Search Engine Marketing (SEM) is a digital marketing strategy that focuses on promoting websites and increasing their visibility in search engine results pages (SERPs) through paid advertising. Here’s a summary of Search Engine Marketing:

1. Paid Search Advertising: SEM primarily involves pay-per-click (PPC) advertising, where advertisers bid on keywords relevant to their business. Ads are displayed on search engine results when users search for those keywords. Advertisers pay only when their ads are clicked.
2. Ad Campaign Setup: SEM campaigns require creating targeted ad groups, selecting keywords, and writing compelling ad copy. Advertisers can set specific parameters such as budget, ad schedule, and geographic targeting to reach their desired audience.
