• Skip it if your store isn't on Shopify, as it installs only from the Shopify App Store
• Not for you if you want time to try it, as there's no free plan and the trial is 3 days
• Pricey if you want prompt tracking, the schema builder or AI posts, which need Premium at $45 a month
• Watch out: only Enterprise, at $345 a month, lists unlimited credits, and limits on the other plans aren't stated

• Tight if you stay free, as alt text stops at 50 products and the 5 AI credits don't renew
• Watch out: audit pages and AI credits beyond your plan are charged on top
• Watch out: Merchant Center recovery and the Ultimate Growth Service are sold separately
• Skip it if your store isn't on Shopify, as it runs nowhere else
