A good budget for digital marketing is one that is sustainable for your business. You could ask 10 marketing people how much they could spend and they will all give you different answers, it is easy to spend a budget of $100, $6,000 or $600,000 on digital marketing.   The smart way to work out your budget is to set it as a % of your revenue (or in rare cases % of profit) so that it is relative to the business being generated.   You will read lots of advice about what that percentage should be and it could be anything between 1% and 20% with a lot depending on how well established your business is.   Once you play around with your %'s you have to look at what that means in real dollar terms. If you are launching a new brand and your forecasted sales means a marketing budget of $5,000 then this might be ok for a local business operating in a suburb but more difficult for a brand being launched online that will sell to the world.   A digital marketing consultant will be able to help you work out how to stretch that budget to get maximum exposure and return on investment. Smart business owners might even put a bonus scheme in place for the marketing person.
