Google Ads and Facebook Ads are the two most widely used digital advertising channels, but they operate on completely different logic: Google captures users who are actively searching for your product or service, while Facebook creates interest among users who might never have searched for what you offer on their own. That difference determines which channel should form the foundation of your marketing budget.
If you run a hotel, a real estate agency, or a rent-a-car company in the region and you're deciding where to put your next €500, this post gives you a direct answer with concrete numbers.
Key Takeaways:
- Google Ads targets active intent: the user searches "apartment Budva summer 2026," you appear
- Facebook Ads targets profiles and interests: the user scrolls their feed, you show them an ad that may spark interest
- Average CPC on Google in the region: €0.30-2.00, depending on industry
- Average CPM on Facebook in the region: €3-8 per 1,000 impressions
- A combined strategy (Google for buyers, Facebook for awareness) reduces cost per conversion by 30-40%
- For tourism and real estate, Google Ads is the primary channel because of high purchase intent
What is the fundamental difference between Google Ads and Facebook Ads?
The key difference lies in user intent at the moment the ad is shown. Google Ads responds to a need that already exists. Facebook Ads tries to create it.
Picture two scenarios. A user types "apartment with pool Kotor August" into Google and your ad appears in the top position. Intent is clear, they're actively looking for what you offer. That's Google Search.
The same user is scrolling Instagram and sees your photos of terraces with sea views. They weren't searching for anything, but the ad catches their interest. That's Facebook/Meta Ads.
Both approaches can lead to a booking, but the path is different and the cost per conversion differs accordingly.
Intent-based vs interest-based targeting
Intent-based targeting (Google Search) means you're bidding on keywords that users actively type in. When someone searches "rent a car Podgorica airport," the probability they're ready to buy is high. Cost per click is higher, but conversion rate is significantly better.
Interest-based targeting (Facebook/Meta) means you're reaching people based on demographics, interests, and behavior. You can target people aged 30-55, with higher incomes, who have shown interest in travel to the Mediterranean. Reach is broader, cost is lower, but intent is weaker.
When is Google Ads the better choice?
Google Ads is better when purchase intent is high and the user is actively looking for a solution. That's the situation where conversion is far stronger because you're responding to an existing need rather than trying to create one.
Use Google Ads when:
- You offer a service or product people actively search for on Google: "accommodation Montenegro," "real estate agency Budva," "rent a car Tivat"
- You need conversions quickly, without waiting to build audience awareness
- You run a B2B business, where purchase decisions are researched and search-driven
- You're targeting local searches ("hair salon Podgorica," "pizza delivery Nikšić")
- You're promoting time-sensitive offers where purchase intent is acute
For tourism, Search campaigns are especially powerful from January through April, when users are planning their summer trips and actively researching accommodation. Every click is more expensive then, but also more valuable.

When is Facebook Ads the better choice?
Facebook Ads is better when you need to build awareness, showcase a visual product, or reach an audience that doesn't yet know it needs your solution. It's the channel for the top and middle of the sales funnel.
Use Facebook/Meta Ads when:
- You're selling a visual product, real estate, luxury accommodation, a car, a fashion brand
- You're targeting a specific demographic that isn't actively searching for your product
- You're building brand awareness in a new market or for a new service
- You're using retargeting to reach people who've already visited your website
- You're promoting content (blog posts, video guides, lead magnets) that attracts potential clients
- You're doing B2C with a mass audience, restaurant, event, retail
Facebook is particularly effective for real estate with high-quality photography, where the visual format of an image or story can create an emotional connection with a potential buyer who hasn't yet started a formal search on Google.

What are realistic budgets in the region?
In Montenegro, Serbia, and Croatia you can run effective campaigns with significantly lower budgets than in Western Europe, because auction competition is also lower.
Google Ads budgets by industry (Montenegro/Serbia/Croatia markets)
- Tourism and accommodation: €300-800/month, CPC €0.25-0.80, goal: bookings
- Real estate: €400-1,200/month, CPC €0.60-2.00, goal: inquiries
- Rent-a-car: €200-600/month, CPC €0.30-0.70, goal: vehicle reservations
- Legal and financial services: €500-2,000/month, CPC €0.80-3.00
- Local business (restaurant, hair salon, clinic): €150-400/month
Facebook Ads budgets by industry
- Tourism and accommodation: €200-500/month, focus on visual content and retargeting
- Real estate: €300-800/month, carousel ads with property photos
- Rent-a-car: €150-350/month, awareness campaigns + retargeting of website visitors
- E-commerce and retail: €200-600/month, catalog ads, Shopping campaigns
- Local business: €100-250/month, local targeting within a radius
One cost many businesses overlook is campaign management. On top of the ad budget, an agency or specialist costs an additional €150-400/month depending on scope. See our detailed breakdown of how much Google Ads costs in Montenegro for the complete picture.
How does a combined strategy work in practice?
The most effective strategy for most businesses isn't "either/or," it's a systematic division of roles between two channels. Google captures those who are ready to buy, Facebook builds a pool of potential customers and handles retargeting.
Here's how it looks as a system:
- Facebook Ads, top of funnel: You show photos and video content to a cold audience that matches your ideal client profile. The goal isn't a direct sale but a website visit and brand awareness.
- Google Remarketing: Users who saw your Facebook ad and visited the website but didn't convert now see your Google ad when they search for something. Retargeting cost is 2-3 times lower than cold campaigns.
- Google Search: Users actively searching for your service hit the Search ad and convert directly.
- Facebook Retargeting: You reach website visitors again with a specific offer or new content.
This circular system reduces cost per conversion by 30-40% compared to a single channel, because each user passes through multiple touchpoints.
Examples by industry: what works where?
Tourism and accommodation
For a hotel or apartments, Google Search Ads is the primary channel during the planning season (January through April). Users are actively searching for accommodation and clicks carry high intent. Facebook Ads plays a role in autumn and winter for brand awareness and early-bird offers.
Concretely: an apartment complex in the Bay of Kotor with a €600/month budget could allocate €400 to Google Search and €200 to Facebook retargeting, and realistically expect 15-25 direct bookings from that. By going direct, they avoid Booking.com's 15-20% commission, meaning the campaign can "pay for itself" from the third booking onward. See how to reduce Booking.com dependence and grow direct bookings.
Real estate
For real estate agencies, Facebook Ads plays a more important role than in most other industries. A property buyer isn't always in active search mode, but they can be stopped in their tracks by a visual presentation of an apartment in the right location. Carousel ads with professional photography and short video walkthroughs are a proven format.
Google Search handles queries like "real estate agency Montenegro" and similar commercial searches, but Facebook builds the list of contacts who've viewed fifteen posts, visited the website twice, and become a warm audience for a direct conversation with an agent.
Rent-a-car
Rent-a-car businesses run almost entirely on intent-based search. The user knows they need a car, types "rent a car Podgorica," and picks from the first few results. Facebook makes sense here only for retargeting and seasonal promotional campaigns.
For rent-a-car websites, Google Ads combined with a strong landing page and an online booking system can be the primary source of reservations during summer.
Local businesses and services
Restaurant, clinic, hair salon, lawyer: Google Local campaigns (Search + Maps) are the priority, because the user searches "dentist Nikšić" and immediately sees a Google Business Profile with an ad. Facebook can support local campaigns for special promotions and events.
Which channel should you choose with a limited budget?
If you have less than €300/month for advertising, the recommendation is clear: start with Google Search Ads on one precisely defined keyword rather than spreading the budget across both channels.
The reason is simple. With €200/month on Google Search you can cover a narrow but highly relevant audience and get conversions. With the same €200 split between two channels, neither has enough data or reach for the campaign to work.
When the budget grows to €500 or more, that's when it makes sense to add Facebook retargeting as a second layer.

Frequently Asked Questions
Can Facebook Ads replace Google Ads?
No, the two channels can't directly substitute for each other because they target different stages of the buying process. Facebook builds awareness and reaches a passive audience, Google captures active intent at the moment of search. Businesses that try to sell directly from Facebook without any Google presence typically have a higher cost per conversion because they have to "warm up" an audience that wasn't searching for anything.
Which channel has better ROI?
Google Search Ads typically delivers higher ROI per conversion because purchase intent is high at the moment of the click. A well-optimized Search campaign in tourism can deliver ROI of 4:1 to 8:1. Facebook Ads has a lower conversion rate but also a lower cost per click, so it can be effective for affordable reach and audience building.
How long does it take for a campaign to start working?
Google Search campaigns start delivering visits within the first few days, but real optimization (enough data for smart bidding) takes 4-6 weeks. Facebook Ads typically needs 2-4 weeks for the algorithm to find the right audience, especially for prospecting campaigns targeting a cold audience.
Can I run campaigns myself or do I need an agency?
You can do it yourself if you're willing to learn and have time for daily monitoring. Both Google Ads and Facebook Ads Manager have solid documentation. That said, a mistake in campaign setup can burn through the entire budget without a single conversion. For budgets above €500/month, an agency or specialist costing €200-350/month is a worthwhile investment because an optimized campaign typically delivers a 30-50% lower cost per click than a poorly configured one.
Is Facebook Ads effective for B2B sales?
Facebook has B2B options (LinkedIn is the better choice for true B2B), but for small and medium businesses in the region, Facebook can work for B2B if you have a clearly defined decision-maker profile and use lead generation formats. For professional services (consulting, legal, IT), Google Search is a reliable channel because buyers actively research providers.
What is retargeting and should I use it?
Retargeting is the practice of showing ads repeatedly to people who've already visited your website or engaged with your content. Both Google and Facebook offer retargeting, and it's one of the most effective options for businesses with a longer buying cycle like real estate or tourism. A user who's looked at your website three times but hasn't booked can be reached with a special offer or a reminder. Retargeting campaigns typically deliver 2-3 times higher conversion rates than cold campaigns.
What is the difference between Google Display Ads and Facebook Ads?
Google Display Network shows banner ads across millions of partner websites, similar to how Facebook shows ads in the feed and Stories. The core difference is in targeting: Display targets by web context and behavior, Facebook by profile and interests within the Meta ecosystem. For brand awareness, both can be useful, but Facebook offers more granular demographic segmentation.
How much does it cost to launch a campaign from scratch?
The technical setup is free on both platforms, there's no setup fee from Google or Facebook. The real costs are: ad budget (minimum €300/month for Google, €150/month for Facebook to be meaningful), creative production for Facebook (photo, video: €100-300 one-time), and possibly setting up conversion tracking on your website if it isn't already in place.
