Conversion Rate

Conversion rate is the percentage of visitors, clicks or leads that complete a desired action. A conversion can be a submitted form, a booked call, a purchase or a signed contract.

Formula

Conversion rate = number of conversions ÷ number of visitors (or clicks) × 100%

Be clear about what you count: visitors, sessions or clicks in the denominator – and which action in the numerator.

Example

A landing page gets 4,000 visitors from Google Ads per month. 120 of them fill out the inquiry form.

Conversion rate = 120 ÷ 4,000 × 100% = 3%

If a shorter form lifts the conversion rate to 4%, you get 160 instead of 120 inquiries for the same budget – and your cost per lead drops by a quarter.

Conversion rates along the funnel

In lead generation, there is not one conversion rate but several in a row:

• Visitor → lead: How well does the landing page convert?
• Lead → meeting: How good are the leads, and how fast does sales follow up?
• Meeting → deal: How well does your team sell?

A campaign can shine at the first stage and collapse at the later ones. Only when you see every stage per campaign do you know where to act.

LeadMetrics attributes leads to their campaign and ad and connects them with deals and deal stages from your CRM. With the funnel analysis widget in dashboards, you see how many leads from each source make it all the way to a deal.

Conversion rate in the ad platforms

Meta and Google Ads calculate conversion rate based on the conversions they capture themselves. When events are lost to ad blockers or missing consent, the rate looks worse than it is. Sending conversions server-side closes part of that gap.

Common mistakes

• Comparing apples to oranges: A newsletter signup and a purchase have completely different rates.
• Too little data: With 50 visitors, a one-point difference is just noise.
• Optimizing only the first stage: More leads are worthless if none of them buy.
