SEO (Search Engine Optimization) and SEM (Search Engine Marketing) are two key components of digital marketing that are used to improve a website’s visibility on search engines.

SEO involves optimizing a website’s content and structure to improve its ranking on search engine results pages (SERPs) for specific keywords and phrases. This is done by making changes to the website’s content, structure, and code to make it more appealing to search engines. The goal of SEO is to increase the website’s organic traffic by improving its visibility on search engines.

SEM, on the other hand, is a form of online advertising that involves paying for advertising space on search engines to improve a website’s visibility. This is usually done through paid search advertising, where businesses bid on keywords related to their products or services, and their ads are displayed at the top of the search results pages when those keywords are searched for. The goal of SEM is to drive targeted traffic to the website by reaching potential customers who are actively searching for products or services similar to what the business offers.

In summary, while SEO focuses on improving a website’s ranking in organic search results, SEM involves paying for advertising space on search engines to drive targeted traffic to a website. Both SEO and SEM are important components of a digital marketing strategy and can work together to increase a website’s visibility and drive traffic.
