What is WordPress?

WordPress is the world’s most popular content management system (CMS), powering over 40% of all websites. It’s open‑source, free to use, and highly flexible.

Why WordPress is Popular

• Easy to use: No coding required for basic websites.
• Customizable: Thousands of themes and plugins.
• SEO‑friendly: Clean code and built‑in SEO features.
• Scalable: Works for small blogs to large e‑commerce sites.
• Community: Massive support and resources.

Types: WordPress.com vs WordPress.org

• WordPress.org (self‑hosted): You own the site, install your own plugins, and have full control. Recommended for serious websites.
• WordPress.com (hosted): A hosted version with limitations (free plan has ads, no custom plugins). Good for beginners but less flexible.

Websites You Can Build with WordPress

• Blogs
• Business websites
• E‑commerce stores (WooCommerce)
• Portfolios
• Membership sites
• Forums and social networks

WordPress Ecosystem Overview

The WordPress ecosystem includes themes, plugins, hosting providers, and a large community of developers and users. The official repository (wordpress.org) offers thousands of free resources.

What is a Domain Name?

A domain name is your website’s address on the internet (e.g., example.com). It should be memorable and reflect your brand.

Choosing an SEO‑Friendly Domain

• Keep it short and easy to spell.
• Include a keyword if possible.
• Avoid hyphens and numbers.
• Use .com when available.

What is Web Hosting?

Hosting stores your website files and makes them accessible online. It’s like renting space on a server.

Types (Shared, VPS, Cloud)

• Shared: Cheapest, resources shared with other sites – good for beginners.
• VPS: Virtual private server – more resources and control.
• Cloud: Scalable, pay‑as‑you‑go – ideal for growing sites.

Buying Hosting from Hostinger / Bluehost

Popular hosts offer one‑click WordPress installation. Choose a plan, register your domain (often free for the first year), and complete the purchase.

Connecting Domain with Hosting

If your domain is registered elsewhere, update the nameservers to point to your hosting provider. Your host will provide the nameserver addresses.

Installing SSL Certificate

SSL (Secure Sockets Layer) encrypts data between your site and visitors. Most hosts provide free SSL via Let’s Encrypt. Enable it to use HTTPS.

One‑Click Installation

Most hosting providers offer a one‑click installer (e.g., Softaculous). Log into your hosting account, find WordPress, and click install. Choose your domain and fill in site details.

Manual Installation (Advanced)

Download the latest WordPress zip from wordpress.org, upload it to your server via FTP, create a database, and run the installation script. Only recommended for advanced users.

Logging into Dashboard (/wp-admin)

After installation, access your dashboard at yourdomain.com/wp-admin using the username and password you set.

Initial Settings Setup

• Delete the default “Hello World” post and sample page.

Dashboard Interface

The dashboard is your admin area. It includes a toolbar, welcome panel, and quick links to common tasks.

Posts vs Pages

• Posts: Dynamic content, organized by categories and tags, displayed in reverse chronological order (blog).
