What is UX?

UX (User Experience) is the totality of impressions and feelings a person has when using a website, application, or digital product. It encompasses ease of navigation, content readability, speed of operation, interface intuitiveness, and overall satisfaction with the interaction. Good UX means the user achieves their goal quickly, smoothly, and with pleasure.

UX is not limited to aesthetics — it is primarily about functionality, usability, and efficiency. A beautiful site where the phone number cannot be found has bad UX.

Why is UX important?

UX directly impacts a website's business outcomes — from Google rankings, through conversion, to customer loyalty. Research shows that:

88% of users do not return to a site after a bad experience
53% of mobile users leave a site that takes longer than 3 seconds to load
Every $1 invested in UX returns an average of $100 (according to Forrester Research)
Improving UX can increase conversion by 200–400% without changing site traffic

UX and SEO

Google increasingly links UX with search result rankings. Core Web Vitals — an official ranking factor — is a direct metric of user experience, measuring loading speed (LCP), responsiveness (INP), and visual stability (CLS).

Beyond Core Web Vitals, UX impacts SEO indirectly through behavioral signals:

Lower bounce rate — users do not flee from a well-designed site
Longer session time — engaging UX encourages exploration
Higher CTR — a professional look in SERP (rich snippets, breadcrumbs) builds trust
More return visits — satisfied users come back, generating loyalty signals

UX and conversion

The direct impact of UX on conversion is one of the best-documented phenomena in digital marketing. More about how UX design translates to conversions can be found in our guide. UX optimization is often the fastest path to increasing website revenue:

Simplifying a form from 11 to 4 fields can increase conversion by 120%
Improving loading speed by 1 second increases conversion by approximately 7%
Adding social proof (reviews, client logos) increases trust and conversion by 15–35%
Clear CTAs (Call to Action) with an unambiguous message improve click-through by 30–90%

How does UX design work?

The UX design process consists of several stages:

1. User research (UX Research)

Data analysis — Google Analytics, Microsoft Clarity, heatmaps
Usability testing — observing users performing tasks on the site
Interviews and surveys — direct feedback from users
Conversion path analysis — identifying drop-off points

2. Information architecture

Content hierarchy — logical layout of pages and subpages
Navigation — intuitive, enabling access to any content in a maximum of 3 clicks
Labeling — understandable category and section names

3. Interface design (UI)

Layout — placement of elements on the page
Typography — readable fonts, appropriate size and contrast
Color scheme — a consistent palette supporting business goals (e.g., CTA color)
Whitespace — adequate empty space to facilitate scanning

4. Testing and iteration

A/B tests — comparing interface element variants
Testing on different devices — desktop, tablet, smartphone
Continuous optimization — UX is a process, not a one-time project

How to improve website UX?

Speed and performance

Optimize Core Web Vitals — LCP < 2.5s, INP < 200ms, CLS < 0.1 (see our guide on Core Web Vitals and positioning)
Consider Static Site Generation for blazing-fast loading
Use a CDN and optimize images (WebP/AVIF, lazy loading)

Navigation and readability

Ensure responsive design — over 60% of traffic is mobile
Apply visual hierarchy — headings, paragraphs, lists, highlights
Add breadcrumbs and table of contents in longer articles
Ensure readable typography — min. 16px on mobile, proper contrast

Trust and conversion

Add social proof — reviews, client logos, certifications
Display contact information in a visible location
Use clear, unambiguous CTAs — the user must know what to do next
Eliminate intrusive pop-ups and interstitials

Accessibility

Ensure proper text-to-background contrast (WCAG 2.1 AA)
Add alt text to all content images
Enable keyboard navigation
Ensure readability for screen readers
