Analyze your audience
No matter what you are writing — an article or a sales letter — you should first analyze your audience or those whom you are writing that information for. If you have been writing for your target audience for long, you can use the past experience and write content keeping in mind their behavior and taste.
Writing for permanent customers is not something that should worry you as you can get away with flaws and repetition of content, but new prospective clients should be taken seriously.
Never underestimate the power of headlines
Catchy, informative and concise headlines usually work wonders. But you may be one of those who have been underestimating this powerful tool. If you have to write content for online publications, websites or blog, attention-grabbing headlines can engage the readers and they are usually compelled to read more.
Tell the main point at the start of content
State your main objective/points in the first paragraph, as online readers usually skim through the pages — they do not read the whole article that runs for several pages.
Remember, your reader is constantly looking for informative content, so not telling them your main case and point of content in the initial paragraph will turn them off and they might go to other websites.
Use simple language
Use simple structure of language, as nobody will read your content to see how good a writer you are — they will read the content in order to learn and gain something. So do not try to sound like Shakespeare, unless you are writing content related to English literature.
Proof read and edit
Do not forget to proofread and even edit your content before it leaves your hands.
