Obtaining a domain name and hosting space

A website needs to have a “address” and a “home” on the internet. The domain name is the address where your website can be found, while the hosting space is the place where all the website’s files and data are stored. It is recommended to choose a reputable domain name registrar and hosting service provider.

A professional website should not only have an attractive appearance but also a clear structure and high-quality content. The core functions of WordPress revolve around content and user interaction.

Create pages and articles.

Manage the navigation menu

The navigation menu is the roadmap of a website. Go to “Appearance” > “Menus” to create a new menu. You can add items from the pages, articles, category directories, or even custom links on the left side, and arrange their order by dragging and dropping them. After creation, you need to specify where the menu will be displayed (for example, “Main Navigation”), depending on the menu placement options supported by your theme.

For example, if you need a contact form, you can search for “Contact Form 7” or “WPForms.” After installing and activating the plugin, new settings options will usually be added to the backend menu. Make sure to obtain plugins from the official repository or trusted sources, and always keep them up to date.

Advanced customization and performance optimization

Once you have mastered the basic operations, you can create a unique website through advanced customization and ensure its speed and security by implementing optimization measures.

}

How to choose a WordPress theme that suits you?

When choosing a theme, the following aspects should be given priority: responsive design (compatibility with phones and tablets), loading speed, compatibility with popular plugins, the frequency of updates by the developer, and user reviews. It is recommended to start with free, official library themes and only consider more advanced themes after you become familiar with them. Before installing a theme, you can check the theme’s demo site and documentation.

How many plugins are appropriate to install on a website?

Only install plugins that are truly necessary, have good reviews, and are frequently updated. Regularly check your system and disable or remove any plugins that are no longer in use.

How to back up a WordPress website in the safest way?

The safest backup strategy is to perform regular backups in multiple locations. It is recommended to use a reliable backup plugin (such as UpdraftPlus) to back up all website files and data to remote locations, such as Google Drive, Dropbox, or an FTP server. Set up an automatic backup schedule (for example, a full backup once a week), and also create a manual backup before making any major updates (such as upgrading the WordPress core or changing the theme).
