Competitor Friction
Google Ads agency hidden fees explained
If your agency charges a percentage of spend, they earn more when you spend more, not when you profit more. That is a structural conflict of interest.
Most ecommerce brands paying £30k+ per month in ad spend are overpaying their agency by 30-50%. Not because agencies are dishonest - but because percentage pricing, tool markups, and scope limitations are the industry default. They do not have to be.
The Problem
Where agencies hide their fees
These are the most common fee structures designed to extract more money from you without delivering more value.
Percentage of Spend Pricing
Your agency earns more when you spend more, regardless of whether that spend is profitable. Their incentive is volume, not margin. At 10-15% of spend, a £50k/month ad budget means £5k-£7.5k in fees - and they have every reason to push that to £80k.
Media Arbitrage
Some agencies buy media at one price and bill you at another, pocketing the difference without disclosure. This is more common than you'd think - particularly with Display and YouTube placements where pricing is opaque.
Tool and Tech Markups
Third-party tools billed at 2x or 3x cost. A feed management tool that costs £200/month gets billed to you at £600/month as part of 'technology costs.' You pay for their stack, often without knowing the real price.
Scope Creep Charges
Additional fees for reporting, strategy calls, creative iterations, or feed updates that should be included in your retainer. 'That's outside our standard scope' is the most profitable sentence in agency English.

The Bottom Line
£45,000/year saved - and that's before accounting for the performance improvement that comes from having an agency incentivised by your profit, not your spend.
The Real Problem
How percentage pricing changes agency behaviour
The hidden cost is not just the fee - it is the decisions your agency makes (or avoids) because of how they are paid.
Google recommends increasing budget by 30%
% of Spend Agency
Accepts enthusiastically - their fee increases by 30% too. More spend = more revenue for them, regardless of your margin.
Fixed-Fee Agency
Evaluates whether the incremental spend generates marginal profit. Often rejects the increase because the diminishing returns curve means the extra spend loses money.
Account is performing well at current spend
% of Spend Agency
Finds reasons to increase budget - 'We're leaving impression share on the table.' Their incentive is always more spend.
Fixed-Fee Agency
Focuses on optimising margin within the current budget. May even recommend reducing spend if the bottom portion is unprofitable.
Non-brand campaigns are loss-making
% of Spend Agency
Keeps them running - turning off £15k of spend means losing £1.5k-£2.25k in monthly fees. They'll find reasons to keep spending.
Fixed-Fee Agency
Recommends pausing or restructuring immediately. Their fee doesn't change, so the only incentive is getting you the best result.

What are common hidden fees in PPC agency contracts?
TLDR: Percentage-of-spend pricing, media arbitrage, tool markups, and scope creep charges are the big four.
The four most common hidden fees are: percentage-of-spend pricing (your agency earns more when you spend more regardless of profit), media arbitrage (buying media at one price and billing another), tool markups (third-party tools billed at 2-3x actual cost), and scope creep charges (extra fees for reporting, strategy calls, or feed updates that should be included).
