CVR: definition, calculation and conversion rate optimisation
Updated on February 22, 2026
Quick definition
CVR (Conversion Rate) is the conversion rate that measures the proportion of visitors to a site or page who complete a desired action — purchase, sign-up, download. CVR is one of the most critical KPIs in digital marketing because it directly translates the effectiveness of a page or sales funnel.
How it works
Formula
CVR = (Number of conversions / Number of visitors or sessions) × 100
Example: 150 purchases for 5,000 visitors on a landing page give a CVR of 3%.
CVR varies considerably by conversion type and sector:
- E-commerce purchase: on average 1 to 4%
- Newsletter sign-up: 10 to 30% with a well-optimised form
- SaaS demo request: 2 to 8% depending on traffic quality
It is essential to distinguish macro-CVR (final conversion, e.g. purchase) from micro-CVR (intermediate steps, e.g. add to cart). Analysing micro-conversions lets you pinpoint precisely where users drop off in the conversion funnel.
CVR must always be analysed in conjunction with traffic quality: highly targeted traffic (long-tail SEO, segmented email) structurally converts better than broad display traffic.
Why it matters
CVR sits at the heart of the profitability of a website or marketing campaign. Doubling your conversion rate doubles your revenue without raising your acquisition budget.
A rise in CVR mechanically reduces CPA and CAC, improving the overall profitability of your digital strategy.
- CVR by traffic source → identifies the highest-converting channels
- CVR by device → reveals mobile experience problems
- CVR by audience segment → prioritises optimisation efforts

Frequently asked questions
What is a good conversion rate for an e-commerce site?
The average e-commerce conversion rate sits between 1% and 4% depending on sector. Fashion sites convert on average at 1.5–2%, while specialised niches or sites with strong branded traffic can exceed 5%. The key is to compare your CVR to your sector's average and analyse its evolution over time rather than chase an absolute number.
What is the difference between CVR and CTR?
CTR measures the click-through rate on a link or ad (from view to click), while CVR measures the conversion rate on a page or in a funnel (from visitor to action completed). CTR sits at the top of the funnel, CVR further down. The two metrics are complementary for optimising the entire user journey.
How do I calculate the conversion rate of a contact form?
Divide the number of forms submitted by the number of visitors who saw the page containing the form, then multiply by 100. For example, if 800 visitors see your contact page and 40 fill out the form, your CVR is 5%. Be sure to exclude spam submissions to obtain a representative rate.
