In my experience with non tech clients, the website is built using Wordpress, hosted by the agency, and presented in a board room. The presenter will connect a newish MacBook into the projector after lots of fuss about the right dongle type and proceed to click around. The decision maker at the company will verify items against their memory and usually things that users do not care about, like they will ask who agreed to have a photo of the red car instead of the blue car because if they recall everyone had agreed to the blue car. Oh it was the red car after all. Really, because the blue car looked better. Oh it was a placeholder image of a different racing team. Oh well in that case it’s fine.
