It basically shows how good your advertising campaign is targeting your audience.
A high Quality Score of 10/10 means your ads are offering best customer experience in Google eyes.
For that, the Search Engine will reward you with up to 50% lower Cost-Per-Click and higher ad position.
In return, this leads to more visitors to your page.
