Transparency and Ownership
The most important thing to confirm is that you own everything — your Google Ads account, your data, your conversion tracking, and your historical performance. Some agencies run campaigns inside their own account so that leaving means starting from scratch. That's a red flag. You should always have full visibility into where your money goes and what it produces.
Transparency extends to reporting. You want to see real metrics tied to your business — leads, sales, cost per acquisition — not just clicks and impressions that look impressive in isolation. A strong agency reports in terms of outcomes and explains the reasoning behind what changed and why.
Focus on the Right Metrics
Anyone can drive traffic. The job of paid search is to drive profitable traffic, which means the conversation should center on cost per acquisition, return on ad spend, and lead quality — not vanity metrics. If an agency leads with click-through rates and impressions while staying quiet on what those clicks cost you in real outcomes, push harder.
Good paid search also respects the full path. Sending traffic to a weak landing page wastes the spend, so a capable agency thinks about conversion, not just the click. The best results come when ads, landing pages, and follow-up are treated as one connected system rather than separate jobs.
Red Flags to Watch
Be wary of guaranteed results or promises of a specific position or return — paid search is competitive and shifting, and no honest agency can guarantee an auction outcome. Be equally wary of long lock-in contracts paired with vague reporting; if the work is good, the results should keep you, not the paperwork.
Other warning signs include set-and-forget management, where campaigns are launched and rarely touched, and a refusal to explain strategy in plain terms. Paid search rewards constant testing and refinement. If no one's actively in the account improving it, you're paying a management fee for autopilot.
A True Partner, Not Just a Vendor
The best paid search relationships feel collaborative. The agency understands your margins and what a customer is worth, so bids and budgets are set around profit rather than raw volume. They bring ideas, flag opportunities, and tell you when spending more won't help — which is the mark of someone optimizing for your outcome, not their billings.
CMG Media approaches paid search as part of a broader growth strategy, working with a select number of clients on monthly retainers. That means campaigns are coordinated with your site, SEO, and overall goals rather than run in a silo — and managed actively as a partner invested in the result.
Key takeaways
- Insist on owning your ad account, data, and tracking — never run campaigns inside an agency's account.
- Judge performance on cost per acquisition, return on ad spend, and lead quality, not clicks and impressions.
- Treat guaranteed results, long lock-ins, and set-and-forget management as red flags.
- Look for a partner who knows your margins and optimizes for profit, not just spend and volume.
