Why it matters

Conversion rate compresses funnel efficiency into a single metric, making it easier to judge landing pages, sales motions, and channel quality.

When to use

  • Evaluating campaign landing page performance
  • Reviewing lead funnel quality
  • Estimating order volume from traffic projections

Inputs & Outputs

Inputs

  • Visitors or leads are the total opportunities that entered the funnel.
  • Conversions are the completed purchases, signups, or target actions.

Outputs

  • Conversion rate shows the share of opportunities that converted.
  • Non-converting count shows the remaining volume that dropped off.

Conversion rate formula

Divide conversions by the total number of opportunities and multiply by 100 to express the result as a percentage.

Conversion rate = (conversions / visitors) x 100

Worked example

1

Landing page review

A campaign sent 18,000 visitors and generated 540 purchases.

Inputs

  • Visitors: 18,000
  • Conversions: 540

Steps

  • Rate = 540 / 18,000 = 3%

Result

  • The landing page converted at 3%.

Edge cases & caveats

  • Conversion rate depends heavily on traffic quality and funnel definition.
  • Do not compare rates across channels unless the conversion event is identical.

Frequently Asked Questions

Can conversion rate exceed 100%?

No. If it does, the inputs are not aligned. A conversion count higher than the opportunity count usually means double-counting or a mismatched time window.

Should I use sessions or users?

Use the denominator that matches your reporting model. Just keep it consistent when comparing periods.
