Search Engine Marketing (also known as Search Marketing) is the process of acquiring traffic from search engine marketing tools, either organically or through paid advertisements
SEO (Search Engine Optimization) and PPC (Pay Per Click) are the two main types of search engine marketing (Paid Search Advertising).
SEO is the process of obtaining free traffic from search engines by achieving high rankings in the SERPs, whereas PPC is the process of paying for your ads to appear on search engine results pages.
Businesses use search engine marketing to pay for their advertisements to appear alongside search queries in search engines. Search engine marketing examples include Google, Yahoo, Safari, and Bing, among others.
