The five numbers that tell you if your website makes money

Visits, conversion rate, cost per lead, lead-to-customer rate and cost per customer: what they mean and how to read them together.
Most small business owners judge their website by how it looks. Is the logo right, are the colours nice, does it feel modern? Those things matter, but they don't answer the question that pays the bills: what does this website bring in?
Five numbers answer that question. You don't need complicated software to track them, and once you know them, you will know exactly where to spend your next rupee of marketing, and where to stop. This article explains each number in plain words, shows how they connect, and ends with a simple monthly routine. All figures used here are examples to show the arithmetic, not results from a real business.
1. Visits: how many people arrive
Visits are the number of times people opened your website in a month. Most website builders and Google Analytics show this. On its own, the number says surprisingly little. A thousand visits from people in another state, looking for something you don't sell, are worth less than fifty from your own neighbourhood looking for exactly your service.
So when you look at visits, ask two follow-up questions: where did they come from (Google search, Google Maps, Facebook, Instagram, an ad, a WhatsApp link) and which page did they land on? A rise in visits from local searches to your service pages is good news. A rise in visits to your "About us" page from a random social post is nice, but rarely changes your sales.
If your visits are low, the fix is to be found: a complete Google Business Profile, pages that match what people search, and possibly ads. Our 30-day local SEO checklist covers the first steps.
2. Conversion rate: how many visitors act
Of the people who visit, how many do something useful? For a local business, "useful" usually means filling in an enquiry form, tapping a WhatsApp button, or tapping a call button. Each of those is a lead: a real person who has raised their hand.
Conversion rate = leads ÷ visits. If 400 people visit in a month and 12 enquire, your conversion rate is 3%.
This is the number a good website improves most, and the one most owners never measure. Two websites with the same visitors can produce very different results. Imagine two salons, each with 400 visitors a month. One has a slow site with the phone number hidden at the bottom; it converts 1%, so 4 enquiries. The other loads fast, shows "Book on WhatsApp" on the first screen and lists prices clearly; it converts 4%, so 16 enquiries. Same visitors, four times the enquiries.
What raises conversion rate? A headline that matches what the visitor searched for, one clear benefit, a visible action button, proof such as reviews and real photos, and speed. We explain these in detail in our guide to what belongs above the fold. If you want to see a page built this way for your own business, start with a free first draft.
3. Cost per lead: what each enquiry costs you
If you pay for ads, divide what you spent by the leads they brought. Cost per lead = ad spend ÷ leads. Spending ₹6,000 on ads in a month to get 20 enquiries means ₹300 per lead.
Cost per lead is useful because it lets you compare channels fairly. Perhaps Google search ads bring leads at ₹300 each and Facebook ads at ₹180. That doesn't automatically mean Facebook is better, because the quality of the leads may differ. That is what the next number reveals.
If you don't run ads, you can still think about cost per lead: what do you pay each month for your website, your listing and any marketing help, divided by the leads they bring? Even "free" channels have a cost in time.
4. Lead-to-customer rate: how many enquiries buy
Not every enquiry becomes a customer. Of 20 enquiries, perhaps 5 buy. That is a 25% close rate. This number lives mostly with you, not the website: how quickly you reply, how clearly you quote, how you follow up, and whether your prices fit what the enquiry expected.
Close rate is where many businesses lose money without realising. A lead that waits a day for a reply has often already booked someone else. Simple habits make a big difference: reply within the first hour during working hours, use a short template for common questions, and follow up once if you hear nothing. Keeping every enquiry in one place, rather than scattered across WhatsApp chats and email, helps too. That's what the Lead Inbox in our growth plans is for.
Comparing close rates by source is revealing. If Google search leads close at 40% and Facebook leads at 10%, the Facebook leads were cheaper but less ready to buy.
5. Cost per customer: the number that decides everything
Now bring it together. Cost per customer = cost per lead ÷ close rate. At ₹300 per lead and a 25% close rate, each new customer cost ₹1,200 in ads. In the channel comparison above, Google leads at ₹300 with a 40% close rate give ₹750 per customer, while Facebook leads at ₹180 with a 10% close rate give ₹1,800 per customer. The "cheaper" leads were actually more than twice as expensive.
Finally, compare cost per customer with what a customer is worth to you. If a typical customer brings ₹3,000 of profit over the time they stay with you, paying ₹1,200 to win them is a good trade. If they bring ₹800, it is not. Our article on working out your ad budget from one customer walks through this in detail, and the pays-for-itself calculator lets you test your own numbers in seconds.
Reading the five numbers together
The power of these numbers is that each one points to a different fix:
- Few visits → you need to be found: Google profile, local SEO, content, perhaps ads.
- Plenty of visits, few leads → the website is the problem: speed, clarity, the action button, trust.
- Plenty of leads, few customers → the follow-up is the problem: response time, pricing, how you talk to enquiries.
- Good customers but too costly → shift spending towards the channels with the lowest cost per customer.
Without the numbers, owners tend to fix the wrong thing. A business with a follow-up problem redesigns its website; a business with a website problem spends more on ads. Both spend money without moving the result.
A simple monthly routine
- On the first of each month, write down last month's visits, leads (forms, WhatsApp taps, call taps), ad spend and new customers.
- Calculate conversion rate, cost per lead, close rate and cost per customer. A notebook or a simple spreadsheet is enough.
- Pick the weakest number and make one change to improve it.
- Next month, check whether that number moved.
Do this for three months and you will understand your business online better than most of your competitors.
