There have been a couple discussions on one of the reviewers forums I thought should come over here.
1) Bad Codes. They are rampant. I know that personally last week 50% of the codes I received were bad. The real shame is that at least two of the items were things that I actually really wanted (most of the things we get off here as reviewers are "this might be cool" type requests or "I'm trying to raise my rank so I'll play this game with you because I think we both know I'm not a Duggar and I don't need 15 phone cases" type of items) and as sellers you should really want to put things into our hands in those situations since you then know we are going to put more into our review of the product. We know that the codes are not your fault but when we take the time to email you and let you know there is an issue... you should probably reply. Just another reason you really should read your emails.
2) Ridiculously low discounts. As a seller, you are probably going to hate me for saying this but.... As reviewers, we don't actually NEED your product. Nobody actually NEEDS a silicon spoon rest or a pair of yoga pants that won't be delivered for 2 months, or an egg storage tray and even if they did, no one actually believes that the egg storage tray should cost $30. We come here because it's fun to get a bargain even if you don't need the item or because our delivery guy is hot and we like seeing him 4 times a week or we are just bored. You on the other hand are paying to be here because you need some help lighting the burners under your sales, and to have access to us amazing, enlightened, articulate and exceedingly special people (only half joking). You are even paying for the pleasure of our company (lets not go there). You need us to be willing to pay a couple bucks to try your product out and then put some effort into the review in return for you sacrificing early profit for the long term win. So with that in mind, 20% and 30% discounts are just wasting your time and ours. You have to list them here and keep checking back to see about requests and then try to figure out why there are none and we have to actually sift through all of those listings to get to ones where the discount on the item equals the value we have put on the time we will spend writing you a productive review. Stop the madness! Bite the bullet and make it a game we want to play with you. A report came out yesterday showing that consumers are already starting their Christmas shopping. We are ready to help you get your product into their view but you have to Help us to Help you.
Oh, and pay attention to who you are giving codes out to. Believe me, as reviewers, the two sentence reviews where one is the disclaimer and the other is either "this sucked" or "this is awesome" are as frustrating and embarrassing to us as they are to you. They make us all look bad but you can stop perpetuating them if you start reading a couple of the prior reviews of people applying. You are making an investment in them. You have to do a little research. I've noticed a few sellers asking on here how to make members leave reviews... knowing who your are giving the codes out to is probably the best way to do that. If you are paying attention to the person you send codes to and you are still not getting reviews you might want to send them an email and ask in a more personal, less form letter type of way if there was some type of problem with the product that you might be able to address since a lot of the hard core reviewers will choose to leave no review of an item that they don't feel they can honestly leave a positive review for.
Good luck and have a great day!
