Most of your leads come from one thing. Find out which.

What the split usually looks like

In most local service accounts we take over, the concentration is more extreme than eighty and twenty. One channel produces the majority of booked work, and inside that channel three to six search terms produce most of the leads. Everything else is a long tail of single leads that feels like activity and reads like progress on a monthly report.

The useful version of this rule is not a ratio, it is a habit. Before adding anything new, find out what is already carrying the business and make sure you have not been quietly starving it while your attention was somewhere else.

Where to look for the real 20 percent

Three places, in this order.

• The search terms report in Google Ads, sorted by conversions rather than clicks. Search terms, not keywords. Keywords are what you bought. Search terms are what people typed.

• The performance section of your Google Business Profile, which separates searches for your business name from searches for what you do, and shows which produced calls and direction requests.

• Whoever answers your phone. Have them write down, for one month, the first sentence out of each caller's mouth. It is the cheapest research available and it regularly contradicts the dashboard.

Then match all of it against jobs that closed, not leads that arrived. A term producing eight cheap leads that never book is not your twenty percent, however good it looks in a conversion column.

Three things that look like the 20 percent and are not

Branded search. People typing your company name are already sold, and something else sold them. Counting those conversions as a win for whichever channel caught them at the end credits the doorman with the dinner.

The homepage. It gets more traffic than anything else on almost every site, which makes it look like your best performer. Most of that traffic was coming anyway.

The cheapest cost per lead. Cheap leads are usually early-stage. In home services an expensive emergency call often books at twice the rate of a cheap research click, so the campaign with the worst cost per lead can be the one paying the bills. Cutting it is the most common self-inflicted wound we see.

So what should you actually cut?

Cut carefully, because part of the eighty percent is scaffolding. Reviews never appear as a lead source on any report, and they decide whether the leads you already paid for pick up when you call back. Referrals do not show in analytics at all. A social page with almost no engagement is still the second thing somebody checks after a recommendation.

The things genuinely worth cutting are specific and boring: a display campaign nobody remembers switching on, four directory listings billed annually since 2019, a broad match keyword spending a quarter of the budget on searches for a trade you do not practice, a second blog last updated by an employee who left. That is real money and nobody will miss it.

Why the rule breaks at small volume

If you get fifteen leads a month, there is no split that survives contact with next month. Three leads landing differently rearranges the whole ranking. At that volume, comparing channels on a monthly report means reading noise and then acting on it.

Use a longer window. Ninety days at minimum, a full year where you have it, and compare the same season against the same season. An HVAC business in February and the same business in July are two different companies serving two different customers.

How to move money without gambling

Shift budget toward the winner in increments and watch cost per booked job rather than cost per lead. Doubling spend on your best campaign rarely doubles the leads, because the cheapest available demand gets bought first and what is left costs more. Expect the price to climb as you scale, and decide in advance what you are still willing to pay.

Then leave it alone long enough to read the result. Most accounts we inherit have been adjusted every week for a year, which makes it impossible to attribute any outcome to any decision. A change needs a few quiet weeks to be worth anything.

The honest limit

Concentration describes the past. It tells you what worked under conditions that existed, and those conditions move: a competitor doubles their budget, a term gets expensive, a platform changes how a campaign type serves ads. Recheck the split a few times a year and treat any finding older than two seasons as a guess.

It is also worth saying what this exercise finds, which is efficiency rather than growth. Concentrating on what already works makes the same business more profitable. It will not find you a new kind of customer, and at some point the winning channel runs out of room. Keep something running elsewhere anyway. A business in New Jersey with one lead source and no second option is not efficient, it is exposed.
