How to choose marketing channels by what a customer is worth

Most channel debates start in the wrong place. Owners ask whether they should “do Google Ads” or “try TikTok” before they know what a new customer is worth, how long that customer takes to decide, or how many more customers the business can actually serve. Those three answers narrow the choice faster than any trend report.

1. Work out what a customer is worth

Start with gross profit, not revenue. A $6,000 implant case and a $180 hygiene visit may both start with a phone call, but they justify very different acquisition costs. Where customers come back — a heating maintenance plan, a retail customer who reorders — estimate value over a realistic period, such as the first year, rather than an optimistic lifetime.

From that, set a ceiling: the most you can spend to win one customer and still be comfortable. Our growth calculator turns that into a break-even cost per lead using your own close rate.

2. Match the channel to how people decide

• Urgent needs (a burst pipe, a toothache) are searched for and solved within hours. Search ads, local SEO and fast phone answering matter most.
• Considered purchases (implants, renovations, legal matters) take weeks. People compare, read and come back. Search still matters, but content, reviews, remarketing and patient follow-up carry more weight.
• Discovery purchases (a new boutique, a product people didn’t know existed) need demand created first. Social and video advertising earn attention; search captures it later.

3. Respect capacity

More leads only help if someone can answer them. A business that can take five more jobs a week should optimise for quality and cost, not volume. If capacity is the constraint, follow-up, booking and pricing often produce more growth than another channel.

4. Build in a sensible order

1. Make sure enquiries are tracked from source to booking — otherwise every later decision is a guess.
2. Capture the demand that already exists: search ads and a complete Google Business Profile.
3. Fix the leaks after the click: page speed, forms, response time.
4. Then expand into channels that create demand, and judge them on booked work, not clicks.

A worked example

A home-services company with high-value replacements and urgent repairs might put most of its budget into search and local visibility, add call-focused ads after hours, and use remarketing for the slower replacement decisions. Social video becomes worth testing once tracking shows which jobs come from which source.

If you’d like a second opinion on your own mix, book a call — we’ll start with the numbers above, not with a channel.
