Google Ads buys time: you appear tomorrow, you pay per click, and you disappear the day you stop paying. SEO builds an asset: it takes four to eight months, but then it brings visitors with no cost per click.
The right question is not “which of the two”. It is “what do I need first, with the money I have today”.

The core difference
| Google Ads | SEO | |
|---|---|---|
| When you appear | Immediately, day one | In 3–8 months |
| How you pay | Per click | Per month of work |
| If you stop | You vanish at once | You stay for months |
| Control | Full: who, where, when | Indirect |
| Cost over time | Flat or rising | Falls per visit |
| User trust | Lower (marked as an ad) | Higher |
| Suits | Immediate demand, seasonality, testing | Recurring demand, long-term presence |
The fifth row is the one people ignore. In Ads, the hundredth click costs what the first did. In SEO, the hundredth visitor costs almost nothing.
What each costs
Google Ads. Cost per click in the Greek market varies by sector — from around €0.20 in low-competition local services to over €2 in legal, insurance and medical.
| Item | Indicative range |
|---|---|
| Cost per click (local services) | €0.20 – €1.50 |
| Realistic minimum monthly budget | €300 – €600 |
| Campaign management | €150 – €500 a month, or 10%–20% of spend |
| Campaign setup | €200 – €800 one-off |
SEO.
| Item | Indicative range |
|---|---|
| Initial audit and fixes | €300 – €900 one-off |
| Monthly support | €200 – €500 |
| Content (per article or page) | €80 – €250 |
| Local SEO (profile, listings) | €300 – €700 one-off |
Note that the two are not comparable in absolute spend, but in cost per customer. That is where the real comparison happens.
How fast each pays off
| Time | Google Ads | SEO |
|---|---|---|
| Week 1 | First clicks and calls | Nothing visible |
| Month 1 | You know which terms bring customers | Technical fixes |
| Month 3 | An optimised campaign | First long-tail movement |
| Month 6 | Steady flow, steady cost | Rankings on core terms |
| Month 12 | Same cost per customer | Cost per customer falling |
Month twelve is where the whole difference sits. Ads cost the same; SEO starts delivering “free” visits on work you already paid for.
When to start with Google Ads
- You just opened and need customers now, not in six months.
- You have seasonality and must be present in specific weeks.
- You are launching a new service and want to test whether demand exists.
- Organic competition is very strong and would take years.
- You want data. In three months you learn which terms bring customers — information that costs far more to guess at.
When to start with SEO
- Demand is steady year-round and recurring.
- Your margin is thin and cost per click eats it.
- The sales cycle is long and customers read before they buy.
- You are a local business — local SEO and a Google Business Profile are among the best returns in marketing, at almost no cost per contact.
- You are thinking long term and can wait two quarters.
For local businesses, our local SEO guide is almost always the first step, before a single euro on advertising.
The combination that works
The smartest approach is not to choose. It is to sequence them correctly.
- Months 1–3: Ads to learn. Small budget, tight targeting, the goal being to discover which terms produce calls.
- In parallel: local SEO. Profile, reviews, listings. Costs little and pays off quickly.
- Months 3–6: SEO built on Ads data. Write pages for the terms you already know convert.
- Months 6–12: shift the budget. As organic climbs, reduce Ads on the terms you now win organically.
- After that: Ads only where they earn it. Seasonal campaigns, new products, fiercely competitive terms.
This sequence exploits the biggest advantage of Ads that nobody mentions: it is the cheapest keyword research tool in existence.
Want an allocation plan for your case?
Tell us your monthly budget and we will propose how to split it across the first six months.
How to split your budget
| Situation | Ads | SEO |
|---|---|---|
| New business, need customers now | 70% | 30% |
| Established business, seeking growth | 40% | 60% |
| Local business with a physical shop | 30% | 70% |
| E-shop in a competitive sector | 50% | 50% |
| Very small budget (under €300) | 0% | 100% |
That last row matters. Below €300 a month, Ads cannot gather enough data to optimise. The same money in local SEO and content returns more.
How to measure both fairly
One metric compares them honestly: cost per customer.
Cost per customer = total channel spend ÷ customers it produced
To measure it you need two things:
- Conversion tracking on your site: calls, forms, orders.
- Separate source tags (utm) on each channel, so they do not blend together in Analytics.
And a reminder: if your site does not convert, neither channel will save you. The ten most common problems are here.
The five mistakes
- Ads with no conversion tracking. You pay for clicks and never learn what they produced.
- Ads pointing at the homepage. Every ad needs a page matching its promise.
- SEO with no content. Technical fixes alone do not produce rankings.
- Stopping SEO in month three. Right before it starts working.
- Comparing on the wrong metric. Clicks are not customers.
Frequently asked questions
Can I do SEO only?
Yes, if you can absorb the wait. It is the usual choice for local businesses with small budgets.
Do Ads help organic rankings?
Not directly. They help indirectly, by showing you which terms are worth pursuing organically.
What budget do I need to test Ads?
Typically €300–€600 a month for two or three months. Less does not produce reliable conclusions.
Do I need a website for Ads?
Yes, and a good one. See why your business needs a website.
Which works better for an e-shop?
Both, with SEO winning over time and Ads covering seasonal peaks.
The decision in three questions
How urgent is it? How large is your margin per customer? And how steady is demand in your sector?
Urgent plus healthy margin means Ads. Steady demand plus thin margin means SEO. Most situations want both, in the sequence described above.
