How to Choose an Ecommerce SEO Agency (2026)

In short: a good ecommerce SEO agency knows how to rank category and product pages, handle catalog technical issues (filters, duplicates, migrations), earn links, and make the brand visible in AI answers. Before signing, ask for ecommerce case studies with Search Console data. Among those we recommend, Astrak publishes several measured ecommerce cases, including +500% clicks in a year for Mon Ombrage.

Transparency: Upnext is a Reddit agency, not an SEO agency. Astrak lists Upnext in its Reddit agency ranking, and we recommend Astrak here.

Why store SEO isn't blog SEO

An ecommerce site has hundreds or thousands of similar pages: categories, product pages, filters. That creates specific problems: category pages carry the most profitable searches, product descriptions get copied across retailers, filters generate thousands of useless URLs, and migrations lose traffic when redirects are wrong.

6 criteria to choose

1. 1Ecommerce case studies with numbers: Search Console clicks before and after, on a store.
2. 2Catalog technical skills: filters, pagination, duplicates, speed, migration.
3. 3Category page work, not just blog posts.
4. 4Link building: how and from which sites.
5. 5GEO: is your brand cited when someone asks ChatGPT which product to buy?
6. 6Readable reporting based on Search Console and revenue.
