Hi, I have a problem with some strange backlinks for some products in my shop. Today I checked the top refering pages in my search console and found a lot of products with strange backlinks. When I click on these backlinks it always shows me pages like "you won a iphone, a s9 ..." with a lot of popups. Here a picture from some of these links: https://www.bilder-upload.eu/bild-1b2950-1581417200.jpg.html Now I have some questions; * Why someone place a backlink like this for my products? * Affect these links my overall rankings? * What should I do against these links? Disavow? Thank you in advance for your help.
