SEO What is SEO? SEO stands for Search Engine Optimization — the process of improving your website to increase its visibility on search engines like Google. When you search for something online, Google instantly analyzes hundreds of factors (called ranking factors) to decide which websites deserve to appear at the top of the results. SEO involves optimizing your website’s content, structure, and performance to align with these ranking factors — so when people search for products or services related to your business, your website shows up on page one.
