SEO vs SEM: What is the difference?

SEO (Search Engine Optimization) is a process used to prepare websites to rank high in search results and gain more organic traffic, while SEM (Search Engine Marketing) comprises tactics that allow you to promote your website online. SEM includes SEO, but goes beyond that; it involves other methods that can get you online traffic like PPC advertising. Both SEO and SEM are important for any digital marketing strategy – you just have to figure out on what technique to focus your marketing efforts based on your business goals.
