Review sites are a real challenge now.
A problem that others have had is that they review products that they've never used and simply copied the details from the Amazon listing.
Instead, you need to show that you actually know about the product. What do you like about it? As well as what you didn't like, and how you felt about using the item overall.
I've read so many review site pages from those that have allegedly tested the products and they read like shit.
Today I knocked back a supplier who wanted me to review one of their items.
The reason for the rejection is that they don't ship outside of the US and I'm in the UK so there's no way for me to write a proper review about it.
It sounds harsh, but it's a good thing that these review sites are harder to rank now, it means that the buyer isn't going to get short changed on a garbage product.
