If you are a marketing manager or run an SME in Colombia, you have surely been told "you need a page that sells". And it's true. But to achieve this you must understand two disciplines that cross all the time and are not the same thing: design and Web Development.
Here I explain, in plain language, how they differ, how they complement each other and when to prioritize each one so that your investment pays off.
What is web design?
Web design focuses on how your site looks and feels to the user. It works on visual identity, information hierarchy, legibility, color, photography, microcopy that leads to action and navigation architecture. A good design is not an ornament: it reduces friction, gives confidence and improves conversion because it helps the visitor to quickly understand what you offer and what step to follow.
What is Web Development?
He Web Development is the technical construction of your site: the code that makes it work, the integration with WordPress and WooCommerceThe main focus is on the loading speed, security, scalability and everything that happens "behind the scenes" to make the experience stable on mobile and desktop. Here live integrations with payment gateways, ERP/CRM, databases, forms, automations and custom components in PHP, JavaScript, HTML and CSS. Without solid development, the best design falls down due to poor performance, bugs and vulnerabilities.
Web Design vs. Web Development: quick comparison
| Appearance | Web design | Web Development |
| Central focus | Experience and aesthetics | Functionality and performance |
| Deliverables | Prototypes, layout, UI guides | Code, integrations, panels and APIs |
| Tools | Figma, typographies, design systems | WordPress, WooCommerce, PHP, JS, HTML, CSS |
| Key metrics | CTR on buttons, scroll, time on page | Core Web Vitals, speed, uptime, bugs |
| SEO Impact | UX, content hierarchy, interlinking | Indexability, schema, response times |
| Risks if it fails | Nice" site that does not convert | Unstable, slow or insecure site |
| Hidden costs | Rework due to lack of UX validation | Maintenance due to bad coding practices |
How design and development complement each other in a real project
In a professional project, design and Web Development progress in parallel but with control gates. First we define content strategy, architecture and wireframes; then we design the interface; finally we build the optimized and secure site. At Gulupa Digital we work this way in WordPress and WooCommerce so that the deliverable is not only beautiful, but also fast, stable and easy to self-manage by your team.
Impact on SEO and sales
Design influences the intent and clarity of the message; web development affects speed, indexing and structured markup. Google today rewards sites with good experience and low time: if the product card is understood the first time and the server responds in milliseconds, your conversion probability and your organic ranking improve. This combination is what turns your website into a commercial channel, not a digital brochure.
Common mistakes to avoid
One of the most costly mistakes is to start "just with design" and in the end discover that the CMS does not support what you promised in sales, or that the checkout is broken on mobile. The opposite also happens: programming at full speed without a clear interface guide and ending up with a "heavy" site without visual coherence. The way out is to align business objectives, UX and web development from day one, with usability testing and technical QA before publishing.
When to prioritize design or development?
If your bounce rate is high and no one understands your proposal, prioritize redesign, content ordering and microcopying. If your traffic is growing but the site is slow, the cart is failing or security is weak, prioritize Web DevelopmentCore Web Vitals optimization, code refactoring, cache, CDN, cleanup, etc. plugins and server hardening. In practice, the best results come when you improve both fronts with a clear roadmap.

Quick questions
Can I have a good design without web development?
Yes, but it will be fragile. Without a Web Development you will have problems with speed, security and scalability. That translates into lower sales and higher maintenance costs.
What is the estimated delivery time?
Between 4 and 8 weeks depending on complexity. We define a plan with clear dates and deliveries in stages.
What about good web development without design?
It will work, but it won't persuade. Without clear UX/UI, your users get lost, don't find what they're looking for and abandon before checkout. The winning equation combines both from the start.
How much does a web development cost and what does it depend on?
It depends on the scope: number of pages, if there is a store, integrations and contents. We give you a closed budget according to your goals.
Will the website look good on mobile or only on desktop?
Yes, we do everything with responsive web design so that it looks and works flawlessly on mobile, tablet and desktop.
