What are the 3 principles of Google Ads?

The three main principles of Google Ads are:

Relevance: Google Ads uses relevance to match ads to the users that are most likely to be interested in them. Ads are matched to the keywords that users type into the search bar, as well as to the content of the websites that users visit.

Quality Score: Google Ads uses a quality score to determine the relevance of an ad. Quality score is a metric that measures the relevance and expected performance of an ad, taking into account factors such as the relevance of the keywords, the relevance of the ad copy, and the relevance of the landing page.

Bid: Google Ads uses a bidding system to determine which ads are shown to users. Advertisers bid on keywords, and the highest bidder’s ad is shown to users when they search for that keyword. However, the bid is just one of the factors that determine the ad ranking, Quality score and relevance are also considered.

All these principles are used together to ensure that users see the most relevant and high-quality ads possible.
