Part 1: Understanding Google Ads Platform Costs
How Does the Google Ads Auction System Work?
Google Ads is based on a real-time auction system. With every search query, advertisers compete for the coveted ad slots. The final click price results from:
Ad Rank = Quality Score × Bid Price (CPC)
The Quality Score as a Cost Lever
High ad quality means lower costs. Google rewards relevant ads with better positions at more favorable prices. The most important factors:
- Ad relevance: How well does your ad match the search query?
- Expected click-through rate: How likely is a click?
- Landing page experience: Does your landing page offer added value?
Practical tip: Increasing the quality score from 5 to 8 can reduce your click costs by up to 50%!
How much Does a Click Cost on Google Ads?
The click prices vary greatly depending on the industry and competition:
| Industry | Average CPC | Price range |
|---|---|---|
| E-commerce | €0.50 – €2.00 | €0.10 – €5.00 |
| Financial services | €2.00 – €8.00 | €1.00 – €50.00 |

| Local services | €1.00 – €4.00 | €0.50 – €20.00 |
| Legal advice | €5.00 – €20.00 | €3.00 – €150.00 |
Important: These are average values. In exceptional cases, click prices can also reach three-digit euro amounts, especially for highly competitive keywords in the financial or legal sector.
