You need not be a professional or possess exceptional writing skills to write a blog. However, in order to write an article for promoting your blog, you definitely need more skills.
Use the right language: One of the first & foremost things to consider in blogging is your language. While most people are under the impression that they can write very well, it doesn’t actually hold true. People usually fail to understand the ‘BIG’ difference between spoken & written English. While a not-so-good blog post with a worthy message for the users can work well for the bloggers, it doesn’t really work in case of articles. It is therefore better to seek the help of professional article writers or ghost writers to do the job for you.
Keep to 100%: It is not mandatory to make your article serious or to add humor to it. The mandatory part is to maintain either of the two to 100%. If you are not good at adding sensible humor to your article, then try to be 100% serious & be very accurate in your facts & figures. Remember that your article is meant to offer useful information to the user, so be authoritative in whichever topic you pick up.
Convey the right message: Your article is meant to advertise your blog. Thus, unless you can effectively convey the right message of your blog, it is of no use. Here again you may choose out of the two ways i.e. humor or serious to make your readers understand the message you wish to convey. The secret is to develop your article in a way that catches the attention of the reader & tempts him to come back for more.
Maintain a natural writing flow: Although following the rules & guidelines of article writing is an important factor to consider, it is always better to develop a natural flow of writing. This means that, to develop a good piece of article, try to write it from your heart & not your mind!
