Writing an article is really not that hard, you just need a few important ingredients.
It really is that simple, however for some writing can be a difficult thing, mostly because people talk differently in different regions.
Which is why you want to avoid as much slang as you can unless you know your target audience is into that language then you can engage in it.
First you need a topic and for the most part in article writing, there are just a few different methods, (actually there are several) but the most important aspect of article writing is to write with a combination of the two most popular methods.
Keywords and readability.
Keywords are words that are commonly used by searchers online to find information fast, they use these words when they are looking for certain types of information and they expect to get the information they want.
Readability, this is really self explanatory mostly because what your writing should be easily absorbed and understood by the reader.
However we mention it now simply because a lot of what passes for articles today is not really human readable.
So, read the stuff you write and edit it make it better generate better fodder for the mill and the world will beat a path to your door.
