SEO or Google Ads: where should your budget go?
Short answer: start with Google Ads if you want to find out quickly whether there’s demand for what you sell, because you’ll have data within a week. Invest in SEO if, twelve months from now, you no longer want to depend on your ad budget. If your budget is limited and you have to choose, the order is usually: Ads first, to learn which search terms bring in customers, then SEO to win exactly those terms organically. After a year, most of our clients sit at roughly seventy per cent SEO and thirty per cent Ads.
It’s the classic question with every marketing budget. Do you pay for visitors, or do you invest to get them for free?
That contrast doesn’t quite hold, because SEO costs money too. The difference lies in what you’re left with when you stop.
The fundamental difference
Switch off Google Ads and your traffic disappears the next day. Completely. Stop doing SEO and your rankings slip slowly over months or years, but the pages you created stay online and keep bringing in visitors.
You rent Ads. You build SEO.
Side by side
| Google Ads | SEO | |
|---|---|---|
| First results | one to seven days | three to twelve months |
| What you pay | per click, ongoing | one-off or monthly, for the work |
| Does it stop when you stop | yes, immediately | no, it fades slowly |
| Predictability | high: you buy impressions | low: you depend on the algorithm |
| Testing messages | excellent | slow |
| Cost per visitor over three years | stays the same or rises | falls as you add more pages |
| Visitor trust | lower, people can see it’s an ad | higher |
| Cited by AI search engines | no | yes |
| Suited to urgent demand | very | moderately |
That second-to-last row is becoming more important all the time. When someone asks ChatGPT, Perplexity or Google AI Overviews a question, the answer cites content pages. Ads never appear there. If you want to be mentioned in those answers, you can’t buy your way in.
When to start with Google Ads
Choose Ads as your starting point in these cases.
You’re launching something new and you don’t know whether there’s demand for it. Within a week you’ll see whether people search for it, what they click on and whether they convert. It’s the cheapest market validation there is.
You have an urgent need. A fully booked schedule in November is worth nothing if you needed the work in September.
You sell something people actively search for at the moment they need it. A plumber for a leak, a lawyer for a dispute, a breakdown service by the roadside. In those markets, whoever sits at the top at that exact moment wins.
You have seasonal peaks. Advertising in the weeks that count is more efficient than producing content all year round for two busy months.
Our guide prices for paid advertising: Google Ads setup from €450, management €650 to €850 a month. On top of that comes your own ad budget, which you pay directly to Google. Below roughly €500 a month in ad spend, it becomes hard to collect enough data to optimise.
When to start with SEO
Choose SEO as your starting point in these cases.
You have a long sales cycle in which people do their research first. With B2B services, construction projects or software, buyers start asking a search engine questions months before they decide. If you’re already answering them at that stage, you’re at the front of the queue when things get serious.
Your competitors all advertise and click prices are high. In sectors where a single click costs several euros, organic traffic quickly becomes the cheapest channel.
You want to be found in AI search engines. Only content gets you there.
You have time. If you only need to be running at full speed a year from now, you’re better off building now than renting later.
Our guide prices for SEO and GEO: SEO Advanced, including settings for AI search engines, hreflang and schema, from €550. An ongoing content approach costs between €600 and €1,000 a month.
The split that works in practice
Most businesses do better with both, but not in equal parts and not from day one.
Months one to three. The focus is on Ads. You learn which search terms bring in enquiries, as opposed to just clicks. Meanwhile, you sort out the technical SEO basics: speed, structure, schema, sitemap. Which CMS you use partly determines how much work that is.
Months four to nine. You shift towards content. You now know which terms convert, so you create pages on exactly those topics. Ads keep running, but you cut the search terms that deliver nothing.
Month ten onwards. Organic traffic takes over a growing share. You keep Ads for the search terms where you won’t win organically any time soon, and for peaks.
The end goal is to reach the point where Ads are optional, even if you keep running them.
What people get wrong
SEO isn’t free. You pay in working hours and in content. People who think it’s free don’t do the work, then wonder a year later why nothing is happening.
Ads aren’t expensive when they work. Spending €1,500 a month to bring in €5,000 in revenue doesn’t count as a cost. The real problem is measurement: if you don’t know what an enquiry is worth, you can’t judge whether it pays off.
You can’t buy the top spot with SEO. Agencies that guarantee rankings are promising something nobody controls.
Stopping Ads because “SEO will take over” is almost always premature. Build up your organic traffic first, and only then scale back the budget.
Frequently asked questions
What does SEO cost per month in Belgium?
For an SME, an ongoing approach costs roughly between €600 and €1,000 a month. With us, one-off technical optimisation starts from €550. Anything below that is usually too little to create real content.
How long does SEO take to work?
Expect three to six months for the first movement and nine to twelve months for competitive search terms. A new domain takes longer than an existing site with some history.
Is Google Ads worth it on a small budget?
Below roughly €500 a month in ad spend, it gets difficult. You get too few clicks to learn what works, and you pay management fees on too small an amount. With a small budget, you’re better off choosing one tightly defined campaign than going for broad visibility.
Does SEO also help with ChatGPT and Perplexity?
Yes, and that has become one of the strongest arguments for it. AI search engines pull their answers from content pages. Clear structure, concrete figures and real answers to real questions are what get you cited. Ads don’t feature there.
Can I do both on a limited budget?
Yes, but not both at full strength at the same time. Start with three months of Ads to learn which terms count, then turn that insight into content. That’s more efficient than doing both half-heartedly.
In short
Google Ads buys you time. SEO buys you independence. With urgent demand or a new launch, start with Ads. With a long sales cycle or expensive clicks, start with SEO. And in most cases you do both, with the emphasis shifting from paid to organic over the course of the year.
Who will do this work is the next question. That’s what Freelancer, agency or in-house is about.
