SEO and SEM are two different strategies in digital marketing.

SEO, or Search Engine Optimization, is the process of optimizing your website and its content to rank higher in search engine results pages (SERPs) for specific keywords and phrases. The goal of SEO is to increase organic traffic to your website and improve its visibility in search engines like Google. SEO includes various tactics like keyword research, on-page optimization, content creation, and link building.

SEM, or Search Engine Marketing, refers to the paid advertising that appears at the top of search engine results pages (SERPs). SEM involves paying to place your ad in front of users who search for specific keywords and phrases related to your business. The most common form of SEM is pay-per-click (PPC) advertising, where you only pay when someone clicks on your ad.

In summary, SEO is a long-term strategy that involves optimizing your website and content to improve its visibility in organic search results, while SEM is a paid advertising strategy that involves paying to have your ad appear at the top of search engine results pages. Both SEO and SEM can be effective in driving traffic to your website and generating leads, and many businesses use a combination of both strategies to achieve their digital marketing goals.
