Search Engines and Directories

What is the difference between search engines and directories?

Search engines are large powerful databases that rely on automated search agents called webbots, crawlers or spiders. The best example of this today is Google. The main way to differentiate between search engines and directories is to think of a directory simply as a list of websites in a database. This list is stored in a database so that it can be accessed and maintained quickly and easily. Human editors actually go to your website, review it and add it to their main list of sites. These human editors often change titles and descriptions, and place the website in the appropriate category at their discretion.Check your answer
