[In a Harry Hill voice…]
So which is better? SEO consultant or SEO company?
There’s only one way to find out… FIGHT!
I’m joking, this is a stress-free zone, so there’s no need for any untoward behaviour.
The “SEO consultant vs SEO agency” question comes up in almost every first conversation I have with a prospective client, and the honest answer is that it depends (typical SEO answer) on your budget, your in-house capability, and how much of the work you need done for you. I’ve spent over 25 years on both sides of that fence, so rather than give you the generic pros-and-cons list you’ll find on a thousand other marketing blogs, I’ll tell you first-hand what I’ve actually seen from inside an agency and as an independent consulting freelancer.
The Definition of an SEO Consultant and SEO Agency
Before we launch into our analysis, I’m going to define each entity from my own perspective:
SEO Consultant
SEO consultants can just consult, but in my own twenty-five years of experience, I consult and I implement the SEO tasks I recommend. So I’m going to approach this post from the point of view that SEO consultants can either just provide advice or offer both the advice and the work.
SEO Agency/Company
I’m using the words “agency” and “company” interchangeably because they’re different and the same in my eyes. SEO companies usually have more than one SEO practitioner and, as a company or agency, may offer other services too. Plus, by the very nature that they’re more than one person, there’s a bigger supporting structure: the CEO or MD, maybe finance and HR departments, plus admin, support, and other creatives such as designers, PPC and social media professionals.
That supporting structure matters more than most comparison articles admit, because you’re paying for it whether you use it or not. More on that in the cost section below.
TL;DR: SEO Consultant vs SEO Company
If you wanted me to tell you quickly what I think, here’s the top-level comparison:
| SEO Consultant | SEO Company | |
|---|---|---|
| Who does the work | One expert, start to finish | A team, often with juniors doing the day-to-day |
| Depth of experience | Can be very deep (one person, decades of it) | Broad, but depth varies by who’s on your account |
| Services | SEO, sometimes adjacent skills like copywriting or PPC | Full-service: SEO, PPC, social, design, development |
| Cost | Hourly, day rate, or project fee; lower overheads | Monthly retainer; you fund the office and the org chart |
| Communication | Direct, with the person doing the work | Usually via an account manager |
| Capacity | Limited: one pair of hands | Scalable: can absorb big or fast-growing projects |
| Best for | SMEs, specific problems, hands-on partnership | Larger businesses, multi-channel campaigns, volume |
If you want to make a decision on whether to employ an SEO consultant or an SEO agency, you’ll need to come to your own conclusion based on the pros and cons. So read on for the full insight into whether you should employ an SEO consultant or an SEO company.
Disclaimer
You may be thinking that, as an independent SEO consultant myself, I’m going to bang on about the advantages of a solo SEO expert over the SEO agency, but let me just make this early disclaimer:
For over a year I was the SEO Manager at Air Social, a marketing agency in Guildford, Surrey.
Prior to that I was the digital marketing manager for Clever Marketing, another full-service marketing outfit who were originally in Woking (Surrey), then Farnborough (Hampshire), and finally settled back in Surrey (Camberley). I started as the sole digital marketer in that firm back in 2017 and managed to single-handedly perform all of the SEO, PPC, social media, and content writing duties for the first few years. I managed as much of the work as I could for nearly two years, generating leads and generating too much business for my department of one.
At the tail end of the second year, I took on a dedicated Pay Per Click (PPC) manager to help me out with that side of the workload. Then, after taking on as much work as we could without breaking (too much), we urgently needed more help. The digital marketing team of two experts eventually expanded to a team of four, two of us on each of the SEO and PPC sides of the department. We also added two account managers and two web developers, so the agency grew somewhat in my nearly eight years there.
At is4profit.com too (2000 to 2014), we designed and built websites, then SEO’d them. However, that business made sure not to call itself an agency, as that was just one offering in its large stable of SME services.
So I’ve seen the digital marketing agency side of things and, since 2000, I’ve had a foot in both camps: being an independent SEO consultant all that time while conducting SEO and other digital marketing duties across the same 25 years for small businesses, national charities, and global corporations.
There are pros and cons to each option, and I’ll dwell on the positives of both sides, because I’m happy to suggest whichever is the most appropriate solution for the client’s needs. After all, the customer is king, right?
One thing worth remembering before we start: the very best SEO consultants can do as much work as some SEO companies, if not more. One SEO consultant with 25 years’ experience may well have more expertise than an SEO company with four experts who each have five years’ experience. I’ve been both of those things, so I say that with a straight face.
1. Scope of SEO Services
SEO Consultant
Firstly, there’s consulting as a singular top-level discipline, and secondly there’s consulting with the ability to carry out the recommendations. This distinction is the single most important question to ask any consultant you’re considering, because the market contains both types and they behave and can cost you very differently, with different outcomes.
An advice-only consultant will audit your site, research your keywords, analyse your competitors, and hand you a strategy document or roadmap. That’s genuinely valuable if you have an in-house team or a web developer who can implement it. But I’ve reviewed plenty of websites over the years where a beautifully written SEO strategy has sat in a drawer for eighteen months because nobody in the business had the time or the skills to action it. A roadmap that nobody drives forward is just an expensive PDF.
On the other hand, a full-service, hands-on consultant does the audit and the implementation: the technical fixes, the on-page optimisation, the structured data, the content writing, the lot. That’s the model I work to. I’ll advise you AND carry out all the SEO work, which means nothing gets lost between the strategy and the execution, because the same brain is doing both.
SEO Company
SEO companies tend to offer a more comprehensive suite of services: technical SEO implementation, on-page optimisation, off-page work such as link building and outreach, content creation, and performance reporting. Crucially, they have the manpower to complete the tasks that a digital marketing strategy demands, and often across multiple channels at once. If you want SEO, PPC, social, and a website rebuild handled under one roof, an agency is built for exactly that.
The trade-off, which I have seen from the inside, is that the senior expert who impresses you in the pitch meeting is not always the person doing your keyword research on a wet Tuesday. Agencies scale by delegating, and delegation usually flows downwards to the more junior members of the team. That’s not a criticism, it’s simply how the economics of an agency work, but it’s worth knowing when you’re comparing a £2,000-a-month retainer against a consultant’s day rate. Additionally, you’re paying for the brand, it’s premises, an account manager, the digital marketing team, and probably the sales team and of course the MD and owners’ salaries in there.
2. SEO Expertise and Specialisation
SEO Consultant
A consultant’s expertise is concentrated in one head, which cuts both ways. In my case, nearly 26 years in digital covers technical SEO, local SEO, WordPress SEO, structured data, content strategy, and now the newer disciplines of AI SEO, answer engine optimisation (AEO)/generative engine optimisation (GEO). One person genuinely can cover that range if they’ve been doing it long enough and keep learning, and the advice you get is grounded in things they’ve personally implemented, broken, and fixed.
The honest limitation is that no individual is world-class at everything. If your project genuinely needs, say, enterprise-scale international SEO across twelve language markets, a lone consultant should tell you so and point you towards a team. The good ones do. Either that or they have the intelligence, capability, and experience to recommend a highly-efficient process that handles big projects in smaller bitesize tasks. It is doable with the right consultant.
SEO Company
An SEO agency employs a team with (hopefully) diverse skills, and the best agencies really do have a specialist for every corner of the discipline: a technical lead, content people, link builders, data analysts. The breadth is real.
What I’d gently challenge, from over nine years inside a digital marketing agency, is the assumption that breadth automatically means depth. Four people with five years’ experience each is twenty years of experience on the org chart, but it’s not the same as twenty years in one practitioner’s head, because the four haven’t lived through the algorithm updates, the recoveries, and the migrations that the one has. When you evaluate an agency, ask who specifically will work on your account and what they’ve personally shipped. If the answer is vague, that tells you something.
3. Cost and Budget
SEO Consultant
Consultants typically charge hourly, daily, or project-based rates, or a monthly retainer for ongoing work. Because a consultant carries almost no overhead (no office lease, no account managers, no HR department), far more of every pound you spend goes on actual SEO work. As a rough guide, UK freelance SEO consultants commonly charge somewhere between £50 and £100 per hour depending on experience, with monthly retainers for SME work often starting around a few hundred pounds.
I’m still trying not to be biased here, but I can do as much SEO as some small digital marketing agencies, if not more, for roughly half the price, and that’s not because I’m undervaluing my time or wilfully undercutting them to win business; It’s because you’re not paying for my office, my finance department, an account management layer, multiple exotic holidays a year nor flash cars, since I don’t have any of those things.
SEO Company
Agencies usually charge monthly retainers or project fees, and for UK SMEs those retainers commonly sit anywhere from around £1,000 to £10,000+ per month depending on scope and ambition. Some of that premium is legitimate: you’re buying capacity, continuity of cover, and a breadth of services one person can’t match. The smallest £1,000 a month retainers at an agency are often tight – having to discover, scope, do the work, and report is a lot to do and often “not worth getting out of bed for” at most agencies. Those size retainers are often best left to the freelancers.
But here’s the observation from my agency years that I think every buyer should hear: agency pricing tends to reflect output rather than outcomes. Retainers are often structured around hours delivered or deliverables shipped per month, because that’s what keeps the agency’s utilisation targets happy. Whether those deliverables move your rankings and revenue is a separate question, and it’s the only question that should matter to you. Whichever route you choose, tie the engagement to outcomes, not activity. In fact, if you’re contemplating employing an agency, ask them if they understand OKRs rather than KPIs. You can thank me for that later.
4. Communication and Collaboration
SEO Consultant
With a consultant, you speak directly to the person doing the work. When something changes (a Google core update lands, your developer breaks the sitemap, a competitor overtakes you), you can pick up the phone and get an answer from the person who’ll fix it, usually the same day. There’s no ticket queue and no “I’ll check with the team and come back to you.” It’s an agile, direct working relationship, and for most organisations, be they sole traders, small firms, or charities, it’s the thing clients tell me they value most.
SEO Company
With an agency you’ll usually have a dedicated account manager, and a good one is genuinely worth their weight in gold: they’re organised, responsive, and great at keeping multi-channel projects on the rails. The structured project management of an agency is a real advantage on complex work.
The risk, and I watched this happen from the delivery side, is the Chinese whispers effect. The client explains a problem to the account manager, the account manager writes it up in a brief, the brief lands with the SEO team, and somewhere along that chain a crucial detail evaporates. The work comes back not quite right, the correction goes back up the same chain, and a task that a direct conversation would have resolved in ten minutes takes two weeks and three meetings. Good agencies minimise this. None eliminate it entirely, because it’s structural.
5. Scalability
SEO Consultant
Let’s be blunt here: a marketing consultant is one pair of hands, and capacity is the genuine limitation of the individual consulting model. There’s a strong chance that I may not be able to run simultaneous full-scale campaigns for twenty clients (That would be two hours dedicated to each every day of the week). Any consultant who claims they can is either a pan-dimensional super being, outsourcing on the quiet, or spreading themselves dangerously thin. If your business is scaling fast, operates across many markets, or needs constant multi-channel output, a solo practitioner will probably and eventually become the bottleneck; an honest consultant will tell you before you find out the hard way.
SEO Company
This is where agencies earn their money. A team can absorb sudden increases in workload, cover holidays and sickness without your campaign stalling, and resource large, complex projects such as major site migrations or international rollouts. If you need volume and continuity above all else, the agency model exists precisely for you.
Reasons to Choose an SEO Consultant
- You need expert advice and strategic guidance from someone senior, not a team of juniors,
- You have an in-house team that can implement SEO recommendations,
- You don’t have an in-house team BUT you’ve found a full-service SEO consultant who implements as well as advises,
- You have a limited budget and want it spent on work, not overheads,
- You need highly specialised expertise in a particular area,
- You want a personal, direct working relationship with the person doing the work.
When to Choose an SEO Company
- You need a comprehensive, multi-channel solution: SEO plus PPC, social, design, or development,
- You don’t have an in-house SEO team and need everything done for you at volume,
- You have a larger budget and need the capacity that comes with it,
- You need to scale your SEO efforts quickly or across multiple markets,
- You want the continuity of a team that doesn’t take holidays all at once.
Frequently Asked Questions
Is an SEO consultant cheaper than an SEO agency?
Usually, yes. A consultant’s rates carry minimal overheads, so more of your budget goes on actual SEO work rather than office space and account management. An agency retainer buys you capacity and breadth that one person can’t offer, so the right question isn’t “which is cheaper?” but rather “which gives me the better outcome per pound?”
Can one SEO consultant really replace an agency?
For most small and medium-sized businesses, yes, provided the consultant implements as well as advises. One experienced full-service consultant can cover strategy, technical SEO, on-page work, and content. Where a consultant can’t replace an agency is raw capacity: large-scale, multi-market, or multi-channel campaigns need a team.
What should I ask before hiring either one?
Ask your prospective consultant or marketing agency these three questions:
- Who exactly will do the work on my account?
- Can you show me outcomes (rankings, traffic, leads) you’ve personally achieved for similar businesses?
- And is the engagement priced around activity or results?
The answers to all of these pertinent questions will tell you more than any pitch deck can. Remember that pitch decks are designed to win business and if it’s the sales team (or ego) who control that output, then managing client expectations can often be an aside to getting the numbers into accounts. How often have you seen quotes like “we’ll skyrocket your results” only for the outcome to be more of a damp squib?
Do SEO consultants only give advice?
Some do, and that’s fine if you have an in-house team to implement that advice. Others, myself included, consult and carry out the work: audits, technical fixes, structured data, content, the lot. Always confirm which type you’re talking to before you sign anything.
Conclusion
As mentioned, I’ve approached the SEO consultant role as being more than just a consultant, with the option of them actually performing the SEO work they recommend. This may not always be the case, so you’ll need to confirm that with anyone you speak to.
The only reason I’ve done this is because, as an experienced SEO consultant myself, I also “roll my sleeves up” and very much “get stuck in” with the work that needs doing. I’m a full-stack marketer, so I can consult for you AND do all the work you need.
I’ve also experienced the distance from the client that comes with an account manager in the middle. Whilst there are benefits to having a single point of contact, there’s also the risk of information getting lost between the customer and the implementation team. With an independent SEO consultant, you liaise directly with the person doing the work, who can very quickly communicate, question, convey, and clarify.
