- Google Ads brings clients right away, but you pay per click and traffic stops the moment you stop paying. SEO takes months, but the results compound and last.
- ROI: SEO averages 748% vs just 36% for Google Ads (First Page Sage, same dataset) - but ads deliver from day 1, while SEO takes around 9 months to break even.
- Cost: Google Ads runs 0.25 - 2.50 EUR per click (150 - 1,500 EUR/mo ad budget); SEO is 150 - 1,000+ EUR/mo invested in work that stays on your site.
- The smartest move is to combine them: start with ads for quick clients, then shift budget toward SEO over the next 6 - 12 months as organic traffic takes over.
Last month a client asked me: "SEO is great and all, but I need clients NOW." I get it completely. So we suggested running Google Ads for the first 3 months while SEO picks up speed.
And honestly, that's the real answer to "Google Ads or SEO": it depends on your situation. But to make the right decision, you need to understand what you actually get with each option. That's exactly why I wrote this article, with real pricing, concrete data, and no marketing fluff.
SEO ROI: 748% (~7.5:1) vs Google Ads: 36%
But Google Ads delivers from day 1, while SEO takes months. Which matters more for you?
What Google Ads is and what SEO is (explained simply)
Picture Google as a huge marketplace. People walk up and ask "Who builds great websites?" or "Where can I find a plumber near me?" And it's a busy marketplace: Google processes over 5 trillion searches a year (Google, 2025).
Google Ads (paid advertising)
You pay Google to put you right at the top of the results. Next to your result it says a small "Sponsored" label.
Every time someone clicks, you pay. Stop paying and you disappear from the top spots. Instantly. Like a light switch: on or off.
SEO (organic ranking)
You make your site so good and useful that Google places you high in the results on its own. With no "Sponsored" label.
You do not pay per click. But it takes time: months, sometimes a year. The upside is that once you reach the top, you stay there for a long time.
In short: Ads = you pay for quick access. SEO = you invest time for a lasting result. Both lead to the same place, the first page of Google. The path is just different. Either way you need a site that actually converts visitors into customers, otherwise the traffic is pointless.
The real cost of each option
I'm going to be as concrete as possible here, because "it depends" doesn't help you make a decision.
Google Ads: cost per click (CPC) by niche:
| Niche | Cost per click | Monthly budget* |
|---|---|---|
| Services (plumbing, locksmith, cleaning) | 0.25 - 0.75 EUR | 150 - 300 EUR |
| Restaurants, salons, fitness | 0.40 - 1.00 EUR | 200 - 400 EUR |
| Web design, marketing | 0.50 - 1.50 EUR | 250 - 600 EUR |
| Real estate, loans | 1.00 - 2.50 EUR | 400 - 1,000 EUR |
| Insurance, lawyers | 1.50 - 2.50+ EUR | 500 - 1,500 EUR |
* CPC ranges are based on our own Google Ads campaigns and Bulgarian-market benchmarks. Monthly budget assumes 20-30 clicks per day; actual values depend on competition and campaign settings.
SEO: monthly investment:
- 150 - 300 EUR/mo:Basic SEO for a local business with low competition
- 300 - 600 EUR/mo:Mid-range SEO for a national business or more competitive niche
- 600 - 1,000+ EUR/mo:Aggressive SEO for e-commerce or high-competition niches
The big difference: with Google Ads, the ad-budget money goes to Google. With SEO, the money goes into actual work on your site: content, optimization, technical maintenance. That work stays, even if you stop paying tomorrow.
Time to the first clients
Ads wins this one hands down. If you need clients this week, SEO simply cannot help you. Period.
To put a number on it: First Page Sage found that the average SEO campaign takes about 9 months to break even (data from Q1 2021 - Q3 2025). Google Ads, by contrast, can generate its first leads on day one.
Google Ads
Right away
Launch the campaign in the morning and you can have the first calls coming in by the afternoon. Literally. Setup takes 1 to 3 days, and Google approval takes hours.
SEO
3-12 months
Google has to crawl your site, index the pages, and evaluate quality against the competition. That's a process. For a detailed timeline, see here.
That's why I told my client honestly: if he needs clients by the end of the month, we start with ads. SEO is an investment for the next 2-3 years, not next week.
What happens when you stop paying?
And here is the other side of the coin. Everyone loves the quick wins of paid ads, until the moment comes to cut the budget.
This is exactly why SEO compounds: First Page Sage measures SEO ROI averaged over a 3-year period, because rankings you earn today keep returning traffic long after the work is done. Ad traffic, on the other hand, lasts exactly as long as the budget does.
You stop Google Ads:
- Traffic stops instantly, same day
- The phone stops ringing
- It's as if you were never in Google
- Everything you paid is in the past
You stop SEO:
- Rankings stay for months, even years
- Organic traffic keeps coming in
- The content you created works even while you sleep
- Competitors will gradually push you down (but slowly)
I know a Bulgarian HVAC business whose site we built - the owner has not touched it in 2 years, yet it still ranks on the first page for its main keywords. Try stopping Google Ads for 2 days and see what happens.
Which one has the better ROI?
Ok, let's talk money. Because at the end of the day, that's what matters: how much you put in and how much you get back.
SEO ROI (First Page Sage, 2026)
748%
For every 1 EUR invested in SEO, you get about 7.50 EUR back. But that's the average over a 3+ year horizon. The first year may even be in the red.
Google Ads ROI (First Page Sage, 2026)
36%
For every 1 EUR spent on ads, you get about 1.36 EUR back. Far lower ROI than SEO, but it comes immediately and predictably.
A few more numbers worth knowing:
- The average Google Ads search CTR is 6.66% - most clicks still go to organic results (WordStream, 16,000+ campaigns, 2025)
- 70% of marketers confirm that SEO generates more sales than PPC (Databox survey)
- The #1 organic result earns a 27.6% click-through rate (Backlinko, analysis of 4M results)
Example with numbers: if you invest 500 EUR/month in Google Ads for 1 year = 6,000 EUR. Stop paying and the revenue stops. If you invest 500 EUR/month in SEO for 1 year = 6,000 EUR. But once you stop, the site keeps generating traffic and clients. The effect compounds.
Why do people skip the ads?
Here's something ad agencies don't love talking about: most people do not click on the ads.
27.6% of clicks
go to the #1 organic result alone, far more than a typical paid ad attracts. People recognize the ads and gravitate toward the organic listings.
Source: Backlinko, analysis of 4M search results
Why? Because people know what an ad looks like. They see "Sponsored" and instinctively scroll past. An organic result reads like "Google is telling me this site is good." An ad reads like "this site paid to be here."
Of course, a share of users still click on ads, and for certain searches that is plenty. If you sell something with a high customer value (custom kitchens, legal services), even a modest conversion rate from ads can pay off.
But if you want maximum reach and trust from potential customers, SEO is the way. Especially for Google Business Profile: according to Google, 76% of people who search for something nearby visit a business within a day.
When is Google Ads the right choice?
Paid advertising isn't "bad." You just need to know when and why to use it. And when it's done well it converts: the average Google Ads search click-through rate is 6.66% (WordStream, 16,000+ campaigns, 2025). Here are the situations where Google Ads is the right call:
A new business just starting out
You have no online presence, no organic traffic, no reviews. Ads give you visibility from day 1 while everything else is being built.
Seasonal promotion or event
Black Friday, Christmas, holiday season: if you have a specific offer for a short window, SEO simply cannot move fast enough. Ads are the only option.
Testing a new market or product
Not sure if people will buy? Run ads for 2 weeks and see. It's cheaper than 6 months of SEO for something that may not pan out.
You have a high customer value
If a single client is worth 2,500+ EUR to you (renovations, legal services, B2B), even expensive clicks pay off. One client can cover the whole monthly budget.
When is SEO the right choice?
SEO is for people who think long term. If you know your business will still be here 3-5 years from now, SEO is probably the smartest investment you can make. The math backs it up: First Page Sage puts the median SEO ROI at 748% over a three-year horizon (data through Q3 2025).
A long-term business that will still be around in 5 years
If you plan to stay in the market for the long haul, SEO is the most profitable investment. The effect compounds: every article, every optimization keeps working for you for years.
Limited monthly budget
With Ads you pay constantly. With SEO, you invest once and the results stick around. For a business with a 250 EUR/month budget, SEO delivers much better long-term value.
Local business
Hair salon, auto repair shop, dentist: local SEO with Google Business Profile optimization can get you into the Google Maps top 3 within 3-4 months. And you don't pay per click.
You want to build authority in your niche
Quality content and strong Google rankings build trust. Clients who find you organically already have a higher opinion of you than those who arrive through ads.
Our recommendation: combine the two
The truth is that the question is not "one or the other." The smartest strategy is to use both, but in different ways at different stages.
Here's what we recommend to most of our clients:
Phase 1: Months 1-3 (Ads leading, SEO preparing)
You launch a Google Ads campaign for your core services. In parallel, we run a technical SEO audit and optimization, create content, and set up Google Business Profile.
Sample budget split: 60% Ads / 40% SEO
Phase 2: Months 4-6 (Balanced)
SEO starts producing first results. Organic traffic grows. You trim the ad budget slightly and increase the SEO investment.
Sample budget split: 40% Ads / 60% SEO
Phase 3: Months 7-12 (SEO leading)
Organic traffic now drives a steady flow of clients. Google Ads stays on only for specific campaigns and remarketing. Most of the budget goes to SEO maintenance and new content.
Sample budget split: 20% Ads / 80% SEO
Phase 4: Month 12+ (Autopilot)
SEO carries the bulk of the traffic. Ads are only used for new products, seasonal promos, or whenever you want an extra boost. The cost to acquire a customer has dropped dramatically.
Sample budget split: 10% Ads / 90% SEO maintenance
This strategy isn't something we made up. Most successful online businesses follow a similar model: they start with ads and gradually shift toward organic traffic. There are technical pieces that help too: a fast site with healthy Core Web Vitals improves both ads and SEO at the same time.
Comparison table: Google Ads vs SEO
For those who like to see it all at a glance:
| Criterion | Google Ads | SEO |
|---|---|---|
| Speed of results | Immediate (hours) | 3-12 months |
| ROI | 36% average | 748% average |
| Cost per click | 0.25 - 2.50+ EUR | Free* |
| Monthly cost | 150 - 1,500+ EUR ad budget | 150 - 1,000+ EUR |
| When you stop paying | Traffic stops instantly | Traffic lingers for months/years |
| User trust | Most clicks go to organic | Perceived as "Google-approved" |
| CTR (top result) | ~6.66% avg (ads) | 27.6% (#1 organic) |
| Predictability | High: you control the budget | Medium: depends on the algorithm |
| Scalability | More money = more traffic | Compounding effect over time |
| Ideal for | Quick results, tests, promos | Long-term growth, authority |
* SEO clicks are free, but SEO itself requires investment in specialists and content.
So which is better?
It depends on you. If you need clients tomorrow, Google Ads. If you are thinking about the next 3-5 years, SEO. If you want the best of both worlds, combine them.
Most of our clients start with Ads while we work on SEO in parallel. After 6 months, organic traffic takes over a large share of the load and the ad budget can be reduced. You win short term and long term.
