The Quick Answer
Conversion rate = (Conversions ÷ Total Visitors) × 100
If 2,000 people visited your page and 60 completed a purchase, your conversion rate is (60 ÷ 2,000) × 100 = 3.0%.
What Is Conversion Rate?
Conversion rate is the percentage of visitors who complete a desired action on your website, landing page, or campaign. That action — the "conversion" — can be anything you define as a goal:
- A purchase
- A free-trial signup
- A form submission
- An email subscription
- An app download
The metric tells you how effectively your page turns visitors into customers, leads, or subscribers. A higher conversion rate means more results from the same amount of traffic.
The Formula
Conversion Rate (%) = (Number of Conversions ÷ Total Visitors) × 100
Total visitors can mean sessions (visits) or unique visitors, depending on how your analytics tool counts. Sessions is the most common denominator, because one person often visits multiple times before converting.
Worked Examples
E-commerce Store
An online store had 15,000 sessions in January and recorded 375 completed purchases.
- 375 ÷ 15,000 = 0.025
- 0.025 × 100 = 2.5%
- That means roughly 1 in every 40 visitors bought something
At 2.5%, this store is right at the e-commerce average.
SaaS Free Trial Page
A software product's pricing page received 4,000 visits last month. 160 visitors started a free trial.
- 160 ÷ 4,000 = 0.04
- 0.04 × 100 = 4.0%
- Roughly 1 in 25 visitors signed up
A 4.0% trial signup rate is within the typical B2B SaaS range of 3–5%.
Paid Ad Landing Page
A Google Ads campaign sent 2,500 clicks to a landing page. 225 visitors submitted the lead form.
- 225 ÷ 2,500 = 0.09
- 0.09 × 100 = 9.0%
- About 1 in 11 visitors converted
A 9.0% landing page conversion rate is strong — above the 2–5% average for paid traffic.
What Is a Good Conversion Rate?
There is no single "good" number. Benchmarks vary by industry, traffic source, and what counts as a conversion:
| Channel / Type | Typical Range | Notes |
|---|---|---|
| E-commerce (all traffic) | 1–3% | Purchase completion |
| B2B SaaS free trial | 3–5% | Trial signup |
| Landing pages (paid ads) | 2–5% | Lead generation |
| Optimized landing pages | 5–12% | Highly targeted traffic + tested copy |
| Email campaigns | 1–5% | Click-to-action |
| Organic search traffic | 2–4% | Higher intent than social |
| Social media traffic | 0.5–2% | Lower purchase intent |
The best benchmark is your own historical data. Improving from 1.8% to 2.4% is a 33% lift in conversions — that matters more than whether an industry report says "good" starts at 3%.
Common Mistakes
1. Mixing Up Visitors and Sessions
If your analytics shows 10,000 sessions and 7,500 unique visitors, using sessions gives a lower conversion rate than using unique visitors. Neither is wrong, but switching between them makes trends unreliable. Pick one and stick with it.
2. Ignoring Traffic Quality
A spike in social media traffic can dilute your conversion rate even if your page is performing the same. Always segment by traffic source before drawing conclusions.
3. Small Sample Sizes
50 visitors and 3 conversions is a 6% rate — but it is statistically meaningless. You need at least a few hundred conversions before the rate stabilizes. For A/B tests, use a sample-size calculator.
4. Counting the Wrong Conversions
Make sure you are counting unique conversions per visitor, not duplicate events. One visitor refreshing a "thank you" page should not count as two conversions.
5. Comparing Across Different Contexts
A 2% rate on a $500 product generates far more revenue than a 10% rate on a $5 ebook. Conversion rate alone does not capture value — pair it with revenue per visitor or average order value.
How to Improve Conversion Rate
These are general principles, not guaranteed fixes. The right approach depends on your specific situation.
- Improve page load speed. Faster pages keep more visitors. Test with tools like PageSpeed Insights.
- Simplify your call to action. One clear action per page. Remove competing links and distractions.
- Reduce form fields. Every extra field adds friction. Ask only what you need immediately.
- Add trust signals. Customer reviews, security badges, money-back guarantees, and clear return policies reduce hesitation.
- Match ad copy to landing page. If your ad promises "free shipping," the landing page should confirm it above the fold.
- Fix mobile experience. Test your page on a phone. Buttons should be easy to tap, text readable without zooming.
- Run A/B tests. Change one element at a time — headline, button color, page layout — and measure the impact with enough traffic for statistical significance.
Conversion Rate vs. Other Metrics
| Metric | What It Measures | Relationship to Conversion Rate |
|---|---|---|
| Click-through rate (CTR) | Clicks ÷ Impressions | Feeds traffic into your conversion funnel |
| Bounce rate | Single-page visits ÷ Total visits | High bounce = fewer chances to convert |
| Cart abandonment rate | Abandoned carts ÷ Carts created | Measures drop-off after add-to-cart |
| Cost per acquisition (CPA) | Ad spend ÷ Conversions | Rises when conversion rate falls |
| Revenue per visitor (RPV) | Revenue ÷ Visitors | Combines conversion rate + order value |
Each metric tells part of the story. Conversion rate is the "efficiency" metric — how well you turn attention into action.

Open CalculatorFrequently Asked Questions
How do you calculate conversion rate?
Divide conversions by total visitors, then multiply by 100. For example: 80 conversions from 4,000 sessions = (80 ÷ 4,000) × 100 = 2.0%.
What is a good e-commerce conversion rate?
Most e-commerce sites see 1–3%. The top 25% of sites typically exceed 3.5%. Your target depends on your price point, product category, and traffic sources.
Can conversion rate be over 100%?
Only if your counting is off — for example, counting conversions per session when a single session can trigger multiple conversion events. True visitor-to-goal conversion rates cap at 100%.
How often should I check conversion rate?
Weekly is enough for most sites. Daily data is noisy due to small sample sizes and day-of-week patterns. Monthly or quarterly reviews are best for spotting real trends.
Does conversion rate affect SEO?
Not directly. Search engines do not use conversion rate as a ranking factor. However, the user experience signals that drive conversion rate (page speed, clarity, mobile-friendliness) do overlap with factors search engines consider.
What is micro-conversion vs. macro-conversion?
A macro-conversion is the primary goal (purchase, signup). Micro-conversions are smaller steps that lead to it (adding to cart, viewing pricing, starting checkout). Tracking both helps you find where visitors drop off.
How do I calculate conversion rate for email?
Divide the number of desired actions (purchases, signups) by the number of emails delivered (not opened), then multiply by 100. Some teams divide by opens instead — just be clear about your denominator.
Is a low conversion rate always bad?
Not necessarily. If you sell high-value products ($10,000+), even a 0.5% rate can be very profitable. Conversion rate must be interpreted alongside average order value, revenue, and profit.
How is conversion rate different from engagement rate?
Engagement rate measures interactions (likes, comments, shares, time on page). Conversion rate measures goal completion. Engagement may lead to conversion, but they are distinct metrics.
Should I optimize for conversion rate or traffic volume?
Both matter. Doubling your traffic at the same conversion rate doubles conversions. Doubling your conversion rate at the same traffic also doubles conversions. Typically, improving conversion rate is cheaper than buying more traffic.
