Quality Score is a grade that Google gives your keywords.
10/10: Perfect. Your ad is helpful and relevant.
1/10: Terrible. Your ad is not relevant to what people are searching for.
Why does it matter? Google rewards high-quality ads with lower prices.
Your score comes from three specific data points:
| Expected Click-Through Rate (CTR) | Does Google think people will click your ad? If your past performance is good, this score goes up. |
| Landing Page Experience | Does your website load fast? Is it easy to read? Do people stay on the page or leave immediately? |
| Ad Relevance | Does the text in your ad match the keyword the user searched for? |
Deep Dive on Ad Relevance: If a user searches for "Red Tennis Shoes":
| Ad A says | "Buy Red Tennis Shoes." | (High Relevance). |
| Ad B says | "We Sell Sports Equipment." | (Low Relevance). |
| Ad C says | "Blue Trucks for Sale." | (Zero Relevance). |
To fix low Ad Relevance, make sure your keywords are actually written inside your Ad Headlines.
Think of Quality Score like a multiplier for your money.
| The Discount | (Score 7-10) | Google wants to show your ad because users like it. They might charge you 30-50% less per click. |
| The Neutral Zone | Score 4-6 | You pay the market average. |
| The Penalty Tax | Score 1-3) | Google thinks your ad is annoying or irrelevant. They will charge you up to 400% more just to show your ad. |
Simple Rule: If your CPC is very high, check your Quality Score first. You might be paying the "Penalty Tax."
Your Quality Score relies heavily on Click-Through Rate (CTR) and User Behavior. Click fraud attacks can destroy both of these:
Competitor Sabotage: A competitor's bot searches for your keyword 1,000 times but never clicks your ad. This makes your CTR look terrible (0%), which drops your Quality Score.
Bounce Rates: A bot clicks your ad but leaves the website in 0.1 seconds. Google sees this and thinks, "This landing page must be bad," and lowers your score.
The Fix: Using ClickSambo prevents these bad interactions.
