When adding a hotspot, Sauce places it in the middle of an image. More often than not, this is not where the product is! Or, there are many products to be tagged.
Fear not! It is super simple to move the hotspots around your image.
After you have added a hotspot with a product link to your image, click and hold the tag and drag it to the most relevant point.
This will means a specific product can be tagged and is super useful if there are multiple products within an image.
Take a peek at this guide for adding single or multiple hotspots.
