How to know which marketing brings you customers

If you don't know which marketing brings in customers, you can't tell what's worth paying for. Here's what lead source tracking shows you, and why most businesses get it wrong.

Why "How did you hear about us?" isn't enough

Asking customers is a start, but memories are fuzzy. Someone who saw your ad, then searched your name and filled in your form will often just say "Google". Decisions based on that can send your budget to the wrong place.

What you should be able to see

  • Where each lead first came from: Google, Maps, ads, social or an AI assistant
  • Which pages and services bring in leads
  • Which leads became customers, and what they were worth
  • Your real cost per customer for each paid channel

Leads aren't the finish line

One channel might send lots of small jobs while another sends fewer, bigger ones. Counting leads alone can make the wrong channel look like the winner. The businesses that grow fastest track all the way to revenue.

Why most businesses don't have this

  • Tracking is set up once and quietly breaks
  • Leads live in inboxes, texts and spreadsheets instead of one place
  • Nobody records which leads were won and for how much
  • Reports from different tools don't agree

How we help

MET Signal traces every website lead back to where it came from, keeps them in a simple CRM, and credits each won job's revenue to the channel that found the customer. You can mark jobs won by hand, import them, or sync them from your job software.

Questions

Do I need a CRM to track lead sources?+

It helps a lot. A simple CRM lets you move leads from new to quoted to won, which is how marketing gets connected to revenue. MET Signal includes one.

Can I track phone calls?+

MET Signal doesn't track calls. Your team can log calls on each lead in one tap so everyone sees where things stand.

Is lead source tracking legal?+

Yes, when done transparently. Disclose it in your privacy policy and follow the privacy rules that apply to your business.
