Review Questions

• How do search engines influence user behavior and information retrieval on the internet?
  • Search engines significantly shape user behavior by determining which information is readily accessible based on their algorithms. Users often rely on the first page of search results, which means that the ranking system directly affects what content they encounter. This reliance can lead to an information hierarchy where certain websites dominate visibility, impacting how users perceive credibility and relevance in their searches.

Businesses invest heavily in SEO techniques to ensure their sites are optimized for visibility. This competition drives companies to create high-quality content and enhance user experience, fundamentally changing marketing approaches as brands seek to adapt to algorithm updates and shifts in user behavior.
• Evaluate the ethical considerations surrounding search engines and their data collection practices.
