The Herbalist review for Webrex: AI SEO Schema, JSON‑LD

Feb. 12, 2026

I’ve been using Webrex SEO Schema & JSON-LD for my Shopify store and honestly it’s one of the best free SEO apps available. The setup was incredibly simple no coding needed and it immediately fixed structured data issues on my product pages, including missing product ID and schema errors in Google. What I like most is that it automatically generates clean, valid JSON-LD for products, breadcrumbs, and rich snippets. After installation, my store passed Google’s Rich Results Test without warnings, which gave me a lot of confidence in my SEO structure. For a free app, the features are surprisingly powerful. It runs smoothly, doesn’t slow the site, and works perfectly in the background. If you’re running a Shopify store and want to fix schema issues or improve search visibility without paying monthly fees, this app is a must-have. Highly recommended for anyone serious about SEO.
