White-label SEO pricing: how much to mark it up, and how the margins actually work

Somewhere between 50% and 100% on top of the wholesale rate is the honest short answer, with the right figure inside that range depending on how much your agency adds around the work. I deliver white-label SEO for agencies, so I sit on the wholesale side of this arrangement, and I'd rather my agency partners price their resale properly than squeeze themselves into an unprofitable retainer and quietly resent the whole thing six months in. A well-priced arrangement lasts; an under-priced one churns.

This post covers the whole money side of the arrangement: the engagement models you can buy white-label SEO in, how much to actually add on top, what that gap has to pay for, and the places where a margin that looked healthy on paper quietly stops being one. Published pricing guides will give you wholesale package figures, and they vary enormously by market and by what's actually included, so rather than repeat someone else's price list I've focused on the structures. The structure of the arrangement determines your margin far more than the headline rate does.

Markup and margin are not the same number

This trips up more agency owners than anything else in resale pricing, so it's worth thirty seconds. Markup is the percentage you add to your cost. Margin is the percentage of the final price you keep. A 100% markup gives you a 50% margin, not a 100% one. If your specialist charges £1,000 a month and you bill the client £1,500, that's a 50% markup but only a 33% margin, and it's the margin that has to pay for your sales time, your account management, and your risk.

When someone tells you their target is "50%", ask which one they mean. The difference between a 50% markup and a 50% margin on the same wholesale cost is the difference between billing £1,500 and billing £2,000.

The engagement models, compared

White-label SEO gets bought in five broad shapes. Each one suits a different demand pattern, and each one fails in a different way.

Model	How it's billed	Where it suits	Where it goes wrong
Monthly retainer	Fixed fee for an agreed recurring scope	Ongoing SEO across a stable client base	Scope drift eats the margin a month at a time
Per project	Fixed price per audit, migration, or build	Lumpy demand, one-off technical work	Loose briefs push the estimating risk onto you
Day rate	Time billed as used	Overflow capacity, unpredictable workloads	Hard to package into a client-facing price
Per deliverable	Unit price per audit, post, or batch of links	Content and link programmes at volume	Quality falls off a cliff at low unit prices
Tiered packages	Off-the-shelf bundles at wholesale rates	High-volume local SEO resale	Nobody senior touches the cheap tiers

The retainer is the default for a reason. It gives the specialist predictable capacity, it gives the agency a predictable cost to price against, and it maps neatly onto how agencies already bill their own clients. The per-project model is the natural fit for the technical end of the work, audits and migrations especially, and it's how a lot of arrangements start before settling into a retainer. The same logic extends to builds, which I've covered in white-label web development.

The model I'd treat with the most caution is the cheap tiered package. The economics only work for the provider at volume, which means process over judgement, and the brand absorbing the quality risk is yours, not theirs.

Common markup ranges, and where you should sit

Published reseller pricing guides put common markups anywhere from 50% up to 200%, meaning agencies bill between one and a half and three times the wholesale rate. That's a wide band, but it narrows quickly once you're honest about what your agency contributes beyond passing the work along.

Markup	Resulting margin	When it's defensible
25 to 50%	20 to 33%	You're a thin pass-through: forwarding reports, minimal account management. Fragile, and below 25% you're working for free once overheads land
50 to 100%	33 to 50%	The sensible default. You own the client relationship, present the work, translate findings, and handle strategy conversations
100 to 200%	50 to 67%	You add significant value on top: paid media integration, CRO, creative, or a brand strong enough to command premium fees

Worked through on a £1,200 a month wholesale retainer, that's a client price of roughly £1,800 to £2,400 for most agencies. On a one-off £1,500 technical audit, you'd typically bill £2,250 to £3,000, and the presentation of the findings is where you earn that difference. If you can't articulate what the client gets from you that they wouldn't get going direct, your markup has no floor under it, and that's a positioning problem before it's a pricing one.

What the gap has to pay for

The markup isn't profit, it's gross margin, and three costs come out of it before anything reaches you. Client acquisition first, because the client came through your marketing and your sales conversations, and that cost has to be recovered over the life of the retainer. Account management second, which on a typical SEO retainer runs a few hours a month of meetings, translation, and reassurance, every month, whether the specialist needed you that month or not. And risk third, because your brand is on the work, and if it goes wrong you fund the repair of the relationship.

Price those at zero and a 30% markup looks generous. Price them honestly and you'll land somewhere in that 50 to 100% band without needing a guide to tell you.

Where the margin quietly collapses

The arrangements that fail rarely fail on the headline rate. They fail on the edges, and the edges are checkable in advance.

Scope drift is the big one. A retainer scoped as "ongoing SEO" with no definition of what a month contains will grow until it fills whatever the client asks for, and the growth comes out of your margin or the specialist's goodwill, usually both in turn. A proper scope names the deliverables and the review points, and both sides re-price when reality diverges from it.

Unbilled translation time is the quiet one. If the specialist's output arrives needing an hour of account manager rework before a client can see it, that hour is a real cost that never appears on an invoice. Over a year it's the difference between a good margin and a mediocre one. This is why work arriving in your templates and your tone, ready to send, is worth paying more for, a point I made in the how it works post and will keep making.

Extras are the visible one. Setup fees, content billed separately from the retainer that supposedly includes content, tooling charges passed through with a margin on top. None of these are illegitimate on their own, but they belong in the comparison when you're weighing one provider against another, because a lean-looking retainer plus extras often lands above the honest all-in quote it beat.

Cost-plus or value-based billing

Cost-plus, taking the wholesale rate and adding your percentage, is the right model when SEO is a bolt-on to your core service and the client is price-anchored to market rates. It's simple, predictable, and easy to defend in a renewal conversation.

Billing on value, setting the client price by what the outcome is worth and treating the wholesale cost as an input, is better when SEO drives measurable revenue for the client and your agency owns the strategy. An ecommerce client making an extra £20,000 a month from organic doesn't care whether your delivery cost £1,200 or £2,000, and pricing against the wholesale number leaves money on the table.

Most agencies should run cost-plus on retainers and move towards value pricing on project work, where the outcome is concrete and the anchor is weaker. What I'd avoid is mixing the two on the same client, because a retainer priced one way and projects priced the other invites the client to compare the implied rates. Either way, the client-side price shouldn't be derived from the wholesale rate alone. Price the work at what it's worth in your market, at your positioning, to that client, then check the wholesale cost leaves you a margin that pays for your involvement. Agencies that only ever price cost-plus end up cheap where they could have been fairly paid, and thin exactly where the work is hardest. I've covered the positioning side of that conversation in selling SEO you don't deliver in-house.

Keep the wholesale layer invisible, not the involvement

One caution from the delivery side. The markup conversation tempts agencies to keep the specialist as far from the client as possible, in case the client works out the arrangement. In practice the opposite protects your margin better. The agencies I work with who sustain healthy markups are the ones who stay genuinely involved, who understand the work well enough to present it convincingly, and who choose the white-label route over hiring deliberately rather than as a way of disappearing from delivery. Clients pay the premium for an agency that owns the outcome. They resent it when they discover a forwarding service, and how the white-label relationship works day to day is what determines which of those they experience.

White-label SEO pricing FAQs

Is a 100% markup on white-label SEO too much?

No, provided you're doing the work that justifies it. Doubling the wholesale rate gives you a 50% margin, which is a normal gross margin for an agency service once account management and acquisition costs are counted. It becomes too much only when the agency adds nothing beyond an invoice, because sooner or later the client notices.

Is a retainer or per-project pricing better for white-label SEO?

Retainers suit ongoing demand across a stable client base; per-project suits lumpy or technical work like audits and migrations. Plenty of good arrangements start per-project and settle into a retainer once both sides trust the scoping. Projects carry more estimating risk and more intensive presentation work in a short window, so they justify the upper end of your markup range; retainers spread the load and most agencies sit slightly lower on recurring work in exchange for the lifetime value. The wrong answer is a retainer with no defined monthly scope, which drifts until it hurts.

Should I tell clients I use a white-label provider?

You're not obliged to volunteer the mechanics, and most white-label arrangements run under NDA precisely so the agency can present the work as its own. My advice is to never claim an in-house team you don't have. "We work with specialist partners" is true, defensible, and almost never questioned, whereas a discovered lie costs you the client and the referral pipeline behind them.

What margin do I need for reselling SEO to be worth it?

As a working floor, treat 33%, which is a 50% markup, as the minimum for a managed retainer. Below that, one awkward month of extra client hand-holding wipes out the profit. A thin pass-through with genuinely minimal involvement can survive on less, but at that point you should question whether you're adding enough to be in the chain at all.

Why is cheap white-label SEO risky if the margin looks great?

Because the margin percentage is applied to work nobody senior has touched, and the brand attached to that work is yours. When a £150-a-month package underdelivers, the client doesn't blame the invisible provider, they leave the agency. The wholesale saving is rarely worth what a churned client costs.
