SEO agency vs SEO consultant: Which is best for you?

You need SEO help.

The question is whether you hire an agency or work with a consultant. And like most things in SEO, the answer is (probably annoyingly) situational.

The reality?

Both models work.

But they work for different situations. And choosing the wrong one means you’ll either waste money on services you don’t actually need or get stuck with months and months of “strategy” decks that never turn into actual results.

I’m a bottom-line-up-front kinda guy, so let’s jump right into the short answer first (then go deeper afterwards).

The short answer…

If you already have a senior-level SEO in-house and a validated strategy you’re confident in that just needs extra gas poured on top—you can jump straight to an agency.

If you don’t have a senior-level SEO in-house and aren’t confident in your strategy—working with an SEO consultant first will virtually always be the best path.

After you work with a consultant to map out the path forward, that’s when you can potentially engage an agency. Do it before, and you could wind up running full speed in the wrong direction, publishing dozens of bad-fit content assets.

Summarizing:

• Start with a consultant to set the direction and validate the strategy
• Then tap an agency to help execute lots of things faster (if you need to)

Now let’s go deeper.

First, what makes consultants and agencies different in the first place? Aren’t they just SEO providers that do SEO?

What are the main differences between an SEO agency and SEO consultant?

They are different—and understanding those differences matters more than you’d think.

Level of implementation support

SEO agencies (or content marketing agencies) are usually good at producing lots of things quickly.

The quality of those things definitely depends on the agency. But the fact is, most agencies have large in-house teams, meaning they have the capacity and resourcing on-hand to execute lots of things. B2B SEO example—if you want to produce 100 articles in a quarter, an agency is far more likely to say yes and deliver.

SEO consultants are usually best at setting direction, not being the sole implementor of everything—especially if the plans include publishing lots of new pages.

The reality is, most consultants are solo. Some may have small teams or partners they work with, but most just won’t have the literal hours in their calendar to help turn the crank the same way an agency could.

Depending on the strategy and scale, some consultants will still be able to directly support with implementation. For example, if the plan is to only produce a few assets—most can help. Or if the focus is on running smaller, more targeted SEO experiments across content that already exists—most can help with that too.

But if you want to produce 100 articles in a quarter?

Most consultants can’t directly help with that (and a good one will probably try to talk you out of chasing volume like that).

Access to true expertise

Agencies (especially big ones) are notorious for putting clients on the 282 cycle:

• First 2 months—A team, smart operators, you feel good
• Next 8 months—C team, juniors with little to no oversight, you feel bad
• Final 2 months—A team comes back to sell you another 12 months, you feel iffy

This means you’re likely working closest with SEOs still early in their career that haven’t seen as much as a more senior-level SEO. They’re also likely following templated SOPs focused on outputs rather than deeply analyzing scenarios and making adjustments based on the business, the market, the audience.

Consultants are essentially the exact opposite.

With solo or small consulting firms especially, you’re working with the most senior person—the consultant themselves—the entire time, so no getting handed off to a junior team.

A consultant has likely gotten more exposure to different scenarios and hurdles over their career, and they have a better sense of what’s most likely to work (and what’s likely to flop).

Because they’re more senior—they also typically aren’t afraid to push back if they disagree, which a less experienced or senior agency team may not do (especially if your day-to-day interactions with the agency funnel through account managers that aren’t actually skilled SEOs).

Breadth vs depth

Most agencies consider themselves “full-service” agencies.

Which mostly just means if you give them money, they’ll figure out a way to execute on whatever the thing is—even if it’s not a core competency of theirs.

• SEO audit? Sure, that’ll be $10K.
• PPC strategy? Sure, that’ll be $10K.
• Influencer campaign? Sure, that’ll be $10K.
• TikTok videos? Sure, that’ll be $10K.
• Email drip campaign? Sure, that’ll be $10K.

You get the picture.

Again, most consultants are the opposite.

They have deeper expertise in a few areas and say no more than they say yes. They generally have a few specific problems they’re masters at solving because they’ve seen it and done it hundreds of times before.

Contract flexibility and commitment length

Agencies love their 12-month contracts with buyout clauses.

Once they’ve got you locked in, there’s way less pressure to actually deliver results month-over-month. If performance tanks in months 3-7, you’re still stuck paying out the contract (or paying to get out of it). This misaligns incentives—they’re guaranteed payment regardless of results for the next year.

Consultants typically work month-to-month or on shorter-term contracts with no cancellation fees.

If they’re not delivering, you can walk away cleanly. This forces them to actually perform every single month to keep you around. The incentive structure is way better aligned with your outcomes.

Speed to value and time to results

Agencies often spend months in “strategy phase” before executing anything.

The first ~90 days is all discovery, audits, and strategy deck building.

Which really just means sitting on 2 hour long calls with account managers and junior SEOs re-hashing all the same info you already provided during onboarding, and being presented with cookie-cutter decks that might as well have been created in 2010.

(And half the time, you’ll spot a different company’s logo buried somewhere in the deck because it was CLEARLY just a template they duplicated)

You’re paying $20K/month but not seeing any actual work get done. By the time they start executing, you’re 3 months and $60K in with zero results to show.

Consultants can usually start executing within days or weeks.

Most good SEO consultants don’t need a 120-slide strategy deck and 200-point “SEO audit” before taking action. They identify high-impact opportunities fast and start pulling levers. You see movement and early wins much faster, which builds confidence in the relationship.

What do most SEO consultants offer?

Here’s what you typically get when working with an SEO consultant (keeping in mind that every consultant is different).

SEO strategy guidance

This is the bread and butter for most consultants.

They’ll help you figure out which topics you should actually be targeting based on what your best customers are searching for. Here’s what good consultants typically look for and offer guidance on:

• Which searches indicate actual buying intent for YOUR product (not just “high-volume keywords”)
• Use case content, comparison pages, alternative pages—the stuff that drives pipeline
• Content gaps where competitors are visible, but you’re not
• Topics your sales team wishes prospects understood before the first call
• Bottom-up prioritization (highest value opportunities first, not biggest traffic numbers first)

They’ll map out a prioritized roadmap of what to tackle first, second, third. They’ll typically challenge your assumptions if you’re focused on the wrong things. For example, if you want to write 50 “what is…” glossary posts, a good consultant will push back and redirect you toward higher-value topics.

Content and technical SEO audits

I’ve never loved the word “audit” but it’s what most B2B businesses are familiar with, so I’ll use it here.

Consultants are great at taking a look beneath the hood—reviewing existing content, the technical foundation of your website, past performance and volatility. Think of it like talking to a specialist to diagnose any problems before you just take the whole car apart or start bolting on new parts or patches.

The best audits also aren’t just 200-points checklists where everything is presented as being an equal priority. They tell you the 5-10 things that actually matter and will move the needle. Everything else is noise you can ignore.

Site structure recommendations

How your site is organized matters for both user experience and search visibility. Consultants will typically review your URL structure, internal linking, and navigation hierarchy. They’re asking:

• Are your most important pages easy to find for users, search engines, and AI agents?
• Are you siloing related content together in ways that build topical authority?
• Is your conversion path clear, or are visitors getting lost?

This is especially valuable if you’ve been publishing content for years without much structure planning. It’s real easy for a website to spiral out of control when no one’s reeeeeeally been paying much attention to structure, hierarchy and organization along the way.

Fractional and embedded SEO services

Some consultants also offer fractional or embedded arrangements where they act as an ongoing strategic partner integrated into your team, not just on project-based work.

This means regular check-ins, continuous optimization guidance, and being available for questions as they come up. It fills the gap between hiring a full-time senior SEO (which can be $140K+ annually fully loaded) and one-off project consulting that leaves you without support after delivery.

You get senior expertise consistently involved in your strategy without the overhead of a full-time hire.

What do most SEO agencies offer?

Here’s what you typically get when working with an SEO agency (though offerings vary widely).

Full-service content production

This is where agencies shine—high-volume content production.

They have teams of writers, editors, and designers who can produce dozens of assets every month. Quality varies significantly from agency to agency (some produce excellent work, others churn out mediocre filler), but their capacity advantage is undeniable.

If you need 20-50+ pieces of content per month, agencies have the infrastructure to deliver at that scale. Most consultants simply can’t match that volume.

Link building campaigns

Similar story here. Agencies typically have the human capacity to offer dedicated link building services, with outreach teams in place for contacting sites for backlinks, guest posting programs, digital PR campaigns.

They have the capacity to run large-scale outreach that individual consultants typically can’t manage. Quality matters a ton here though—good agencies build real relationships and earn legitimate placements, while bad ones spam low-quality sites or buy sketchy links through PBNs (private blog networks).

Personally, I’m of the mindset that link building is becoming less important than it used to be as search algos are getting better and better, plus AI search isn’t as reliant on links alone. Still, it can be valuable when done right and for the right website or company.

Technical SEO implementation

Agencies typically have technical teams that can handle implementation work on your website—site speed optimization, schema markup, crawlability fixes, mobile optimization, and so on.

This is valuable if you don’t have developers in-house or your dev team is backlogged with other priorities.

Consultants can usually identify what needs fixing (the audit part) but may not have the technical resources to actually implement the fixes themselves. So if your site needs heavy technical work, and you don’t have internal resources, agencies have an edge here.

Local SEO services

If you have a larger website with lots of regional pages or local offerings—that requires lots of time and oversight to manage well.

For example, if you’re trying to rank in the local map packs across 50+ major cities in the US (let alone internationally), you’ll likely need multiple people monitoring and tinkering every week—especially if you’re in a high-value space with lots of competition.

Consultants generally won’t have the time to do it effectively. They’re better used as the overall strategic direction-setters who may oversee an agency that’s implementing.

What does each actually cost (and what are you paying for)?

Money talks, so let’s get specific about what you’re actually spending and what you’re getting for that spend.

SEO consultant pricing

Consultants typically charge anywhere from $3K-$15K per month, depending on:

• Their level of expertise and track record
• How involved they’ll be (strategy-only vs strategy + some execution)
• Whether it’s project-based or ongoing retainer

On the lower end ($3K-$5K/month), you’re usually getting strategic guidance and direction but minimal hands-on execution. On the higher end ($10K-$15K/month), you’re getting what I call “fractional SEO” support—someone effectively embedded with your team who’s involved weekly and doing hands-on work.

No big teams, no office overhead, no account manager layers. You’re paying for senior-level expertise, period.

For example, with Backstage SEO I’ve got an Advisory tier that covers strategy and direction, or a Growth tier that covers strategy and direction as well, but also includes done-for-you content execution.

SEO consultant vs full-time in-house SEO hire pricing

When you stretch the numbers, you can compare consultant pricing against hiring a full-time SEO in-house as well. An average SEO specialist salary is ~$85K/year. Factor in SG&A, benefits, taxes, and overhead, and you’re at $100K+ annually for a specialist with just a couple years of experience (if that).

Here’s how that breaks down:

The bottom line is this:

~$3-5K/month gets you senior-level direction for 40% less than an entry-level specialist. And ~$6-8K/month gets you senior-level direction plus execution for roughly the same cost as a specialist—without the people management overhead or the commitment headache.

SEO agency pricing

Agencies typically start at $10K-$15K per month on the low end and go up from there:

• Small agencies are in the $10K-$15K per month range
• Mid-size agencies are usually $15K-$30K per month
• Large agencies can be $30K-$100K+ per month

What are you paying for?

Teams, infrastructure, overhead, processes, account managers, project managers, junior executors, senior strategists (who you rarely see after month 2).

The math is pretty simple—if an agency charges $20K/month and assigns 4 people to your account, each person is only allocated $5K/month worth of time. And none of those 4 people are working on your account full-time. You’re getting slices of time from multiple people, coordinated by an account manager.

You’re betting that the efficiency of their systems and processes justifies the higher cost compared to a consultant.

In-house SEO team costs

Just for comparison, let’s keep the thread going on hiring in-house full-time vs bringing in a consultant or agency instead.

An entry-level SEO specialist will run you about $85K on average, with most landing in the $75-95K band.

Factor in SG&A, benefits, taxes, and overhead, and you’re looking at an all-in cost of $90K-$110K annually. But if they’re entry-level, you’re also spending 3-5 hours per week training them, reviewing their work, course-correcting. That’s 150-250 hours of YOUR time per year—at your salary, that’s expensive. At the same time, they’ll be truly OWNING search as a channel. You’re essentially paying them to learn on the job.

Senior SEO managers are closer to the $110K-$140K salary range, which translates to $130K-$180K fully loaded. Less hand-holding needed than with a specialist, but also tougher to find good ones and longer hiring timelines (3-6 months).

For most B2B SaaS companies with $3M-$50M in revenue, hiring full-time is overkill.

You don’t need 2,080 hours per year of SEO work. You need maybe 500-800 hours of strategic, high-leverage work. A consultant or fractional provider gives you exactly that.

So when is each a better fit than the other?

We’ve covered what each offers and what they cost. Now let’s talk about when each actually makes sense.

When an SEO agency is best

If you already have an established in-house team with senior-level SEO expertise (not just technical doers or junior SEOs) plus an SEO strategy you’re confident in with some validation around it, and are just looking for extra hands to bring it all to life—an agency is probably the best path to take.

Here’s why:

• You’re not relying on them for their expertise and strategic advice—just implementation
• They have the physical resources needed to execute work as an extension of your team
• Economies of scale are in play—implementation work will likely cost less than if you were to hire a team to do it all in-house

The key here being a VALIDATED strategy.

If you haven’t proven the strategy works yet, don’t scale it with an agency. Prove it first, THEN pour gas on the fire.

Red flags to watch for with SEO agencies

Even when an SEO agency is the right fit, not all agencies in the SEO industry are created equal. Watch for these warning signs:

• 12-month contracts with buyout clauses: If they need to lock you in for a year, ask yourself why. Good agencies earn your business month-over-month
• Selective reporting: Only showing the wins, never the losses or stalled metrics
• Guaranteed rankings: No legitimate SEO partner can guarantee specific rankings (Google doesn’t work that way)
• Unverifiable case studies: Success stories with no client names, no specifics, no way to verify
• The disappearing A-team: Senior strategists on the sales call, then you never see them again after signing

If you spot multiple red flags, keep shopping.

When an SEO consultant is best

If you’re in the opposite situation—no senior-level SEO in-house, not confident in your strategy, or still figuring out what the right approach even looks like—an SEO consultant is the better fit.

Here’s why an SEO consultancy makes sense:

• You need strategic guidance first: Before you execute at scale, you need to know what to execute and why it matters
• No one internally can validate if the plan is solid: Without senior SEO expertise in-house, you need an external expert to reality-check the approach
• Your business goals need translation into SEO strategy: Consultants help bridge the gap between “we want to grow” and “here’s exactly what we should do”
• You’re not ready to scale yet: Scaling an unproven strategy wastes money fast

A good SEO consultant sets the strategic direction that determines whether your later execution (agency or in-house) actually works.

Questions to ask when evaluating consultants

Not all SEO consultants operate the same way. Ask these questions to figure out if their model actually fits your needs:

1. How many clients do you work with at once?

If they’re juggling 15-20 clients, you’re getting a fraction of their attention. Look for consultants who cap their client load intentionally. For example, with Backstage SEO, I only work with 4-6 clients at a time—that’s by design, not accident. It’s the only way to be both strategic and hands-on.

2. What does “hands-on” actually mean in your model?

Some consultants only do strategy. Others do strategy plus execution. Neither is wrong, but make sure their answer matches what you need. If you want someone to write content and implement recommendations, confirm they actually do that work—don’t assume.

3. Can I see examples of actual work you’ve done?

Not case studies with big traffic numbers. Actual deliverables. Content they’ve written, strategies they’ve built, audits they’ve produced. This tells you if their quality bar matches yours, and if their expertise is real or just good marketing.

4. What metrics do you optimize for?

If they only mention rankings and traffic, that’s a red flag. You want an SEO consultant focused on pipeline, revenue, and conversions—the stuff that actually matters for your business. SEO services should drive business outcomes, not just move numbers on a dashboard.

5. How do you handle reporting?

Good consultants show you everything. Green AND red. What’s working, what’s not, and why. Bad consultants cherry-pick wins and bury the rest. If they’re only showing you the good stuff, they’re hiding something.

When you may need both (consultant + agency)

Sometimes the answer to agency vs consultant question is actually both.

You’ve worked with a consultant to build and validate your strategy. You’re seeing traction—rankings improving, traffic growing, leads coming in. Now you want to scale production to capitalize on the momentum… but the consultant doesn’t have capacity to produce 20-30 pieces of content per month.

The solution here can be:

Keep the consultant for strategic direction and let them oversee an agency that handles high-volume execution. The consultant remains your strategic partner and quality control layer, while the agency becomes your production engine—reviewing output and course-correcting as needed.

This is actually how a few of the larger clients I’ve worked with at Backstage SEO operate.

• I handle strategy, planning and optimization
• I produce content for the first few assets (usually the 10-20 highest-value topics we know we need to nail)
• Then they tap a content agency or external writer for additional volume

I keep a finger on the pulse as content gets produced to make sure it stays on-strategy.

When the right choice is actually neither (yet at least)

Sometimes the honest answer is you’re not ready for either one.

You shouldn’t invest in SEO services if:

• You don’t have product-market fit yet. SEO can’t fix a product nobody wants. Find PMF first (or at least get close to it), then invest in distribution channels like search.
• You can’t track or measure results properly. If your analytics are broken or you don’t know your conversion rates, you can’t tell if SEO is working. Fix measurement first before investing into search to bring in qualified traffic.
• You’re not willing to commit at least 6 months. It’s cliche, but the reality is SEO takes time to reach the big wins you’re chasing. Yes, there’ll often be plenty of quick wins early on, but search is ultimately a marathon, not a sprint. If you need leads next month, spend money on paid ads instead.
• You don’t have anyone internal to coordinate with the external partner. Someone needs to provide product info, review content, and give feedback. If everyone’s too busy, nothing will ship—no matter how good your SEO consultant or agency is.

Get the foundation right first, then come back to the agency vs consultant question when your business and company are actually ready.

… Or you can get the best of both worlds with the boutique SEO consultancy model

There’s actually a third option that combines the best parts of both—”boutique” consulting companies that offer strategy AND execution, but without the typical big agency drawbacks.

Strategy & execution without agency overhead

This is the model I run at Backstage SEO (and I know a few other consultants operate similarly).

You get senior-level strategic thinking combined with done-for-you content creation. For Backstage in particular, I’m personally steering the strategy and also producing the content—no junior writers, overseas VA’s, account managers, or secret handoffs.

Pricing typically falls in the $5K-$15K/month range instead of $15K-$30K+ like you’d get with many agencies. Why? Because there’s no big team, no fancy office, and no layers of overhead.

And it’s all month-to-month. If it’s not working, you can walk away, simple as that. This way, the consultant’s incentives are directly aligned with creating positive outcomes every single month (not just during renewal season).

How boutique consultants deliver both

The key is intentionally limiting client load.

For example, I only work with 4-6 clients at a time. That gives me enough hours in the week to be strategic AND hands-on for each client. I’m not trying to juggle 20 clients like some junior account managers are forced to in the agency world.

The typical structure looks something like this:

• Recurring strategic direction and consulting (async or via calls)
• Optimization and experimentation depending on what we’re seeing
• Plus a dedicated amount of content deliverables per month

For example, the “Growth” tier with Backstage SEO typically includes 2x new content pieces and 2x content refreshes each month.

(Fewer assets than a big agency would produce, yes—but each is often going to be far higher quality because I’m handling production myself, not delegating 20 articles/mo to offshore junior writers who only care about hitting their arbtrary word counts.)

When the boutique model makes the most sense

This model is the better fit if you’re in the $3M-$50M ARR range. You need professional SEO support but can’t justify $200K+ for a full-time senior hire plus content production costs. You want strategy AND execution but don’t need (or want to pay for) agency-level volume.

It’s also great if you’ve been burned by agencies before:

• No more 282 cycle bait-and-switch
• No more account manager telephone game
• No more paying for infrastructure you don’t need

Again, the trade-off is output volume.

Most boutique SEO consultancies can’t produce 40+ pieces of content per month like an agency can.

But honestly? Most mid-sized B2B SaaS businesses don’t need 40 pieces of content every month. You just need to cover the most important topics that your prospects care about (and that signal high intent).

If that means we focus on producing 20-30 truly great content assets over the course of a year instead—great. Chances are, that’s going to contribute far more to moving your business goals forward than 300 watered-down articles on mostly-irrelevant topics.

Wrapping up…

So, agency or consultant?

Here’s the short version, based on everything we’ve covered:

• If you have validated strategy and senior SEO expertise in-house: Agency likely makes the most sense to scale execution
• If you don’t have strategy figured out yet: Consultant first to set direction, potentially agency later to scale execution (but don’t rush your way to that point)
• If you want both strategy and execution (albeit at lower volumes) without agency overhead: Find a boutique SEO consultancy (ahem, like Backstage SEO)

The bottom line is this:

Sequencing matters.

Get the strategy right first, then scale execution. If you try to speed through the upfront work, you’ll be scaling a completely broken system that’ll just need to be torn down eventually anyway.
