A. when your ad appears within the search results
B. when a conversion happens on your website
C. when your ad is clicked by someone
D. when someone stays on your website for more than 2 minutes
Answer:-
When advertising using search engine marketing (SEM), you only pay when your ad is clicked by someone.
Explanation:-
SEM operates on a pay-per-click (PPC) model, which means that advertisers only pay when a user clicks on their ad. This is also known as cost-per-click (CPC) advertising. Advertisers bid on keywords related to their business, and when a user searches for those keywords, an auction takes place to determine which ads will appear and in which order.
When a user clicks on an advertiser’s ad, they are directed to the advertiser’s website, and the advertiser is charged for that click. The cost of the click varies depending on the bid amount, the competition for the keyword, and the quality of the ad and landing page.
The other options are not accurate for SEM advertising. You do not pay when your ad appears within the search results (option A). You also do not pay when a conversion happens on your website (option B) or when someone stays on your website for more than 2 minutes (option D). While conversions and engagement metrics are essential for measuring the success of an SEM campaign, they are not directly tied to the cost of advertising on search engines.
