11 Best Shopify SEO Agencies in 2026 (USA): Pricing, Contracts & Red Flags

The best Shopify SEO agency fixes Shopify's platform-specific problems (duplicate product URLs, thin collection pages, app bloat) in your theme code, builds collection-page content and links, covers AI search and Google Shopping, and reports on non-branded organic revenue, not rankings. Below are 11 Shopify SEO agencies worth a US shortlist, what they charge, and the questions that expose generalists. Disclosure: we're a Shopify SEO agency and we include ourselves, clearly labelled. Everything else comes from what each agency publishes about itself as of October 2026.

What does a Shopify SEO agency do?

A Shopify SEO agency grows organic revenue for Shopify stores across five layers: technical SEO (canonicals, duplicate URLs, faceted navigation, Core Web Vitals, robots.txt.liquid on Plus), on-page SEO (collection and product pages, schema, internal links), content (buyer's guides, comparisons, topic clusters), authority (digital PR and link building) and, since 2025, AI search and AI shopping visibility in Google AI Overviews, ChatGPT and Perplexity.

What makes it *Shopify* SEO is the platform. Every product is reachable at /products/x and at /collections/any/products/x. Tag pages, ?variant= URLs and filter apps such as Search & Discovery or Boost multiply near-duplicates. Non-Plus plans have limited robots.txt control. A generalist SEO agency knows the theory. A Shopify SEO agency knows the Liquid fix.

How we chose these agencies

• Shopify depth: Partner tier, Liquid and theme work done in-house, Plus, Markets and Hydrogen experience.
• Technical fluency: a clear position on duplicate URLs, collection pages, faceted navigation and app bloat.
• Full stack: content, digital PR, Google Shopping feeds and AI search, not just one of them.
• Revenue reporting: non-branded organic revenue as the KPI, not rankings or traffic alone.
• Commercial clarity: published pricing, contract terms and named deliverables.

We didn't accept paid placements, and we didn't rank on self-reported lift percentages. Pricing marked as from Skailama comes from Skailama's April 2026 roundup; all other prices are as published by the agency.

The 11 best Shopify SEO agencies (2026)

1. Conversion: Shopify-only SEO with in-house Liquid developers

Conversion. We wrote this guide, so weigh this entry accordingly. Conversion is a San Francisco based Shopify SEO agency and Shopify Plus Partner. Theme-level fixes, collection-page content, schema, Merchant Center feeds, digital PR and AI search all sit with one team, judged on non-branded organic revenue. Retainers start at $3,000/month and run month-to-month after the first 90 days, with a pay-on-results option.

• Best for: Shopify and Shopify Plus brands that want technical, content, links and AI search under one roof.

2. Netalico: Shopify Plus Premier Partner where the build team does the SEO

Netalico. Netalico treats SEO as a development problem: the same team that builds Shopify stores audits and ships the fixes. It publishes its pricing, retainers of $2,700 to $10,000/month (about $4,500 on average), and targets brands doing $2M to $50M GMV, with an Americas-based team and no subcontracting.

4. Coalition Technologies: High-volume Shopify SEO with a published case-study library

Coalition Technologies. Coalition is a Shopify Plus Partner with a large library of published ecommerce case studies and a named team. Pricing is based on monthly work-order volume rather than a fixed retainer.

• Best for: Brands that want a big agency with a long track record and lots of comparable case studies.
• Watch out for: Volume-based pricing makes quotes hard to compare. Ask for the deliverables included at your budget.

5. SeoProfy: Forecast-first Shopify SEO with transparent starting prices

• Best for: Smaller and mid-sized stores that want no lock-in.
• Watch out for: Not Shopify-only. Confirm Shopify theme and Liquid experience on your account team.

9. Inflow: Ecommerce-only SEO and digital marketing agency

Inflow. Inflow works only with ecommerce brands, across platforms including Shopify. Skailama's roundup lists a $5,000+/month minimum.

Shero Commerce. Shero is a full-service Shopify agency covering development, SEO, CRO and retention under one roof.

• Best for: Brands that want one agency for build, SEO and CRO.
• Watch out for: Full-service agencies can spread thin. Ask how many dedicated SEO specialists will work on your store.

How much does a Shopify SEO agency cost?

To check whether a retainer pays for itself, divide the monthly fee by your gross margin. At a 55% margin, a $5,000/month retainer needs about $9,100 of extra monthly organic revenue to break even; at a $90 AOV that is roughly 100 extra non-branded orders a month.

Agency vs freelancer vs in-house vs SEO apps

• SEO apps handle meta tags, image compression, sitemaps and basic schema for $0–$50/month. They can't fix theme-level duplicates or earn links, and stacking them slows the store. See our guide to the best Shopify SEO apps.
• Freelancers are cost-effective for a defined task. Few cover Liquid development, content, PR and AI search at once.
• In-house hires know the business best but cost $90K–$140K a year in the US and still need developer time.
• A Shopify SEO agency brings the full stack, including developers, for less than one senior hire. That's the model our Shopify SEO services follow.

What a good first 90 days looks like

• Days 1–30: collaborator access (not your owner login), a duplicate theme for every change, full crawl, app audit, Search Console and Merchant Center baseline, duplicate-URL and canonical fixes.
• Days 31–60: Core Web Vitals at theme level, Product/Offer/Review schema, internal linking, faceted navigation control, feed fixes. Every Liquid change logged.
• Days 61–90: collection-page rewrites for top commercial categories, first buyer's guides, AI search formatting, and a 90-day review against the baseline.

Red flags when hiring a Shopify SEO agency

• Guarantees #1 rankings or a fixed traffic number.
• Can't explain how they handle /collections/x/products/y duplicates or ?variant= URLs.
• The plan is mostly installing apps.
• Recommends replatforming on the first call.
• Wants your owner login instead of collaborator access, or edits your live theme directly.
• Reports rankings and traffic but not non-branded organic revenue.
• 12-month lock-in with no performance exit.
• No position on AI search, Google Shopping or AI shopping agents.

Questions to ask on the discovery call

1. How do you handle duplicate product URLs from collection paths and filter apps?
2. Who writes the Liquid changes, and how are they logged?
3. What will you deliver in the first 30, 60 and 90 days?
4. What KPI do you report, and how do you separate branded from non-branded revenue?
5. How do you approach collection-page content on a large catalog?
6. What's your approach to AI Overviews, ChatGPT Shopping and Merchant Center?
7. Can I see a Shopify case study with non-branded organic revenue before and after?
8. What are the contract length and notice period, and who owns the content and code?
