WordPress content updates can seem like a daunting task if you’ve not done them before. The first thing to realise is that in WordPress content is split into 2 types; Posts and Pages. Generally speaking, you would update the Pages to change the layout and content of your website, and update the Posts to add to the blog or news section.
There are, of course, instances where you would update a specific type of post to update a section of a page on your website. These are called custom posts.
You update your content by going to the admin area of your website this is generally located at www.yourdomain.com/wp-admin/ from here you will be able to login with your username and password.
