The verdict in three sentences
With 2,000 EUR/month to allocate in 2026, the right answer is neither all SEO nor all Ads, but a 60/40 mix combining immediate results and a durable asset. Google Ads generates leads from week one at 60-200 EUR each, while SEO takes 4-8 months but drops to 30-80 EUR/lead at maturity and keeps producing even when the budget is cut. SEO is an asset you own; Ads are a traffic rental that stops dead the moment you switch it off.
Cost per lead and time to profitability
The two channels do not move at the same pace. Here is the 2026 ballpark for an Amsterdam B2B SME.
| Criterion | SEO | Google Ads |
|---|---|---|
| Cost per lead (ramp-up) | 150-300 EUR | 60-120 EUR |
| Cost per lead (at maturity) | 30-80 EUR | 80-200 EUR |
| Time to first leads | 4-8 months | 3-7 days |
| Traffic if budget cut | 70-90 % kept 6-12 months | 0 % immediately |
| Cost trend over time | Falls | Rises (bidding) |
| Accounting nature | Asset | Recurring expense |
The crossover usually happens between month 6 and 9: past that point, each euro invested in SEO returns more leads than a euro in Ads.
How to split 2,000 EUR/month
The split depends on your commercial urgency. Here are three scenarios by SME profile.
| Scenario | SEO | Google Ads | For whom |
|---|---|---|---|
| Need leads right now | 600 EUR | 1,400 EUR | Tight cash, launch |
| Recommended balance | 1,200 EUR | 800 EUR | Established SME, 12-month view |
| Asset building | 1,500 EUR | 500 EUR | Strong brand, comfortable margin |
The 60/40 mix favouring SEO (1,200 / 800 EUR) is the recommended balance for most B2B SMEs: Ads feed the pipeline while SEO builds, then you gradually reduce Ads as organic climbs.

Mini case study
Thomas, director of a 22-person industrial maintenance SME in Amsterdam, has 2,000 EUR/month. He adopts the 60/40 mix. The 800 EUR of Ads immediately generate 8-10 leads/month at ~90 EUR. The 1,200 EUR of SEO return nothing for the first 4 months, then rise to 18 leads/month by month 8 at ~65 EUR. At that stage he receives ~27 leads/month for 2,000 EUR, an average cost of ~74 EUR/lead, versus 90 EUR in all-Ads. Over 12 months, SEO has created an asset that keeps producing even if he cuts Ads: an estimated ~9,000 EUR/year saving in ad budget at constant lead volume.
FAQ
Can I start with Ads only? Yes, it is even advisable if you need immediate leads. But launch SEO in parallel as soon as possible: every month of delay pushes back the moment you stop "renting" your traffic.
Does SEO make Ads pointless? No, they are complementary. Ads remain unbeatable for offer launches, seasonal peaks and ultra-competitive queries where SEO is too slow to conquer.
Which channel has the best long-term ROI? SEO, because its cost per lead falls over time and traffic persists. Ads have a stable but capped ROI: cost per lead tends to rise with bidding competition.
How do I measure profitability? Track cost per lead and cost per signed client by channel, not just traffic. A 90 EUR Ads lead that signs at 40 % can be more profitable than a 65 EUR SEO lead that signs at 20 %.
With a small budget, what comes first? Under 1,000 EUR/month, start with Ads to validate that demand exists, then shift toward SEO once the market is confirmed, to turn spend into an asset.
