When you first create a website, there is a dummy post, page and comment which have to be deleted, you have to delete them. This is the first time that you will have to delete a post.
To delete a post, in the Dashboard of WordPress go to Posts, and click All posts.
Put your mouse under the title of the post and it will appear a Trash link.
You can do the same thing with pages. Go to the page’s tab and click all pages. Then click Trash.
Using WordPress is one of the essential skills for an internet marketer. I have been learning these skills and a lot more others in an online program which is called Wealthy Affiliate. You can achieve expert level with this program and also build a successful online business and make a lot of money with it, you can see proof of this in my Wealthy Affiliate review. I hope this helps.
