How long does it take to create a website with Slash.lu?
A standard SME showcase site: 4–8 weeks. Advanced e-commerce / complex app: several months. After discovery, we deliver a precise schedule with milestones and deliverables.
What is the typical cost of a web project with Slash.lu?
The price depends on features, design, content, integrations, and deadlines. We provide a custom quote after qualification (objectives, budget, priorities).
Do you use WordPress or alternatives?
We favor Astro.js for speed and security. For content editing, we integrate headless CMSs (Contentful, Sanity, etc.) via API, avoiding the bulk of traditional CMSs.
Do you offer Search Engine Optimization (SEO) in Luxembourg?
Yes. Semantic architecture, markup, sitemaps, schemas, internal linking, content targeting Google.lu/Google.fr, and Core Web Vitals optimization are natively integrated.
Do you create multilingual websites adapted to Luxembourg?
Yes. Proper internationalization (FR/DE/EN/LU), translated URLs, content management by language, multi-region SEO, and UX adapted to different cultures.
Do you offer maintenance and support after launch?
Yes. Security patches, updates, backups, monitoring, fixes, minor enhancements, and prioritized support according to the chosen plan.
Can you integrate my existing CRM or e-commerce solution?
Yes. Secure integrations (Salesforce, HubSpot, Pipedrive), headless Shopify, payment gateways (Stripe/PayPal), ERP, email tools, etc.
What is a website audit and when do I need one?
An audit analyzes performance (CWV), security, accessibility (WCAG), SEO, UX. Useful if the site is slow, poorly indexed, has recurring errors, or before a redesign.
How do you ensure the loading speed of my web pages?
We use Astro.js to generate ultra-fast static sites, optimize images, minimize code, use a global CDN by default, and ensure compliance with Google's Core Web Vitals for a smooth user experience.
Do you offer website migration services?
Yes, we manage the complete migration of your existing site to our high-performance platform, ensuring secure content transfer, redirecting old URLs to preserve your SEO, and post-migration testing.
Do you offer training to manage my site after delivery?
Yes, we offer personalized training sessions for you and your team on using the headless CMS, updating content, best maintenance practices, and understanding performance reports.
What is your policy regarding digital accessibility (WCAG)?
Accessibility is a priority. We develop our sites according to WCAG 2.1 AA standards, ensuring correct semantic structure, adequate color contrasts, keyboard navigation, and compatibility with screen readers.
Can I see examples of websites you have created?
Yes, you can find a selection of our work in the Portfolio section of our site. We are proud to showcase our expertise through detailed case studies outlining the challenges, solutions, and results achieved for our clients.
What are the benefits of a 'headless' website?
A headless site separates the frontend (user interface) from the backend (content management). This allows greater design flexibility, ultra-fast performance, better security, and the ability to deliver content across multiple platforms (web, apps, IoT).
Do you work with external communication agencies or designers?
Yes, we frequently collaborate with PR agencies, graphic designers, and other specialists. We can integrate their work or include them in our process for projects requiring complementary expertise.
What analytics and tracking tools do you integrate?
We integrate analytics tools according to your preferences (Google Analytics, Matomo, etc.) and set up tracking for essential events (forms, clicks, conversions). This is part of our standard configuration to allow you to measure your site's effectiveness.
How do you manage contact forms and data protection?
Forms are processed via secure services (like Netlify Forms or custom backends) with client and server-side validation. We comply with GDPR by encrypting data, limiting access, and providing necessary legal notices.
What type of technical support do you offer after launch?
We offer support packages including priority responses, quick fixes, and minor enhancements. An SLA contract can be established to guarantee specific response and resolution times based on your critical needs.
How do you approach design (UX/UI) for a new site?
Our process starts with user research and objective analysis. We create wireframes to structure information, then interactive prototypes to validate the experience (UX). The visual design (UI) is then developed in alignment with your brand identity.
What is a PWA and do you offer this type of site?
A PWA (Progressive Web App) is a website that offers a native app-like experience (offline, notifications, home screen icon). Yes, we can develop your site as a PWA to improve engagement and accessibility.
How do you optimize sites for local search engines (Google.lu, Google.fr)?
We combine solid technical architecture (semantics, speed) with a content strategy targeting local queries and a presence in relevant directories. We manage hreflang tags for multilingual sites and local schemas to improve visibility on Google.lu/Google.fr.
What is the difference between a showcase site and an e-commerce site?
A showcase site presents your company, services, or products without direct online sales. An e-commerce site allows you to sell products or services directly via the site, requiring a cart, payment, and inventory management system.
Do you offer web hosting solutions?
Yes, we offer optimized, secure, and scalable hosting solutions adapted to your site's technology (static, headless). We manage configuration, continuous deployment, and infrastructure monitoring.
How do you handle security updates for my site?
For static Astro.js sites, the risk is minimal. For dynamic components or headless CMSs, we monitor vulnerabilities, apply security patches as soon as they are available, and perform regular updates as part of our maintenance packages.
Can you add a specific feature to my site after delivery?
Absolutely. Whether it's a small adjustment or a major new feature, we can plan and implement custom enhancements according to your needs and our pricing grid for out-of-package requests.
What are the response times for a support request?
Times depend on the chosen maintenance package. They can range from a response within 48 hours for a standard package to a guaranteed response within a few hours for a premium package with SLA. Critical emergencies are treated with priority.
How can I measure the return on investment (ROI) of my new website?
We define key KPIs (traffic, conversions, sales, leads) together before launch. By integrating appropriate analytics tools, we provide you with regular reports allowing you to correlate site performance with your business objectives to evaluate ROI.
What is your approach to responsive design?
We use a 'mobile-first' approach, designing the experience for mobile screens first, then progressively adapting it to tablets and computers. This ensures an optimal, fast, and intuitive user experience on all devices.
