The conversion rate formula
Conversion rate = conversions ÷ visitors × 100
Example: 40 sales from 2,000 visitors is 40 ÷ 2,000 × 100 = 2% conversion rate. At the same rate, 60 sales need 60 ÷ 2 × 100 = 3,000 visitors.
What is conversion rate?
Conversion rate shows how well a site, page or campaign turns visitors into results. It is often the cheapest number to improve: raising it lowers the cost of every sale without spending more on ads.
Decide what counts before comparing: visitors or sessions, purchases or sign-ups, and the same period for both. Analytics tools differ, so compare rates from one source.
What is a good conversion rate?
It depends on the channel, the campaign objective and what you sell, so compare against your own history first. For scale, these are the typical figures from the largest recent studies of ad accounts and shops.
| Where | Typical | Source |
|---|---|---|
| Google search ads, conversions per click, US From 2.64% (finance and insurance) to 16.22% (animals and pets) | 8.18% | WordStream, 2026 Google Ads Benchmarks |
| Meta lead campaigns, leads per click, US Apr 2025 to Jun 2026 | 8.54% | WordStream, 2026 Facebook Ads Benchmarks |
| Meta, purchases per click, ecommerce brands Aug 2025 to Jul 2026 | 1.53% | Triple Whale, Facebook ad benchmarks (2026) |
| Ecommerce sites, purchases per visitor, worldwide Past 12 months as of Oct 2026; from 0.69% (luxury) to 5.38% (beauty) | 2.68% | Dynamic Yield, conversion rate benchmarks |
How to raise your conversion rate
- Make the page answer what the ad or search promised, in the first lines.
- Show the price, shipping and the next step clearly.
- Remove steps and form fields that aren't needed.
- Look at the rate by source: a low average often hides one channel that brings visitors who never buy.
What conversion rate doesn't tell you
- A rate hides volume: 10% of 20 visitors is two sales.
- Tracking that misses visitors who decline cookies or block scripts changes the rate, so compare it from one tool over time.

Frequently asked questions
How do you calculate conversion rate?
Divide conversions by visitors and multiply by 100. 40 sales from 2,000 visitors is 2%.
How many visitors do I need for a sales target?
Divide the sales you want by the conversion rate and multiply by 100. For 100 sales at 2.5% you need 100 ÷ 2.5 × 100 = 4,000 visitors.
Should I use visitors or sessions?
Either, as long as you use the same one every time. A visitor can come back in several sessions, so a rate per session is lower than a rate per visitor.
How does conversion rate affect CPA?
CPA = CPC ÷ conversion rate. Doubling the conversion rate halves the cost of each conversion at the same CPC.
