Why is BIGSEO your web design agency?
Over 10 years creating websites that sell
We have been building websites for over a decade that not only impress, but also work. We have accompanied brands that needed web design with criteria, strategy and a solid foundation for growth. Each project is born with a clear vision: to create a site that delivers results from day one.
Design, development and SEO teams working together
At BIGSEO, designers, developers and SEO specialists work together as an integrated team. Our experience in web design and SEO allows us to create websites that combine aesthetics, technical performance and SEO strategy. This alignment ensures that every decision contributes to the organic growth and efficiency of the project from day one.
Experience in complex and regulated sectors
At BIGSEO, we work with designers, developers, and SEO specialists who collaborate from the outset to build websites that combine aesthetics, technical performance, and strategy. This integration ensures a fast, optimised website that is ready to scale, where every decision contributes to the organic growth and efficiency of the project.
Scalable websites that are easy for your team to manage
We create platforms that grow at the same pace as your business and that your team can manage without relying on constant technical support. We prioritise usability, performance and scalability so that your website is stable, fast and easy to manage. For us, a web design agency should simplify processes, not add more layers of complexity. And that is the basis of how we work.
Complementary services that boost your website
CRO: continuous improvements to increase conversions
We analyse how your users navigate your website, optimise each key point in the journey, and apply CRO improvements that eliminate friction, refine the experience, and progressively increase conversions. This continuous approach, based on real data, allows us to make strategic decisions and turn your website into an increasingly efficient sales channel.
With the best SEO positioning for your website design
We design websites for SEO positioning from the very first draft. We integrate SEO architecture, content, and technical performance to create sites that scale easily and that Google can understand from the get-go. We combine our expertise in SEO and web design and development to build balanced pages: visible to Google and fluid for the user.
Advertising on Google and networks to attract qualified traffic
We drive your growth with paid campaigns designed to attract users with real intent. We understand that design and traffic must go hand in hand: a powerful website needs qualified visitors, and good campaigns need a website that is ready to convert. By integrating Google Ads and social ads, we boost conversions and accelerate return on investment from the very first impact.
Website maintenance and technical updates
We take care of maintenance so that your website remains secure, stable, and running at full capacity. We manage updates, technical improvements, and continuous monitoring to prevent problems and ensure that your site continues to evolve. With this support, your website maintains the quality it needs to rank well and continue generating business without interruption.

FAQs about web design and development
We want to help you make an informed and valuable decision. We answer several common questions.
How much does a professional website cost?
The price depends on the type of website, the complexity of the design, the necessary functionalities, and whether it includes e-commerce, automation, or CRM integration. Before giving you a figure, we analyse your project to ensure that you only pay for what you really need. We create custom websites, not generic templates.
How long does it take to get a website ready?
A simple corporate website can be ready in a few weeks. A more comprehensive project—with e-commerce, integrations, or custom development—requires more time to ensure design, UX, performance, and SEO. The deadline is always defined from the outset and we work with a clear schedule to avoid delays.
What technologies do you use to develop websites?
We mainly work with WordPress, WooCommerce, and modern technologies such as HTML5, CSS3, JavaScript, PHP, APIs, and advanced builders when necessary. We choose each tool according to your project, not the other way around. We always prioritise scalability, speed, and ease of management for your team.
Can I request changes after delivery?
Yes. All our projects include a review and adjustment phase after delivery to fine-tune the design, content and functionality. We also offer maintenance plans to ensure your website continues to evolve smoothly and is always up to date and secure.
Can you adapt my website to SEO and marketing campaigns?
Of course. We design websites with SEO in mind from the very first draft: architecture, speed, content hierarchy and title structure. We can also integrate your website with Google Ads, social ads, or email marketing campaigns so that your entire digital ecosystem works in a unified and conversion-oriented manner.
Do you only work with WordPress?
WordPress is our main CMS because it offers flexibility, scalability, and ease of use for most businesses. However, we also work with other solutions depending on the project: custom landing pages, hybrid systems, API integrations, or specific developments when the business requires it.
