FAQs

Does AltTextLab overwrite existing alt text?

No, by default, AltTextLab only generates alt text for images that currently have an empty or missing alt attribute. Any manually written alt text remains unchanged. Users have an explicit, opt-in option to regenerate alt text across their entire library, including images with existing descriptions.

Can I include specific keywords or product data in the generated alt text?

Yes, AltTextLab allows you to provide custom keywords, product attributes, and brand context. The AI factors these into its output, which is particularly useful for e-commerce, enabling product images to include details like product name, material, color, and category naturally within the description.

How does AltTextLab help with SEO and image search rankings?

AltTextLab improves SEO in two ways: Google uses alt text as a primary signal for ranking images in Google Image Search, and it adds relevant textual context to help Google understand your page's topic. It also affects whether your products appear in LLM-generated recommendations.

What accessibility standards does AltTextLab help with?

AltTextLab helps ensure full compliance with WCAG 2.1 AA, ADA (Americans with Disabilities Act), and EAA (European Accessibility Act) standards. Missing alt text is a frequent failure point for these regulations, and the tool automatically addresses this on every image.

Does AltTextLab offer a free plan or trial?

Yes, AltTextLab offers a free plan that includes 25 image credits, with no credit card required to start. This allows users to test the service and see how it generates alt text before committing to a paid subscription.
