Finally, try to keep your language mainstream and keep your VidInvision review page easy to understand. Now I'm from England, and sometimes have a problem with this. I remember writing the sentence 'It works a treat' in one of my sales letters, meaning that the method I was explaining works well. It seems that this turned out to be a problem, as one of my good friends from over in the US totally misunderstood what I was saying, and a slightly different meaning of this popped into his head.
So whilst you're writing, remember to keep things fact based, very structured, professional, and insert your own personality in there a little, without using slang words, or things that people from abroad might misunderstand, or even worse, just not understand at all. And the same should be applied to your VidInvision bonus package as well.
Rule number nine. Selling your products isn't the only thing you're doing inside info products, don't forget to sell yourself. Let your readers know who you are, where you've been, what you've seen or experienced, because in the long run, not only will they have much more belief in your work, but they'll elevate you in their minds and consider you a more trustworthy and a reliable source, and I don't need to tell you how important that is.
So there we have it. Eight basic rules that you can follow when writing your info products, ranging from increasing your reputation and how much people trust you, to actually getting people reading and taking action and talking about your product, how not to annoy the heck out of your customers and plug yourself effectively.
That's all I can do. Give you the basic rules to follow, and let you follow them. I would love to give you more, but I can't do that, simply because I have no idea what you're going to be writing about, I have no idea what your product is, and I have no idea about your writing style or your personality.
