Search engines like Google use sophisticated
algorithms to crawl and index the vast amount of information available on the web. This process can be broken down into three key steps:
Crawling: Search engine bots, known as crawlers or spiders, explore the web by following links from page to page. They collect information about each page, including the content, keywords, and links.# A simplified example of a crawler using Python (not a production-ready crawler) import requests from bs4 import BeautifulSoup def crawl_website(url): response = requests.get(url) soup = BeautifulSoup(response.content, 'html.parser') links = soup.find_all('a', href=True) for link in links: print(f"Found link: {link['href']}") crawl_website(link['href'])
Indexing: The information gathered by the crawlers is stored in a massive database known as an index. This index allows search engines to quickly retrieve relevant results when a user enters a search query.Ranking: When a user enters a search query, the search engine uses its algorithms to rank the most relevant pages from its index. These algorithms consider various factors, including the quality of the content, the number and quality of backlinks, the user experience, and the relevance of keywords.
