Most ecommerce brands that hire an SEO agency end up with a content calendar. A year later, organic revenue looks the same as it did at signing, because blog posts were never where the money was. On a Shopify catalog doing $1M to $50M, non-branded organic revenue comes from collection pages, PDPs, and comparison pages that intercept people already shopping. Everything else is support.
That is the lens we used to rank the best SEO agencies for ecommerce brands in 2026. The eight below, in order, are 95 Projects, Inflow, Single Grain, NoGood, Siege Media, Foundation Marketing, Common Thread Collective, and Pilothouse. Pricing across the list runs from roughly $3,500 per month at the low end to $50,000 or more per month at the top, based on published and third-party-reported figures. Only two of the eight publish their rates at all.
Rankings are based on each agency’s own website and service pages, Clutch profiles, and third-party reporting, reviewed as of September 19, 2026.
95 Projects is a search marketing agency built specifically for brands in the $1M to $50M revenue range that want SEO, Google PPC, and GEO running as one integrated practice instead of three siloed line items on a media plan. The agency is founder-led, staffs senior strategists with capped account loads (not pod-based execution), and reports against attributable revenue.
The working model is straightforward. Senior strategists carry capped account loads instead of being spread across a pod, and the founder stays on the account. SEO sits at the center. Google Search and Shopping campaigns are used to find which queries actually convert for your catalog, and those queries then set the SEO roadmap for collection pages, PDPs and comparison content.
$5,000 to $20,000 per month, published on the site. Scope is set by catalog size, technical debt, and whether Google PPC and GEO are included alongside SEO.
Inflow is an ecommerce-focused agency listed in Tampa on Clutch, which shows it was founded in 2007. Its selling point is structural: clients work directly with senior specialists, without an account manager sitting between the brand and the person doing the work.
Services cover SEO, PPC including Google Shopping and Amazon Advertising, paid social and CRO. That makes it one of the few options here that treats conversion rate work as part of the same engagement. It holds Google Premier Partner, Meta Business Partner, Microsoft Advertising Partner and Buy With Prime Agency Partner status.
Clutch shows 4.9 across 12 reviews. Reviewed clients include KEH, Gaia, Aviator Gear and Shore Excursions Group.
$1,000+ minimum project, $150 to $199 per hour. A long-time client reported roughly $24,000 to $80,000 per year, and third-party reviews cite monthly pricing from about $3,500 to $4,000.
Single Grain, led by Eric Siu, sells an integrated offer across SEO, PPC, content and GEO, which it frames as “search everywhere optimization.” That framing is the right one for 2026, since discovery is now split across Google, AI assistants and marketplaces. The agency is multi-vertical rather than ecommerce-native, and its named clients skew toward large tech brands: Amazon, Uber, Salesforce and Nextiva.
$10,000 minimum, with engagements running $10,000 to $50,000 or more per month (checked July 2026).
NoGood is a New York growth agency founded in 2016 that builds creative-led growth squads. It has been early and loud on AI search. CEO Mostafa ElBermawy publicly coined “AEO” at SXSW in 2023, and in January 2025 the agency launched its Goodie AEO platform, which tracks visibility across 11 or more AI engines, including Amazon Rufus.
For a consumer brand, Rufus coverage is the interesting part. Marketplace assistants now sit between shoppers and products in a way classic rank tracking never captured.
Goodie case studies report Dermalogica at +127% AI conversions and SteelSeries at 3.2x AI search conversions in six months.
Not published. Industry-reported at $15,000 to $25,000 per month, and directories list a $50,000+ minimum project.
Siege Media, founded in Austin in 2012, built its reputation on content-led SEO: editorial, design and interactive assets designed to earn links rather than beg for them. It now positions itself as a full-service GEO agency, offering SEO and GEO consulting, content, affiliate partnerships, Reddit marketing and digital PR.
Its GEO measurement is more specific than most, covering LLM share of voice, citations per asset, AI-referral traffic and branded search lift. The company has made the Inc. 5000 six times.
$5,000 minimum and $100 to $149 per hour, with a most common project size of $50,000 to $199,999. Retainers typically run $8,000 to $20,000 per month (June 2026).
Foundation Marketing is based in Halifax, Nova Scotia. Ross Simmonds founded it roughly twelve years ago, and it has around 55 employees. It is a content creation and distribution agency built for B2B brands, and its distribution discipline is genuinely better than most content shops.
It now positions itself as an AI visibility and GEO agency. It is a Certified Reddit Partner, with a Reddit case study featuring Bitly and Paychex, which matters given how heavily assistants lean on Reddit threads when answering product questions.
Not published. Clutch reviews reference an execution roadmap near $20,500 followed by quarterly retainers around $30,000. A third-party comparison says engagements start around $10,000 per month equivalent.
Common Thread Collective, based in Costa Mesa, is a DTC growth agency built around forecasting, contribution-margin reporting and incrementality testing. Its Prophit Engineer model puts one person in charge of the forecast, the media and the creative, which produces the cleanest financial reporting of any agency on this list. If your problem is that nobody can tell you what a marketing dollar is actually returning, CTC is built for that problem.
It is not an SEO shop. As of September 2026, its service menu lists growth strategy, Meta ad buying, Google ad buying, ad creative and incrementality, with no dedicated SEO or GEO service. It is included here as an honest option for brands whose organic work will live with a separate partner.
Published. 7-figure brands pay $5,000 to $15,000 per month, and 8-figure brands $15,000 to $50,000 per month. PE Lite is $1,500 onboarding plus $500 per month, month to month.
Pilothouse, founded in Victoria, BC in 2019, is a full-funnel DTC performance agency. It has in-house media buyers across Meta, Google, TikTok, Amazon and YouTube, plus creative teams handling UGC, ad creative, and email and SMS design. Clients include Benchmade, Hestan Culinary, Big Blanket Co, Chamberlain Coffee and General Mills. It is a strong paid partner for consumer brands with real creative volume needs.
Third-party reviewers say AI search is not currently a focus and that SEO and content are not core to the offer. It belongs on this list as a paid-first option rather than an organic one.
Not published. A third-party estimate puts it at $10,000 to $25,000+ per month as a base retainer, or a hybrid structure with a percentage of revenue or ad spend.
Only 95 Projects and Common Thread Collective publish rates. For everyone else you are negotiating against a number you cannot see. Ask for the retainer, the minimum term, and what happens to scope if you pause.
The useful question is not whether $10,000 a month is expensive. It is how many incremental orders that retainer has to produce before it clears contribution margin. Here is an illustrative model. The numbers below are examples only, not benchmarks, and you should rerun them with your own Shopify and GA4 data.
Illustrative brand: $6M in annual revenue, on Shopify, with Google Shopping and Meta running.
At $38.70 contribution per order, a $10,000 monthly retainer needs about 259 incremental organic orders per month to break even on the fee alone. That is roughly $22,000 in incremental monthly organic revenue at an $85 AOV. A $5,000 retainer needs about 130 orders, or roughly $11,000 in incremental monthly revenue.
Two things change that math in organic’s favor. First, an organic order carries no media cost, so the full $38.70 flows to contribution instead of $38.70 minus CAC. On the illustrative numbers, a paid new customer at $62 CAC is underwater on the first order and only clears payback once the 32% repeat rate does its work. An organic new customer clears on order one.
Second, organic revenue growth lifts blended MER without touching ad spend. That is usually the fastest way to improve the number your board is actually watching.
Set the target this way: agree with the agency on a monthly incremental non-branded organic revenue number that makes the retainer clear contribution margin inside your payback window. Then report against that number in GA4 and Shopify rather than against keyword counts.
The click economics of search moved, and informational content took the hit first.
Pew Research Center published browsing data on July 22, 2025, covering 900 US adults and 68,879 Google searches from March 2025:
Search Engine Journal reported on April 27, 2026, on a randomized field experiment by Agarwal and Sen of ISB and Carnegie Mellon. It is a working paper that has not been peer reviewed. It found AI Overviews cut organic clicks by 38% on queries where they appeared, with zero-click sessions rising from 54% to 72%.
For a catalog business the practical read is narrow. The pages most exposed are top-of-funnel blog posts answering questions a model can summarize in two sentences. The pages least exposed are the ones attached to a transaction: collection and category pages, PDPs, Shopping and free listings, and comparison or best-for pages. On those, the shopper needs to see price, variants, reviews and availability before deciding, so they still click, because the click is the only way to complete the task.
GEO is the second half of the same job. When a shopper asks an assistant which product to buy, the answer is assembled from sources the model can parse and trust:
The pages you optimize for commercial-intent rankings are the same pages that get cited. That is why running SEO, Shopping and GEO on separate teams tends to produce three roadmaps that never agree.
Ask every agency on your shortlist to show the first 90 days in specifics. Five things tell you whether they have run a catalog before.
Filtered URL combinations on a large Shopify or Magento catalog can generate tens of thousands of low-value pages that soak up crawl budget and split signals. A real plan names which facets get indexed, which get canonicalized, which get blocked, and what happens to the parameters already sitting in the index. If the audit deck stops at title tags and broken links, it was run by a tool, not a person.
Collection pages are where non-branded commercial intent lands. The plan should cover four things:
Feed quality, product schema accuracy and free listings eligibility sit at the intersection of SEO and paid. Some agencies cannot speak to GTIN coverage, attribute completeness or disapprovals in the feed. Those agencies will leave free listings revenue on the table and give you an SEO plan that ignores half the SERP.
Branded organic traffic tracks your paid and PR spend, not your SEO work. Ask to see a sample report that separates branded from non-branded, ties non-branded sessions to revenue in GA4 and Shopify, and shows organic new-customer orders rather than total sessions.
If the technical work and collection builds are scheduled for October, your Q4 is the test environment. A plan that knows BFCM exists front-loads infrastructure work in Q2 and Q3 and freezes risky changes ahead of peak. It also builds gifting and seasonal collections early enough to mature before traffic arrives.
The structure is predictable, which helps, and constrained, which does not. Collection URL handling and the /products/ and /collections/ path duplication need canonical discipline. Filtered collection URLs need an indexation rule, and theme choice directly affects Core Web Vitals once you stack apps.
Most of the technical ceiling on Shopify comes from app bloat and unoptimized imagery, not from the platform itself. The upside is that collection page templates can be improved once and applied across hundreds of pages.
BigCommerce gives you more flexible URL and faceting control than Shopify, with more room to get it wrong. Watch for duplicate product URLs across categories, automatically generated thin brand pages, and pagination handling on deep catalogs. Multi-storefront setups need a clear canonical and hreflang plan before anyone writes content.
Magento offers the most control and carries the most technical debt. Layered navigation generates parameter URLs at volume, and indexing and caching configuration directly affects crawlability and speed. Extensions commonly conflict in ways that surface as intermittent 500s or slow time to first byte.
Magento-to-Shopify migrations are the most common project we see in this segment, and they are where most organic revenue gets destroyed. Before cutover, insist on three things:
SEO works best as the compounding center of a three-channel system. Here are the integrated services 95 Projects runs for ecommerce brands:

Across the agencies reviewed here, entry points run from about $3,500 per month up to a $10,000 monthly floor. Common retainers fall between $5,000 and $25,000 per month, and enterprise engagements reach $50,000 or more. 95 Projects publishes $5,000 to $20,000 per month. Common Thread Collective publishes $5,000 to $15,000 for 7-figure brands and $15,000 to $50,000 for 8-figure brands. Most others quote privately.
It depends on where you start. Technical fixes on faceted navigation, canonicals and page speed can move revenue inside a quarter because you are recovering demand you already had. New collection and comparison pages targeting non-branded commercial queries typically take longer to mature.
In our own work, a luxury fashion catalog moved from position 18 to #1 on category queries in 90 days, and a hydration brand saw attributable AI search revenue in the first month. Fast results are possible when the technical base is sound and the category is winnable.
Run both and let Shopping inform SEO. Paid search tells you within weeks which queries actually convert for your catalog, and those queries are the correct SEO priorities. The organic version of the same query eventually produces orders without the media cost, which is what improves MER. Treating them as competing budgets is how brands end up with an SEO roadmap built on search volume instead of revenue.
No. Any agency that guarantees keyword rankings does not understand how Google works. We guarantee the methodology, the content production rate, the technical SEO discipline, and consistent improvement against business KPIs over the course of an engagement.
It means every account is owned by a senior strategist (5+ years of SEO experience at the strategy level) with a capped portfolio of 4 to 6 accounts. We do not run pod-based execution where junior writers and account managers handle the day-to-day under senior supervision. The senior strategist owns the content roadmap, the technical SEO, and the revenue reporting.
Engagements typically run between $5,000 and $20,000 per month depending on the scope, channel mix, and content production volume. We work with ecommerce brands in the $1M to $50M annual revenue range and scope engagements to fit the size of the business.
