How Google Ads Works: The Auction System
Every time someone performs a search, Google runs an auction to determine which ads to show. Three main factors determine ad placement:
- Bid Amount – How much you’re willing to pay per click (CPC).
- Quality Score – Based on ad relevance, expected CTR, and landing page experience.
- Ad Extensions and Format – Google prefers ads with more useful information like phone numbers, location, sitelinks, etc.
Even if you bid below a competitor, your ad may rank higher if it’s of higher Quality Score. That is why ad quality is equally critical as your budget.
