AltMaster writes ALT text for every product, variant, and collection image in your store, in one bulk run. Get found in Google search, Google Shopping, and AI assistants like ChatGPT and Perplexity.
Google can't see pixels. ChatGPT can't see pixels. Perplexity can't see pixels. They read ALT text, and when it's missing, your product simply doesn't exist to them.
A typical Shopify store with 200 products has 600–1,500 images once you count variants. Manually writing ALT text for each one takes 40+ hours.
Most stores never do it. Most stores quietly lose traffic, to Google, to Google Shopping, and now to every AI assistant that shoppers are asking instead.
AltMaster collapses that 40-hour weekend into a 3-minute bulk run.
Start Optimizing Your ALT Text →When someone asks ChatGPT for "a linen shirt under $80" or Perplexity for "leather totes from indie brands," the AI reads ALT text to decide which products to recommend. No ALT text means no recommendation.
AltMaster scans your catalog in seconds and shows you exactly how many products, variants, and collection images are missing ALT text.
Drag in variables: product title, variant, vendor, tags, type. Watch a live preview so you know the exact ALT text you'll generate before you commit.
Hit Generate. ALT text gets written directly into Shopify across every product, variant, and collection. Re-run anytime you add new products.
Mix and match these variables to create ALT text that matches the way you describe products. No generic output, no awkward phrasing.
Drop variables into a template, add your own connecting words ("in," "by," "from"), and AltMaster fills in the rest from your actual Shopify product data.
Start Optimizing Your ALT Text →WooCommerce, BigCommerce, Magento. Migrations strip ALT text. AltMaster restores image SEO across your whole catalog in one run, so you don't lose ranking during the move.
Apparel, accessories, anything with 5–20 colors and sizes per product. Variant-specific ALT text means each color and size can rank on its own keywords.
