PoolRoute AIThe cost numbers
Cost per click (CPC)
What it is: What you pay each time somebody clicks your ad.
What it does for you: Very little on its own.
Why we are careful with it: A low cost per click feels like winning and often is not. Cheap clicks from people who were never going to call are not cheap, they are wasted. When we switch a campaign from chasing clicks to chasing phone calls, your cost per click usually goes up and your cost per customer goes down. That is a win that looks like a loss on a bad report.
Cost per lead (CPL)
What it is: What you pay for each real lead. A call, a form, a booked job.
What it does for you: This is the number that matters. It is the honest measure of whether an ad channel is working.
How to use it: Compare it across channels. If Google Search is producing leads at $60 and Meta is at $130, you move money. That comparison is on the front of your portal.
Customer acquisition cost (CAC)
What it is: Everything you spent to land one actual paying customer, not just a lead.
What it does for you: Leads are not customers. If one channel produces cheap leads that never close, this is the number that exposes it.
Lifetime value (LTV)
What it is: What a customer is worth over the entire time they stay with you.
What it does for you: It changes what you can afford to pay to get one. A pool account at roughly $2,400 a year, for several years, justifies spending far more to acquire than a one-time job would.
The part specific to your business: that account is also worth roughly the same again when you sell the route, because route sale prices run on monthly recurring revenue. Most operators never count that side.
Return on ad spend (ROAS)
What it is: Revenue divided by ad spend.
What it does for you: Useful in retail where somebody buys once. Less useful for you.
Why: ROAS counts the first month. A pool account pays every month for years. Judging a recurring-revenue business on first-month ROAS makes good marketing look bad.
The activity numbers
Impression
What it is: One instance of your ad being shown.
What it does for you: Almost nothing by itself. Be suspicious of any report that leads with impressions.
Click-through rate (CTR)
What it is: The percentage of people who saw your ad and clicked it.
What it does for you: A diagnostic, not a goal. Low click-through usually means the ad copy or the targeting is off.
Conversion rate
What it is: The percentage of people who landed on your page and then actually did something. Called, filled out a form, booked.
What it does for you: This is where landing pages earn their keep. Doubling your conversion rate is the same as doubling your ad budget, and it costs nothing extra in spend.
Impression share
What it is: The percentage of available searches where your ad actually appeared.
What it does for you: Tells you whether you are missing volume because your budget is capped or because your bids are too low. It is how we know when there is more room in your market.
Frequency
What it is: How many times the average person has seen your ad.
What it does for you: In a tight local area you can hit the same few thousand people over and over. Past a point that stops helping and starts irritating people. We watch it.
Creative fatigue
What it is: When an ad has run long enough that people stop reacting to it.
What it does for you: It shows up as rising cost and falling click-through for no obvious reason. We refresh on a schedule, before it happens rather than after.
The ones we mostly ignore
Not because they are fake, but because they do not tell a pool route operator anything actionable.
| Metric | Why we skip it |
|---|---|
| Impressions | You cannot bank an impression |
| Reach | Same problem |
| Social followers | Nobody hired a pool guy because of a follower count |
| Website sessions | Traffic without calls is a cost, not a result |
| Bounce rate | Wildly misread. Somebody who lands, taps the call button and leaves is a bounce and also a customer |
| Keyword rankings alone | Your rank is different on every street. One number is close to meaningless, which is why we run 49 points instead |
The only number we actually build around
Phone calls. Not a click, not an impression, not a site visit. Someone dialing your number.
That is why the portal opens on calls, and why every tracking decision in the foundation exists to tie each one back to what caused it.
