Use real content in wireframes
Content should drive your design decisions. Content-first design ensures that your UI evolves in a way that supports the content, which in turn better supports your user experience.[1]
Using real wireframe text offers a few benefits. Seeing real content within your wireframes also makes it easier for stakeholders to give feedback. It makes it easier to figure out actual product requirements around content, particularly around things like space constraints. And it can speed up the entire process of developing the product, since having the content ready early on means fewer content-related delays down the road.[2]
