DELUXE WIKI ✦
Complex ideas. Clear answers.
Websites, servers, security and AI in plain language, with practical guidance.
Websites
Landing page
A single-page website for one service, product or campaign. It explains the offer and guides visitors towards an enquiry. Timing depends on scope and available content.
Read →CMS
A content management system lets your team edit pages, products and content without a developer. The CMS, themes and extensions need regular maintenance and updates.
Read →Responsive layout
A layout that adapts content and controls to the screen width, keeping a website readable and usable on phones, tablets and computers.
Read →SEO foundation
The technical groundwork that helps search engines discover and understand a website: clear pages, useful headings, metadata, a sitemap, structured data, fast loading and HTTPS.
Read →Redesign
An update to a website’s appearance, structure and visitor experience. Useful content and existing URLs should be reviewed, with redirects prepared for changed addresses.
Read →Updates
CMS update
Bringing the CMS, theme and extensions to compatible, supported versions. We test on a copy before changing the live site, with a backup and rollback plan. WordPress and similar CMS updates start at RUB 9,000.
Read →PHP 8
The server-side language used by many CMS platforms. A supported PHP branch and compatible extensions matter more than the major version number alone. Migrations should be tested on a copy.
Read →Core Web Vitals
Measures of real visitor experience: loading of the main content (LCP), response to interactions (INP) and unexpected layout shifts (CLS). They help identify problems that make a website difficult to use.
Read →Website migration
Moving a website to different hosting, a server, a domain or a CMS. A careful migration includes a backup, testing, data synchronisation and a switching plan, with redirects where needed.
Read →Servers
VPS & dedicated server
A VPS is an isolated virtual server with allocated resources; a dedicated server gives one customer the whole physical machine. The choice depends on load, software, data requirements and budget.
Read →HTTP/2 & HTTP/3
Versions of the protocol used to load web pages. HTTP/2 multiplexes requests; HTTP/3 uses QUIC and can handle packet loss and network changes better. Compatibility and network support still matter.
Read →Monitoring
Automatic checks of availability, errors, disk space, certificate expiry and other agreed indicators. Alerts help a responsible person investigate problems promptly.
Read →Backup
A restorable copy of website files, the database and necessary settings. Keep several versions, including one away from the main server, and test restoration regularly.
Read →Security
Vulnerability
A weakness in software, permissions or configuration that can allow unauthorised access or changes. An assessment identifies the cause and the update, code fix or setting needed to address it.
Read →Website malware
Malicious code added to a compromised website, such as unwanted redirects, spam tools, miners or phishing pages. Visible symptoms vary, so a clean-looking page does not prove the site is safe.
Read →WAF
A web application firewall filters requests using rules that can block common attack patterns. It adds a layer of protection but does not replace secure code, updates or access controls.
Read →Two-factor authentication
An additional identity check alongside a password. It reduces account-takeover risk; security keys and passkeys offer stronger resistance to phishing than codes entered manually.
Read →SSL · HTTPS
SSL certificate
A certificate links a domain to the server’s public key and supports encrypted HTTPS connections using TLS. It protects data in transit, without guaranteeing the safety of the website’s code or content.
Read →HTTPS
HTTP secured with TLS to protect data between the browser and server. It is essential for forms, sign-in and payments; server-side data security remains a separate responsibility.
Read →“Not secure”
A browser warning about an insecure connection or a certificate problem. The page address and exact error identify the cause. Avoid submitting passwords or payment details until it is checked.
Read →Let’s Encrypt
A certificate authority that provides free domain-validated certificates. An ACME client automates issuance and renewal, but that automation still needs maintenance and expiry checks.
Read →TLS 1.3
A version of the protocol that protects HTTPS connections. It reduces handshake overhead and removes obsolete cryptographic options. Certificate installation and protocol configuration are related but separate tasks.
Read →AI & bots
Knowledge-base chatbot
A chatbot that uses your approved service information, prices, terms and FAQs. It can rely on prepared answers without AI and pass questions outside its scope to a person with the conversation context.
Read →LLM — language model
A model that interprets and generates text, including answers and drafts. It can make confident mistakes, so company facts need approved sources, clear boundaries and a route to human review.
Read →RAG
Retrieval-augmented generation finds relevant passages in a knowledge base before a language model answers. It helps ground replies in company information, while still requiring source and accuracy checks.
Read →AI agent
An AI system with approved tools for defined tasks, such as preparing a CRM record or checking an order status. Permissions, spending limits, action logs and human oversight should be agreed in advance.
