When SEO began, it was mostly about optimizing landing pages on a desktop. However, as new technologies emerged, things became complex. SEO evolved rapidly to cater to the fast-paced world and the high demand for content from the audience. The most drastic changes happened with the arrival of smart devices like mobiles. While many of the basic tools SEO uses are still the same like keywords, regularly updated content, and linking; the current SEO now includes much broader considerations including mobile search, UX, and social media profiles.
