Rate your three Quality Score components the way Google grades them and get an estimated 1–10 score — plus what a low score is quietly costing you in CPC. Higher QS = lower cost per click for the same ad rank.
Expected CTR
How likely your ad is to be clicked vs competitors for this keyword.
Ad relevance
How closely your ad copy matches the keyword's intent.
Landing page experience
Relevance, transparency and speed of the page after the click.
Estimated Quality Score
6/10
Average
~67% higher CPC than a QS 10 ad
Ad rank = bid × Quality Score, so a low QS means you pay more (or lose position). The cheapest win is usually the weakest component below.
An estimate — Google's exact QS formula and CPC discount aren't published. Use the three component ratings from your Keywords column, and fix the lowest one first (usually expected CTR or landing-page experience).
