Plug In SEO charges $0–29/mo for meta tag editing, structured data, and broken link detection. Build your own SEO management app with Shopivibe — schema markup, sitemap generation, and meta optimization all included.
Most Shopify SEO wins come from meta titles, descriptions, structured data, and sitemaps — things you can build directly into your theme and app. Paying $29/mo for an editor that wraps Shopify's existing API isn't necessary.
