Conversion Rate
Conversion rate is the percentage of users who take a defined action out of those who had the opportunity to take it. The defined action is typically a sign-up, purchase, demo request, or upgrade, and the metric is used as the core unit of funnel performance measurement. It is calculated as actions taken divided by opportunities, expressed as a percentage, and it is meaningful only when the action, the denominator, and the time window are all defined precisely.
Benchmarks vary widely by stage, industry, and traffic source. E-commerce site visit-to-purchase typically runs 2 to 3 percent across all traffic, with Shopify's published median around 1.4 percent. B2B SaaS landing page visit-to-trial-signup typically runs 2 to 5 percent. Self-serve SaaS trial-to-paid conversion typically runs 15 to 25 percent depending on whether the trial is free or requires a credit card up front. Paid-search landing pages convert higher than cold display traffic because the intent is higher; comparing the two without segmenting by source is one of the fastest ways to mislead yourself. The single most common reason founders misread their conversion rate is denominator drift: a stricter definition of "qualified visitor" produces a higher conversion rate but makes the metric incomparable over time and across reports.
Ryan's Take
A conversion rate without context is a vanity number. "We have a 12 percent conversion rate" tells me almost nothing until I know what is converting to what, across which traffic source, over what time window, and against what benchmark. The work in measuring conversion is in being honest about your denominator. Founders quietly redefine the denominator when the number looks bad, then celebrate the new number. That is just lying to yourself in a spreadsheet. Lock the definition once, write it down, and only change it deliberately with a footnote.
What founders get wrong: Optimizing the conversion rate of a stage that is not the bottleneck. Pushing a landing page from 3 percent to 4 percent feels productive, but if the real problem is that 95 percent of new signups never come back in week 2, the funnel work that matters is at activation, not acquisition. Always find the binding constraint before you start optimizing.

FAQ
What is a conversion rate?
The percentage of users who take a defined action out of the total users who had the opportunity to take it. Calculated as actions taken divided by opportunities, expressed as a percentage. The defined action can be a signup, purchase, demo request, or any goal you specify.
What is a good conversion rate?
It depends on stage and industry. E-commerce visit-to-purchase typically runs 2 to 3 percent. B2B SaaS landing page visit-to-trial-signup runs 2 to 5 percent. Self-serve SaaS trial-to-paid conversion runs 15 to 25 percent. Always compare against a peer benchmark, not an absolute number.
How do I calculate conversion rate?
Divide the number of users who completed the action by the number who had the opportunity, then multiply by 100. For example, 50 signups from 2,000 visitors is a 2.5 percent conversion rate. Define your denominator clearly and keep it consistent.
