Off-Page SEO: Involves external efforts to build authority and traffic. Prioritize quality over quantity, a few strong backlinks beat many weak ones.

Tools: Use Google Search Console (free) to monitor indexing, Google Analytics for traffic, and paid tools like SEMrush or Ahrefs for deeper insights.
