There are two types of SEM: paid search advertising and organic search marketing.
Paid search advertising is a type of SEM that allows you to place ads on search engines. These ads are typically displayed at the top or bottom of the search results page, and they can be targeted to specific keywords or phrases.
Organic search marketing is a type of SEM that helps you improve your website’s ranking in the search results pages. This can be done through optimizing your website content, building backlinks to your website, and other methods.
