The Sparkes Series

The real economics
of performance marketing.

Sparkes is written by Kevan Baker — owner of Firestarter. Every post names a number, cites a receipt, or calls a gap between what the agency reports and what actually lands in the bank. No fluff. No filler. The ledger is open.

I locked my phone in a hotel safe in Bali for a week and let the agents run the business.

Seven days, phone in the safe, ads at maintenance. 31 inbound calls answered, zero missed, 21 leads booked, one escalation. The full log, dated — including the one she got wrong.

95% of AI pilots produce zero P&L impact. The 5% start somewhere else.

Most AI investments are decisions in search of a problem. The 5% that pay back start with the question most businesses skip. A worked example from a real P&L.

The cost of slow: what late replies and missed calls really cost.

One mid-sized business. $5.2 million a year bleeding out — every dollar of it caused by being slow. The receipts, the ledger, and the number nobody invoices you for.

The custom CRM problem: busy is not the same as paid.

Every business builds its own CRM. Most build a to-do list with a database. The difference between busy and productive is a ledger you can actually read.

60% of small businesses now use AI. Only 23% got anything back.

The gap between buying a tool and building a system. Why most AI spend produces nothing measurable, and where the 23% found their return.

Google rewrote the deal — who keeps the clicks?

The shift from ten blue links to AI Overviews changes the economics of search advertising. The clicks still happen. They just don't land where they used to.
