FAQ

FAQ

Which is better, a responsive website or a mobile app?

In terms of cost-effectiveness, responsive web design has the advantage. Apps are expensive to develop and must be built separately for iOS and Android. A responsive website, on the other hand, works on every platform with a single development effort, and updates take effect immediately. Unless push notifications are a core feature, we recommend responsive web design.

Can you convert my existing PC site to a responsive one?

Yes. You can convert to responsive while keeping your existing design, or take the opportunity to renew the design as well. We analyze your current site and propose the best approach.

How long does production take?

It depends on the number of pages and features. A simple landing page takes 1–2 weeks, an SME website 3–4 weeks, and large projects with complex features require separate discussion. We will give you an exact schedule during the consultation.

How does maintenance work?

Every project includes a free maintenance period. During this period, bug fixes and minor text/image changes are free. After the period ends, you can sign a maintenance contract at a reasonable cost.

Do you also provide SEO (search engine optimization)?

Basic SEO setup (meta tags, semantic markup, sitemap, etc.) is included in every project. Advanced SEO services such as keyword analysis and content optimization are offered separately through our SEO service, so please ask during your consultation.
