Most businesses don't have an SEO problem. They have a model problem. They picked the wrong seo engagement for their business stage e.g. an agency before they had a plan, a consultant without a team to execute it, a full-time hire before SEO was even a proven channel. The results looked the same in every case: money spent, time passed, rankings flat, opportunity missed and no clear answer for why.
There are four ways to bring SEO into your business. This post breaks down exactly what each one is, what it costs and by the end of this post, you'll know which one fits your business right now.
Two questions cut through all the noise.
First: inside or outside? Fractional SEO and in-house hires work inside your business - in your Slack, on your roadmap, inside your weekly calls. Agencies and consultants work from outside, receiving briefs and sending deliverables.
Second: who owns the plan? Fractional SEO and in-house hires build the SEO plan and are accountable to it long-term. Agencies run the plan. Consultants hand you a plan and leave.
Keep that in your head. Everything below slots into it.
A fractional SEO is a senior person who works inside your business part-time. Not a vendor you brief but someone who actually owns your SEO growth. They decide what to prioritize, build the roadmap and stay responsible for whether it works.
This isn't an agency with a different invoice. A fractional SEO thinks like a Director of SEO. They make the calls a junior hire or agency account manager won't which keywords to ignore, when your category pages need a rebuild instead of more blog posts, why your technical issues are quietly killing your content investment.
One real limitation worth naming upfront: a fractional SEO is not a content team. The model works best when a writer is already in place, or can be hired alongside it. Plan for content capacity before you start, not after.
An agency is a team of writers, link builders, technical people, account managers built for volume. They're good at pushing work out efficiently.
That's genuinely useful when someone has already figured out the plan and the agency just needs to execute it. The problem is that agencies aren't built to think on your behalf. Without clear direction coming from somewhere, they produce activity. A lot of it. None of it necessarily pointing in the right direction.
One thing worth knowing: the person who sold you the retainer is rarely the person doing the work. After you sign, your account moves to junior staff. Agency turnover makes this worse because the one person who actually understood your business is gone six months later and you're starting over. This isn't a bad agency problem. It's just how the model works.
Full-time, fully inside your business. Your SEO person sits in the product meeting, has access to engineering product & content teams and works exclusively on your growth. Full ownership, full cost.
This makes sense when SEO needs 40+ hours of focused attention every week and when daily collaboration across product, engineering, and content is genuinely necessary - not occasional.
The year-one cost runs $180,000–$220,000 all-in before meaningful work starts. That's the right investment at the right stage. Before that stage, it's a lot of overhead solving a problem that doesn't yet require it.
A consultant delivers a specific thing: an audit, a keyword framework, a content architecture, a migration plan. They present it, answer follow-up questions, and the engagement ends.
That output can be genuinely valuable. The question is always what happens next and that part is entirely on you. If your team has the depth and bandwidth to work through a 47-item audit with good sequencing and judgment, the consultant model is efficient and affordable. If they don't, the document sits untouched.

The pattern the table shows: fractional SEO is the only model that combines internal integration, senior-level ownership, revenue accountability, and cost flexibility at the same time. Every other model trades one of those to deliver something else.
1. Early-stage or small teams. Your internal team is lean and SEO needs to be mostly outsourced. An agency gives you capacity without a full-time hire — writers, link builders, technical work all under one roof. The catch: someone still has to point them in the right direction and hold them accountable. If that job defaults to the CEO, that's not a good use of CEO time. → Start with an agency, but plan for someone to manage them.
2. Post-PMF, $2M–$20M ARR. You know who you're selling to. You have or can hire a writer. You need someone senior embedded in the business — not a monthly report from an account manager juggling 11 other clients. The cost gap makes this clear: fractional SEO runs $30,000–$60,000 a year at a standard tier. The fully-loaded in-house alternative is $180,000–$220,000 in year one. Same quality of thinking, zero ramp time, no equity. Fractional SEO is the right call here.
3. Mature company with a content team already in place. The writers exist, the technical resources exist, someone can execute. What's missing is a fresh outside perspective on why growth has stalled. Bring in a consultant to reset the plan. Let your team run it.
4. Series B and beyond. SEO is your primary growth channel. The budget absorbs $180,000–$220,000 in year one without stress. Product, engineering, and content need to work together daily in ways a part-time engagement can't fully cover. An in-house SEO Director is now justified.
5. Need both a plan and the people to execute it. SEO is already working. You have or are bringing on a fractional SEO, but you need more volume than they can produce alone. The hybrid setup = fractional SEO managing an agency - closes both gaps.
What fractional SEO can't do: It's not a content team. Output volume is limited compared to a full agency. Works best when a writer is already in place or hired alongside it. Not the right model when SEO genuinely needs 40+ dedicated hours a week at scale.
What an agency can't do: Can't own your plan. Can't tell you whether you're targeting the right people. Can't connect what they're building to your revenue without someone internally holding them to that. And again the person who understood your business during the sales call often isn't the person doing the work.
What an in-house hire can't do: Can't be quickly undone when the business shifts. Carries 60–90 days of ramp cost before real output starts. Doesn't make sense before SEO is a proven, primary growth channel, too expensive to treat as a test.
What a consultant can't do: Can't own what happens after the document lands. Can't be there four months later when the plan needs to change. It's a snapshot of your website valuable at the right moment, not a long-term growth mechanism.
This setup is underused and often the highest-performing option for growing companies.
The fractional SEO owns the plan and manages the agency as a vendor, holding their work accountable to whether it's actually generating leads or signups — not just whether the articles went live. The agency handles volume: content, links, technical work.
A typical setup: $3,000–$5,000/month fractional SEO managing a $4,000–$8,000/month agency. Total cost sits well below a full-time hire plus a content team, and the accountability is tighter than either model running independently.
This works when SEO is already a validated channel, you need both a plan and the people to execute it, and you don't have internal content capacity but you do want someone senior watching the quality across the whole thing.
