The correct formula for determining an actual CPC as when an advertisement is clicked can be mathematically derived as __________.
The correct formula for determining an actual CPC when an advertisement is clicked can be mathematically derived as QS * Max CPC (bid).
Google uses a formula that combines Quality Score (QS) and maximum cost-per-click (CPC) bid to determine the actual CPC when an advertisement gets clicked.
This formula is used to calculate the Ad rank, which is used to determine the position of the ad on the search engine results page (SERP). Ad rank is calculated using the following formula:
Ad Rank = Quality Score * Max CPC (bid)
The Quality Score is a metric that evaluates the relevance and usefulness of your ad and takes into account factors such as the relevance of the ad, the relevance of the landing page, and the expected click-through rate (CTR).
The maximum CPC bid is the highest amount that an advertiser is willing to pay for a click on their ad.
By using this formula, Google can ensure that the ads that are shown to users are both relevant and useful, while also taking into account the advertiser's budget.
