Hi We wanna create a few landing sites for our main e-commerce site. We just want to use them at the platform pinterest.com. One site for one pinterest account. But if we let the google to index our landing sites, that would let google think we intentionally make the backlinks to our main site? When the customers click the "Go to buy" button under the product from our landing sites, they would be redirected to our main e-commerce site for purchase.
