Short answers to what owners ask me most often.
Small businesses typically spend 5-15% of annual revenue on marketing. The right number depends on your industry, your margin, and how long you have been marketing at all: a new company building a name needs the top of that range, an established one can live at the bottom. The Don Marketer calculator gives you your own range in two minutes.
Work out your break-even: divide one by your margin. At a 35% margin the break-even is 2.9: every dollar of ad spend has to return $2.90 in revenue just to break even. Anything above that is profit. Brand pays back slower than performance advertising; count in months, not days.
Both, in a ratio that shifts with your stage. In year one most of the money goes into performance, because you need sales fast and you are still learning what works. After a few years the weight moves toward brand, which quietly makes every later order cheaper.
Up to roughly $1,500 a month one capable person or a freelancer is enough. Between $1,500 and $7,000 a month a single full-service agency makes sense. Above that, channel specialists plus someone in-house to steer them.
