SEO Agency Pricing for B2B SaaS: What Retainers Cost and What You Get

A few years ago, I could price an SEO retainer on the back of a napkin.

One human-written article was around €500. One good backlink, another €500. A designed and developed landing page, roughly the same. You added up the pieces, multiplied by the months, and that was the proposal. It worked because every piece of work took a predictable number of hours, and hours were what you were really paying for.

"Before, agency pricing was really easy. You could truly plan everything, because you could calculate how many hours everything takes." – Romana Kuts, Founder at SaaStorm

That doesn't work anymore. Today we run Claude, AirOps workflows and MCP connections, and we pay for tokens and APIs on top of people's time. The same budget can now produce twice the output – or the same output, done far more thoroughly. Which makes the most common question on our sales calls harder to answer, and more important to answer well: what does an SEO agency actually cost, and what should I get for it?

Pricing comes up on almost every discovery call we run with B2B SaaS teams, from pre-seed to Series C. So in this guide I'll walk you through it the way I'd explain it on a call: what the market charges, why the old pricing models broke, how agencies price work now, what our own numbers look like, and how to tell whether the quote in front of you is fair.

How much does an SEO agency cost in 2027?

Let's start with the number everyone wants. The honest answer is a range, because "SEO" covers everything from a local plumber's Google Business Profile to a full content engine for a Series B SaaS company. The price of SEO services depends far more on who you hire and what they actually do than on the word "SEO" in the proposal. Local SEO for one city and national SEO for a software category are completely different SEO campaigns, and they're priced that way.

Here's roughly what SEO services cost in the UK and across Europe, based on published pricing data and the quotes our prospects share with us:

For context, a UK study of 45 published SEO prices by Whito found a median of roughly £800 a month, with established agencies pricing between £1,500 and £5,000+. In Ahrefs' survey of 439 SEO providers, the most common answer was $501–$1,000 a month, with agencies averaging an estimated $3,200 – noticeably more than freelancers. Those averages are pulled down by small business and local SEO packages, which is why B2B SaaS quotes from specialist SEO companies tend to land higher. The same is true for SEO freelancers: a great one can be excellent value, but one person can only carry so much monthly SEO work.

So why do B2B SaaS teams usually pay more than the average SEO cost? Because the work is different. You're not trying to rank a single service page in one city. You're competing nationally or internationally, often in categories where your competitors have bigger domains, and your buyers are researching across Google, ChatGPT, review sites and Reddit before they ever book a demo. That takes deep keyword research, a real content strategy, expert content, technical SEO, link building to build domain authority and, increasingly, answer engine optimisation for AI search, Google AI Overviews and ChatGPT. Search engines and AI assistants both have to trust you, and earning that trust is ongoing optimisation, not a one-off SEO project.

But the monthly number on its own hides the bigger story. What you get for €6,000 a month in 2027 looks very different from what you got for the same money three years ago – and that's where most SEO pricing guides stop being useful.

Why the old price-per-article model broke

For years, SEO pricing was basically a time calculation dressed up as a package. To understand why that's changing, it helps to look at what those hours used to buy, what AI workflows changed, and the new costs agencies now carry that didn't exist before.

What hours used to buy

In the old model, every deliverable had a fairly fixed effort. A researched, human-written article took a writer two to three working days. A landing page needed a UI/UX designer and a developer for most of a week. A backlink needed outreach, negotiation and a placement. Agencies and SEO professionals knew these hours, so they could put a price on each piece, and you could compare one SEO provider's price list against another's line by line.

That's why "€500 per article, €500 per link" felt so clear. It was clear. It was also only fair as long as the hours stayed the same.

What AI workflows changed

Then the hours changed. With well-built AirOps and Claude workflows, research, outlining, first drafts, internal linking and on-page optimisation can be done in a fraction of the time – with a human editor still checking every piece. The same goes for design and development. A designer and developer still need to be involved early, to build the components and set the standards. But once that system exists, a lot of the page building can move to Claude Design and Claude Code, built on top of what they created.

The result is that output per euro has roughly doubled for some types of work. Where 20 articles a month used to mean a €10,000 monthly retainer, you can now get 20 AI-assisted articles inside a budget of around €5,000.

To make that concrete, here's one of our own clients. They pay us €10,000 a month. In one month, we delivered 20 articles. In another month, on the same retainer, we delivered 55 articles plus 10 new product pages. Nothing about the price changed – what changed was the type of work and how much of it could run through our workflows.

The new costs agencies carry

None of this means SEO got free. Agencies now pay for things that weren't on the invoice three years ago: tokens, API access, MCP connections, AI tools and SEO tools that each run into hundreds or thousands of euros a month. Our own tool stack, for example, includes Semrush, AirOps, Scrunch, Surfer, Clay and ClickUp, and costs around €2,000 a month before anyone does any work.

So the cost of SEO hasn't simply gone down, and SEO pricing hasn't simply dropped. It's moved. Less of your budget pays for hours, and more pays for systems, tools and the people who know how to run them well. That shift is exactly why you're now seeing very different SEO pricing models in agency quotes.

The SEO pricing models you'll see in agency quotes

When you collect three or four proposals, you'll notice they don't price the same way. That's not always a red flag – different pricing models suit different kinds of work. The trick is knowing which model fits which work, so you can spot when an agency is charging human prices for machine-speed output, or the other way round.

Output-based pricing: per article, per link, per page

This is the classic model, and for some work it's still the fairest one. Human-written content is the best example. When a real writer researches your topic, interviews your experts and spends 15 to 20 hours on a piece, a price per article makes perfect sense – the effort hasn't really changed.

"Human-written content still stays nicely priced." – Romana Kuts

The same goes for high-DR backlinks and digital PR, where each placement has a clear cost. You know exactly what you're buying, and that clarity is worth a lot.

Effort-based pricing: AI content engineering

AI-assisted content is where output-based pricing stops working. If an article is produced with an AirOps or Claude workflow and then reviewed by an editor, charging the same as a fully human-written article doesn't hold up.

"It just doesn't make sense to charge €700 per article that was created with an AirOps workflow." – Romana Kuts

Instead, agencies price the effort: setting up and maintaining the workflow, feeding it your brand voice and product knowledge, and editing what it produces. In practice that sounds like "for €2,000 a month, we'll produce between 7 and 10 AI-assisted articles". You're paying for a system that keeps producing, not a fixed number of hours per piece.

Retainers built from a forecast

The most useful model for B2B SaaS combines the two above inside a monthly retainer – but sizes it from your revenue goals rather than a price list. The agency works out how much pipeline you need, what traffic and content that requires, and which mix of human-written content, AI-assisted content, optimisations and links gets you there. Then it prices that plan.

You still get clarity on outputs – X articles, X optimisations, X links – but the number of each comes from the forecast, not from a package tier someone designed years ago.

Hourly, project and fixed monthly fee pricing

Hourly rates, one-off projects and simple packages with a fixed monthly fee still have their place, mostly for audits, migrations, technical fixes and consulting. UK freelancers typically charge £30–£150 an hour depending on experience, and strategy consultants more. For ongoing SEO, though, hourly billing rewards slow work rather than results, so we rarely recommend it for B2B SaaS.

Knowing the models is half of it. The other half is seeing what those models look like with real numbers attached – so here are ours.

What you actually get for the money: our pricing as an example

We publish our prices on our pricing page, because I think B2B SaaS buyers deserve to compare quotes properly. So rather than talk in averages, here's how a real B2B SaaS SEO agency prices its work in 2027, and what's behind each number.

Everything starts with a 10-day discovery phase at €4,000, one-time. In those ten days we audit your website and content, map your keyword opportunities into topic clusters, take an LLM visibility snapshot, research competitors and build a revenue forecast. You get a 6-month plan with three monthly budget options. If you decide not to continue with us, you keep everything.

From there, the monthly budget is built from the pieces your plan needs:

On top of that comes strategy, reporting and coordination, and our packages start from €6,500 a month. Design, development and paid ads are scoped separately, because they vary too much to put on a price list.

Here's what that can look like in practice. Say you want to publish 20 articles a month. If all 20 are human-written, you're looking at €12,000–€14,000 a month just for content. If you mix four human-written articles for your most important bottom-of-funnel topics with 16 AI-assisted articles for informational topics, the same 20 articles land at around €7,000 a month including strategy – roughly half – and your best topics still get the full human treatment.

That's the real advantage of a mixed model: you stop paying human prices for every piece, without giving up human quality where it counts. It's how Asora turned a €79,250 investment into €20.15M in qualified pipeline in nine months, with 56 human-written articles, 12 AI-assisted articles and 11 templates.

Of course, our pricing is only one example. The more useful question is how you judge any quote that lands in your inbox.

How to tell if an SEO agency quote is fair

Comparing SEO packages and SEO services pricing on price alone is how teams end up with cheap SEO that never moves pipeline, or expensive SEO that mostly pays for overheads. A fair quote isn't necessarily the lowest one. It's the one where you understand exactly what each euro buys, and why.

"When you're looking at an agency, look at what tools they are using and how they work." – Romana Kuts

Start by asking how the work actually gets done. Which tools do they use? Which parts are human-written, and which are AI-assisted? Who edits the AI output? An agency that can't answer these questions clearly is either hiding its process or doesn't have one. Then ask whether they'll build you a forecast before you commit to a monthly budget – and how that forecast connects their outputs to your pipeline.

While you're reading the proposal, watch for these red flags:

• No discovery phase. If an agency can quote a monthly retainer before looking at your site, your competitors and your goals, the plan isn't built for you. A "free SEO audit" that's really a sales deck doesn't count.
• AI content at human prices. If the per-article price is the same for everything, ask how each piece is produced.
• Article counts with no strategy. "10 articles a month" tells you nothing about which topics, for which buyers, at which funnel stage.
• Guaranteed rankings. Nobody controls Google or ChatGPT. Guarantees usually mean black hat SEO tactics or vanity keywords.
• Long lock-ins. A 12-month contract protects the agency, not you. Look for a short pilot and a reasonable notice period.
• Traffic-only reporting. If reports stop at Google Analytics traffic, online visibility and organic rankings, nobody is accountable for MQLs, SQLs and revenue.

A quote that passes these checks is usually a fair one. But fairness is only half the decision. The other half is whether the budget makes sense for your business at all.

How to set your SEO budget: start from ARR, not a price list

Most teams set their SEO budget backwards. They pick a number that feels affordable, then ask what it buys. It works much better the other way round: start from your revenue goal and work back to the SEO investment it needs.

That's how we build every forecast. We take your ARR target and your average contract value, work out how many new customers you need from organic search, and how many SQLs and MQLs that requires at your conversion rates. From there we estimate the traffic and AI visibility needed to generate those leads, and the content, optimisations and links needed to get there. Only then do we put a price on it.

The goal is simple: a plan for your SEO efforts that's forecast to be ROI-positive before you spend a euro on execution. If the numbers don't work at a budget you're comfortable with, it's far better to know that during discovery than six months into a monthly retainer. And if a smaller budget is all you have right now, a good agency will tell you what that budget can realistically deliver, and where to focus it first.

The bottom line

SEO agency pricing in 2027 is less about the monthly number and more about what sits behind it. Search engine optimisation hasn't become cheap or expensive – the work behind it has changed. Human-written content still costs what it costs, because good writers still need time. AI-assisted work should be priced by effort, because it no longer takes the same hours. And the right monthly budget is the one that comes out of a forecast, not a package tier.

So when you compare quotes, compare the process, the tools and the forecast – not just the price. That's what we try to make easy, with transparent prices and a plan that has to make sense for your pipeline first.
