AI image generation and alt text optimisation on Wix

Wix offers AI image generation and AI-suggested alt text for your visual content. This lesson covers how to use these tools effectively for image SEO while avoiding the pitfalls of generic AI-generated visuals and descriptions.

Wix AI Image Generator for Content

The Wix AI image generator creates images from text prompts. For SEO purposes, AI-generated images are generally inferior to original photography, screenshots and custom graphics. Search engines cannot distinguish AI images from real ones yet, but users can, and user engagement signals affect rankings.

When to Use AI Images vs Original Images

• Use AI images for: decorative headers, abstract concepts, placeholder visuals during content development
• Use original images for: products, team photos, case study screenshots, location photos, before/after comparisons
• Use custom graphics for: data visualisations, process diagrams, infographics, comparison charts
• Never use AI images for: product listings, team pages, testimonial photos, location-specific content

AI-Powered Alt Text Generation

Wix can suggest alt text for your images using AI analysis. This is helpful for sites with hundreds of images that lack alt text. However, AI-generated alt text tends to be generic descriptions of what the image shows rather than contextual descriptions of why the image matters on that page.

Optimising AI-suggested alt text

• Enable AI alt text suggestions in your Wix media settings
• Review each suggestion and ask: does this describe the image in context of the page?
• Add your target keyword naturally if the image directly relates to the topic
• Keep alt text under 125 characters for screen reader compatibility
• Replace generic descriptions like "woman at desk" with specific ones like "SEO consultant reviewing Wix analytics dashboard"
• Leave decorative images with empty alt text (alt="") rather than adding descriptions

Bulk Alt Text Audit and Update

Run a Screaming Frog crawl of your Wix site filtered to images. Export the list of images with missing or duplicate alt text. Use AI to generate initial alt text for each, then manually review and refine them in batches. This is significantly faster than writing every alt text from scratch.
