The honest take
Plug In SEO has been a reliable Shopify SEO staple since 2014 — it's trustworthy for issue detection and meta tag templates. But it was built before AI generation became viable. Sauron takes over from where issue detection stops: AI generates brand-voice-calibrated titles, keyword research validates real search volumes, and a backlink network builds authority automatically. If you've already fixed the basics and want SEO to move the needle, Sauron picks up where Plug In SEO leaves off.

Common questions
Is Plug In SEO still worth using in 2026? +
For basic SEO issue detection, yes — it's reliable and well-maintained. But it hasn't kept pace with the shift to AI-generated copy. If your priority is scaling SEO across a large product catalog without manual work per product, a more modern tool like Sauron is a better fit.
Can I use Plug In SEO and Sauron at the same time? +
You can, but disable Plug In SEO's meta tag writing features to prevent conflicts. Sauron should be the single source of truth for meta titles and descriptions. If you want to keep Plug In SEO running for issue detection, that won't conflict with Sauron's AI generation.
Will I lose rankings when switching from Plug In SEO to Sauron? +
No. Your published meta titles and descriptions stay live on Shopify — switching apps doesn't change what's on your pages until you publish new content. Sauron lets you review AI-generated copy before publishing, so you stay in control of the transition.
Does Sauron detect the same SEO issues as Plug In SEO? +
Sauron's store scan identifies missing meta tags, duplicate titles, thin content, and image alt text gaps — covering the most impactful issues Plug In SEO flags. Plug In SEO has a longer issue list including some edge cases, but the high-priority issues overlap significantly.
