SEO stands for **Search Engine Optimization**. It’s the practice of improving a website to increase its visibility in search engine results, like Google. The goal is to rank higher for relevant search terms, which can help drive more organic (non-paid) traffic to the site.
SEO involves several strategies, including keyword research, on-page optimization (like using proper titles and meta tags), content creation, improving website speed, and building backlinks. It's an ongoing process because search engine algorithms are constantly evolving.
