A detailed competitive SEO analysis is required to benchmark and optimize a new website currently under development. A knowledgeable freelancer is requested to utilize Semrush's intelligence to comprehensively evaluate the organic visibility of two competitor domains. Specifically, the top performer's keyword strategy, backlink profile, and on-page content should be identified and contrasted with the weaker performer. Insights on their relative strengths and weaknesses must be presented, highlighting the ranking factors and opportunities where the latter is lacking. A succinct strengths-gaps-recommendations report is to be delivered, outlining the target keywords, backlink opportunities, and ideal on-page optimizations that would best position the new website for search engine success against its competitors. The goal is to provide advantageous keywords, contents and backlinks to use in my new website under development.
