1.
Practice.
Just like any other endeavor, article writing is something that you'll be able to master overtime through constant practice.
That is why, I recommend that you make time to write your articles on a regular basis so you can easily get the hang of it.
2.
Ask for feedback.
The best way to know if your articles are really great or if they need improvement is to ask for the opinion of other people.
What you can do is show your copies to friends or better yet, to people who are considered writing gurus.
Take each feedback constructively and find ways on how you can convert your weaknesses to strengths.
3.
Seminars and trainings.
You'll be happy to know that there are now a lot of trainings and writing seminars that you can take advantage of for free.
All you need is time and the willingness to learn.
In here, you'll be able to obtain indispensable tips and techniques that will make you a better writer.
4.
Improve your vocabulary.
As a writer, it's important that always expand your vocabulary.
People are most likely to pay attention to you if you can effectively get your message across using the most appropriate words.
I suggest that you check your dictionary everyday and try to learn a word or two.
5.
Mind your grammar.
Here's the truth; your readers will not possibly take you seriously, no matter how informative and useful your articles are, if you grammar isn't simply right.
You can't expect these people to do business with you if you say something like "do not advertisements your products", right?
