Hiring an e-commerce SEO agency is an unusually hard purchase. You’re buying something you can’t inspect, from people who all use the same vocabulary, on a timeline where you won’t know whether it worked for six months. Meanwhile the invoices start in month one.
This guide is about making that decision with evidence instead of vibes: what agencies actually do, what they cost, the proof to ask for, the questions that separate the competent from the plausible, and the cases where you’re better off keeping the work in-house.
It’s worth knowing what you’d be buying before you shop. The underlying work is covered in what e-commerce SEO is and how it works; if you’re on Shopify, the platform-specific steps and costs show how much of this you could do yourself in a month of evenings.
The Bottom Line
- Ahrefs’ survey of 439 SEO providers found agencies averaging $3,209 a month, consultants $3,250, and freelancers $1,348.63 (Ahrefs). Quotes far below that range usually mean templated work.
- Ask for one thing above all: a real client report from the last quarter, showing revenue or orders, not just rankings.
- Platform experience is not optional. An agency that has never worked in your platform will spend your first two months learning it.
- Walk away from guaranteed rankings, undisclosed link sources, and any contract where you don’t own the accounts.
- If your category has thin search demand or your own site is still a mess, no agency can fix that. Spend the money on the store first.

What an e-commerce SEO agency actually does
Strip away the packaging and the work falls into five buckets: a technical audit and fixes, keyword and category mapping, on-page optimization across product and collection pages, content production, and link acquisition. Reporting wraps around all of it.
The split between those buckets is where agencies differ most, and where mismatches happen. Some are technical shops that will fix your crawl problems brilliantly and write nothing. Some are content houses that will publish twelve articles a month and never touch your faceted navigation. Some are mostly link builders. None of these is wrong, but if your store’s problem is duplicate collection URLs and you hire a content house, you’ll pay for twelve months of posts that can’t rank.
So before you talk to anyone, work out which bucket your bottleneck sits in. A crawl of your own site and a look at Search Console will usually tell you within an afternoon.
What an e-commerce SEO agency costs
The clearest benchmark available comes from Ahrefs’ survey of 439 SEO service providers worldwide: an overall average retainer of $2,917 a month, with agencies at $3,209, consultants at $3,250, and freelancers at $1,348.63, and an average hourly rate of $111 (Ahrefs).
| Engagement type | Typical range | Best for |
|---|---|---|
| One-off technical audit | $500–$2,500 | Diagnosing why a store isn’t ranking before committing to anything |
| Freelancer retainer | ~$1,350/month average | A specific, well-defined gap: technical fixes, or content, not both |
| Agency retainer | ~$3,200/month average | A store with real revenue and several workstreams running at once |
| Project work | $2,500–$30,000 | Migrations, replatforming, a full catalog overhaul |
E-commerce-focused agencies publish retainers from roughly $2,500 up to $25,000 a month, with the upper end aimed at brands doing serious volume. Two practical points about the bottom of the market: a $300-a-month retainer buys a few hours of someone’s time, which cannot cover strategy, execution, and reporting, so something in that package is automated or imaginary. And a cheap engagement that includes link building is the most likely to damage you, because cheap links come from somewhere.
Start with a paid audit if you can. A few hundred dollars for a diagnosis tells you what you need before you commit to a year of retainers, and it doubles as an audition.
Agency, freelancer, or keep it in-house?
The honest answer depends on three things: your revenue, your bottleneck, and how much of your own time is available.
Keep it in-house when your store is small, your category is local, and the obvious work is undone. Nobody knows your products, your customers, or your delivery radius like you do, and the first round of category copy and product descriptions is more about product knowledge than SEO skill.
Hire a freelancer when you have one clearly defined gap. A technical specialist for a migration. A writer who understands your trade. Scope it tightly and you get senior attention at half the cost of an agency.
Hire an agency when several workstreams need to run at once, when there’s enough revenue that a few percentage points of organic growth pays the retainer several times over, or when a replatform is coming and the cost of getting it wrong exceeds the fee.
Before committing either way, check that the tooling isn’t the cheaper answer; the Shopify SEO tools worth installing covers what $20 a month of software automates.
How to vet an e-commerce SEO agency
Vetting is mostly about asking for evidence rather than opinions.
Ask for a client report from last quarter. Not a case study page, an actual report. Redacted is fine. You’re looking for whether they report in orders and revenue or only in rankings and “impressions up 300%.”
Ask for two references in e-commerce, ideally one whose engagement ended. The ex-client conversation is the most informative one you’ll have.
Check platform experience specifically. Shopify, WooCommerce, BigCommerce, and Magento have different constraints, and an agency that will make on-page changes needs to know yours. Ask what they’d change about your faceted navigation. A real answer arrives in about thirty seconds; a vague one tells you everything.
Find out who does the work. The person in the pitch is frequently not the person on your account. Ask who it will be, how many other clients they carry, and whether anything is subcontracted.
Ask how they’d spend the first 90 days on your store, specifically. A generic answer means they haven’t looked. A good one will name something real about your site.
Questions to ask an SEO agency before you sign
- What does success look like at month 3, month 6, and month 12, in my units? Orders and revenue, not rankings.
- How do you build links, and can I see the last ten you placed? Vagueness here is the single biggest warning sign in the industry. It helps to know roughly how the legitimate methods work before you ask. Overviews of how to build backlinks for e-commerce will tell you enough to judge whether the answer you get is plausible.
- What do you need from me each month? Honest agencies say “approvals, product knowledge, and developer access.” Underperformance is often really a client who never replied.
- What’s the contract term, and how do I exit? Six months is a fair minimum for SEO. Twelve with no exit clause is not.
- Who owns the accounts and the content? Your Search Console, analytics, and anything written for you should stay yours when the relationship ends.
- What happens if results don’t come? The answer should describe a diagnostic process, not a guarantee.
Red flags in an SEO agency pitch
- Guaranteed rankings or guaranteed positions. Nobody controls Google’s results. Anyone promising otherwise is either lying or planning something risky.
- Secret link building. If they won’t name sources or show placements, assume you’re buying links from a network that can get your store penalized.
- No questions about your business. An agency that pitches before asking what you sell, where you deliver, and what your margins look like is selling a template.
- Reporting that only goes up. Real reports contain things that didn’t work. A dashboard where every arrow is green is a marketing artifact.
- Pressure to sign this week. Discounts that expire are a sales tactic, not a pricing structure.
- One person’s name on every case study. Usually the founder, usually no longer doing client work.
What a good agency engagement looks like in the first 90 days
Month one should be diagnosis and quick wins: a full crawl, Search Console cleaned up, broken links and redirect chains fixed, a keyword-to-page map you can actually read, and a prioritized list with reasoning.
Month two should be execution on the highest-value pages, usually collection and category pages, since those match how buyers search and are routinely the weakest pages on a store.
Month three should bring the first measurable movement, typically on pages that were already ranking on page two, plus whatever content or link work was agreed. If by day 90 you have no deliverable you can point to, no page you can see improved, and no report in your own units, that’s not a slow start. That’s the shape of the whole engagement.
When to skip an agency entirely
Three situations where the money is better spent elsewhere.
Your category barely has search demand. If the terms you’d target get a few dozen searches a month in your delivery area, there’s no amount of optimization that creates demand. Put the budget into the channels where your customers already are, or into the operation itself. For a lot of food and floral businesses, the retainer money does more good spent on getting wholesale bakery delivery right or sharpening the corporate catering service that already brings in repeat accounts.
Your store isn’t ready. Thin product pages, no reviews, slow mobile load, and no clear delivery information will cap any SEO campaign. Fix the store, then market it.
You haven’t done the free work yet. Most small stores have several months of unpaid improvements available: collection names, real category copy, original product descriptions, compressed images, alt text. Do that first. You’ll also understand far more about what an agency is proposing when you’ve done some of it yourself, and you may find you don’t need one.
Frequently asked questions
How much should a small store pay for e-commerce SEO?
Below roughly $20,000 a month in revenue, often nothing: do the foundational work yourself. Above that, a scoped freelancer around $1,000 to $1,500 a month is usually better value than an entry-level agency package, based on the provider averages in Ahrefs’ survey (Ahrefs).
How long should I give an agency before judging results?
Six months for traffic movement on new work, but judge the process at 90 days. Deliverables, communication, and reporting quality are all visible by then, and they predict the outcome better than early rankings do.
What’s the difference between an SEO agency and an e-commerce SEO agency?
Catalog scale and the problems that come with it: faceted navigation, duplicate variant URLs, out-of-stock handling, product schema, and category architecture. A generalist can run a solid campaign for a service business and still be out of their depth on a store with 2,000 SKUs.
Should I hire an agency that also runs my ads?
It can work well, because organic and paid data inform each other. The risk is that paid results arrive faster and absorb the attention and the budget. If you combine them, insist on separate reporting for each.
