Why Should a Business Hire an SEO Company Instead of Doing SEO In-House?
Hire an SEO company when you can afford one person but need several skills (technical, content, links, analytics) and want to scale spending up or down without hiring. Build in-house when organic search drives a large share of your revenue and you can fund a full team. A hybrid, with one internal owner and outside specialists, sits between the two.
First-Year Cost: One Hire Versus a Retainer
The salary is one line of an in-house hire’s cost. Revved Digital, an SEO agency, built a first-year estimate for one specialist in its cost comparison of agency and in-house SEO (October 2, 2025):
| Cost line | In-house specialist (Revved Digital estimate) |
|---|---|
| Base salary | $68,000 (Revved's range for an experienced specialist: $63,000 to $73,000) |
| Benefits | $23,800 (30% to 35% of salary) |
| Overhead: office, equipment, software | $17,000 (about 25%) |
| Administrative: accounting, legal, insurance, taxes | $12,240 (18%) |
| Onboarding: about three months of training | $17,000 |
| First-year total | $138,040 |
The lines add up to the total ($68,000 + $23,800 + $17,000 + $12,240 + $17,000 = $138,040). Three cautions apply. The estimate comes from an agency that sells the outsourcing side of this decision, so replace the salary line with a figure for your own market and role before you rely on it. The onboarding line equals three months of the $68,000 salary, and Revved describes it only as three months of training before the hire becomes fully productive; if it stands for the salary paid during those months, it is already inside the salary line, and the total would be $121,040. And the same page puts the agency side at “around $84,000 per year” without showing how it got there, while also listing agency fees from “$250-$750 per month” to “$3,000-$10,000 monthly,” so that figure is not a usable benchmark.
For the agency side, use survey data. In Ahrefs’ survey of 439 SEO providers (updated August 15, 2024), agencies averaged $3,209 a month, about $38,500 a year, and Ahrefs computed that average from the top of each price band, so it leans high. The in-house estimate and this agency average come from different sources and describe different scopes of work, so the gap between them is not a saving; compare totals only after pricing the same output on both sides, as in the test at the end of this page. How retainers vary by region, experience and scope is laid out in the typical pricing model of an SEO company.
Software already sits inside the overhead line above, so do not add tools to the total a second time; use the tool prices to check that line. Revved puts tools at $3,000 to $10,000 per tool a year, while published entry prices on October 21, 2026 were lower for some tools: Screaming Frog’s crawler license was $279 a year, Ahrefs’ Lite plan $129 a month and Semrush’s Pro plan $139.95 a month. For the full price list, see the tools an SEO company uses for analysis.
What a Retainer Buys That One Hire Cannot
A first-year in-house budget of about $121,000 to $138,000 on Revved’s lines buys one person’s hours. A retainer can buy part of several people’s time: a strategist, a technical specialist, a content lead, and sometimes a link-building or digital PR specialist. Technical SEO, content strategy and link acquisition are different skills, and one hire is likely to be stronger in one or two of them than in the rest.
Breadth counts only if the proposal names it. Check that it says who covers technical, content and link work and how many hours each gets; use the services a professional SEO company should provide as the scope checklist.
Ramp-Up on Both Sides
Revved estimates that building an in-house team “takes 3-6 months just to hire people,” plus training before the work reaches strategy. An agency can start faster because its specialists are already trained, but it still has to learn your site, competitors and customers. Expect its first one to three months to go to audit and foundation work; measure each stage against how long an SEO company takes to show measurable results.
Keeping Up With Google’s Changes
Google’s explanation of how it tests Search changes reports 4,781 launches, 16,871 live traffic experiments and 124,942 side-by-side experiments in 2023. A small number of changes are announced as named updates: Google’s ranking update history on its Search Status Dashboard lists three core updates and one spam update for 2025.
An agency watching many client sites can see an announced update land across all of them at once. An in-house specialist sees one site. What the specialist cannot easily replicate is knowing which fixes worked on other sites after the same update; public volatility trackers show that something moved, not what repaired it. That advantage exists only if the agency actually compares results across its clients, so ask it for an example from the last update.
When In-House Is the Better Choice
In-house is the stronger choice in three situations:
- Search is the business model. Marketplaces, publishers and large online retailers that depend on organic traffic for a large share of revenue have continuous search work, and product knowledge built inside the company keeps adding value.
- The budget covers a team, not one person. A lone specialist without content, development and analytics support carries the same breadth problem an agency solves. Revved estimates a full team of specialists, writers and technical staff at $300,000 to $500,000 a year.
- The work needs daily product or code context. Custom platforms, large catalogs and sites with frequent releases benefit from someone inside the product roadmap full time.
Flexibility and Exit Terms
An in-house hire is a fixed commitment: the salary, the training already spent and any severance you offer do not disappear if priorities shift. An agency’s exit cost depends on two contract terms, the minimum commitment and the notice period, so check both before signing; take the contract questions from the questions to ask before hiring an SEO company.
Scaling up follows the same logic. An agency can add content output or a technical sprint if its contract allows changes in scope, while an in-house team grows only as fast as hiring allows. The cost of that flexibility is attention: an agency splits its team across clients, and a company with a custom platform or a catalog that changes daily may find an agency’s standard process a poor fit.
The Hybrid Split
A hybrid divides the work. An internal marketer or content owner runs daily publishing, approvals, stakeholder requests and coordination with developers. An agency or consultant covers technical SEO, strategy, link acquisition and the analysis that needs paid tools. It fits a company that can fund one internal role but not a full team, and it gives the agency someone inside the business who can get its recommendations implemented.
A Test for Your Business
Price the team you would need in-house, at minimum a technical specialist, a content lead and part of a developer’s time, at fully loaded cost, using local salary data. Then compare that total with agency quotes for the same scope, measured in pieces of content a month, technical hours and link targets. If the in-house total is far above the quotes, start with an agency and bring functions inside as volume grows. If organic search already drives a large share of your revenue and you can fund that team, build it.
