A Sky Designers performance case study — five months of Meta advertising, April to August 2026
Across five months, LKR 557,742 in Meta ad spend produced 11,372 WhatsApp conversations and 1,673 confirmed orders worth LKR 3,329,270 — a blended return of 5.97x, at an average acquisition cost of LKR 333 per order.
Every single month returned at least four times its ad spend. But the most instructive month wasn't the best one. It was August — the month with the highest budget and the second-worst return.
The Five-Month Picture
| Metric | Result |
|---|---|
| Total ad spend | LKR 557,742 |
| Conversations started | 11,372 |
| Confirmed orders | 1,673 |
| Order value | LKR 3,329,270 |
| Return on ad spend | 5.97x |
| Cost per order | LKR 333 |
| Cost per conversation | LKR 49 |
| Conversation → order | 14.7% |
The selling price stayed identical in all five months, which makes this a genuinely clean comparison. Nothing on the revenue side distorts the month-to-month picture — return on ad spend moves entirely with cost per order.
Month by Month
| Month | Spend (LKR) | Orders | ROAS | Cost / order |
|---|---|---|---|---|
| April | 111,184 | 383 | 6.86x | LKR 290 |
| May | 104,564 | 223 | 4.24x | LKR 469 |
| June | 93,670 | 314 | 6.67x | LKR 298 |
| July | 96,582 | 372 | 7.66x | LKR 260 |
| August | 151,742 | 381 | 5.00x | LKR 398 |
July is the benchmark: the lowest cost per order of the period, at a spend level the account handles comfortably.
The August Problem
August spent LKR 55,160 more than July — a 57% increase. It generated 3,417 conversations, the most of any month in the period.
It produced nine more orders.
826 additional conversations. Nine additional orders. On the incremental rupee, August returned LKR 0.32.
What went wrong wasn't the media. August had the cheapest impressions of the entire period — CPM fell to LKR 238, the lowest of the five months. Cost per conversation was LKR 44, comfortably below the LKR 49 average. Frequency sat at 1.37, nowhere near fatigue.
The media buying was the best it had been all period. The conversation-to-order rate collapsed to 11.2%, the worst of the five months.
The Arithmetic That Matters
At July's close rate of 14.4%, August's 3,417 conversations would have produced roughly 492 orders instead of 381 — about LKR 979,000 in order value from exactly the same spend, at a return of 6.45x.
That's roughly 110 additional orders per month available at zero additional ad spend.
This is the most important finding in five months of data. The account does not have a media problem. It has a response problem. And no amount of extra budget fixes a step that happens after the ad has already done its job.
Media Got Cheaper Every Month
The underlying delivery trend was strong throughout:
- CPM fell 37% — LKR 377 in April to LKR 238 in August. Buying the same 1,000 impressions became a third cheaper across the period.
- Cost per conversation fell 17% — LKR 53 to LKR 44, with July's LKR 37 the low point.
- Frequency fell from 2.34 to 1.37 — audiences aren't being over-exposed, and there's headroom to spend more without paying a fatigue premium.
This matters because it rules out the obvious explanation. August didn't underperform because the account was saturated or because media got expensive. Both moved in the right direction.
Strong Creative Doesn't Close the Sale
A creative change in April doubled hook rate from 21.1% to 42.6%, and it has stayed above 40% ever since. Four in ten people who see the ad start watching it. Hold rate has been stable in a narrow 33.6–35.8% band — a third of everyone who starts the video watches it through.
And yet May, which had the second-highest hook rate of the period, delivered the weakest ROAS at 4.24x.
The lesson is uncomfortable but useful: strong creative brings the conversation. The reply that follows decides the order. Attention metrics tell you the ad is working. They tell you nothing about whether the business is converting what the ad delivers.
What Five Months Establish
- A proven return. 5.97x blended, with no month below 4x. The channel works for this product at this price.
- A benchmark to beat. July's LKR 260 per order at 7.66x is the standard for the months ahead, not a one-off.
- Room to scale on the media side. CPM down 37%, frequency down to 1.37 — the account can absorb more budget without fatigue.
- The next gain isn't in Ads Manager. Recovering July's close rate at August's volume is worth roughly 110 extra orders a month at no additional ad spend.
The Takeaway
Scaling a Meta account is usually framed as a media question: can you spend more without costs rising? Here, the answer was yes — impressions got cheaper the whole way up.
The ceiling was somewhere else entirely. Once the ads were delivering 3,400 conversations a month, the constraint stopped being how many people you could reach and became how many of them got a good reply.
Before you increase a budget, check whether the last step in your funnel can handle the volume the first step is already producing.
