These problems can add friction to finding information, contacting a business, signing up, or buying—but no single fix guarantees a particular conversion lift. The practical approach is to identify where real users struggle, then test a targeted improvement against the task they came to complete.
How to prioritize conversion problems
Start with a representative task—such as finding a product, submitting a contact form, or completing checkout—and follow it on desktop and mobile. Compare the experience with real user reports where available, then reproduce suspected issues in a controlled test. Give priority to problems that block a task, affect many users or devices, or exclude keyboard and assistive-technology users. Also weigh implementation effort and the risk of introducing regressions.

For performance, PageSpeed Insights is a starting point for examining a page, while Google also points to Lighthouse for page-experience assessment. Lab diagnostics can expose issues, but field data helps show how pages behave for actual visitors. Google says Core Web Vitals are used by its ranking systems; it also states that “There is no single signal” for page experience. A good score does not guarantee a top search ranking or a conversion increase. See Google Search Central’s page-experience guidance.
Benchmarks can reveal common usability weaknesses without predicting the outcome for a particular site. Baymard’s 2025 desktop ecommerce benchmark found 67% of the sites it assessed performed “mediocre” or worse; it covered 50,000+ UX performance scores across 130+ leading ecommerce sites. Its mobile benchmark overview, covering 138 major US and European mobile ecommerce sites, reported 62% “mediocre” or worse and 38% “decent”; none had an overall “good” implementation in that benchmark. These are ecommerce samples, not a census of websites in general. Desktop benchmark context and mobile benchmark context.
#1 Best Overall
1. Slow or unstable pages
A page that takes too long to become usable—or shifts while someone is trying to tap a control—can interrupt a task and make the site feel unreliable. Do not optimize by guesswork or assume a particular speed change will deliver a universal conversion uplift.
How to fix it
- Measure important pages and task flows, not only the homepage. Review Core Web Vitals and field experience alongside diagnostic results.
- Profile the actual bottleneck before changing code. Check for unnecessary resources, oversized assets, avoidable network requests, and ineffective caching.
- After making a change, test responsiveness and layout stability as well as load behavior. Confirm that the page still works across relevant devices and browsers.
Google’s PageSpeed Insights can help identify areas to investigate. Treat its results as diagnostic evidence, not a promise of business impact.
2. Navigation that makes people guess
Visitors should not have to infer what a menu label means, where a link leads, or how to return to a useful section. Navigation problems can make relevant information feel unavailable even when it exists.

- Use clear, consistent labels and headings that describe the destination or action.
- Provide more than one route to important content when appropriate, such as a hierarchical menu and site search.
- Make the current location and the next useful action understandable.
People do not all navigate the same way. W3C’s Web Accessibility Initiative says, “People navigate digital technology differently depending on their preferences, skills, and abilities.” Its navigation and finding guidance notes that hierarchical menus can be difficult for some users.
3. Controls and content that exclude some users
A menu, filter, link, or form that works only with a mouse or is not understandable to assistive technology can make a task impossible for some visitors. A visual review or automated scan by itself cannot establish that a whole task flow works for everyone.
How to fix it
- Test complete flows using a keyboard: move through controls, open and close menus, apply filters, submit forms, and check that focus remains visible and predictable.
- Give controls descriptive names and form fields meaningful labels. Use headings and other structure to make content easier to navigate.
- Provide a skip link around repeated content so keyboard users can reach the main content more directly.
- Include human review with keyboard and assistive technology in addition to automated checks.
W3C describes a range of interaction styles in its navigation guidance. For ecommerce flows, Baymard also recommends keyboard-operable filters and screen-reader context in its desktop UX guidance.
Rank #3
- Used Book in Good Condition
4. Forms that demand needless work or explain errors poorly
Every unnecessary field adds effort, and an unclear error can leave someone unsure how to proceed. The risk is especially consequential in checkout, where a user may have already invested time in selecting items and entering details.

How to fix it
- Remove inputs that are not needed to complete the task.
- Explain what each field requires, and use suitable input behavior for the data being requested.
- When validation fails, preserve the values the user already entered and put a clear correction message beside the affected field.
- Make the correction actionable: identify the problem and state what valid information is needed.
Baymard’s mobile checkout and form usability research identifies redundancy, missing field descriptions, and deficient error messages as recurring usability problem areas. Its checkout page is older, so use it as usability guidance rather than as a measure of current market prevalence.
5. Feedback that leaves people unsure whether an action worked
After a visitor submits a form, applies a filter, or starts a process, silence creates uncertainty: did the action succeed, fail, or remain in progress? Unclear feedback can prompt repeated clicks or cause someone to abandon the task.
How to fix it
- Show understandable success, failure, validation, and loading states.
- Associate a message with the action and, when relevant, the field that needs attention.
- Make important status changes perceivable to assistive technology, not only visually prominent.
W3C calls for helpful error and success messages that help people complete tasks and avoid confusion or disorientation. See its guidance on navigating and finding.

A mobile page can look polished and still make a task difficult if search is hard to find, a form is awkward to complete, or an important action is obscured. Review the whole journey on a small screen rather than assuming a responsive homepage proves the site works well on mobile.

- Test navigation, search, forms, cart, and checkout on small screens, including the transitions between steps.
- Keep key actions and relevant costs visible when users need them.
- Let users review and edit their entries, and ensure secondary controls do not cover the task.
- Check that input controls, messages, and menus remain usable with touch, keyboard, and assistive technology.
Baymard’s mobile ecommerce usability overview identifies navigation, on-site search, forms, and sitewide elements as areas for improvement in its ecommerce research. Its checkout research flags issues involving costs, shipping, account selection, and forms. These findings are useful prompts for an audit, not proof that every site has the same problems.

7. Interruptions that obscure the main task
An overlay that appears immediately or is difficult to dismiss can cover the content or controls a visitor came to use. A promotion may be relevant, but if it interrupts before someone can understand the page, it can add friction instead of helping.
How to fix it
- Avoid showing overlay dialogs as soon as a page loads.
- Make any necessary overlay easy to dismiss and ensure it does not trap or hide the main task.
- Review aggressive homepage advertising for distraction and usability costs.
Google includes intrusive interstitials among its page-experience considerations in Search Central’s guidance. Baymard advises against page-load overlay dialogs and reports that 59% of sites in its 2021 homepage UX research used overly aggressive homepage ads; that is a study-specific historical finding, not a universal current rate. See Baymard’s usability best practices.
Turn the audit into a testable fix
For each suspected mistake, record the affected task, the users and devices involved, and whether the issue appears in field data, a lab test, or direct usability review. Fix a confirmed obstacle, then repeat the same task under comparable conditions. Check that the change removes the friction without creating a new accessibility, performance, or usability problem. Measure the outcome on your own site rather than assigning an expected conversion gain based on an unrelated benchmark.
