Ad ranking in Internet marketing is the position of an ad on the page. In paid search marketing, also known as pay-per-click (PPC) marketing, your ad’s ranking is the placement of the ad on the search engine results page, or SERP. An ad rank of 1 puts you in the top position on the search results page.
In Google Ads, ad ranking is determined by your maximum bid for the keyword or ad group multiplied by the matched keyword’s Quality Score.
All other things equal, the more relevant your keywords, ad text and landing pages, the higher your Quality Score, and the higher your ad ranking. That means your ad gets more impressions and more clicks, and ultimately, you get more traffic to your site.
