In order to attract customers the articles on your website must offer something new and attractive. What readers really want to know is if what they're reading can make a difference to them and be of benefit to them, they're not interested in reading what happened to so and so, they want to know if it can be useful to them. Even more important is to make things easy for them, suggest that what you're offering is simple to apply with no hidden surprises. You will have to target your potential customers, try and persuade them that what you offer is what they always wanted!
The length of your articles is important, write content of about 500 to 600 words, no more no less. If you need more words to get your message through, then you are probably just repeating yourself and most of all you are becoming a bore! You may also like to consider splitting the content into two articles, this will increase the chances that both articles will be read.
When choosing your copy write content avoid alienation, that is do not in any way offend your potential customer with sexist remarks, for example or racial comments or even sophisticated language, which may estrange the reader and make him feel inferior to you. Always treat your readers with respect, offer the best information for them, make them feel exclusive and catered for.
Affiliate links are useful too, as they provide additional information about the service or product you are proposing, but they must not be used to substitute any useful information you can give in your article. You are the one who should provide clear and useful content, do not refer your reader to someone else. You may prefer using embed links, which can provide additional reading material if the reader wishes, he or she must not be obliged to go and find the information somewhere else. Your aim is to get readers to read on and not move forward to another more engaging website.
