Touchpoint analysis is the systematic evaluation of every customer interaction with your brand. It maps the customer journey from awareness (Google ad, word-of-mouth) through purchase (checkout, payment) and retention (email, support) and optimizes each interaction for conversion, satisfaction, and lifetime value. A single weak touchpoint can kill conversions. If your landing page is slow, users bounce before reaching the offer. If support is slow, customers churn. Touchpoint analysis finds these weak links and prioritizes fixes.
