It’s not always an easy thing to write an article or a post but it is considered as a great method to get customers if you have a website or a blog.
On the other hand, there are other people who like to write for the pleasure of it in order to share their knowledge and expertise with others.
There are different formats of how someone can write an article: Survey Results, How To's, Pros and Cons, Lists and Answering a Question are just a few of the known formats. It goes without saying that all formats have rules required by publishers; however the length of the article may vary between publishers, so make sure that you find out what the rules are and adhere to them.
I may be of great help before you get started to write down a list of topics which all relate to your subject.
An important part of the article / post is its title, so make sure you remember that this is the first item that is read; it has to be catchy, to the point and the article must then be on what the title says. The last thing you want is to mislead your readers.
