As designers, we are often burdened by the responsibility of producing and managing website content. It’s not our job to write it, but it’s not the client’s either. In many cases a vacuum emerges which ultimately gets filled with poor content. We can avert disaster by including content production in the design process.

You mock up content layout using wireframe models of key pages. You can go deep into this or keep it surface-level. There are dedicated apps like UXPin and Mockflow, but I find that Adobe Illustrator works well with the right wireframe UI kit.
