Search Engine Bot
A Search Engine Bot is an automated software program used by search engines to systematically discover, analyze, and store information from websites across the internet.
Definition
A Search Engine Bot, also known as a web crawler, spider, or indexing bot, is a type of automated system that visits web pages, reads their content, and follows links to discover new URLs. It collects page data such as text, metadata, and structure, then sends this information back to search engine systems for indexing and ranking purposes. Search engines use these bots to understand what each page is about and determine how relevant it is for user queries. Without crawling, web pages cannot be indexed or appear in search results. These bots also help maintain updated search databases by repeatedly revisiting pages and detecting changes over time.
