What Is Ad Strength?
Ad Strength is a score in Google Ads that tells you how effective and high-quality your ad is. It helps you understand whether your ad has the right combination of headlines, descriptions, keywords, and relevance to attract users and perform well in auctions.
In simple words: Ad Strength shows how strong or weak your ad is — and how likely it is to perform well.
Why Ad Strength Matters
A good Ad Strength score means:
- Higher ad visibility
- Better click-through rates
- Better Quality Score
- Lower cost per click
- Improved ad performance
Google wants ads that are useful and relevant, so better ad strength = better results.
Ad Strength Levels
Google shows Ad Strength in four levels:
- Poor
- Average
- Good
- Excellent
Each level tells you how much improvement is needed.
How Google Measures Ad Strength
Google checks:
- Variety in headlines
- Variety in descriptions
- Keyword relevance
- Use of unique phrases
- Clarity of message
- Ad creativity
- Final URL matching
- Use of responsive assets
The more diverse and relevant your ad content is, the higher your score.
Simple Example
Let’s say your keyword is “digital marketing course”.
Poor Ad Strength:
1–2 repeated headlines
Descriptions missing keywords
Weak messaging
Excellent Ad Strength:
10–15 different headlines like:
- Learn Digital Marketing Course Online
- Become a Certified Digital Marketer
- Join Classes with Live Projects
AND
Multiple unique descriptions covering features, fees, duration, and benefits.
This gives Google more combinations to test → better performance.
