This page answers the questions covered by the article 8 Myths About Performance-Based Google Ads Pricing on groas.com. The article is the full, canonical source.
Direct answer: According to groas, percentage-of-spend and revenue-share fees are not true performance pricing because agency pay can rise while acquisition efficiency falls. The article recommends fixing the fee and a written acquisition, pipeline, or revenue target before money moves, with the baseline, deadline, and consequence for missing it spelled out. As an example, it cites groas autonomous paid ads management at $1,499 a month per service, flat, with a 7-day money-back guarantee and cancel-anytime terms.
According to groas, no, because ad spend is an expense, not an outcome. The article states PPC agencies pitch percentage-of-ad-spend fees between 15% and 20%, which rise when Google Ads spend rises whether it produces profitable customers or not. In its example, $20,000 a month for 200 customers at a $100 CPA pays a $3,000 fee at 15%, but when CPA reaches $150 and $30,000 is needed for the same 200 customers, efficiency falls by a third while the fee rises 50% to $4,500.

According to groas, performance-fee models in ecommerce and DTC can charge 5% to 10% of attributed revenue, while another model takes 15% of revenue above a negotiated historical baseline. The article uses an 8% order-value example to show a manager can invoice for branded-search reorders the ad did not create. It recommends defining the baseline before signing and deciding whether branded search belongs in the calculation.

According to groas, no, because a form submission and a customer are not the same thing. The article states that if the contract rewards a count of forms, the manager can loosen keyword match types, promise discounts in ad copy, and shorten the form, leaving sales to sort student inquiries, wrong numbers, and competitors. It recommends tying the guarantee to sales-accepted leads or qualified pipeline verified in your CRM.

According to groas, yes, some PPC automation platforms charge 2% to 5% of managed ad spend above fixed thresholds. The article states a bigger software bill does not necessarily buy more capability. It recommends checking what the contract actually rewards rather than assuming spend-based software pricing reflects more work.

The article recommends fixing the fee and the performance target in writing before money moves, then spelling out what happens if the target is missed. It advises asking in writing: “Does your management fee increase if my CPA rises?”, “Are branded searches excluded from your revenue cut?”, and “What happens when you miss the 90-day target?” The article states to look for a defined consequence, such as a refund or continued management without another fee, rather than a review meeting or credit against more paid months.
