Ad Rank
Definition
Google's score that determines where your ad appears in search results. Combines your bid, Quality Score, and expected impact of ad extensions.
What is Ad Rank?
Ad Rank is the score Google uses to determine where your ad appears in search results and whether it shows at all. Higher Ad Rank means better positions.
Unlike bidding-only auctions, you can't simply pay your way to the top. Quality matters.
How Ad Rank is Calculated
Ad Rank = Bid x Quality Score x Expected impact of extensions
Your Bid
The maximum you're willing to pay per click. Higher bids increase Ad Rank.
Quality Score
Your ad's relevance and quality (1-10 scale). This multiplies your bid's effectiveness.
Expected Impact of Extensions
Additional information in your ad (phone numbers, links, locations) can boost Ad Rank.
Why Ad Rank Matters
Your Ad Rank determines:
- Position: Higher rank = higher position on the page
- Visibility: Below a certain threshold, your ad won't show
- Actual cost: You only pay enough to beat the next advertiser
Ad Rank in Practice
Example:
- Advertiser A: £3 bid x 8 Quality Score = 24 Ad Rank
- Advertiser B: £5 bid x 4 Quality Score = 20 Ad Rank
Advertiser A wins the top position despite bidding less.

Bid Appropriately
Sometimes you need higher bids, but don't rely on bidding alone.
Ad Rank Thresholds
Google has minimum Ad Rank thresholds. If your Ad Rank is too low:
- Your ad won't show at all
- You won't appear in top positions
- Extensions might not display
This prevents low-quality ads from cluttering search results, regardless of budget.
