Website optimization, also known as search engine optimization (SEO), is the process of improving a website to drive business goals through controlled experimentation. Some key benefits of optimization include low cost results from organic listings, increased traffic, improved brand credibility, and higher returns on investment. Proper optimization techniques involve ensuring relevant and high-quality content, optimizing internal linking, meta tags, images, and domain names, while avoiding negative practices like keyword stuffing and duplicated content. Optimization can help take a business to the next level by bringing in thousands of additional visitors.
