The hours that digital marketers work will vary based on the scope of their work. It is also important to remember that some people work faster than others, so for the same time period some people might complete twice the amount of work.   Although, what is more important to consider is whether the hours being put in are generating results or not. Digital marketing has access to loads of data so you can see whether something is working or not pretty quickly.    If the marketing activities are generating new sales, more leads & an increase in customer flow then the importance about hours becomes less of an issue. The focus should be on outcomes delivered.
