Why the common number misleads
Platforms report “cost per result” or “cost per message”, usually spend divided by form submissions — including wrong numbers, duplicates and idle curiosity.
Then someone says “our leads cost 12 riyals”. That describes the cost of a form, not of a lead that can buy.
First: what is a qualified lead?
Before any calculation, define qualification. The definition is what gives the number meaning:
| Element | Qualified | Unqualified |
|---|---|---|
| Budget | Within the project range | Far below, or “just asking” |
| Location | Searching the project area | Outside the area |
| Timing | Buying within 3–6 months | Undefined future |
| Seriousness | Asked about payment and delivery | Asked for photos only |
Without this definition, every number flatters reality.
The correct equation
Cost per qualified lead = total ad spend ÷ number of qualified leads.
Example: SAR 9,000 spent, 120 enquiries, 45 qualified. Cost per form is SAR 75; cost per qualified lead is SAR 200. Both are correct, but only one informs the decision.
What counts and what does not
Include: ad spend, campaign management fees if tied to the campaign, and production made specifically for it.
Exclude: the full website cost (a long-term asset) and fixed salaries — unless you are calculating “full acquisition cost”, which is a different metric for annual comparison.
Four costs, not one
| Metric | What it measures | When to use it |
|---|---|---|
| Cost per form | Ad efficiency | Comparing creatives |
| Cost per qualified lead | Targeting quality | Budget decisions |
| Cost per viewing | Market seriousness | Assessing the sales team |
| Cost per deal | Profitability | Scaling decisions |
Most brokerages measure only the first, then wonder why budget rises without sales following.
How do you know your number is good?
There is no universal benchmark: cost varies by city, competition and price. The right method is to compare it with deal value.
At SAR 200 per qualified lead and a deal margin in the tens of thousands, you are fine. At a SAR 3,000 margin, the number is high even if it looks small.
Five reasons cost rises
- Targeting a wider audience than needed (the whole city instead of the area).
- Creative that ignores price and location, attracting curiosity not intent.
- No qualification: the form asks nothing.
- Slow response, letting the lead cool and forcing a second acquisition.
- Audience fatigue: the same creative for over a month.
How to lower it without lowering quality
Start with qualification: two questions in the form (budget and area) reduce form count and raise quality — cost per form may rise while cost per qualified lead falls.
Then fix response: reducing time to first reply raises the share reaching a viewing with no change to the ad.
In short
Cost is not one number but four: form, qualified lead, viewing and deal. A report showing one of them cannot drive a decision.
If you track a single metric, make it cost per qualified lead against deal margin.
