Many consider search engine optimization (SEO) and digital marketing to be synonymous. However, they have two separate definitions and are entirely separate. There are many ways in which SEO and digital marketing function similarly and today they work in tandem. An SEO company is hired to optimize a website so that its position in search engine results is improved. They will use a wide variety of strategies and SEO best practices to achieve higher rankings in the SERPs. SEO is actually a subset of digital marketing and there are many who would define an SEO specialist as one who integrates digital marketing and SEO best practices to achieve their goals.
