Google Ads vs Sklik: Where to Advertise in the Czech Republic

PPC advertising is the fastest path to new customers online. In the Czech Republic, you have two main platforms to choose from -- Google Ads and Sklik (Seznam). Each has its strengths, and the right choice (or combination) can dramatically affect your return on investment.

Market Share: Google vs. Seznam

Before we dive into the comparison, let's look at the current numbers. Google holds roughly 80% market share in Czech search. Seznam maintains about 15--18%, with the rest going to other search engines.

Does that mean Sklik isn't worth it? Absolutely not. That 15--18% represents millions of searches daily and a specific demographic that could be exactly your target audience.

Google Ads: The Global Giant

Google Ads Advantages

• Largest reach -- 80% of Czech searches
• Advanced targeting -- remarketing, in-market audiences, custom segments
• Diverse formats -- Search, Display, YouTube, Shopping, Performance Max
• Artificial intelligence -- Smart Bidding, automated targeting, Broad Match with AI
• Google Shopping -- visual product ads right in search results
• YouTube Ads -- video formats with massive reach
• International reach -- one campaign setup for multiple countries

Google Ads Disadvantages

• Higher cost per click -- competition drives prices up
• Complexity -- dozens of campaign types and settings
• Click fraud -- higher risk with display campaigns
• Steep learning curve -- easy to lose money without experience

Sklik: The Czech Specialist

Sklik Advantages

• Lower cost per click -- 20--40% cheaper than Google Ads
• Czech support -- phone and email in Czech
• Specific demographics -- older population, less tech-savvy users
• Product search -- integration with Zbozi.cz
• Lower competition -- fewer advertisers = lower prices
• Business clients -- many B2B customers still use Seznam
• Simplicity -- a cleaner interface than Google Ads

Sklik Disadvantages

• Smaller reach -- 15--18% of the market
• Limited targeting -- fewer advanced audience segments
• Fewer formats -- no YouTube Ads or Performance Max equivalent
• Slower innovation -- new features lag behind Google
• Limited automation -- fewer AI features for optimization

Detailed Comparison

When to Choose Google Ads

Google Ads is the right choice if:

• You're targeting a younger demographic (18--45) -- this group uses Google almost exclusively
• You sell online -- Google Shopping is the most effective channel for e-commerce
• You want video ads -- YouTube is the second largest search engine in the world
• You need remarketing -- Google has the most sophisticated remarketing tools
• You're expanding internationally -- one platform for all markets
• You have a larger budget -- higher budgets let you better leverage AI optimization

When to Choose Sklik

Sklik is ideal if:

• You have a limited budget -- lower CPC means more clicks for the same money
• You're targeting an older demographic -- 45+ still heavily uses Seznam
• You're a local business -- smaller companies often see higher conversions on Seznam
• You sell on Zbozi.cz -- integration is straightforward and effective
• You're new to PPC -- a simpler interface and Czech support make getting started easier
• You want to complement Google -- Sklik excels as a secondary channel

The Optimal Strategy: Combining Both Platforms

Most successful advertisers in the Czech Republic use both platforms simultaneously. The key is proper budget allocation.

Recommended Budget Split

Small budget (up to 10,000 CZK/month):

• Google Ads: 70%
• Sklik: 30%

Medium budget (10,000--50,000 CZK/month):

• Google Ads: 65%
• Sklik: 25%
• Zbozi.cz: 10%

Large budget (50,000+ CZK/month):

• Google Ads (Search): 40%
• Google Ads (Shopping/PMax): 20%
• Sklik: 15%
• Zbozi.cz: 10%
• YouTube/Display: 15%

These are ballpark figures. The actual split depends on results and conversions -- always shift budget toward whichever channel delivers the best ROI.

How to Measure Performance Properly

Without proper measurement, you'll get lost in PPC. For a complete overview of metrics and attribution models, read my article on how to measure online marketing ROI. Set up the following:

Google Analytics 4

• Connect with both Google Ads and Sklik
• Track conversions (purchases, forms, calls)
• Use attribution models to understand the customer journey

Conversion Tracking

• Google Ads conversions -- native tracking in Google
• Sklik conversions -- Seznam's retargeting code
• UTM parameters -- for precise attribution in GA4

Key Metrics

• CPA (cost per acquisition) -- how much one customer costs
• ROAS (return on ad spend) -- how much you earn for every 1 CZK invested
• Conversion rate -- percentage of visitors who buy
• Quality Score -- affects cost per click

Most Common PPC Mistakes

1. No conversion tracking -- without data, you can't optimize
2. Keywords too broad -- you're paying for irrelevant clicks
3. Ignoring negative keywords -- filter out irrelevant queries
4. Same ads for everyone -- personalize by audience
5. Sending traffic to the homepage -- always use a relevant landing page
6. Set and forget -- PPC requires regular optimization
7. Last-click attribution only -- customers go through multiple touchpoints

PPC Trends for 2026

• AI optimization -- machine learning is replacing manual bidding
• Privacy-first -- the end of third-party cookies is changing remarketing
• Automation -- Performance Max and similar formats are growing
• Conversational ads -- AI chatbots in ad formats
• Video-first -- short videos are dominating even in search

Conclusion

Google Ads and Sklik aren't competitors -- they're complementary channels. Google offers greater reach and more advanced tools, while Sklik brings lower prices and access to a specific Czech demographic. The best results come from combining both platforms with ongoing optimization based on real data. Keep in mind that even the best campaign fails if visitors don't buy once they land — so it pays to tackle e-shop conversion optimization in parallel.
