Media spend vs management fee
The media spend goes to Google, Meta and the like — you set it, and it can be anything from a few hundred to six figures a month. The management fee goes to the agency or person running it. Mixing these up leads to nasty surprises; always separate them when comparing options. There's a third bucket people forget: tooling and setup. Call tracking, landing-page builders, analytics, and the up-front work of structuring an account all cost something, and a quote that bundles them invisibly is harder to compare than one that lists them. Ask for the breakdown in writing.
How agencies charge
Three models dominate, and each fits a different situation. Percentage of ad spend (often 10–20%) is simple and scales with the account — but it quietly rewards the agency for spending more, not for spending well, so it suits stable, larger budgets where the percentage lands on real work. A flat monthly retainer (frequently $1,500–$5,000+ for mid-market) is predictable and the incentives are cleaner, which makes it the default for most growing businesses. Performance-based fees tie pay to leads or revenue and sound ideal — but they need agreed, trustworthy tracking and a lead the agency can actually influence, or you'll argue every invoice. Many setups blend a smaller base retainer with a performance kicker. Whatever the model, the question that cuts through it is the same: what work, specifically, does this fee buy each month?
What drives cost per click
Your market's competitiveness sets the floor on a click — a few cents in some niches, well over $50 in legal or insurance, where one converted client is worth a fortune and everyone knows it. But you don't pay the market rate by default. Better keyword targeting, tighter ad copy, and a relevant landing page raise your Quality Score, and a higher Quality Score lowers what you actually pay per click for the same position. That's the lever good management pulls — not magic, just the unglamorous work of relevance — and it's why two businesses in the same auction can pay very different prices.
Where the budget actually goes wrong
The expensive mistake isn't paying too much per click. It's paying for the wrong clicks. An account with no negative keywords pours money into searches that were never going to buy. A budget set too low gets spread across too many keywords, so nothing collects enough data to optimise — small budgets win by going narrow, not wide. And spending hard to send traffic to a slow or vague landing page wastes the click after you've already paid for it. So before raising a budget, the better first question is whether the current one is being spent cleanly. Usually it isn't.
