Web spiders, also known as web crawlers or web robots, are automated programs designed to browse the internet and collect information from websites. They systematically navigate through web pages by following links, gathering data such as text, images, and metadata. This information is then indexed to help search engines like Google provide relevant search results to users. These spiders play a crucial role in maintaining the functionality of the internet. By indexing content, they enable users to find information quickly and efficiently. Without web spiders, search engines would struggle to organize and retrieve the vast amount of data available online.
