SEO (Search Engine Optimization) and SEM (Search Engine Marketing) are both strategies used to improve a website’s visibility on search engines. However, they are not the same thing.
SEO is a set of techniques and best practices that are used to optimize a website’s content and structure to improve its ranking in search engine results pages (SERPs). The goal of SEO is to increase organic traffic to a website by making it more visible and attractive to search engines.
SEM, on the other hand, is a broader term that refers to any marketing activity that involves improving a website’s visibility on search engines. This can include SEO, but it can also include paid advertising, such as pay-per-click (PPC) ads. The goal of SEM is to increase website traffic through any means necessary, including paid and unpaid methods.
In summary, SEO is a specific technique that is focused on improving organic search rankings, while SEM is a broader term that encompasses a variety of tactics for increasing website traffic through search engines.
