Hi Friends,
A less known fact about Ad Rank is that it plays a huge role in determining the actual cost-per-click that your competitors pay when someone clicks on their ads: Google charges Cost-per-click or CPC whenever someone clicks on your ad.

Ad ranking in Internet marketing is the position of a pay-per-click (PPC) ad on a search engine results page (SERP). The position of this ad depends on the position of each keyword included in the ad, which is determined by your bid for that keyword or ad group multiplied by the matched keyword's Quality Score.
