Buyer comparison
How to compare Shopify SEO agencies
Shopify stores lose organic visibility to duplicate collection-path product URLs, unindexed sub-category demand, and third-party apps that slow down mobile product pages. Compare Shopify SEO agencies on how they work inside Liquid templates and measure organic orders.

Short answer: Pick a Shopify SEO agency by checking whether it fixes `/collections/*/products/*` canonical links in the Liquid theme, builds indexable collection pages for non-brand product searches, and audits app script weight.
What to compare before you choose
Collection page architecture
Check how the agency maps commercial search demand into new collections and sub-collections rather than relying on blog posts alone.
App bloat and order reporting
Confirm that the team audits third-party app scripts for mobile speed and reports organic revenue from Shopify analytics and Search Console.
