Link building is an essential factor that impacts your site's ranking and traffic. By using link building for competitive benchmarking, you can evaluate how your link profile compares to your competitors' in terms of quantity, quality, diversity, and relevance, as well as discover new link opportunities and identify link threats. To begin, you must identify your main competitors with tools such as Google's search results, SEMrush, or Ahrefs. Then, analyze their link profiles with tools like Moz's Link Explorer, Majestic, or Ahrefs to collect data on their backlinks. Afterward, use Link Gap Analysis or Content Gap Analysis to find out which sites or pages are linking to your competitors but not to you, and which topics or keywords are generating more links for them than for you. Additionally, Disavow Tool or Link Detox can be used to identify any links that are harming your site's reputation or ranking. Lastly, use Link Building Planner or Link Building Assistant to plan and execute your link building campaigns based on the competitive benchmarking results. Furthermore, use Link Tracking or Link Alerts to measure and track your link performance and progress.
