Landing Page Conversion Rate Calculator

Conversion Rate on Landing pages

A landing page's conversion rate is conversions (form fills, sign-ups, demo requests) ÷ unique visitors to the page. Use unique visitors, not pageviews — reloads and back-button visits inflate the denominator. Segment by traffic source before judging the page: the same page converts differently for paid search, paid social and email traffic because visitor intent differs.

Comparing two pages — or two versions of one — is where most conversion-rate decisions go wrong. A 5.0% vs 4.4% difference on 3,800 visitors each is inside normal random variation. Compute the rate here, then check whether the gap is significant with the A/B Test Significance Calculator before declaring a winner or rewriting the page.

Formula

Conversion rate (%) = Conversions ÷ Visitors × 100
Visitors per conversion = Visitors ÷ Conversions

How to read Conversion Rate

Conversion rate is the share of visits, sessions or clicks that end in the action you care about — a purchase, a lead, a sign-up. It is the multiplier that turns traffic into results, which is why a small change in conversion rate moves revenue as much as a large change in traffic.

Be explicit about the denominator. Conversions ÷ users, ÷ sessions and ÷ ad clicks give three different rates for the same campaign. Pick one definition per report and keep it, or comparisons between periods and channels become meaningless.

Frequently asked questions

What is a good landing page conversion rate?

Lead-generation pages for paid traffic commonly convert in the low-to-mid single digits, and well-targeted pages with a strong offer run well above that. The traffic source matters as much as the page: email and retargeting visitors convert at several times the rate of cold paid social.

Should I count every form submission?

Count qualified submissions if you can — spam, duplicates and test entries inflate the rate. If your form tool tags them, exclude them; if not, track them separately so the trend is not distorted by a bot burst.

What is a good conversion rate?

It varies by industry, traffic source, device and the action being measured. E-commerce purchase rates are commonly low single digits; lead forms on paid search can be far higher. Your own rate by channel, tracked over time, is the only benchmark that leads to good decisions.

Sessions or users — which should I use?

Use sessions when judging landing pages and campaigns (one visit, one chance to convert). Use users when judging the overall funnel over a longer window, since one person may visit several times before converting.

How many visitors do I need to detect an improvement?

That is a sample-size question, not a conversion-rate question. At a 2% baseline, detecting a relative 10% lift with 95% confidence needs tens of thousands of visitors per variant. A sample size calculator gives the exact figure for your numbers.
