I have an online shopping site that a few people have written reviews on their websites about some of the products I sell. Should I put on the product page a link to their review for these reasons 1) help people decide whether they want to purchase the item, from reading a review and 2) encourage more bloggers and web owners to review my products and link to me? and 3) they link to me and drive referral traffic to my website. Is it a good idea for me to give them a link? Thanks in advance.
