Conversion tracking measures actions users take after clicking an ad.

An impression is counted every time an ad is displayed.

CTR is calculated by dividing clicks by impressions and multiplying by 100.

CTR stands for Click-Through Rate and measures the percentage of users who clicked an ad.

Ad relevance measures how closely an ad matches user intent and keywords.

A higher Quality Score can reduce CPC and improve ad rankings.

Quality Score is Google’s rating of ad relevance, landing page experience, and expected click-through rate.
