SEO is a process to optimize a website to rank highly for target keywords. 82% of internet experiences start with a search, and 70% of clicks are on organic search results. SEO involves on-page optimization like keyword research, content creation, and HTML improvements. It also involves off-page optimization like building relevant backlinks from social media and high-quality sites. The goal is to understand users' intent and provide helpful on-topic content to search engines and visitors.
