SEO stands for Search Engine Optimization, and it's crucial for increasing a website's visibility in search engines. By optimizing website content, structure, and technical aspects, businesses can improve their rankings on search engine results pages (SERPs). SEO practices, including keyword research, link building, and improving site speed, enhance user experience while attracting organic traffic. As most users seldom explore beyond the first page of search results, effective SEO strategies can significantly drive audience engagement, leading to higher conversion rates. Ultimately, SEO is vital for online success and maintaining competitiveness in the digital landscape.
