The hidden costs of cheap PPC management

The appeal of a low management fee is obvious. Paid search spend itself is already a significant cost, and keeping the management overhead low seems prudent. The problem is that the quality of management has a direct impact on how efficiently the ad spend performs. Poor management does not just mean slower growth - it means active waste.

The waste that accumulates invisibly

A Google Ads account that is not actively managed starts degrading within weeks. Negative keywords are not added as search term reports reveal irrelevant queries. Budget continues flowing to poor performers. Conversion tracking errors go unnoticed. Ad copy goes stale. Landing pages with high bounce rates are not flagged. Each of these individually might represent 5 to 10 percent waste. Collectively, across a year, they can mean 30 to 40 percent of the total ad spend has been wasted on traffic that would never convert.

The false economy of percentage-of-spend fees

Be cautious of agencies charging a percentage of ad spend as their fee. Their revenue increases when your spend increases, regardless of whether that spend increase is justified by performance. The incentive is to recommend spend increases, not to optimise efficiency. A flat management fee or value-based fee structure aligns agency incentives with client outcomes more cleanly.

What adequate management actually involves

A properly managed Google Ads account at a minimum requires: weekly search term reviews and negative keyword additions, weekly performance checks with anomaly investigation, monthly strategic review of bidding, targeting, and budget allocation, regular ad copy testing, landing page performance monitoring, and conversion tracking verification. These are not optional activities - they are the baseline for competent management. If your agency fee is so low that it cannot cover this time, these things are not being done.

How to evaluate what you are getting

Ask for a detailed account of what actions were taken on your account in the last 30 days. Any competent agency should be able to provide a log of optimisations with rationale. If the answer is vague or the log is thin, that tells you what you need to know. The fee you pay should reflect the work being done. If it does not, the shortfall is being made up somewhere - usually in the performance of your campaigns.
