What Is a Conversion Rate?
A conversion rate is the percentage of visitors who do something you want them to do. That action is called a conversion. It might be a purchase, a newsletter sign-up, a free trial, a booked call or a download.
Google Analytics calls these important actions key events, and describes key events as the events you mark because they track the actions that matter most to your business.1 Which actions count depends entirely on your goals.
Conversion rate matters because it shows how well your website or campaign turns attention into results. Two sites with the same traffic can produce very different revenue if one converts twice as well as the other.
How to Calculate a Conversion Rate
The formula is simple: divide conversions by visitors and multiply by 100.
Conversion rate (%) = (Conversions ÷ Visitors) × 100
In an illustration, an online shop has 10,000 visitors in a month and 200 orders. Its conversion rate is 200 ÷ 10,000 × 100 = 2%. A newsletter page with 5,000 visitors and 150 sign-ups converts at 3%.
Be clear about what you count. Some tools divide by sessions (visits), others by users (people). A person who visits three times and buys once gives a different rate depending on which you use. Pick one definition and use it consistently, so you compare like with like.
Why Conversion Rate Is So Powerful
Improving conversion rate grows results without buying more traffic. In our illustration, the shop with 10,000 visitors and an average order of $50 earns $10,000 a month at a 2% conversion rate.
If the same shop raises its conversion rate to 2.5%, it gets 250 orders and $12,500, an extra $2,500 a month with exactly the same visitors. Getting the same increase from traffic alone would need 2,500 more visitors every month.
What Counts as a Good Conversion Rate?
There is no universal good number, because conversion rates vary hugely by industry, price, product and traffic source. A free newsletter sign-up will usually convert far better than an expensive product. Visitors who searched for your brand name convert better than people who arrived from a general article.
The most useful benchmark is your own past performance. Track your rate over time, by page and by traffic source, and work to improve it. Published industry averages can give a rough idea, but they often mix very different businesses and definitions.
Types of Conversions
Not every conversion is a sale, and smaller steps often lead to bigger ones.
| Type | Examples | Why it matters |
|---|---|---|
| Macro conversions | Purchase, paid subscription, signed contract | Directly produce revenue |
| Micro conversions | Newsletter sign-up, free trial, add to cart, calculator use | Show interest and often lead to a macro conversion |
| Lead conversions | Contact form, quote request, booked call | Start a sales conversation |
Tracking micro conversions helps you spot where people drop off. If many people add items to their cart but few complete checkout, the problem lies in the checkout, not in the product page.
Why Visitors Don’t Convert
Most visitors leave without converting, and knowing why is the first step to fixing it. The Baymard Institute, which studies online checkouts, puts the average documented online shopping cart abandonment rate at about 70%, based on 50 studies.2
| Reason shoppers gave for abandoning an order | Share of US shoppers |
|---|---|
| Extra costs, such as shipping, tax or fees, were too high | 40% |
| Delivery was too slow | 20% |
| Didn’t trust the site with card information | 19% |
| The site wanted them to create an account | 18% |
These figures exclude people who said they were just browsing, which Baymard found was the most common reason overall.2 Many of the remaining reasons are fixable: show the full price early, offer guest checkout and make security and delivery details clear.

Conversion improvements usually come from removing friction and building confidence. These changes help on most websites.
Make the offer clear
Visitors should understand within seconds what you offer, who it is for and what to do next. Use one clear call to action per page, with wording that says what happens when they click.
Show the full cost early
Surprise costs at checkout are the top reason for abandoned orders in Baymard’s research.2 Show shipping, taxes and fees as early as possible.
Simplify forms and checkout
Ask only for the information you need. Offer a guest checkout, because being asked to create an account drives some shoppers away.2
Speed up your pages
Slow pages lose visitors before they even see your offer. Google says its ranking systems use Core Web Vitals, which measure loading speed, responsiveness and visual stability.3 Faster pages help both visitors and search visibility.
Build honest trust
Clear contact details, secure payment, a fair returns policy and genuine reviews all reduce hesitation. Reviews must be real: the FTC says endorsements must reflect the honest opinions or experiences of the people giving them, and you cannot make an incentive depend on a review being positive.4
Match the page to the visitor’s intent
A visitor from a “what is” search wants an explanation first, not a hard sell. A visitor searching for a product by name wants to buy. Our explainer on search intent shows how to match pages to what people are looking for.
Landing Pages That Convert
A landing page is the page a visitor first arrives on from an ad, an email or a search result. Because it is the first impression, it has a large effect on conversion rate.
A strong landing page keeps the promise that brought the visitor there. If an ad mentions a free guide, the page should lead with that guide, not a general homepage. It focuses on one goal, removes distractions such as unrelated links, and explains the benefit in plain words before asking for anything.
Different traffic sources often deserve different landing pages. Someone clicking a newsletter link already knows you; someone clicking an ad may need more reassurance before they act.
Mobile Conversion
Many visitors now arrive on a phone, and mobile pages often convert worse than desktop ones. Small screens make long forms, tiny buttons and slow pages more painful.
- Make buttons easy to tap and keep the main action visible without scrolling too far.
- Shorten forms and use the right keyboard for each field, such as a number pad for phone numbers.
- Offer fast payment options that avoid typing card details on a small screen.
- Test on real phones, not just a shrunken desktop browser.
Comparing your mobile and desktop conversion rates in analytics shows quickly whether mobile needs attention.
Conversion Rate for Content Sites
For a site that publishes articles, the most important conversion is often a sign-up, not a sale. Readers who join a newsletter come back, trust you more and are more likely to act later.
Useful conversions for content sites include newsletter sign-ups, use of free tools such as calculators, and clicks to related guides. Tracking these shows which topics build an engaged audience, which is more useful than page views alone. Placing a relevant offer in the article, such as a checklist that matches the topic, usually works better than a generic pop-up.
Testing Changes the Right Way
The safest way to improve conversions is to test changes rather than guess. In an A/B test, half your visitors see the current page and half see a changed version. You then compare their conversion rates.
- Change one thing at a time, such as a headline or button, so you know what made the difference.
- Wait for enough data. Small samples can show differences that are just chance.
- Run tests for full weeks, because behavior often differs between weekdays and weekends.
- Write down what you learn, including tests that did not work.
If your site has little traffic, a full A/B test may take too long to give a clear answer. In that case, watching how real visitors use the page, through recordings and heatmaps, and fixing obvious problems is often more practical.
Writing Calls to Action That Work
A call to action is the button or link that asks the visitor to convert, and its wording matters. Vague labels such as “Submit” or “Click here” tell people nothing about what happens next.
Better labels describe the result: “Get the free checklist”, “Start my free trial” or “See my monthly payment”. Place the main call to action where people naturally look after reading the key benefit, and repeat it further down long pages so readers do not have to scroll back up.
Keep the number of competing calls to action low. When a page asks visitors to do five different things, many choose none of them.
Turning Insights Into a Routine
Conversion improvement works best as a regular habit rather than a one-off project. Review your key pages monthly, look at where visitors drop off, pick one problem to fix and record the result.
Over a year, a dozen small fixes can add up to a much higher conversion rate. Each lesson also makes the next page you build better from the start.
Measuring Conversion Rate With Analytics
To track conversion rate, you first need to tell your analytics tool which actions count. In Google Analytics, you mark important events, such as a purchase or sign-up, as key events.1 The tool then reports how often they happen.
Break your conversion rate down by traffic source, device and page. A low rate on mobile but a healthy one on desktop points to a mobile problem. A low rate from one campaign may mean that campaign attracts the wrong audience, not that your page is weak.
Look at the whole journey, too. Content that rarely converts directly may still introduce people who convert later. Our explainer on content marketing explains how content supports conversions over time.
Conversion Rate Optimization Mistakes
Some common tactics raise a number in the short term but damage trust or results.
- Fake urgency or scarcity. Countdown timers that reset and “only 2 left” messages that are not true can mislead customers and erode trust.
- Hiding costs until the end. It may get more people to checkout, but more of them leave.
- Chasing the wrong conversion. More sign-ups are only good if they lead to real customers.
- Copying other sites’ tests. What worked for one audience may not work for yours.
- Ignoring speed and mobile. A beautiful page that loads slowly on a phone will still lose visitors.
Conversion Rate and Email
Email is often the channel that turns interested visitors into customers over time. Many visitors are not ready to buy on their first visit. Inviting them to join a newsletter gives you a way to stay in touch until they are.
That makes the newsletter sign-up one of the most valuable micro conversions to track and improve. Our explainer on email marketing covers how to grow and use a list well, and the rules for doing it legally.
A Simple Conversion Checklist
Before you run tests, check the basics on your most important pages.
- Does the headline say clearly what you offer and for whom?
- Is there one obvious next step?
- Does the page load quickly on a phone?
- Are prices, delivery times and extra costs shown up front?
- Is the form as short as possible?
- Are contact details, policies and genuine reviews easy to find?
- Is the conversion being tracked correctly in your analytics?
Key Terms Explained
- Conversion: an action you want visitors to take, such as a purchase or sign-up.
- Key event: Google Analytics’ term for an action important to your business.
- Cart abandonment: when a shopper adds items to a cart but leaves without buying.
- A/B test: comparing two versions of a page by showing each to a share of visitors.

The Bottom Line
Your conversion rate shows how well your site turns visitors into results. Define the actions that matter, track them consistently and fix the obvious friction first: unclear offers, hidden costs, slow pages and long forms. Then test changes one at a time, because small, honest improvements can add as much as a big rise in traffic. For more, browse our marketing explainers.
Frequently Asked Questions
Divide the number of conversions by the number of visitors or sessions, then multiply by 100. For example, 200 orders from 10,000 visitors is a 2% conversion rate.
It depends on your industry, price and traffic source, so there is no single good number. The best benchmark is your own rate over time.
A conversion is any action you want visitors to take. Google Analytics uses the term key event for actions you mark as important to your business.
In Baymard Institute’s research, the top reason was extra costs such as shipping, tax and fees. Slow delivery, trust concerns and forced account creation also played a part.
Fix obvious friction first: show full costs early, simplify forms, offer guest checkout and speed up your pages. Then test further changes one at a time.
Slow pages can lose visitors before they see your offer. Google also uses Core Web Vitals, which include loading speed, in its ranking systems.
