Keywords: Omega uses + and - as it's keyword format. These are separated by commas with no spaces. Example: +nike,+sacai,+blazer,-waffle

Product URL: With early links & product links all you have to do is paste the link in the "Product" section, do not use + or - as you would for keywords.
Example:
https://kith.com/collections/mens-footwear-sneakers/products/nike-blazer-mid-77-vintage-white-black

Variants: If you are using a variant just paste it into the "Product" section, do not use + or - as you would for keywords. Example: 31954431246411
