SEO, or search engine optimization, is the process of optimizing a website to improve its visibility and ranking in search engine results pages (SERPs). The goal of SEO is to increase the quantity and quality of organic (non-paid) traffic to a website by improving its relevance, authority, and usability for both search engines and human users. This is achieved through a combination of technical, on-page, and off-page optimization techniques, such as keyword research and optimization, content creation and optimization, link building, and website structure and design improvements. By improving a website’s visibility and ranking in SERPs, SEO can help businesses attract more qualified leads, increase brand awareness and credibility, and ultimately drive more conversions and revenue.
