While you want your content to be informational, you don’t want to imitate a text book or some thing that will bore people who may possibly buy Twitter followers at this point of time. There are many ways in which you can provide valuable information that people need and are looking for without sounding ‘clinical’ or ‘academic’.
There are some who believe that if you don’t catch someone’s attention in the first few seconds you will lose them. So you want to use strong, exciting words, especially in your subject or title to grab the reader’s attention. If you apply this concept in tandem with search engine optimization where you should use your keywords* in the title or subject this should work together nicely. *(and use keywords sparingly in the article, 1-3 times max – if you overdo it you will have the opposite effect that you intend on every level). Don’t be a keyword spammer.
So you want to attract the reader and then hold their attention until you get your point across. This is done via the title and through something that is sometimes referred to as ’emotional writing’. Emotional writing can also be seen as dramatic or compelling. In advertising and sales, there are many ways in which this works, from using time constraints, ‘last chance’, ‘don’t miss it’; Scarcity, ‘last 5’ the ‘next 8 callers only’; Compelling words – ‘must have’, ‘secret tips’, ‘top of the line’, ‘unbeatable’, ‘latest discovery’; to words that mean totally great, the best, fantastic, wonderful, amazing (and words we all know and over-use (so don’t) like ‘awesome’ and ‘absolutely’).
