Ecommerce SEO Pricing: What It Costs
Agency ecommerce SEO runs $1,500 to $6,000 a month for most single-market stores. What moves that number, and what a quote should actually include.
Ecommerce SEO for a single-market store typically runs $1,500 to $6,000 a month with an agency, or $60,000 to $150,000 a year for one in-house specialist. Price scales with catalog size and technical debt, not a fixed package tier — a 200-SKU store on a clean platform pays far less than a 20,000-SKU store on a legacy one.
That range sits inside the larger ecommerce SEO picture: architecture, schema, keyword research and platform choice all move the number before an agency ever writes a quote.
What does ecommerce SEO cost per month?
Most agencies sell ecommerce SEO as a monthly retainer, priced by scope rather than by store category. A small store with a clean platform and a modest catalog sits at the low end; a large or messy catalog pushes hours, and therefore price, up.
| Store profile | Typical monthly range | What drives the hours |
|---|---|---|
| Under 500 SKUs, one platform | $1,500–$3,000 | Category and product page fixes, a handful of new pages a month |
| 500–5,000 SKUs, some legacy pages | $3,000–$6,000 | Faceted navigation, schema rollout, larger content backlog |
| 5,000+ SKUs or multiple storefronts | $6,000–$15,000+ | Templated fixes at scale, migration risk, ongoing technical debt |
Project work is quoted separately from a retainer. A platform migration, a one-time technical audit, or a full schema markup rollout across a catalog is usually a fixed-fee project with its own start and end date, not a monthly line item.
Two things push a quote toward the top of its range regardless of store size: multiple storefronts on one domain, and a backlog of redirect and duplicate-content problems from a past migration. Both add hours before any new work starts, because the agency has to stabilize the foundation first.
Why does ecommerce SEO cost more than SEO for a brochure site?
Because a store has more surface area. A five-page company website has five templates to get right. A store with category pages, filters, product pages and a search results page has at minimum four templates, each of which repeats across thousands of URLs — so one template mistake becomes a thousand identical mistakes.
Is hiring in-house cheaper than an agency?
Rarely, once you count fully loaded cost. A single ecommerce SEO specialist in the United States runs $60,000 to $150,000 a year in salary depending on seniority, before payroll taxes, benefits, or the tools they need — a crawler, a rank tracker, a keyword research subscription — which commonly add several hundred dollars a month.
An in-house hire makes more sense once a store is large enough to need full-time attention: a catalog in the tens of thousands of SKUs, frequent platform changes, or an in-house content team the specialist can direct. Below that scale, a fraction of an agency's time usually covers the same ground for less. Because organic traffic that does not convert is money left on the table, it is worth pricing SEO alongside CRO and SEO run together rather than as two unrelated invoices.
What should an ecommerce SEO quote actually include?
A quote worth comparing states its scope in writing, not just its price. Ask for these five things before you sign anything.
A list of templates in scope
Category, product, search-results and blog templates, named individually — not "the website" as one line.
A content allowance
How many new or rewritten pages per month, and whether product copy is included — see how we approach product description SEO.
A technical baseline
A crawl of the current site, so both sides agree on the starting problems before billing starts.
A reporting cadence
What gets reported, how often, and in which channels — rankings, organic sessions, or revenue from organic.
An exit clause
What happens to the work — documentation, access, historical data — if either side ends the engagement.
Does ecommerce SEO pricing ever pay for itself?
Usually, but on a longer timeline than a paid channel. A realistic worked example: a mid-sized store paying $4,000 a month for a year, with organic sessions and organic revenue tracked from day one against a baseline set before work started, is the kind of case a store owner can hold an agency to. We describe how one such result looks in practice — an anonymised, clearly hypothetical example rather than a real client, because that is what we have room to show at this stage.
Judge the price against that timeline, not against a single month's ad spend. A $4,000 monthly retainer that replaces a channel costing $8,000 a month within a year is a good trade even though month one looks like pure cost.
Set the baseline before the invoice starts, not after. Record current organic sessions, organic revenue and ranking positions for a defined set of pages in the week before work begins, then compare against that same set monthly. Without a written baseline, any later claim of improvement is a story rather than a measurement, and neither side can settle a disagreement about whether the price was worth it.
Questions people also ask
Why do ecommerce SEO quotes vary so much between agencies?
Because scope varies. A quote for 50 hours a month of technical work, content and link building is not comparable to a quote for a monthly report and a call, even if both are labelled the same package. Ask each agency to price the identical scope before comparing numbers.
Is a flat monthly retainer better than project pricing for a store?
A retainer suits ongoing work: new categories, seasonal pages, content and fixes as the catalog changes. A one-off project — a migration, a technical audit, a schema rollout — is better priced as a project, because it has a defined end.
Does store size change the price more than industry does?
Usually, yes. Catalog size, platform and how much technical debt exists drive scope more directly than which industry the store sells into. A 300-SKU apparel store and a 300-SKU electronics store cost about the same to work on; a 300-SKU store and a 30,000-SKU store on the same platform do not.
Should CRO be priced together with SEO for a store?
It is worth pricing as one programme even if it is billed separately, because traffic that does not convert is a wasted line item. See how we think about running both together.
