Search Engine Marketing (SEM)
"The concept is pretty simple. People search Google for a specific
product or service, they spot your ad and click on it if that’s what they’re looking for. After people click on your ad,
they’ll head over to your website. The only catch is that it’s a paid service known as cost-per-click. The higher the bid,
the higher your ad will appear will in search results. However, you can set a budget."
