How to see what keywords a website is using?

To see what keywords a website is using and ranking for, you can combine direct web inspection techniques with specialized third-party SEO competitive analysis software. For quick on-page inspection, open any webpage, right-click to select "View Page Source," and search for key HTML elements like the `<title>` tag, meta descriptions, `<h1>` and `<h2>` headers, and image alt text to spot targeted phrases. To discover thorough keyword data across an entire domain, use professional SEO tools such as Semrush, Ahrefs, Moz, or SE Ranking. By entering any competitor domain into these tools, you get detailed reports showing every organic keyword the site ranks for in Google search, along with current ranking positions, estimated monthly traffic volume, keyword difficulty, and historical keyword trends. Additionally, Google's free Keyword Planner tool can scan a URL to extract key topic categories.
