While Search Console shows how people find your site through search, Google Analytics shows what happens after they arrive — how many visitors you get, which pages they visit, how long they stay, and what actions they take (like filling a form or making a purchase). For SEO purposes, key metrics to watch include organic traffic (visitors from search engines), bounce rate, and average session duration. Understanding these numbers helps identify which pages are performing well and which need improvement, connecting your SEO efforts to real user behavior and business outcomes.
