When encountering something new, our first reaction is to ask questions and understand what it is and what it is used for. So what is SEO?
SEO stands for **Search Engine Optimization**. Its function is to increase effective traffic, optimize keywords, and improve search rankings.

To be more specific, SEO refers to the process in which search engines crawl websites into their index databases according to their built-in algorithms, then return the websites with the highest traffic for targeted keywords to users as search results.

In simple terms, SEO means optimizing websites in line with search engine rules, sorting them by rational selection, and improving their rankings on Baidu, Google, and other platforms, thereby bringing more traffic to the site.

In short, it is an SEO marketing method built on search engines, providing an interactive marketing platform for web pages. Through competition among websites, it helps them take a leading position in the industry and increase brand revenue.

After a series of operations on search engines, we further optimize and manage information. In other words, SEO acts like an information filter. It inspects and optimizes web pages crawled by search engines both internally and externally, improving the organic ranking of website keywords in search engines.

To summarize what SEO is in daily language:
SEO is a technique that acts as a bridge between search principles and user experience. Following search engine rules, it improves keyword rankings based on how search engines operate, thereby increasing website visibility and achieving profitable goals.
