If you’re choosing between hiring an SEO agency and hiring a senior SEO consultant, my answer is straightforward: hire the consultant. Yes, I’m biased. I run Oddo Digital, a solo SEO and AEO consultancy. But the bias comes from more than a decade of watching how agencies operate, and seeing what clients get versus what they pay for. Below is the head-to-head I run through with anyone weighing the two options.
Main takeaways
- At an agency, you don’t know who you’re working with until after you’ve signed.
- Communication runs through an account manager who isn’t the subject matter expert, which turns simple questions into multi-day games of telephone.
- The senior people who got promoted for their work are usually no longer doing the work. Junior staff and contractors execute. Seniors review on a deadline.
- An agency employee collects a salary either way. A consultant whose name is on the business has direct stakes in your results, because losing a client is a real hit.
- A larger share of every dollar you spend at an agency goes to overhead, status meetings, and admin. With a consultant, more of it lands on the actual deliverables.
- Productized agency retainers are locked a year in advance. A consultant can pivot scope on the fly when a launch, migration, or algorithm update demands it.
- Agency teams change. People leave, get promoted, or get pulled to a higher-paying account. Each transition costs you onboarding time you’re paying for.
- A consultant can plug into your Slack, your Teams, your inbox, and answer directly. No queue. No hand-off.
Team assignment
You don’t know who you’re getting until after you’ve signed.
When you talk to an agency in the sales cycle, you’re talking to the sales team. Maybe the founder or a VP shows up because they want to close the deal. The content you’ve seen online, the awards on the website, the case studies in the deck: none of that is the team that does your work.
Your team isn’t usually assigned until the contract is signed, and at that point it’s a scramble behind the scenes. Either they hire someone quickly because everyone is at full bandwidth, they slot you in with the newest person because the senior roster is full, or, if you’re paying enough, they pull a top performer off another client and move that person to your account.
The chances you get the agency’s top performers are slim unless you’re the highest-paying client on the roster. And even when you do, those people are often overworked, because agencies have to constantly grow to keep margin healthy, which means selling new contracts before figuring out staffing.
With a consultant, there’s no roll of the dice. You met me. I’m the one who’s going to do the work. Same person on the sales call, same person in your weekly meetings, same person writing the recommendations.
Structure and communication
The next problem is the chain you have to go through to get a question answered.
At most agencies, your point of contact is an account manager. Account managers are good at project management and client communication, but they’re not the subject matter expert.
They aren’t in Screaming Frog every day. They aren’t running competitor analysis or pulling AI visibility data. So when you send a simple question (something like “hey, what should we do with this title tag?” or “the core algorithm update just rolled out, do we need to react?”), the response cycle usually goes:
- The account manager acknowledges your message in 12 to 24 hours, sometimes 1 to 2 days.
- They tell you they’ll check in with the subject matter expert on the team.
- A few days later, you get the actual answer.
A question that should take 30 seconds to answer takes 2 to 4 business days to come back. Multiply that across a year of campaign work, and you’re losing real momentum to a communication chain.
When you work with a consultant, you skip the chain. I’m the one in your tools. If you Slack me a question, I read it, and I answer it. If I don’t know off the top of my head, I have a network I can ping or quick research I can run, but you’re getting a response in hours, not days.
Seniority and experience
Agencies make money from the spread between what they charge clients and what they pay staff. Healthy margin depends on getting a lot of execution work into the hands of more junior employees or outside contractors. That’s the math. No one agency is to blame. The model has to work this way to stay profitable.
But execution is also where you learn. Keyword research, competitor analysis, technical audits, on-page recommendations: doing those tasks over and over is how you get better at SEO. The senior people at an agency are senior because they did that work for years. Then they got promoted into manager roles, and now they’re overseeing teams, reviewing deliverables before they go out the door, sitting on status calls. They’re rarely the ones building the recommendations you receive.
Which means the strategy on your account often comes from the team members who haven’t yet built the reps to know better. Your senior reviewer is glancing at the work between four other client calls, on a tight deadline, before it ships out the door.
A consultant model is different. I’m the one writing the recommendations because I’m the only person on the engagement. Every junior or repetitive task I run is another rep that sharpens the next deliverable. Every strategy call is informed by the work I just finished, not work I last touched five years ago.
Accountability
The other side of the seniority issue is who has skin in the game.
At an agency, the people on your account collect a salary. That’s the reality of employment, not a knock on them. They want to do good work and they care about their internal reputation, but the financial consequence of an account going sideways is muted. As long as new sales outpace churn, the agency is fine, and the individual employee’s paycheck doesn’t change much either way. The incentive becomes efficiency: hit deadlines, ship the deliverable, keep the book full.
When you work with me, my name is on the business. The work ships under Oddo Digital, and I live and die with the results. I can only carry six to ten clients at a time, which means losing one is a meaningful hit to my revenue. That’s a different kind of motivation than collecting a check.
It also changes how I show up. I’m optimizing for the kind of work that earns a renewal and a referral, not just for shipping the deliverable. Those are how the business stays healthy.
The myth of agency support
A common pitch from agencies is the depth of bench. “We have a whole team behind us.” It sounds reassuring. In practice, it’s also a constraint.
When an agency needs to scale up your work, expand into a new discipline, or fill a gap they don’t cover well in-house, they can only pull from their own roster. If that roster is at capacity or short on the skill you need, you’re either waiting or getting a less-than-ideal fit. The “team behind them” is just their internal employees, who are managing other clients too.
I’m not constrained that way. I have direct relationships with senior-level contractors I trust, partner agencies that do white-label fulfillment, and other independent consultants who specialize in disciplines outside my core. When a client needs a video production partner, an extra set of hands on a website migration, or someone deep in paid media to complement organic, I can vet, negotiate, and bring them in faster than an agency that has to navigate internal staffing first.
As a senior consultant sitting at the center of strategy and communication, I have more usable support than an agency, not less. The difference is that mine is composed of people I’ve chosen to work with based on quality, not people who happen to share a payroll.
Budget efficiency
Agency overhead is the thing most clients don’t see until they’re already a few months in.
Think about your last status meeting with an agency. If they brought four or five people on the call, and only one or two of them did most of the talking, you probably just burned around $800 of your budget on a single hour. Agency rates run anywhere from $100 to $200 per hour per head, and every person on that call is logging that hour against your scope. Status meetings, internal QA, project management, time spent in their proprietary tools: all of it gets built into your pricing.
The more people who touch your project, the larger the percentage of your spend that goes to overhead before any deliverable lands. If you’re spending $100K a year with an agency, it’s not unusual for $30K to $40K of that to go straight to communication and admin work before you see a single recommendation.
With a consultant, you’re still paying for time spent on calls and admin. That’s unavoidable. But it’s one person doing it, and that person is the same one writing your strategy. The overhead percentage is far smaller, which means more of your spend lands on the deliverables. I can do more for less because the structure is leaner, not because I’m cutting corners.
Flexibility and agile support
Agencies productize their services because they need predictability. They have to manage bandwidth across dozens of clients, align scopes with the skill sets they have on staff, and protect the revenue model. So contracts tend to look like: a set number of pages a month, a set number of optimizations a month, a quarterly audit, monthly reporting. Locked in, often a year in advance.
That’s fine on paper, but real SEO work doesn’t follow a tidy monthly cadence. A product launches and needs net-new content support. A migration goes sideways and needs a technical audit yesterday. A core algorithm update lands and you need to react before competitors do. Something breaks on the site and you need eyes on it now. Rigid productized retainers prevent the kind of proactive and reactive support these moments demand.
When the scope needs to flex at an agency, it goes through an SOW change, internal resource planning, and a back-and-forth on what’s getting de-prioritized to make room. By the time it’s sorted, the moment has often passed.
I don’t have those hoops. If you need to pivot for a month because something came up, we pivot. If a special project shows up that wasn’t in the original scope, I can fit it in or repackage the engagement on the fly. Fewer hands on the contract means fewer hands needed to change it. The relationship is built around what your business needs that week, not around what I sold you in January.
Built into your team
The best client engagements don’t feel like vendor relationships. They feel like the consultant is a senior member of the marketing team who happens to invoice instead of getting a paycheck.
That’s much easier for a consultant to pull off. My calendar is mine. I can move things around to join a call your team scheduled this morning, without wrangling four other people’s schedules. I can sit in your Slack channel, your Teams workspace, your project management tool of choice. When something comes up, you ask me directly and I answer.
Agencies tend to require their own tooling because they’re managing dozens of clients across the same systems and they can’t have ten different setups per team. That’s a reasonable internal decision for them. It just makes them less embedded with you.
Change management
This is the one I see clients get burned on most often, and it doesn’t get talked about enough in sales cycles.
Agency teams are constantly in motion. People leave for other jobs. They get promoted off the execution side. They get reassigned to a higher-priority client. They get let go. Every transition means a new person on your account, and every new person needs to be onboarded to your goals, your products, your brand voice, your launches, your existing campaigns.
You end up paying the agency to learn your business. Then to learn it again. If it happens two or three times in a couple of years, you’ve spent a meaningful chunk of your budget catching strangers up to speed while you’re already managing your own team’s retention. That’s exhausting, it kills momentum, and it’s a big reason a lot of agency relationships eventually end with the client looking elsewhere.
I’m not going anywhere. The relationship doesn’t restart every nine months. The context I built about your business in year one compounds into year two, year three, and so on. I learn and grow with you instead of being replaced.

| Change management | Frequent staff transitions force repeated onboarding at your cost | Same partner across years; relationship and context compound |
A fair disclaimer
There are excellent SEO agencies out there with strong practitioners on staff, and there are weak SEO consultants who don’t have the depth they claim. Being a solo operator doesn’t automatically make someone good. Being part of an agency doesn’t automatically make someone a layer of bureaucracy.
Not every consultant beats every agency. The underlying structure of the agency model leans toward the problems above, and the senior-consultant model leans toward avoiding them. Match the right person to your work, regardless of which side they sit on.
For the work I take on at Oddo Digital across SEO strategy, technical audits, schema markup, AEO and LLM visibility, content briefs, and reporting, the consultant model holds up well against the agency comparison. Quicker response times, tighter communication, better spend efficiency, and a wider support network when it’s needed.
Want to talk about your search strategy?
If you’re frustrated with your current agency, or you’re evaluating one and want a second opinion before signing, I’m happy to talk it through. Most of my best engagements start with a 30-minute conversation about what you’re trying to accomplish and where things are stuck.
