-
WordPress
- The most widely used content management system worldwide. Open source, runs on your server, you keep control over everything.
-
CMS
- Content Management System. It lets people manage content such as copy, images and posts without editing program code for every change. WordPress is a CMS.
-
API
- Application Programming Interface. A defined set of rules that lets two systems exchange data or functions without exposing their internal implementation.
-
SaaS
- Software as a Service. The application is used through a browser or the internet instead of being installed separately on every device. Hosting and billing depend on the product model.
-
MVP
- Minimum Viable Product. A deliberately limited but usable first product version for testing the most important workflow under real conditions.
-
WooCommerce
- Shop plugin for WordPress. Turns your site into an online shop. Open source, no rental model.
-
Headless CMS
- Backend separated from frontend. Content in one system, presentation in another. Faster and more flexible, but more setup effort.
-
Custom Theme
- A custom-built WordPress theme. No marketplace template. Leaner, faster, tailored exactly to your site.
-
Page Builder
- A visual drag-and-drop editor added as a plugin. Convenient for layouts, but usually slow and hard to maintain.
-
Responsive Design
- Layout adapts to screen size. Phone, tablet, desktop, every device gets a sensible version. Standard since 2015.
-
Core Web Vitals
- Three user-centred metrics for loading experience, responsiveness and visual stability: LCP, INP and CLS. They help make real usability problems measurable.
-
LCP
- Largest Contentful Paint. It measures when the largest visible image, video or text block in the initial viewport has rendered, reflecting perceived loading speed.
-
INP
- Interaction to Next Paint. It measures how quickly a page visibly responds to clicks, taps and keyboard input during a visit.
-
CLS
- Cumulative Layout Shift. It measures unexpected layout movement, such as copy or buttons suddenly shifting while a page loads.
-
FCP
- First Contentful Paint. It measures when the first visible content is rendered. FCP is a useful loading metric but is not one of the three Core Web Vitals.
-
Schema.org / Structured Data
- Machine-readable metadata in the source code (usually as JSON-LD). Tells Google and AI engines: "this is a person, this a company, this a price." Foundation for rich snippets and AI citations.
-
JSON-LD
- A machine-readable data format commonly used for structured data. It can describe organisations, people, offers or FAQs alongside the visible content.
-
Hosting
- The server your site runs on. Monthly rental. Affects speed, uptime and data protection (server location).
-
Domain
- Your internet address (e.g. medienmacher.biz). Yearly rental. Should be registered in your name, not your web designer's.
-
DNS
- The internet's address book. Translates "medienmacher.biz" into the server's IP number. Whoever manages DNS controls where your domain points.
-
Cache
- A stored copy of a page. Faster because it does not get rebuilt every time. Can be annoying when changes do not show up immediately (clear cache).
-
CDN
- Content Delivery Network. A server network that puts content closer to visitors. From Linz, the site loads from Frankfurt instead of Texas.
-
Backend
- Everything behind the scenes. Database, logic, admin area. Visitors do not see it directly.
-
Frontend
- What the visitor sees in the browser: HTML, CSS, JavaScript.
-
HTTPS / SSL
- Encrypted connection between browser and server. Shown by the padlock in the address bar. Mandatory for any serious web project.
-
Tracking Pixel
- Invisible image or script that tracks who visited your site. Meta Pixel, Google Tag. GDPR-relevant, so not without consent.
-
Open Graph
- Meta tags that define how your page looks when shared on Facebook, LinkedIn or WhatsApp. Image, title, description.
-
Sitemap
- A directory of all your pages as an XML file. Helps Google find everything. Lives at sitemap.xml.
