Your conversion rate is the share of visitors who take the action you want, such as buying, booking or calling. Good user experience, or UX, removes the small frictions that stop people from doing so.
This guide covers six UX fixes, from speed to forms. It uses guidance from web.dev and NN/g, and it ends with a checklist you can run on one page this week.
Conversion rate is conversions divided by visitors. To raise it, find where visitors drop out, then fix that step. The usual suspects are slow pages, an unclear main action, long or confusing forms and a clumsy checkout. Change one thing at a time and measure the result with your own data.
⚡ Key Takeaways
- Conversion rate = conversions divided by visitors, shown as a percentage.
- web.dev says well-designed forms help users and increase conversion rates.
- web.dev advises making guest checkout the default and not asking for data you do not need.
- Good Core Web Vitals targets are an LCP within 2.5 seconds, an INP of 200 milliseconds or less and a CLS of 0.1 or less.
- Test with real visitors, because lab checks alone miss real-world problems.
What Is Conversion Rate, and Where Does UX Fit?
The formula is simple. If 1,000 people visit a page and 25 submit the form, the conversion rate is 2.5%. These numbers are made up to show the maths.
UX affects the rate because every step asks something of the visitor. Each unclear label, slow load or extra field is a reason to leave. So, the job is to remove reasons, not to add tricks.
Fix 1: Speed Up the Page to Lift Your Conversion Rate
web.dev sets three targets for a good experience. Largest Contentful Paint should occur within 2.5 seconds. Interaction to Next Paint should be 200 milliseconds or less. Cumulative Layout Shift should be 0.1 or less. It suggests judging them at the 75th percentile of page loads.
If the largest element loads late, a detailed method is in this guide to fixing Largest Contentful Paint.
Fix 2: Make One Main Action Obvious
A page with five equal buttons gives visitors five decisions. Instead, pick one main action per page, such as Book a call or Add to cart. Give it the strongest visual weight, and make other links quieter.
Also, use button text that says what happens next. NN/g describes a government complaint form that ended with two buttons labelled Preview and Clear Form. It points out that most users would expect Submit or at least Next. Clear labels remove that doubt.
Fix 3: Cut Form Fields and Remove Friction
web.dev’s checklist says, “Don’t ask for data you don’t need.” It also advises asking for names with a single input unless you have a good reason not to, and not enforcing Latin-only characters for names.
In fact, every extra field is another chance to quit. Ask yourself what you will really use. If you never call the customer, you may not need a phone number.
Fix 4: Label Fields and Use Autofill
web.dev advises using meaningful HTML elements and labelling each field with a <label>. It also recommends the type and autocomplete attributes, so browsers can fill in details for people.
It adds a few practical tips. For example, validate data while the person types, not only on submit. Disable submit buttons once they are tapped, so a double tap does not send two orders.
Fix 5: Simplify Checkout
For shops, web.dev advises making guest checkout the default and making account creation simple after checkout is complete. It also suggests showing progress through the checkout in clear steps with clear calls to action.
Moreover, it recommends limiting exit points by removing clutter and distractions, and showing full order details with easy adjustments. In practice, then, a checkout page should feel like a short, quiet path.
Fix 6: Test With Real Visitors and Repeat
web.dev says to test in the field as well as the lab, using page analytics, interaction analytics and real-user performance measurement. It also advises testing on a range of browsers, devices and platforms.
Finally, change one thing at a time so you know what helped. For related work on people who leave quickly, see these ways to reduce bounce rate.
Accessibility Also Supports Your Conversion Rate
After all, a page that people cannot use will not convert them. Clear labels, readable text and keyboard-friendly forms help everyone, including people with disabilities. For specific checks, see these best practices for WCAG compliance in WordPress.
A Made-Up Example
First, imagine a small furniture shop whose checkout converts 1.2% of visitors. The owner finds that the form asks for an account password and a phone number. Both are removed, guest checkout becomes the default and a progress bar is added.
A month later, the owner compares the same page with the same traffic source. These numbers and this shop are invented. The example shows the method, not a promised increase.
Conversion Rate UX Checklist
- Measure the current conversion rate of one page first.
- Check LCP, INP and CLS against web.dev targets.
- Choose one main action and make it clear.
- Remove form fields you will not use.
- Label every field and add autocomplete attributes.
- Offer guest checkout and show progress.
- Test with real visitors and compare after a few weeks.
Conclusion
In short, raising your conversion rate is mostly about removing friction. Speed, one clear action, short forms and a simple checkout are the places to start, and each one is backed by web.dev guidance.
Pick one page this week, measure its rate and fix the weakest step. Teams that want an outside view can look at conversion rate optimization support.
Frequently Asked Questions About Conversion Rate
How do I calculate conversion rate?
Divide the number of conversions by the number of visitors, then multiply by 100. For example, 25 sign-ups from 1,000 visitors is 2.5%.
Does UX really affect conversion rate?
web.dev says well-designed forms help users and increase conversion rates. The size of the effect depends on your site, so measure your own results.
Should I make guest checkout the default?
web.dev advises it, and suggests making account creation simple once checkout is complete.
How long should I test a change?
Long enough to collect a fair number of visits from the same traffic source. Compare the same page before and after, and change only one thing at a time.
What is a good conversion rate?
There is no single number. It depends on your industry, traffic source and offer. Compare a page with its own past results.
