What Is SEO and How Does It Work?

SEO, or search engine optimisation, is the work of getting a website to appear when people search Google for what it offers. It works by improving three things Google cares about: whether your site is technically sound enough to be crawled and indexed, whether your content genuinely answers what people search for, and whether other sites and signals suggest you are trustworthy. When those line up, Google ranks your pages higher, and higher rankings bring clicks from people already looking for your product or service. Unlike ads, SEO builds an asset that keeps working after you stop paying. It takes months, not days, because Google needs time to crawl, assess, and trust the changes you make.
