how to write article?

Articles are easy to write as long as you have the communication skills to do so. Earning money from article writing usually involves some SEO knowledge since most people looking for writers have keywords they need articles written on. There is a wealth of information online about SEO and content creation, you just have to look for it. Information about article marketing will be pretty helpful in learning about how articles play a role in SEO. To actually earn any money doing this, you will likely want to start at some of the "content mills" that exist. This is how many writers have gotten started into the business and it can be used as a learning process when breaking into the industry. Sites like Text Brokers are commonly used by new writers, but you need to posses a decent level of English skills in order to have any success there.

The best I've seen for an explanation for how to write a good article was from Helium.com under their help section. They are an article writing site and have many useful tips for how to write well. Also it is a community of writers so you don't have to be shy when it comes to asking questions. They are all really nice and everyone is trying to write better.
