Search terms are the specific words or phrases that users enter into a search engine, like Google, to find information online. These terms help the search engine understand what the user is looking for, allowing it to return relevant results. For example, if someone types "best pizza places," the search engine will look for websites that contain information about popular pizza restaurants. Understanding search terms is crucial for businesses and content creators, as it helps them optimize their websites for better visibility. By using relevant search terms, they can attract more visitors and improve their chances of being found by potential customers.
