Although WordPress was originally a blogging CMS, it is now used to build corporate websites and
e-commerce stores. You can either use www.wordpress.com to build a free blog where you can get
free hosting and a blog name or you can install WordPress on your own server by following the steps
outlined in this link: .

Installing WordPress requires
that you know how to set up domain names and servers. Each WordPress website has an admin page
where you can add content, change the website layout, or add features and functions. WordPress is
based on the PHP (Hypertext Processor) programming language that is used to create dynamic web pages.
Understanding WordPress CMS

WordPress Themes
The website or blog design in WordPress depends on themes. These are groups of images, PHP files, and CSS (Cascading Style Sheets) files used to create the graphical style for the website menus, forms, and other features. You can upload the themes to the server in the folder /wp-content/themes/. To apply the uploaded theme, you activate it from the Themes section in the WordPress admin page. The layout of the website or blog plays an important role in SEO optimization; it has to be clear and ensure that the content loads easily. It can be difficult for search engine spiders to crawl large files. Further, the layout should be user friendly, display the content in the top portion of the page, and have balance between text and images. A wide variety of WordPress themes are available on the web for free as well as for a fee. You can find free themes in the WordPress Directory
WordPress Plugins
WordPress plugins are a group of PHP-based files that add features and functions to WordPress websites or blogs. Unlike themes, plugins include functions such as contact forms, social media buttons, and more. Different types of plugins can optimize your WordPress website with just a few clicks. There are two methods for installing plugins. The first one is to search for the plugin and install it directly from the Plugins section on the admin page, and the second one is to upload the plugin folder to /wp-content/ themes/ on the WordPress website server, and enable the plugins from the admin page. Use plugins wisely because they include a lot of code, which can make a site slower than normal. You can find a huge number of plugins in WordPress Plugin Directory
