All of our sponsored posts are created and managed through the same Facebook account - BookBaby Bookshop (https://www.facebook.com/BookBabyBookShop/). This does mean those who click on the ad will be taken to your Bookshop page. After the ad is clicked, customers will be taken to the landing page of your choosing, as noted in your proof.
The Bookshop account has no influence over your landing page. Please just be sure to include the correct site or URL for our team to use when creating your campaign.
