What Does Outsourcing SEO Cost? Prices and How to Choose an Agency

You know you need to be easier to find on Google, but you can't manage it yourself and the prices agencies quote are all over the place. One asks €300 a month, another €5,000, and both promise the same thing. How is that possible, and what is a fair price? In this article we explain what outsourcing SEO costs, which pricing models exist, where the budget goes and how to choose an SEO agency that delivers real results rather than pretty reports.

What does outsourcing SEO cost? The short answer

For an average Dutch SME, outsourcing SEO costs roughly between €500 and €2,500 a month. The broad market range runs from around €300 a month for light-touch work to €5,000 or more for competitive industries.

On top of that, some agencies charge a one-off start-up budget for research and technical improvements, often somewhere between €900 and €6,000. The final price depends on your industry, your competition, the state of your website and your ambitions.

That spread feels unsatisfying, but it makes sense once you understand how SEO is priced. We'll go into that below.

The three pricing models for SEO

SEO agencies charge in three ways. The model you come across already says something about how a provider works.

Monthly retainer

By far the majority of agencies work with a fixed monthly fee. You pay for ongoing work: technical improvements, content, link building and analysis. This suits SEO, because it isn't a one-off project but a process that builds results month after month. For SMEs, a retainer like this usually sits between €500 and €2,000 a month.

Hourly rate

Some specialists and freelancers charge by the hour. In 2026, rates range between €80 and €200 an hour, depending on experience. This works well for clearly defined jobs, such as a one-off audit or advice, but is less suited to long-term collaboration, because you end up managing hours rather than results.

Project price

With a fixed project price, you agree an amount for a clearly defined outcome, such as a technical SEO clean-up or optimising a set number of pages. Handy for a well-scoped assignment, but SEO as a whole can rarely be bought in one go.

What's included in that monthly price?

An SEO retainer isn't a subscription to some secret trick. It's a combination of work that recurs every month:

• Technical SEO. Making sure your site loads quickly, can be indexed properly and has no technical blockers. Read what that involves in our complete guide to technical SEO.
• Keyword research. Finding out what your target audience really searches for and which questions they ask.
• Content. Writing or improving pages and articles that answer those search queries.
• Building authority. Getting other relevant websites to link to you, so Google takes you more seriously.
• Analysis and adjustment. Measuring what works, reporting and adapting the approach.

An agency charging €300 a month can simply do less of these things than one charging €2,000. More expensive isn't always better, but this much is true: little money buys few hours, and SEO simply takes work.

Why prices vary so much

Two businesses can pay completely different prices for SEO, and both can be justified. That comes down to these factors:

• Competition in your industry. Reaching the top in a quiet niche is something else entirely from competing with national players who are all investing in SEO.
• The state of your website. A technically healthy, fast site has a head start. An outdated or slow site needs repair work first.
• The age and authority of your domain. An older domain with a track record gets results faster than a brand-new website.
• Your ambitions. Ranking well locally takes less than wanting to be number one nationally.
• The type of provider. A freelancer, a small agency and a large agency have different cost structures and rates.

A good agency maps out these points before naming a price. If you receive a quote without anyone having so much as looked at your website, be on your guard.

How much budget is realistic?

A common rule of thumb: set aside around 5 to 10 percent of your total marketing budget for SEO. More important than a percentage is the question of what a customer is worth to you. If you deliver services worth thousands of euros, an SEO investment of €1,000 a month pays for itself with just a handful of extra customers a year.

Factor in the payback period too. SEO is an investment that costs money upfront and only delivers later. Most businesses recoup their SEO investment within roughly 8 to 14 months. If you expect profit after three months, you'll be disappointed. If you give it a year, you build something that keeps paying off.

How long does it take for SEO to work?

This is perhaps the most important expectation to get clear upfront. SEO doesn't work like an ad you switch on and off.

The first visible results, such as gains on less competitive search terms, usually appear after 3 to 6 months. Stronger results on the truly valuable keywords often follow after 6 to 12 months. An older domain with existing authority moves faster; a new website has to build that trust first.

An honest agency tells you this upfront and doesn't promise a number-one ranking within a month. If you want a deeper understanding of how to rank higher in a sustainable way, read our article on ranking higher on Google for SMEs.

How do you choose a good SEO agency?

Price is only half the story. A cheap agency that delivers nothing is expensive; a pricier agency that brings in customers is an investment. When choosing, look at:

1. Does the agency ask questions first? A serious provider wants to understand your business, your target audience and your goals before promising anything.
2. Is the approach transparent? You should be able to see what happens each month and why. Vague talk about "the algorithm" is a red flag.
3. Do they report on results, not activity? What matters is visitors, enquiries and revenue, not the number of words written or links placed.
4. Who owns the work? Your website, your content and your accounts must remain yours, even if the partnership ends.
5. Does their expertise match your needs? A local business benefits from local SEO, while another may want to go broader or focus on visibility in AI search engines.
6. Can they show results? Ask for examples of previous clients and, where possible, concrete figures.

Warning signs: steer clear of these

A few things are almost always a sign that you'd do better to keep looking:

• Guarantees of a number-one position. Nobody can guarantee that, because Google decides the rankings.
• Results within a few weeks. That's unrealistic and often points to tricks that will harm you in the long run.
• No insight into what's happening. If you're not allowed to know what work you're paying for, something isn't right.
• Long contracts with no way out. A good agency is confident enough to be judged on results.
• A price without an analysis. A serious quote follows a look at your website and your market.

Frequently asked questions about outsourcing SEO

What does outsourcing SEO cost per month?

For an average SME, a monthly SEO retainer costs between €500 and €2,000. In competitive industries, that can rise to €5,000 or more. The price depends on your competition, the state of your website and your ambitions.

Is outsourcing SEO worth the investment?

For most businesses, yes, provided you give it time. SEO brings in visitors who are actively searching for your product or service. Most businesses recoup their investment within roughly 8 to 14 months, and after that it keeps paying off.

How long does it take before I see results?

Expect 3 to 6 months for the first visible results and 6 to 12 months for stronger positions on valuable keywords. A new domain needs more time than an established website.

Wouldn't I be better off doing SEO myself?

You can certainly handle the basics yourself, but SEO is broad: technical work, content, authority and analysis. Keeping that up alongside your day job for lasting results is hard. That's why many SMEs opt for a combination: you supply the subject knowledge for the content, and the agency handles strategy and execution.

Why do SEO agency prices differ so much?

Because the amount of work per month differs, and because freelancers, small agencies and large agencies charge different rates. A low price usually means few hours. So don't just look at the amount, look at what you get in return.

Conclusion

Outsourcing SEO costs an average SME between €500 and €2,500 a month, with higher outliers in competitive industries. The big price differences are no coincidence: they reflect how much work is done each month and how tough your market is. More important than the lowest price is an agency that listens first, works transparently, focuses on results and gives you realistic expectations about the timeline.
