"And SEO, how much does that cost?" It is probably the question I hear most often, right after the price of the website itself. And it is the one that gets the most evasive answers on the market: "it depends", "on quotation", "from", without ever explaining what it depends on or what exactly you are buying.
I am an independent web developer in Hannut, Belgium, and search engine optimisation is part of my daily work: every website I deliver ships with its SEO foundation, and I support Walloon businesses that want to go further. What I offer you here is the answer I wish my first clients had been able to find: frank, structured, with no magic promises.
Seven truths, in the order they matter. By the end of this article you will know how to read an SEO quote, spot the dubious offers, and decide what you delegate and what you do yourself. If local visibility is your main concern, keep my complete guide to local SEO in Wallonia within reach: it details the method whose building blocks we are about to put a price on.
Truth 1: SEO is not a product, it is a set of worksites
First misunderstanding to clear up: you do not buy "SEO" the way you buy a printer. Behind that word hide very different worksites, with very different costs. When a quote announces "search engine optimisation: €500" without any breakdown, it tells you nothing at all.
The technical foundation first: the site's structure, its speed, its tags, its structured data, its sitemap. That is developer work, done once and then maintained. With me, it is included in every website I build, not sold as an option.
Content next: the service pages, the local pages, the articles that answer your customers' searches. That is writing and strategy work, recurring by nature, and it is what makes the lasting difference.
Local SEO: the Google Business Profile listing, reviews, the consistency of your contact details, directories. A mix of initial configuration and good monthly habits.
Authority, finally: earning links from other credible websites, the local press, your partners. It is the longest worksite, and the hardest to industrialise honestly.
The reflex to have in front of any quote
Always ask for the breakdown: how much for the technical work, how much for content, how much for local, how much for links. A serious provider answers in two minutes. A fog merchant changes the subject.
Truth 2: billing models matter more than the amounts
In French-speaking Belgium you will come across three ways of billing SEO, and each one tells you something about the provider.
The monthly retainer is the most widespread among agencies: a subscription covering a volume of hours or deliverables per month. It makes sense for continuous groundwork, provided the deliverables are named in black and white: so many pages optimised, so many pieces of content produced, a readable monthly report. The classic trap: the subscription that keeps being debited while the actual work stopped in month three.
The one-off project: an audit, a complete optimisation, a migration. Fixed price, fixed scope, clear end. It is the format I prefer for getting started, because it leaves you free afterwards.
The hourly rate, finally, mostly among freelancers, for targeted interventions. Transparent by nature, but hard to budget for a large worksite.
As for the amounts: the market runs from a few hundred euros for an audit or a one-off optimisation to several thousand euros per month in highly competitive sectors. I will not give you falsely precise averages: they vary too much with the area, the trade and the ambition. The next truth gives you the real factors.
Truth 3: local SEO costs less and pays back faster
Good news if you run a shop, a trade business or a professional practice: you do not need national SEO. Being visible across "the whole of Belgium" is useless if your customers come from your municipality and the neighbouring villages. And aiming local completely changes the financial equation.
Competition is weaker there: you are not fighting over-equipped national websites, but the businesses in your area, many of which have never worked on their online presence seriously. The effort needed to emerge is therefore more reasonable, and results arrive sooner.
Part of the local levers is even free in money, if not in time: the Google listing, customer reviews, the consistency of your contact details. I have summarised the concrete moves in my 9 local SEO actions for Wallonia, ranked by priority: it is the best starting point before spending anything at all.
Concretely, for a Walloon independent, a well-spent local budget concentrates on three items: a technically clean website, local pages for your important municipalities, and a customer review routine. The rest can wait.
Truth 4: four factors multiply the bill by up to five
Why does your neighbour the florist pay three times less than your colleague the lawyer? Because four factors determine the effort required, and therefore the price.
The competition in your sector first. Some trades are digital battlefields: legal, real estate, credit, renovation in the big cities. Others are quiet meadows where a serious presence is enough to dominate. Type your own keywords and look at who occupies the first page: heavyweights or amateur websites?
The state of your website next. A recent, fast, well-built site only needs fine tuning. An old, slow site built on a bloated theme sometimes needs a rebuild before SEO is even worth discussing. That is exactly the link between the price of SEO and the price of a website in Belgium: a good new site often costs less than a prolonged resuscitation.
The existing content: if your pages are empty or duplicated, everything remains to be written, and copywriting is the heaviest item in any serious SEO budget.
The target area, finally: being found in a rural municipality, in a district, or across an entire province are three different ambitions. My clients around Liège know it well: the metropolitan area is more contested than the Hesbaye countryside, and the work plan adapts accordingly.
What a serious SEO service contains, item by item
So that you can compare quotes that are actually comparable, here is what a complete engagement really contains, in the chronological order of a well-run project.
The initial audit opens the ball: technical analysis of the site, inventory of the existing content, examination of the Google listing and directories, study of your customers' real searches, review of the local competition. It is the X-ray before the treatment. Its quality conditions everything else: a rushed audit produces a work plan that misses the point.
The technical upgrade next: fixing the errors found, loading speed, mobile adaptation, tags and structured data, sitemap and Search Console. Developer work, concentrated over a few days, which is not redone every month.
The content worksite follows: rewriting the service pages, creating the local pages, then regularly producing articles or pages that answer your customers' questions. It is the most hour-hungry item, and the one where quality is visible to the naked eye: read what the provider has written for other clients before signing.
Local SEO in parallel: optimising the Google listing, a review strategy, consistent contact details, useful Belgian directories. Then authority: gradually earning credible links, local press, partners, sector directories.
And as a running thread, the follow-up: a readable periodic report showing positions, traffic, and above all the enquiries generated. If one item on this list is missing from the quote without explanation, ask the question.
Truth 5: the too-good offers are the most expensive ones
Let us talk about the proposals you already receive by phone and email. "First position on Google guaranteed." "Complete SEO for €49 per month." "Your website is not compliant, we can fix it today." I receive them myself, which says it all.
The guaranteed position first: nobody controls Google's ranking. Nobody. Guaranteeing a precise position is either ignorance or a commercial lie. The only honest commitments concern the work delivered and progress indicators, never an exact spot.
The rock-bottom retainer next: SEO requires qualified human hours. A bargain subscription finances, at best, an automated monthly report nobody reads; at worst, toxic techniques: links bought in bulk on site farms, content generated in series without review. These practices can earn your website lasting penalties.
And that is where the "cheap" offer becomes the most expensive: cleaning up a toxic link profile or recovering from a penalty costs far more than doing things properly from the start. I have rescued websites in that state: the repair budget exceeds, every single time, the serious engagement that should have been chosen at the beginning.
Three questions that unmask a dubious seller
Who actually does the work, and where? Which precise deliverables each month? What happens if I stop? If the answers are vague, if everything is "confidential" or "automated", walk away, whatever the price.
Truth 6: part of SEO is free, if you put in your time
I may be working against my own interests by writing this, but it is the truth: a significant part of local SEO requires no budget at all, only method and regularity.
Your Google Business Profile listing is free: creating it, filling it in completely, publishing photos and updates on it, all of that is within your reach. Asking every satisfied customer for a review costs nothing: it is a reflex to install, not a service to buy. Checking that your name, address and phone number are identical everywhere online is one evening of meticulous work.
Writing a page that properly answers one of your customers' frequent questions is more demanding, but a business owner who knows their trade and agrees to write the way they speak manages very well. Your authentic texts will often beat the generic prose of a rushed copywriter who knows neither your trade nor your region.
What is hard to do yourself, conversely: the site's technical foundation, the page architecture, the structured data, the diagnosis of invisible problems. That is a profession. The smart split for a small budget: you take the day-to-day, a professional lays the foundations and guides you. That is exactly the logic of my engagements, and my public pricing reflects this philosophy: the SEO foundation is included in every website I build, from €380 for a showcase site.
Three profiles, three intelligent ways to spend
To make all this concrete, here is how I structure the thinking for the three profiles I meet most often in Wallonia.
The neighbourhood business first: bakery, hair salon, restaurant, shop. Its customers live within a few kilometres. Its absolute priority: an impeccable, living Google listing, regular reviews, a fast showcase website with up-to-date practical information. The bulk of the budget goes into a good starting website; the day-to-day is handled in-house. A heavy retainer would be money badly placed.
The tradesman or mobile independent next: electrician, gardener, coach, therapist. They work across several municipalities, and competition varies by area. Their priority: polished local pages for their profitable municipalities, on top of the foundation. It is the profile where a few well-built pages genuinely change how often the phone rings, and where a one-off structuring engagement pays off the most.
E-commerce, finally: an online store sells beyond its region, and the competition is national or even international. Here, content and authority weigh heavily, the work is continuous by nature, and a recurring engagement is easier to justify. It is the profile where budgets climb, and where calculating the cost per customer becomes vital before committing.
Truth 7: the right calculation is cost per customer, not the price of the service
Last truth, the most important one: an SEO price is never judged in the absolute. It is judged against what a customer is worth to you.
Do the maths yourself, with your real numbers. What is a new customer worth to your business? Not just their first invoice: their loyalty, their recommendations, their repeat purchases. A garage customer comes back every year. A notary's client brings in two more. You know these amounts better than any consultant.
Now ask the question differently: how many new customers per month would it take to pay back a given SEO budget? Often, the answer is surprisingly low: one or two additional customers cover the investment. That calculation, and it alone, tells you whether a quote is expensive.
This reasoning also changes how you look at time. A twelve-month engagement seems expensive seen as an expense; seen as the acquisition of an asset that will produce customers for years, it compares to buying a van or a machine. You are not buying Google positions: you are buying a durable acquisition channel that belongs to you, and whose value adds up instead of evaporating each month.
One last safeguard for this calculation: actually measure. Without tracking of calls and forms, you will never know whether the investment is producing. Demand that tracking from the first month of any engagement: it is what turns a battle of opinions into a management decision.
It is also what separates SEO from advertising. Google Ads produces enquiries as long as you pay, then stops dead with the budget. Organic SEO builds more slowly, but the positions earned keep working without a monthly invoice. The two actually combine very well at the start: I detailed that strategy in Google Ads or SEO on a small budget.
Before signing: the meeting checklist
You have shortlisted one or two providers? Here is the framework I recommend for the scoping meeting, whether it takes place with me or with a colleague. It fits in six questions and a quarter of an hour.
What will you do in the first month, concretely? The answer must describe actions, not concepts. Which keywords will you work on, and why those? The provider must be able to link every keyword to a real intention of your customers. Who writes the content, and can I review it before publication? You remain responsible for what your brand says.
How will you measure results, and on which indicators? Expect calls, quote requests, sales, not just positions. What belongs to me if we stop? The content, the accounts, the data must stay with you. And finally: what can I do myself to reduce the bill? An honest provider will give you a real list, not an embarrassed silence.
Take notes during the answers. The difference between a professional and a salesman is not visible on the brochure: you hear it in the precision of the answers to these six questions.
The vocabulary of SEO quotes, translated into plain language
One last service before concluding: the small glossary that will keep you from signing without understanding. SEO quotes love jargon, so here it is translated.
"On-page optimisation": the work on your own pages, texts, tags, structure. "Off-page optimisation" or "link building": the links coming from other websites to yours. "Technical audit": checking the site's machinery, speed, indexing, errors. "Keyword research": the study of what your customers actually type into Google. "Structured data": the invisible labels that describe your business to search engines.
"Tracking" or "conversion tracking": measuring what the website produces, calls, forms, sales. "Local SEO": everything related to the map, the Google listing and nearby searches. "Evergreen content": pages that stay useful over time, as opposed to news items.
None of these terms is a dirty word, but each must correspond to identifiable hours of work. A quote that piles up jargon without deliverables is a restaurant menu without prices: you will discover the bill too late.
What to remember from this whole article
Demand a quote broken down item by item. Flee position guarantees and opaque retainers. Aim local before national. Do yourself what is a matter of habit, delegate what is a matter of profession. And judge every price with a single number in mind: what a customer is worth to you.
How I work, and what it costs with me
Since this article promises transparency, let us end with mine. My conviction, forged on the ground in Wallonia: the majority of local independents and businesses here do not need a heavy SEO retainer. They need a well-built website, local SEO set up seriously, and good habits.
Concretely: every website I build includes the complete SEO foundation, clean structure, tags, speed, structured data, sitemap, Google registration. No hidden option, it is included in the price of the site. For an existing website, I always start with a free diagnosis: I look at your site, your listing, your competition, and I tell you frankly what is worth doing, what can wait, and what you can do yourself.
Then, two formats depending on the need: a one-off intervention with a fixed scope (complete optimisation, local pages, rebuild of the foundation), or light ongoing support for content and follow-up. Always with a quote detailed item by item, sent within 24 hours, and never a commitment that traps you.
My final advice, whether you work with me or with someone else: demand transparency, refuse magic guarantees, do the cost-per-customer calculation, and start with local. SEO is neither a lottery nor a compulsory monthly tax: it is an investment you can reason about, like every other investment in your business.
