A lead source is where a lead first heard of you: a referral, a phone call, a web form, or an email you sent them first. You track it with one spreadsheet column and one question asked of every new customer, "How did you first hear about us?"
Marketing software lists a dozen or more sources: organic search, paid ads, social, events, direct mail and so on. A small business does not need that many. Four buckets cover most of it, and if you use them for a month you will be able to answer the one question that matters: where did my last ten customers come from?
Four buckets that cover most small businesses
Referral: someone who knows you or a customer sent them. Outbound: you contacted them first, by email, phone or in person. Inbound call: they phoned you after finding you somewhere, such as Google, a truck, a sign or a directory. Online form: they filled in a form or booked online.
Add an "Other" row as a safety valve, and if it holds more than two of every ten customers, split it. Do not create a bucket for every channel you try. Ten buckets with one customer each tell you nothing.
Ask the question on every call
Put it into the conversation before the price, while the person still remembers: "Before I take your address, how did you first hear about us?" On a web form, add a short optional field with the same words. In an email reply, ask it in your second message.
If the answer is "a friend," follow up: "Who should I thank?" That gives you a name to thank and a record of who sends you work. If the answer is "Google," note whether they called from a map listing or a search result, since those are different. When people cannot remember, write "unsure" and do not guess for them.
One column, written down while it is fresh
Add a column called Source to wherever you keep leads. A spreadsheet is fine; so is a CRM field (see what a customer database should do). Fill it in the moment the lead arrives, not at the end of the month. Record the first way they heard about you, even if they also did something else later. A homeowner who got your name from a neighbor and then looked you up on Google is a referral, not a search lead.
Reading it: ten customers from 55 leads
Tilden Painting is a four-person crew in Madison, Wisconsin. Over a season Mo, the owner, logs 55 leads and wins 10 customers. When he groups them by source, this is what he sees.
| Source | Leads | Customers | Win rate | His time |
|---|---|---|---|---|
| Referral | 6 | 4 | 67% | None to find them |
| Inbound call | 14 | 3 | 21% | Answering the phone |
| Online form | 15 | 2 | 13% | Replying to forms |
| Outbound | 20 | 1 | 5% | 6 hours of emails |
Referrals win two jobs in three, but Mo cannot order more of them. What he can do is ask each past customer once a year for a name, a five-minute call. Calls and forms bring the volume and win about one in five or fewer, so the fix there is reply speed: his form replies go out the next morning, and a painter who answers within the hour tends to beat one who answers tomorrow. Outbound won one customer from six hours of emailing. The question is whether that one job covers the time, and at an $8,000 interior job it does, with a lot to spare.
None of that shows up in the bank balance. Before the column, Mo spent two Saturdays a month on yard signs because they felt like marketing. After it, he moves one of them to emailing the property managers in town, and keeps the other for a phone check on every form lead that sat overnight.
For a fuller look at cost, customer acquisition cost for a small business turns the same table into dollars per customer, and how many leads you need to get one customer shows how to work backward from a revenue goal.
Five ways the numbers mislead you
Counting leads and not customers makes the busiest source look best. Recording the last touch and not the first gives Google credit for what a friend did. Writing "online" without saying which kind hides whether it was a map listing, an ad or a form. Treating ten customers as proof when it is only a hint: one season is a small sample, so look again next quarter. And letting a customer's guess stand: if they say "I think Facebook" and your page has not been posted to in a year, ask a second question.
Phone leads are the usual gap, because nobody writes them down. How to track which phone calls turn into customers covers a call log that fixes it.
Terms you will see next to lead source
Attribution is the practice of giving credit to one or more touches for a sale. A channel is the broad route (email, phone, social), and a source is the specific one (a given referral partner, a specific directory). A lead magnet (see what a lead magnet is) is a thing you offer to create a source. A score (see what lead scoring is) ranks leads after they arrive.
Counting is easier when each lead lands in one place. Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own, so outbound leads and their replies sit together in one pipeline, and an AI worker handles the first touch. Plans that get you customers start at $24.99 a month (Launch), and both Launch and Frontier start with a 7-day free trial, card required.
