FAQs

We answer common questions about custom web design, online shops, maintenance, hosting and search visibility.

Why does website loading speed matter?

Speed affects ease of use and can influence enquiries or purchases. Google uses page experience signals, although a fast website does not guarantee higher rankings. Measure loading, responsiveness and visual stability on mobile and desktop. Avannubo optimises resources, images and code to improve each project’s performance.

Why should a business website be mobile-friendly?

A mobile-friendly website makes it easier to read content, navigate, complete forms and shop on small screens. Google uses the mobile version of content for indexing and ranking, so it must retain important information and functionality. Responsive design needs to be supported by real navigation, accessibility and performance testing.

Does a business website need HTTPS?

HTTPS protects the connection between browser and server using TLS, although it is still commonly marketed as an SSL certificate. It is a basic measure, especially when submitting forms, credentials or payments. It also helps avoid insecure-connection warnings. The certificate must remain valid and be supported by other measures: HTTPS alone does not guarantee that a website is trustworthy or secure.

What legal information does a business website need in Spain?

The required sections depend on the activity and data processing involved. A legal notice and privacy information are usually needed; if cookies or other technologies are used, their purposes must be explained and consent obtained where required. Non-exempt technologies need appropriate accept and reject options. An online shop must also include the relevant contractual terms and consumer information.

Is web accessibility mandatory for private businesses?

The obligation depends on the service and applicable regulations. Since 28 June 2025, Law 11/2023 has set requirements for certain services, such as consumer-facing ecommerce, with exceptions and transitional measures. Microenterprises providing services have a specific exemption under this framework. Each case must be checked: referring to WCAG AA does not by itself demonstrate legal compliance.

What is the difference between shared and managed hosting?

Shared hosting describes a service in which several websites use resources on the same server. Managed hosting describes the level of management the provider undertakes, such as updates, backups or monitoring. The categories are not mutually exclusive: shared hosting can also be managed. Compare resources, responsibilities, support and recovery terms.

What does website maintenance include?

It may include updates, backups, functional checks, security reviews and support. Content improvements, new development and response times depend on the contract. Maintenance reduces risks and helps keep the site operational, but does not eliminate every possibility of failure. Avannubo defines the scope according to the site’s technology and needs.

What should I do if my business website has been hacked?

Contact the technical lead to contain the incident and preserve evidence. Before restoring a backup, investigate the access route used, fix the cause and verify that the backup is valid. Credentials and related services must also be reviewed. If personal data has been breached, notification is determined by risk; where mandatory, it must be made without undue delay and, where possible, within 72 hours of becoming aware of it.

Which payment gateway is suitable for an online shop in Spain?

It depends on the customers, markets, ecommerce platform and commercial terms. Available options include banks’ virtual payment terminals, Stripe and PayPal; Bizum can be integrated through compatible providers. Review fees, refunds, subscriptions and authentication. Avannubo assesses compatibility to integrate suitable payment methods for each shop.

How much hosting storage does a business website need?

The space required depends on files, images, documents, databases and expected growth. Check whether email and backups use the same quota. A small website may need little space, but that does not determine its performance. Avannubo sizes hosting according to content, traffic and recovery requirements.
