Lead Source Mix

Distribution of total leads by acquisition channel (organic, paid, referral, events, direct), identifying channel dependency

What is Lead Source Mix?

Lead source mix is the share of leads that come from each channel. It shows how dependent the business is on particular sources.

A balanced mix reduces risk, since relying on one channel leaves the business exposed if that channel changes or becomes more expensive.

(Leads from each channel / Total leads) × 100 per channel

How to calculate it

For each channel, divide the leads from that channel by total leads, and multiply by 100.

For example, if 1,000 leads came in and 400 were from search, 250 from email, 200 from events and 150 from referrals, the mix is 40%, 25%, 20% and 15%.

Track how the mix changes over time and compare each channel's share with its share of conversions and revenue.

Where it is used

  • Managing risk

    Spot over-reliance on one source.

  • Guiding investment

    Decide whether to develop underused channels.

  • Understanding the funnel

    See how each source contributes.

How to improve it

Tips and common mistakes

  • The source that gives the most leads may not give the most revenue. Check quality.
  • Keep source categories stable, or trends will be unreliable.
  • Investigate leads with an unknown source, which can hide the true picture.
