WordPress Basics
WordPress enables website owners to update page content and operate a blog page through a friendly interface (avoiding the need to learn web design skills).
Before beginning, it’s really important to understand the difference between pages and posts.
Your website will consist of any number of web pages containing updatable content. One of the pages is the blog page (unless you’ve chosen not to run a blog/news page). The blog page can sometimes be set as the home page or it might be a completely separate page called News, instead of Blog.
WordPress Fundamentals
Posts
The blog page of your website automatically lists individual posts added by yourself. These can be of any length – short punchy updates or incredibly long features or stories. It’s your choice…
Posts are often dated marked (and sometimes the post author is displayed also). Usually, they appear in reverse chronological order; as you publish new posts, older posts get pushed down the page. If you’re blogging a lot, it can help users if you categorize your posts. Speak to your designer about this.
Your design will determine how many posts are listed on your blog page. If you’re showing too few or too many posts, there’s a simple setting to control this in the admin area. You might need to ask your web designer to change this for you.
Once a post drops off the bottom of the page, it can still be accessed using other methods (e.g. ‘Older Posts’ links and Archive pages). And remember that each post can be individually indexed by search engines (treated as a single web page); users may arrive at your post directly, via a search engine.
Pages
Pages are more permanent. Typical examples would be your Home page, About us, Contact us, etc. Here’s a good explanation from WordPress.com:
Once you publish them, they stay put. They’re handy for timeless content, like an About or Contact Me section. This stuff probably isn’t going to change very often, and you want your visitors to be able to access it easily no matter where they are on your site. Your pages are displayed in a menu somewhere on your blog that’s always visible (usually up near your header or in a sidebar), so people can explore your site with ease.
Before updating your website, be clear in your mind about the task you wish to perform. Are you updating a page or a post?
