Website Design – How abstract / specific are your wireframes?

We are a small web design team that has been overhauling our workflow and wondering how you work with wireframes.

Do you use wireframes and if so, how abstract or specific are they? Are you trying to use real content (text, images, …) or just rectangles and blind text? Why do you decide for that?

We are happy to hear from them! Cheers and thanks in advance! 🎉
