It analyzes the content and metadata of each page, extracting keywords and indexing them for future retrieval. The spider’s purpose is to update search engine databases, ensuring that search results are relevant and up-to-date. With incredible speed and efficiency, these web crawlers enable search engines to deliver accurate and comprehensive search results to users worldwide.
