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.

How to optimise AI-suggested alt text for every image on your Wix site

• Run a Screaming Frog crawl of your Wix site by entering your domain in Screaming Frog, clicking Start, then navigating to the Images tab. Export the full image list filtered to show images with missing alt text.
• In your Wix Editor, click on any image element on your page, then click the Settings icon (gear) that appears in the image toolbar to open the image settings panel where alt text can be entered.
• Read the AI-suggested alt text and evaluate it with this question: does this description explain why this image is on this page, not just what the image shows? Generic AI descriptions answer the second question, not the first.
• Rewrite generic alt text to be contextually specific: replace "woman typing on a laptop" with "Wix SEO consultant using the Wix AI Blog Writer to generate a content draft" to add topical context and keyword relevance.
• Add your page target keyword naturally into the alt text only when the image directly illustrates that keyword concept. Do not force the keyword into unrelated images; Google treats this as keyword stuffing.
• Keep every alt text under 125 characters so screen readers can read the full description without cutting off mid-sentence. Count characters in your text editor before saving.
• For images that are purely decorative (borders, background patterns, icon dividers), open the image settings panel and leave the alt text field completely empty. Adding alt text to decorative images creates noise for screen readers.
• For product images on Wix eCommerce pages, include the product name, colour or variant, and key feature in the alt text: for example "Navy blue leather Wix store product bag with gold zip, front view".
• For blog post hero images, reference the article topic: for example "Step-by-step Wix SEO dashboard configuration guide screenshot" rather than "person working at a computer".
• After updating alt text across your site, re-crawl with Screaming Frog to confirm missing alt text count has dropped to zero, then check Google Search Console > Search Results > filter by Search Type: Image to monitor growth in image impressions over the following 30 days.

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.

How to Use Wix AI to Generate Alt Text for All Site Images

Use this complete process to audit, generate and refine alt text for every image on your Wix site using AI-assisted tools.

Full image alt text audit and AI-assisted optimisation workflow for Wix sites

• Open Screaming Frog and crawl your Wix site. Once complete, click the Images tab at the top of the window, then click Bulk Export > All Images. This exports a spreadsheet of every image URL, current alt text and which page each image appears on.
• In your spreadsheet, filter the Alt Text column to show blank entries first. These are your highest-priority images. Then filter for very short alt text (under 10 characters) as these are likely inadequate descriptions.
• Log in to your Wix Editor and navigate to the first page on your priority list. Click the Edit Site button to enter editing mode. Click on the first image with missing alt text to select it.
• In the image toolbar that appears, click the Settings icon (gear wheel). In the Image Settings panel, look for the Alt Text field. Wix may display an AI suggestion button next to this field. Click it to generate an initial suggestion.
• Review the AI-suggested alt text. Apply the contextual test: does this description explain why this specific image appears on this specific page? If the AI has written a generic physical description of the image, rewrite it with topical context.
• For every product image, write alt text following this pattern: [Product Name] [Key Feature or Variant] [Context] — for example "Dark oak standing desk with cable management tray, home office setup". Include the product name and a distinguishing detail.
• For every blog post hero image, write alt text that references the article topic rather than the image content — for example "Wix SEO dashboard showing keyword tracking and page performance metrics" rather than "person sitting at a computer".
• For every service page image, include your service name and location if relevant — for example "Wix website design consultation session for a London-based e-commerce client".
• For decorative images (dividers, background patterns, abstract shapes with no informational content), open the image settings and delete any existing alt text, leaving the field empty. Screen readers skip empty alt text on decorative elements.
• After completing all alt text updates on a page, save and publish the changes in Wix. Move to the next page on your priority list and repeat the process. For large sites, work through 5-10 pages per session to maintain quality.
• After updating the entire site, re-run the Screaming Frog crawl to confirm the missing alt text count has dropped to zero. Then monitor Google Search Console > Search Results > filter by Image search type to track growth in image impressions over the next 60 days.
