The Reporting Gap: What Your Agency Shows You vs What Actually Matters
Your monthly report has 14 pages, 23 charts, and zero insight into whether your Google Ads actually made money. That's not reporting. That's theatre.
The Standard Agency Report
Here's what most agency reports contain: impressions, clicks, CTR, CPC, conversions, conversion rate, ROAS, and spend. Maybe some device breakdowns. Maybe a "top performing campaigns" section. A sentence at the bottom about "continuing to optimise."
None of this tells you whether your Google Ads are profitable. None of it tells you which SKUs are subsidising which. None of it tells you whether scaling spend last month actually improved your P&L or just your dashboard.
The report exists to answer one implicit question: "Is the agency doing a good job?" That's a different question from "Is my Google Ads investment generating commercial return?" The gap between those two questions is where most profit leaks live.
What Gets Reported vs What Matters
| What agencies report | What actually matters |
|---|---|
| ROAS (blended) | Contribution margin after ad spend |
| Total conversions | New customer vs repeat customer split |
| CPC trends | Cost per incremental acquisition |
| Impression share | Impression share on profitable SKUs only |
| Top campaigns by spend | Campaigns ranked by contribution profit |
| Conversion rate | Net conversion rate (after returns) |
| Revenue | Revenue minus returns, minus COGS, minus fulfilment |
The left column describes activity. The right column describes commercial impact. Most agencies report the left. Most CFOs need the right. The gap between the two is why marketing and finance rarely agree on Google Ads performance.
ROAS: The Metric That Flatters Everyone
ROAS is the most commonly reported metric in Google Ads because it almost always looks good. A 4x ROAS means for every £1 spent, £4 came back. That sounds healthy.
But 4x ROAS on a product with 25% gross margin means you spent £1 to generate £1 of gross profit. Before fulfilment. Before payment processing. Before returns. You might be losing money at 4x ROAS and nobody in the room knows it because the report doesn't include margin data.
"ROAS tells you how efficiently your agency spent your money. Contribution margin tells you whether spending it was worth it. They're not the same question."
What a Commercially Useful Report Looks Like
A report that actually informs decisions covers five areas:
1. Contribution margin after ad spend
Not ROAS. The actual profit generated after subtracting COGS, fulfilment, payment processing, and ad spend. This is the only number that connects your Google Ads to your bank account.
2. SKU-level profitability
Which products are driving profitable conversions and which are eating budget? A blended ROAS across 500 SKUs hides the fact that 30 products are subsidising the other 470.
3. New vs repeat customer economics
If 40% of your "conversions" are repeat buyers who would have purchased anyway, your true acquisition cost is nearly double what the report shows. This distinction changes every budget decision.
4. Cash recovery period
How long until the cash you spent on ads comes back? For brands with 30-60 day payment terms, a fast-growing Google Ads account can create a cash flow crisis even when ROAS looks healthy.
5. Search term relevance
Not just what search terms triggered ads, but which search terms drove profitable orders. This is the single most actionable diagnostic and it's missing from most reports entirely.
Why We Replaced Monthly Reports with Weekly Looms
A 14-page PDF that arrives on the 5th of the month telling you what happened last month is an autopsy, not a management tool. By the time you've read it, two more weeks have passed.
We switched to weekly Loom videos. 5-8 minutes. Screen-shared dashboards. Plain language. "Here's what happened this week. Here's what we're changing. Here's the commercial impact." No decks. No formatting. No theatre.
The result: problems get caught in days, not months. Budget reallocation happens weekly, not quarterly. And clients actually watch them - because a 6-minute video is easier than parsing 14 pages of charts they didn't ask for.
Five Questions to Ask Your Agency This Week
- 1.What was our contribution margin after ad spend last month - not ROAS, the actual cash profit?
- 2.Which 10 SKUs consumed the most budget and what was the contribution margin on each?
- 3.What percentage of our conversions came from repeat customers vs new customers?
- 4.What are the top 20 search terms by spend and how many of them are relevant?
- 5.If we increased budget by 20% next month, where exactly would the extra spend go and what return would you expect?
If your agency can't answer these quickly and clearly, the gap between what they report and what you need is wider than you think.
