1. Web Search Engines<\/strong><\/h2>\n\n\n\n

A web search engine<\/strong> is a software system that crawls, indexes, and ranks publicly available content across the internet. The most widely used type of search engine, web search engines process billions of queries every day \u2014 making them the primary gateway through which people discover information online.<\/p>\n\n\n\n

How Web Search Engines Work<\/strong><\/h3>\n\n\n\n

Web search engines work in three stages. First, automated bots called web crawlers continuously scan web pages, following links and collecting data on content and structure. Second, that data is organized into a searchable index \u2014 a massive database of web content. Third, when a user submits a query, a ranking algorithm evaluates indexed pages based on authority, relevance, and user intent to return the most useful results. Artificial intelligence and machine learning now play a central role in all three stages, making modern web search significantly more accurate than early keyword-based systems.<\/p>\n\n\n\n
