Business directory instead of website !?

Time and again in my daily work I experience that entrepreneurs take this point of view. “I don't need a website, I'm in the yellow pages, that's enough”.
In times when there is a multitude of networks such as Facebook, Twitter and Co., many entrepreneurs are overwhelmed. These channels consume a lot of time and effort because they have to be effectively maintained. The thought of having your own website is a long way off.
Because there are so many networks, your own website is essential. Together with a blog, it forms your control center in the global data network for your own company.
You present your services to interested parties on your own website. In the company blog you live your active corporate communication. Topics are placed here that show your company and its processes. At the same time, you can actively exchange ideas with the reader, which can also expand to other networks such as Facebook. Thus, your website is the first point of contact for your company.
