Google Ads operates on an auction model. Every time a user enters a query, the algorithm determines in milliseconds which ads to show and how much to charge the advertiser. The final price depends on four factors.
The more advertisers compete for the same queries, the more expensive the click becomes. In medicine and law, auctions are overheated: 5-10 advertisers for a single query like “dentist Kyiv”. In niche e-commerce, competition is lower, and CPC can be under one hryvnia.
Quality Score is Google’s internal rating from 1 to 10. It considers ad relevance to the query, landing page quality, and expected CTR (click-through rate). With a Quality Score of 8-10, you pay less than a competitor with a QS of 4-5, even if their bid is higher. Google prefers showing relevant ads.
In practice, the difference is significant. We have seen accounts where, after optimizing landing pages and ad copy, CPC dropped by 30-40% while maintaining the same positions. No budget change required.
Tires in autumn and spring see CPC rise 40-60% compared to summer months. Air conditioners in summer, heating in winter, flowers before March 8th. Planning a budget without considering seasonality means either overpaying during peaks or missing traffic during sales seasons.
One of our clients in the auto niche increases their budget by 50% annually during the “tire change” period and achieves a 21% conversion rate on seasonal campaigns. Outside the season, the same campaign yields only 8-10%.
Different Google Ads campaign types have fundamentally different CPCs. Based on one of our clients, a tire shop chain:
The algorithm finds the cheapest traffic across all Google platforms.
Product listings with photos and prices, high purchase intent.
Maximum control, but also maximum competition. More details on setting up search campaigns are in our guide on Google Ads setup ().
The figures below are benchmarks for 2026 for the Ukrainian market. The range is wide because CPC depends not only on the niche but also on the region, specific queries, and account quality.
The most expensive niche in Ukraine. Queries like “dental implants Kyiv” or “laser vision correction” have a heated auction. This is compensated by high average order value: one conversion can generate $500-$2,400 in revenue.
A wide range. Niche products with low competition are closer to $0.07. Electronics and appliances are closer to $0.37. On Performance Max for online stores, CPC is often under $0.02-$0.05, as in the case of our auto parts client.
Depends on the sub-niche. Import car sales are expensive, but with a 2500% ROAS, it pays off handsomely. Auto parts on PMax are cheap (under $0.02). Service services are in the mid-range but with a higher check.
Low traffic volume, high cost per click, long sales cycle. However, the average check is correspondingly high. One closed deal can cover the ad budget over several months.
Query “apartment repair Lviv” is $0.73-$1. “Online English courses” is $0.37-$0.61. Local services are cheaper than nationwide ones.
“Cost per click is not the metric to look at first. A CPC of $1 with a 15% conversion rate and an average check of $750 is cheap advertising. A CPC of $0.05 with a 0.3% conversion rate and a check of $10 is burning the budget. Calculate unit economics, not clicks”

The formula is simple. Multiply the expected CPC by the number of clicks needed for one conversion. This gives you the cost of one lead or sale. Then, multiply by the desired number of conversions per month.
CPC is $1. Average site conversion rate for dentistry is 3-5%. To get one lead, you need 20-33 clicks. Cost per lead: $25-$40. Need 30 new patients per month? Ad budget: $750-$1,200. Plus agency management from $500/month. Total: from $1,200-$1,700/month.
CPC is $0.12. Site conversion rate is 2%. Cost per order from ads is $6. With a 30% margin and an average check of $50, profit per order is $15. ROAS: 800%. The budget scales as much as the business can handle.
Minimum threshold for algorithm learning: Google recommends 10-15 conversions per week for stable optimization. Less means the algorithm doesn’t get enough data and works unstably.
Converted to ad budget (excluding agency service fees), this means:
It is crucial to distinguish between two cost components: the ad budget (money going directly to Google) and the agency service fees (setup, management, optimization).
Includes niche analysis, keyword collection, campaign structure, ad creation, and conversion setup.
Monitoring, bid optimization, A/B testing, reporting, negative keyword work, scaling.
Technical audit, content strategy, page optimization, link building.
Multiple channels, unified strategy, cross-channel analytics.
Therefore, the real total investment for a small business with one channel is from $1,100-$1,350/month (agency services + ad budget
For a medium business with 2-3 channels, it is from $2,700-$3,700/month.
ROAS (Return on Ad Spend) is the ratio of revenue to ad spend. A ROAS of 400% means: for every hryvnia invested, four returned.
Benchmarks by niche for the Ukrainian market:
With a well-optimized feed and PMax campaigns, 600-800% is achievable. Below 300% indicates problems with the feed, pricing, or site conversion.
A wide range due to margin differences. Auto parts are closer to 500%. Car sales and high-value services can exceed 2000%, as with our client in the import car niche.
Dentistry, repair, education. High checks compensate for expensive clicks. Below 300% means it’s time to review the funnel from click to payment.
However, considering LTV (lifetime value), the real payback is significantly higher. One closed contract can pay off a year of ad spend.
A consolidated table for planning. The “Recommended Budget/Month” column represents the total investment (agency services + Google ad budget). Figures are benchmarks for the Ukrainian market as of 2026. Actual values depend on account quality, region, and specific queries.
Over years of practice, we have seen both scenarios often enough to describe them clearly.
The client is searching for it in Google. The site is ready to convert traffic: fast, with prices, and a simple contact form or cart.
A $10 service with a CPL of $10 won’t work mathematically. A $375 service with a CPL of $10 has sufficient margin.
At least 2-3 months with a sufficient budget (from $1,100/month for one channel). First month: algorithm learning. Second: optimization. Third: scaling.
An innovative product that no one searches for cannot be reached with contextual ads. Meta Ads or YouTube are needed to create demand.
Slow, no prices, no mobile version, with a 15-field form. Traffic will come and leave. The ad budget will burn, and the advertiser will say “Google Ads doesn’t work.” It works. The site doesn’t.
At $5-$7/day in a competitive niche, the campaign won’t gather enough data for optimization. For e-commerce, the minimum is $30/day; for services, from $15/day. Results are unpredictable. It is better to save for a full test or start with SEO, which takes time but doesn’t require daily click costs
“I often hear ‘Google Ads is expensive.’ No. Expensive is launching ads without preparation and burning the budget in a month. With the right approach, even a niche with a $1 CPC can yield a 400-600% ROAS. The difference is not in the budget but in the methodology.”
