Let's address the elephant in the room: someone told you marketing should be "free," and that person was lying. Not maliciously! But still lying. After working with hundreds of small businesses, Enji has seen the pattern: the businesses that invest smartly in marketing are the ones that actually grow. The ones trying to do everything for free? They're usually the ones still struggling two years later.
Now, don't panic—you don't need to blow your kids' college fund on Facebook ads. The 6-12% rule gives you a starting point, but your actual number depends on your situation. Got a bakery or online store? You're probably looking at the higher end because you need fresh customers constantly. Running a consulting business or photography studio? You might get away with 5-8% if you're crushing it with referrals and SEO.
Here's the math that actually matters: take your monthly marketing spend and divide it by the number of new customers you got. That's your customer acquisition cost, and if it's higher than what those customers spend with you... well, Houston, we have a problem.
The key insight? Don't expect instant results. Give your marketing about 90 days to show you what it can do, and track the numbers that actually matter to your business growth.
