Non biased reviews based off of your own industry research. - Articles/Reviews has to be of top quality and with the length of min 2000 words. - Good presentation is very important. - You should break it up reviews into sections: description, pros and cons, comparison and conclusion. - No over use any particular word. Variation is good. - For example, If this is a review for a particular tv, say: samsung 345 ZT. Throughout the article when you refer to the product, have it mix it up, for instance: the samsung 345 zt, samsung 345, this samsung hdtv, etc... - 'Lightly' use the keyword throughout the remaining article.
