The goal is to increase the website’s rankings for specific keywords.SEM (Search Engine Marketing): It is a broader term that encompasses all activities involved in promoting a website on search engines. While it includes SEO, SEM also involves paid advertising on search engines, such as pay-per-click (PPC) campaigns.

Cost:

Long-Term vs. Short-Term:
