Keywords or search terms are words or phrases that users enter into search engines to find information on a specific topic. Websites aim to rank for relevant keywords to be discovered by their target audience.
Keywords are essential for SEO because they act as the bridge between user search queries and the content provided on a website. By integrating keywords into their content, website owners signal to search engines that their page offers relevant information on the searched topic, thereby enhancing the chances of ranking for those terms.
