When you have your wireframes built, you should put the into a prototype format. There are dozens of programs out there that will take what you’ve drawn and link them to other pages or layers to give the illusion of a fully functioning site. This is typically the job of the researcher, to gather some of the similar users/customers you used for the research/persona stage and bring them in (or digital meet) to test your prototypes. What you should end up with is a long list of things you failed at or didn’t think about when you did your wires. This can be depressing to the designer that has a lot of their ego invested in their work because you will likely be disappointed at how unusable some of your work ends up being. Back to the drawing board because what you’ve learned will be essential to the continual improvement of your design. Complete as many cycles of this Wire-test-learn cycle your budget/team/leadership/deadline can tolerate as it is the most valuable process here.
