What agencies actually keep: gross-margin bands by resold service line, the cost drivers that move them, and how account-management time erodes the headline number. Methodology published, free to cite with attribution.
Agency gross margins on resold marketing services cluster in a 30-70% band by service line in 2026 - link building and AEO/GEO highest (50-70%), content and web lowest (30-55%), SEO retainers around 55% median - all before account-management time.

Four structural drivers behind the bands.
The same wholesale cost yields a thin margin in a price-sensitive market and a fat one in a premium market. The biggest lever on agency margin is the retail price the market will bear - not the wholesale cost. Agencies that compete on price cap their own margin before fulfillment is even chosen.
Headline gross margin is computed before the agency's own hours. A 55% retainer margin can become a poor effective hourly if coordination, revisions and client comms balloon. The agencies with the healthiest real margins run tight scopes and senior fulfillment that needs little hand-holding.
Link building and AI-search sit highest because supply is scarce and value is legible; content sits lowest because AI has compressed production cost and buyers know it. Web has wide dispersion because project scope varies enormously. The service mix an agency sells largely determines its blended margin.
Sustained margins above the band usually mean promised scope exceeds purchased scope - a gap that surfaces later as underdelivery and churn. The healthiest books cluster inside the band, not above it. A margin that looks too good is usually a costing error or a retention risk.
Margin bands are gross margin on the client retainer, before account-management time. Bars span the band; the black tick marks the median.

The headline gross margin is the start of the story, not the end. Each layer of real cost erodes it - and the bottom line is agency-specific.
| Stage | Typical level | What it nets out |
|---|---|---|
| Headline gross margin | 55% | Retainer minus wholesale cost, before any of your time |
| After account management | ~45-50% | Net of the hours you personally spend per client |
| After sales & overhead | ~25-40% | Net of client acquisition cost, tools, admin (varies widely by agency) |
| Net contribution | varies | What actually reaches the bottom line - agency-specific |

Request the datasetAcross resold service lines, sustainable gross margins cluster in a 30-70% band depending on the service: link building and AEO/GEO at the top (50-70%), SEO and paid media in the middle (40-65%), and content and web at the lower-but-wider end (30-55%). The median across the common SEO retainer is around 55%. These are gross-margin ranges on the client retainer before the agency's own account-management time, synthesised from Nico Digital internal benchmark data and the 2026 pricing benchmark, June 2026.
Two opposite supply dynamics. AI has compressed content-production cost and buyers know it, so retail content prices have softened even as quality bars rose - squeezing margin from both ends. Editorial link building, by contrast, has scarce supply (real editorial placements are hard to earn) and legible value, so it holds a higher margin. Service-line margin tracks how scarce and how legible the value is.
Materially, and it is the number agencies most often ignore. A 55% headline gross margin can fall to an effective 45-50% once the owner's or account manager's hours are costed, and lower still after sales and overhead. The agencies with the best real margins pair tight scopes with senior fulfillment that needs little coordination, keeping their own hours per client low.
Most healthy reselling agencies run a blended gross margin in the 45-60% range across their service mix, before their own time. Below ~40% blended usually signals underpriced retail in the agency's market rather than expensive fulfillment; sustained above ~65% usually signals scope being shaved in ways that surface later as churn. Blended margin is largely set by which services dominate the mix.
Three source layers, in order of weight: Nico Digital internal delivery and partner-portfolio benchmarks across 175+ clients and 327+ campaigns; the publicly sourced wholesale and retail ranges in our White-Label SEO Pricing Benchmark 2026; and observed retail-retainer norms in the US, UK and Australian markets. All figures are ranges, not point estimates. The annual revision will add a structured partner-agency survey, with sample size and fielding window published alongside - no survey-based precision is claimed in this edition.

Three uses: benchmark your blended margin against the 45-60% healthy range and investigate if you are outside it; rebalance your service mix toward higher-band lines like AEO/GEO and link building where you can sell them; and cost your own account-management hours honestly before celebrating a headline margin. The margin and ROI calculators linked from this page do that arithmetic.
