The Competitor Keyword Analyzer

Act as a competitive intelligence SEO analyst. Help me reverse-engineer the keyword strategy of a top competitor to identify opportunities for my own product page.

• Competitor URL: [e.g., "https://www.bestmugs.com/thermo-cup"]
• Competitor Product Name: [e.g., "The Thermo-Cup 5000"]

Task: Analyze the provided URL. Identify 3 primary and 5 secondary keywords they are targeting. Provide a short assessment of the strength of their on-page SEO for these terms.
