Not all digital marketing agencies deliver equal results, and the difference often isn’t obvious until you’re six months into a contract with little to show for it.
The problem is that agencies are usually evaluated on the pitch — the deck, the case studies, the price. All three are marketing materials produced by people who market for a living. They tell you how well the agency sells, not how well it delivers.
Here’s a more reliable way to assess an agency before you sign, and how to keep assessing once you have.
Start With the Reports
Ask every agency you’re considering: can I see a sample monthly report for a current client, with the client details removed?
This single request separates agencies faster than anything else, because a report is the only artefact that reveals what the agency actually optimises for.
| A strong report contains | A weak report contains |
|---|---|
| Cost per conversion | Impressions |
| Return on ad spend or cost per lead | Click-through rate |
| Revenue or enquiry volume | Reach and engagement |
| Month-on-month comparison | A single month in isolation |
| A specific plan for next month | A summary of last month’s activity |
An agency that reports only on the right-hand column isn’t necessarily doing poor work. But it has no way of telling whether the work produced anything, and neither will you.
The Questions That Reveal Quality
Who will manage my account day to day? You should meet that person before signing, not just the business development team. Ask how many accounts they handle.
Can I see results from a similar business? Ask for conversion data, not portfolio screenshots. A design gallery tells you the agency can build things, not that the things worked.
What happens if results don’t meet expectations? A confident agency has a clear answer involving diagnosis and a revised plan. Evasion, or an immediate suggestion to increase budget, is a warning sign.
Will my ad accounts be in my name? Non-negotiable. If the agency holds the accounts, you lose every piece of data and learning the day you leave.
Is your team in-house or outsourced? Neither is inherently wrong, but you’re entitled to know where the work happens and who has access to your accounts.
Contract Red Flags
Twelve-month lock-ins with heavy exit penalties. No performance measures defined anywhere in the agreement. Setup fees charged on top of management fees with no itemised breakdown of what the setup includes.
One more worth watching for: agreements where the agency retains ownership of creative assets, landing pages or tracking configurations built during the engagement. You paid for them; they should be yours.
Evaluating an Agency You’ve Already Hired
Most of this advice assumes you’re choosing. If you’re already six months in and unsure, the assessment is different.
Ask for three things: written confirmation that accounts are in your name, a report showing cost per enquiry over the last six months, and the plan for the next quarter. How readily those arrive tells you most of what you need to know.
Then check one number yourself. Compare enquiries recorded in the agency’s reporting against enquiries that actually reached your inbox or phone. A meaningful gap means the tracking is wrong, and every decision made from that data has been guesswork.
Where to Start
This week: Calculate your current cost per enquiry. Every conversation with an agency is more productive once you know this number.
Before signing: Request sample reports from at least two agencies and compare them side by side. Meet the person who’ll do the work.
First 90 days: Confirm account ownership in writing, verify tracking against real enquiries, and agree what success looks like in numbers rather than adjectives.
Frequently Asked Questions
How long should I give a new agency before judging performance?
Search advertising usually shows direction within four to six weeks and structural improvement by month three. SEO takes three to six months. Judging either earlier tends to produce panic decisions.
Should I choose the agency with the lowest fee?
Management fees are a small part of the total cost. An agency charging $500 more per month but improving cost per lead by 20% is far cheaper in practice. Compare on results per dollar of total spend.
Is it a problem if the agency also works with my competitors?
Not necessarily — category experience is genuinely useful. Ask how they handle conflicts, particularly around bidding on the same keywords for two clients.
What if the agency won’t provide a sample report?
Confidentiality is a fair reason to redact client details, not to decline entirely. An outright refusal usually means the reports wouldn’t survive comparison.
Can a small business afford a good agency?
Often yes, though the structure may differ — a setup-only engagement or a smaller scope retainer rather than full management. A good agency will tell you when your budget doesn’t yet justify their fee.
