I recently came across the article "Plan Your Website, Save Money and Time" and decided to share it with you.

The author introduces the article:

Planing your website will save you money, time and get you the website you want. Without the bricks (layout, content, photo's etc) the web design agency can't build your website successfully. Provide them the material and you will have more control over the web project.

As indicated here, planning the content of your website is the most important thing you do to prepare for building a site.

Content, content, content is the mantra for website planning and building. Once you know what you want in your website (content) then you need to allow the website builder some time to design a website for you. Don't try and do her/his job for her/him.
