Not unless it is really good content, but that's besides the point. I would suggest contacting webmasters of people who have done reviews of niche related products. Chances are your item hasn't been heard of yet. One of my better selling CB products took about 6 months to really take off and the first 3 months were really just minor hits and sales.

Also, don't neglect the affiliate section. This is extremely important actually. Myself, I don't even bother promoting a site unless there is a pre-written email for me to copy and paste, otherwise, i just move on to the next competetor who has it.

Some of the highest gravity sites also have amazing affiliate sections.

Also try and include some articles for them to post. And run your articles through a spinner so that the aff's can have some unique content to play with. Trust me - it works.

Finally - do you have an opt in form? You need to send out at least 1 email every day for 3 days reminding the customer of the product. Hardly anyone buys up front unless the product has already been reviewed on a niche related forum.
