'How much should I spend on marketing?' is one of the most common questions. The right answer varies, but a sensible framework is possible: spread money across the things that return the most.
A common starting rule: growing businesses allocate 7-15% of revenue to marketing. But more important than the number is measuring what your spend brings back. Start small, scale what works.
All ads: traffic dies when money stops. All SEO: you wait months. The smart split funds ads that sell today and content/SEO that builds tomorrow.
Bottom line: start small, measure every spend, scale winners. A balanced budget saves both today and tomorrow.
