Websites and the Importance of UX, UI, and Programming
Whether it's a website, microsite, or landing page, web design, UX, UI, and programming are key to making your website connect with visitors and drive sales. Here, we explain what all of this entails and why it's important.

The website remains the digital foundation
At Alterno Agency, we’ve been creating and managing websites for clients in Puerto Rico and beyond for over 15 years. During this time, we’ve seen everything evolve: technologies, platforms, and trends in web design. But one thing hasn’t changed: Your website remains the cornerstone of your digital presence.
Although everything these days seems to revolve around social media, artificial intelligence, apps, and automation, the reality is that even the most modern platforms ultimately lead you to a website.
Has this ever happened to you? You’re using an advanced app on your phone—like Netflix, Spotify, or Airbnb—and at some point the system tells you, “To make this change, please log in to your account on the website.” The website remains the central hub and headquarters of the business, where accounts, subscriptions, data, and essential processes are managed. Although mobile and responsive websites have come a long way, today more than 60% of global web traffic comes from mobile devices (Soax, 2024; Exploding Topics, 2024), and on some of the websites we manage at Alterno Agency, we’ve seen as much as 85% of traffic coming from mobile.
Even so, the desktop version remains the most comprehensive and robust platform. It’s where you can access the full range of features without the limitations imposed by screen size or certain mobile interfaces. Mobile makes things easier, but the desktop remains the platform where brands centralize and control their digital operations.

First things first: What types of websites are there, and what are they used for?
Although they are used interchangeably, not all websites are the same or serve the same purpose. Here are the differences you need to understand:
+
Website
Your digital headquarters. That’s where your brand, business information, full product lineup, SEO strategy, blog, campaigns, and reputation all reside. It’s your most important digital asset. Long-lasting.
+
Microsite
A mini-website for a specific purpose: launching a product, a campaign, or a promotion. It has a limited lifespan. It conveys a clear, direct, and strategic message.
+
Landing Page
A single page with a specific goal: to capture leads, generate sales, and schedule appointments. Highly focused on action and conversion.
+
E-Commerce
An online store that allows you to sell products or services directly online. It integrates product catalogs, shopping carts, payment platforms, and inventory systems. It can be a standalone website or part of a larger one, but it always focuses on online transactions and sales.
+
Web-Based Platforms or Solutions
Robust systems: CRMs, scheduling systems, educational platforms, and complex e-commerce sites. Many of these are web-based and accessible via a browser, even if they have an app.
Examples: Netflix and Spotify have apps, but their websites are still functional and necessary for sign-ups, account settings, payments, technical support, and so on.
+
Design isn't just about aesthetics; it's about creative direction.
When we talk about web design, we’re talking about the visual, creative, and strategic direction of the entire digital ecosystem: colors, fonts, styles, images, and icons. It’s what gives your brand visual cohesion and ensures consistency across your website, social media, email, and presentations.
+
UX (User Experience): Experience is everything.
UX isn't graphic design. UX is strategy, logic, empathy, data, and human behavior. It's about thinking about how your customer navigates your website, how they find what they're looking for, and how they achieve their goal without frustration.
A good UX is like walking into a well-organized store with clear signs, open aisles, and an easy path to the checkout. A bad UX is like walking into a place with no map and no signs, where you can't find what you're looking for.
On a website, UX is:
Clear Navigation
Easy-to-understand menus
Simple Forms
Logical Processes
Low friction
Just a few steps
A good UX increases conversions and satisfaction. A bad UX drives your customers away.
+
UI (User Interface): It's not just "pretty"—it's functional and strategic.
UI is indeed visual design, but it’s not the same as the overall design of the website. UI is the specific visual layer that shapes the user’s interaction with your website. It ensures that buttons are where they should be, that the contrast is clear enough to read, that icons are intuitive, and that the experience is enjoyable.
While visual design creates the identity, the UI provides the visual functionality that brings the UX to life. A good UI is the difference between a button that invites you to click it and one that goes unnoticed.
On a website, the UI is:
Clear and accessible buttons
Proper Contrast for Reading
A typeface that is easy on the eyes
Well-thought-out visual hierarchies
+
Programming: The Invisible Muscle That Makes It Happen.
In our experience, we've found that many people believe that when you design a website, there's some kind of magic printer that turns that design into a functional website overnight. Spoiler alert: it doesn't exist.
This is where programming comes in. But what is it?
Programming is the set of languages and code that brings any website, app, or digital platform to life. It’s what connects the visual elements with the functional ones.
+
Basic Web Development Languages:
HTML, CSS, JavaScript: The foundation of any website. Structure, styling, and interactivity.
PHP, Laravel (robust framework): For custom and robust projects.
React, Angular: Interactive solutions, SPAs (Single-Page Applications), dynamic platforms.
+
CMS (Content Management Systems) Platforms:
These systems make it easier and faster to create websites without having to code everything from scratch:
WordPress: The most popular and flexible platform. From blogs to complex websites.
Shopify: Focused on e-commerce, quick to set up.
Drupal: Robust, technical, ideal for institutions or complex projects requiring a much higher level of security.
These CMS platforms make it easy to manage content, online stores, blogs, and forms without relying 100% on advanced programming.
+
Why does all this matter so much?
Because your website isn't just your storefront—it's your business operating online. Poor UX causes you to lose leads. Poor UI makes you look outdated. Poor programming makes your site slow, insecure, and invisible to Google.
Studies confirm it: 75% of users judge a business’s credibility based on its website (HubSpot - Website Statistics), while 88% do not return to a website after a poor digital experience (Forbes - Why Bad Websites Drive Customers Away). Google also penalizes your search ranking if your website isn’t clear, fast, and secure. (Search Engine Journal - Google UX Ranking)

What have we learned at Alterno over the past 15 years?
Nothing can replace a well-designed website. That's why we've developed websites and platforms for:
Polytechnic University of Puerto Rico
Aba Laser Hair Removal
Ferrero (Ferrero, Nutella, Tic-Tac, Crunch)
Ferré Rangel Group
Puerto Rico Medical Defense Insurance Company (PRMD)
Puerto Rico Public Relations Association (ARPR)
Easeway
Professional Market Research, Inc. (PMR)
OPTI Manufacturing
And like these, there are many other brands that know it’s not enough to just have a nice-looking website—you need real expertise behind it. Ultimately, all projects have one thing in common: without UX, UI, and solid programming, the website won’t work as it should.
+
Conclusion: Everything is connected.
UX is experience. UI is perception and visual functionality. Design is identity. Programming is functionality. A website is strategy.
It’s all of these elements together that help your customers find what they’re looking for, make it easy for them, encourage them to come back, and get them to recommend you. That’s what we do at Alterno: we help brands be where their customers are, with the right experience, at the right time.
Transform your brand with Alterno Agency.
