The main advantage of crawler-based search engines over directories is their ability to automatically index vast amounts of web content in real-time, providing users with up-to-date and comprehensive search results. While directories rely on manual submissions and human curation, which can be time-consuming and may miss newer or less popular content, crawler-based systems can continuously scan the web, ensuring that users have access to a broader range of information quickly. This efficiency allows crawler-based search engines to handle the dynamic nature of the internet more effectively than static directories.

The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. (Source: Wikipedia)
