The top SEO agency for Shopify stores in 2026 is QCK, because Shopify is its focus and it pairs Shopify SEO and AI search with A/B tested conversion work, publishing every result: 197 A/B tests with an 86.8% win rate and $250M+ in organic revenue driven for clients. After QCK, the strongest Shopify SEO options are Charle, 1Digital Agency, Eastside Co, Swanky and Optimising, each with a Shopify partner credential shown on Shopify's Partner Directory or its own site.
Disclosure: QCK wrote this list. We put ourselves first, and the rest of the list is ranked by how well each agency fits Shopify brands that want organic growth. Every other agency is described only from its own website or its Shopify Partner Directory listing, checked in October 2026.
This guide is only for Shopify and Shopify Plus merchants. You'll get the Shopify-specific SEO issues an agency should handle, an evaluation table with questions and red flags, the ranked list with each agency's Shopify partner status, and a checklist for the first 60 days. If you sell on several platforms, see our cross-platform list of the top SEO agencies for e-commerce instead.
What a Shopify SEO agency should handle
Shopify takes care of a lot of SEO plumbing, which is exactly why generic SEO agencies struggle with it. The basics are automatic, so the gains come from knowing where the platform's defaults stop. Shopify's help center documents the first four rows below.
| Shopify behavior | How it works on Shopify | What your agency should do |
|---|---|---|
| Sitemap | Every store automatically generates a sitemap.xml that updates when you add products, collections, pages or posts | Check what's in it, and keep thin or duplicate pages out of the index |
| Robots.txt | Editable through a robots.txt.liquid theme template, an unsupported customization Shopify warns can cause "loss of all traffic" if misused | Change it only with a clear reason, such as filter URLs or AI crawler access, and test every change |
| H1 headings | Generated from the title you enter for a product, collection, page or post | Write product and collection titles for both shoppers and search |
| Title tags and meta descriptions | Editable for products, collections, pages, posts and the homepage; blank titles default to the content title plus shop name | Write unique titles and descriptions at scale, starting with top revenue pages |
| Themes and apps | Your theme and installed apps control page markup and scripts | Audit speed, structured data and duplicate markup added by apps |
You can check several of these yourself in minutes. Run your sitemap through the sitemap checker, test your robots.txt with the robots.txt tester and check product schema with the schema validator. For a deeper walk-through, read our guide to improving SEO on Shopify.
How to choose a Shopify SEO agency
Start with Google's advice on hiring an SEO: ask for past work and success stories, ask what results to expect and when, and walk away from guarantees. Google says "No one can guarantee a #1 ranking on Google," and warns against SEOs that claim a special relationship with Google or won't explain what they plan to do. Then add the Shopify-specific criteria below.
| Criterion | Question to ask | Red flag |
|---|---|---|
| Shopify depth | What have you changed in Liquid themes, metafields and robots.txt.liquid for other stores? | Can't name a Shopify-specific fix |
| Partner status | Are you listed in Shopify's Partner Directory, and at what tier? | Claims a tier the directory doesn't show |
| Collection pages | How do you decide which collections and filters should rank? | A plan built only on blog posts |
| Apps and speed | How do you audit app scripts and theme weight? | Suggests installing more SEO apps as the fix |
| AI search | How do you track if our products are named in ChatGPT, Google AI Overviews and Perplexity? | No defined prompts or tracking method |
| Conversion | Do you A/B test product and collection pages, and can we see the results? | Only reports rankings and sessions |
| Migrations | How do you protect rankings in a theme change or replatform to Shopify? | No redirect map before launch |
A Shopify Partner listing tells you an agency has a track record on the platform. Shopify's directory says partners are tiered on factors including "history of experience and proven success on Shopify." It doesn't tell you how deep the agency's SEO practice is, so ask the SEO questions regardless of tier.

Top SEO agencies for Shopify stores in 2026
Here's the ranked list. Partner status is shown only where Shopify's Partner Directory or the agency's own site states it. We didn't include ratings, pricing, awards or client results for other agencies because we can't verify them independently.

1. QCK: best overall for Shopify SEO, AI search and CRO
QCK is an SEO, AI search and conversion rate optimization agency for e-commerce brands, with Shopify as its focus. We rank first because no other agency here publishes both its organic results and a complete record of its A/B tests on store pages, so you can check the work before you hire us.
Conversion data from real stores. QCK has run 197 A/B tests across 26 e-commerce stores. 171 won, an 86.8% win rate, with an average lift of 12.8% per test and $1,214,283 in added revenue. The win rate held up across every store page type we tested:
View the data
| Value | |
|---|---|
| FAQ sections (19 tests) | 100% |
| Homepage (51 tests) | 94.1% |
| Product pages (62 tests) | 87.1% |
| Sitewide (54 tests) | 85.2% |
| Collections (21 tests) | 81% |
Source: QCK A/B test results, 197 tests, qck.co/ab-test-results
That matters for SEO because the pages that rank are the pages that sell. When we rewrite a collection page to rank, we add the elements that tested well, such as an FAQ accordion (19 wins in 19 tests on homepages and collections) or review stars placed near the product title (8 wins in 9 tests). Every test, wins and losses, is on our A/B test results page.
Organic growth you can verify. Our case studies show each brand's starting traffic, ending traffic and time period, based on third-party traffic estimates (Ahrefs and DataForSEO). Some examples:
View the data
| Value | |
|---|---|
| Koia, health (3 months) | 350% |
| SA Fishing, outdoors (5 months) | 278% |
| Nicks Boots, apparel (21 months) | 165% |
| Little Trouble, baby and kids (11 months) | 156% |
| Stork Baby Gifts, baby and kids (10 months) | 89% |
| Saalt, health (4 months) | 69% |
Source: QCK case studies, cs.qck.co
Scale and team. QCK has served 228+ clients, built 7,960 live pages for them and driven $250M+ in organic revenue. QCK ranked #181 on the 2026 Inc. 5000, and its case study library tracks 38,707 AI citations across 16 featured client brands. The team is in-house and QCK was founded by a CPA, so reporting starts with revenue, not rankings. Because SEO, AI search, CRO and Shopify web design sit in one team, a fix found in an audit gets built in your theme instead of handed back to you.
Best for: Shopify and Shopify Plus brands that want rankings, AI visibility and conversion lift from one team, with proof published in advance.

Shopify SEO agency vs Shopify build agency
Many top Shopify agencies are build partners first. That's a strength when you need a new theme or a migration, but it changes what you get from the SEO line on the proposal.
| Need | SEO-first agency | Build-first Shopify agency |
|---|---|---|
| Grow organic revenue on your current theme | Core focus | Usually a secondary service |
| New theme or Shopify Plus migration | Ranking protection and redirect plan | Core focus |
| AI search visibility | Measured and worked on monthly | Varies by agency |
| A/B testing product and collection pages | Varies; ask for a test record | Varies; ask for a test record |
If you hire a build partner for a redesign, bring your SEO agency into the project before the theme is designed, not after launch. Check redirects on launch day with the redirect checker.
Your first 60 days with a Shopify SEO agency
A strong agency gives you a clear plan in the first two months. Use this sequence to check progress.
- Week 1: access. Grant collaborator access in Shopify and read access to Search Console and GA4. Record organic revenue, sessions by template (product, collection, homepage, blog) and a baseline AI visibility check.
- Weeks 1 to 3: theme and app audit. Speed, duplicate URLs, structured data, apps injecting scripts or markup, and what's in your sitemap.
- Weeks 2 to 4: collection pages. Map one primary keyword to each important collection, rewrite titles and intro copy, and add FAQ content where shoppers have questions.
- Weeks 3 to 6: product pages. Unique titles and descriptions for top sellers, review and product schema, and clear product facts AI tools can quote. Our title tag checker helps you review them.
- Weeks 5 to 8: test and report. A/B test the changed templates and get a first report that leads with revenue, not rankings.
