SEO agency vs in-house

We are an agency, so we have an obvious interest in one of these answers. Nobody in this industry gives a straight answer on this question because they are either selling agency services or defending an in-house team. What follows includes the cost math that favors in-house, the stage at which we would tell you to stop using us, and the arrangement we actually recommend most often, which is neither of the two options in the title.
Agency or in-house SEO?
Below roughly $2M ARR, hire an agency or a consultant. Between $2M and $10M, run a hybrid: one in-house owner plus outside specialists. Above $10M, build the team and keep a partner for technical, digital PR and AI-search work.
The number that decides it: a senior in-house SEO costs $120,000 to $180,000 fully loaded, which is $10,000 to $15,000 a month for one person. Nobody is strong at strategy, technical, content and links simultaneously, so at that price you are buying depth in one area and gaps in three.
The real cost of an in-house SEO hire
Most comparisons use base salary, which understates the true figure by a third or more. Here is the arithmetic that belongs in the board deck.
Base salary $95,000 to $140,000
+ benefits, payroll taxes, equipment (roughly 25 to 30%)
+ tools $6,000 to $24,000/year
= $126,000 to $200,000 in year one
The comparison people actually want is what that same $10,000 to $16,000 buys from an agency. The answer is a technical specialist, a content operation, an outreach team and a strategist, none of them full-time on your account but all of them senior in their lane. Whether that beats one excellent generalist depends almost entirely on whether your bottleneck is breadth or depth.
If the in-house hire leaves after fourteen months, which is close to the industry average tenure, you absorb severance, rehiring cost and three to five months of stalled momentum. Agency risk is thirty days' notice. That asymmetry rarely appears in the spreadsheet and it matters more than the monthly difference.
Agency, in-house and freelancer compared
On the dimensions that actually change the outcome, rather than the ones that make either side look good.
| In-house hire | Agency | |
|---|---|---|
| Effective monthly cost | $10,000 to $16,000 for one person | $5,000 to $25,000 for a team |
| Coverage | One skill set, deep in one lane | Specialists across strategy, technical, content, links |
| Product knowledge | Deep. Lives with it daily. The genuine advantage. | Learned in weeks, never as deep |
| Time to productive | Two to three months hiring, then ramp | Around two weeks |
| Pattern recognition | One site, one algorithm history | Many sites, many recoveries and failures |
| Tooling | $500 to $2,000/mo on top | Included |
| Risk if it fails | Severance, rehiring, months lost | Thirty days' notice |
| Internal influence | High. Can push engineering directly. | Lower. Depends on an internal sponsor. |
| Scales by | Hiring, slowly | Adjusting scope, immediately |
What to do at each stage
Revenue is a cruder signal than bottleneck, but it is the one most teams actually have to hand.
Under $2M ARR
$2M to $10M ARR
Above $10M ARR
Any stage, one defined problem
Hire in house when SEO is already working and you need someone to run it consistently. Hire an agency when it is not working and you need to find out why. Hiring a full-time person to diagnose a problem you cannot describe is the most expensive way to answer that question.
How to run the hybrid without it falling apart
The hybrid is the right answer for most companies between $2M and $10M ARR, and it fails often enough to be worth covering properly. It fails for one reason: the split was never written down.
- The in-house owner holds priorities and product context. They decide what matters this quarter and translate the roadmap into what the agency should target.
- The agency holds execution depth. Technical diagnosis, content production, outreach, and measurement setup.
- Write down who owns engineering tickets. This is where hybrids die. The agency specifies, the in-house owner gets it into a sprint. If nobody owns that handoff, fixes sit in a backlog for a quarter.
- One reporting view, not two. Both sides working from the same dashboard, so nobody is comparing different numbers in a meeting.
- Agree what happens when they disagree. The in-house owner should have the final call, and the agency should be free to record that it disagreed.
Ask a prospective agency how they would work alongside an in-house lead, and whether they have done it. An agency that only knows how to own everything will quietly compete with your hire rather than complement them.
We are built for the hybrid, not against it
Most of our clients have someone in house. We work inside your tools, ship into your review process, and take direction from your marketing lead rather than trying to own the function. When the honest read is that you should hire rather than extend a retainer, we say so, which is a strange thing for an agency to write and the reason we are writing it.
- We take direction from your in-house lead rather than routing around them
- Specialists across technical, content, links and AI search, which one hire cannot cover
- Senior operator on every call. The person who plans it runs it
- We mine your sales calls so product context transfers rather than staying locked in one head
- We will tell you when to hire instead. Above $10M ARR that is usually the right move
