Here is an A/B test that shows that testing words can be important on all types of pages. Too often, word testing is perceived as something for buttons, action, conversion. In the best of cases, also links and navigation will come into consideration for word testing.
This test in Which Test Won shows that words can affect seriously the outcome in what in the case analysis is described as top-anxiety pages. That is a very good choice of words: pages where the customer is worried about the consequences of his next action. Where the customer is more or less asked to fly blind, to trust the next step – or where he considers the risk of an unpleasant surprise. Where he is worried about the happy ending of his top task of the moment.
