What is search term? How to use in English

The term "search term" originated in the context of online search engines, which emerged in the early 1990s. As these search engines became increasingly popular and sophisticated, web users began to realize that the keywords they used to search for information online could have a significant impact on the results they received. At first, people simply referred to these keywords as "search words" or "query terms," but as the practice of optimizing websites to rank higher in search engine results became more common, the term "search term" began to gain traction. This new term better represented the idea that these keywords were actively being sought out by users in the hope of finding specific information or items online. Today, the term "search term" has become a widely recognized and integral part of online search and digital marketing, and can be found in various contexts, from search engine optimization (SEO) to pay-per-click (PPC) advertising and content marketing strategies. Whether it's a long-tail keyword for an e-commerce site or a specific phrase for a research paper, "search term" continues to play a crucial role in helping people find what they're looking for online.
