There's no universal percentage-of-revenue rule that actually fits every small business — a brand-new business and an established one with years of customer data need completely different budgets. What matters more is spending in the right order.
Foundations first, no matter the budget size
A working website and a complete Google Business Profile come before anything else, regardless of how much you have to spend overall. Both are relatively low-cost, and skipping them to fund ads instead means paying to send traffic somewhere that can't convert it.
Why ad spend without a foundation gets wasted
Paid ads amplify whatever they point to. Point them at a site with no clear next step, or a Google listing that's incomplete, and the spend produces clicks that go nowhere — the most common way new businesses burn through an early marketing budget without seeing results.
SEO and ads aren't competing for the same budget line
Ads buy visibility instantly, but only for as long as you keep paying. SEO takes longer to show results but keeps working afterward without ongoing spend. Treating them as an either/or choice usually means missing the benefit of both — most businesses do best sequencing SEO early and layering ads on top once there's something solid to send traffic to.
Measure against leads, not vanity metrics
Impressions and likes feel like progress but don't pay the bills. Track what each channel actually produces in real inquiries or sales, and let that — not a fixed percentage of revenue — guide where the next pound of budget goes.
A simple way to sequence it
Start with the free or low-cost foundations, add local SEO once the basics are solid, and bring in paid ads once there's a website and process that can actually convert the traffic they'll send. Scaling any one of these before the step before it is solid usually means wasted spend.
Common questions
There's no universal number — the right amount depends on what stage your business is at. A brand-new business often needs less spend and more foundational setup; an established one with a working funnel can spend more effectively on ads.
