate alt text on any website.
Does product image alt text help Shopify SEO and AEO?
Yes, in two ways. First, alt text helps Google Image Search understand and index your product images, which can drive meaningful additional organic traffic (especially for visual products like clothing, furniture, and accessories). Second, AI tools like ChatGPT and Google AI Overviews use alt text to understand your images when generating product recommendations or shopping answers. Without descriptive alt text, your products are effectively invisible to those systems, regardless of how well your text content ranks.
How to create a good alt text?
A good alt text clearly and concisely describes the essential content and function of an image. It should be specific, relevant, and help users understand the image, even if they can't see it.
✅ Good Example:
A red running shoe on a white background.
❌ Bad Example:
Image123.png or Doctor
Tips for good alt text:
- Describe what’s happening, not just what’s shown.
- Avoid using phrases like “image of” or “picture of.”
- Focus on the purpose of the image within the context of the page.
- Keep it short but informative.
AltTextLab helps automate this process using AI trained to follow best practices in accessibility and SEO.
