With all of the recent changes in Quality Score (QS), including the new landing page load time piece, I thought it would be a good time to review all the pieces of how Google AdWords Quality Score is perceived to work.

What is my Google AdWords ‘Quality Score’ and how is it calculated?

According to Google, Quality Score is a dynamic variable assigned to each of your keywords. It’s calculated using a variety of factors and measures how relevant your keyword is to your ad text and to a user’s search query.

Two kinds of Quality Score

  1. Quality Score for Minimum Bid: Quality Score also partly determines your keywords’ minimum bids.
  2. Quality Score for Ad Rank: Quality Score influences your ads’ position on Google and the Google Network.
    In general, the higher your Quality Score, the better your ad position and the lower your minimum bids.

In-depth look at Quality Score Formulas
The QS formula used varies depending on whether it’s calculating for minimum bids or for assigning ad rank. In addition, it varies depending on whether it’s affecting

  • a keyword-targeted ad on the search network
  • a keyword-targeted ad on the content network
  • or a placement-targeted ad
    Google will continue to improve these formulas, but the core components will remain more or less the same.
