Articles are a way to engage your readers long enough to feel like you have got your point across and have held your readers attention long enough so they actually look to the bottom and see who the author is, thus giving you recognition for your expertise.
The suggested ideal length for internet readers is 250 – 1000 words. If you go over this you may want to use sub headings to make it easier on the eye or break it up into a few different articles. Keeping to these tips will increase the chances of you being heard, understood and recognised.
