Writing a high quality article ensures that wherever it ends up it will be well received. Here are some tips to make sure you are writing a high quality article that people can enjoy reading.
Read it out loud when you are done. This may seem silly, but reading something you have written silently may not reveal mistakes. If you speak it aloud you will easily be able to catch certain mistakes that you may not have seen. It will flow easier and sometimes you may find you write things the way you yourself may speak them. Out loud you can make sure the tone is one that all people will enjoy reading.
Have someone else read it before submitting it. Having a second pair of eyes review your work double checks any discrepancies you may have found. Do not ask them for their opinion. That may skew your own view on what it is you are trying to convey. Simply ask them to look for errors, or if a sentence sounds as odd to them as it did to you.
Write multiple drafts. This tip is if you get stuck with whatever it is you happen to be writing about. Sometimes it happens, and the frustration you feel at not being able to put anything down can make your writing sloppy and ill suited for people to read. Especially if you are writing free articles, they may get overlooked due to a lack of drive. Writing a few different drafts can sometimes help you find direction.
Brainstorm catchy ideas with other article writers. Sometimes two heads, or even more, can help you to come up with ideas if you are struggling to write. Having a get together with fellow writers is an excellent way to conjure up creative ways to write high quality articles.
Try freelancing for a while. Free custom articles can help to give you a break from your normal work. Freelancing is a way to let your writing relax a little bit. Keeping yourself wound up by writing strictly professional articles can sometimes lead to a lack of motivation and creativity. At least this way you are still writing, but at the same time letting yourself be innovative with it.
