i currently cannot have my watches on google product search it requires age,gender and color
until now i was using the xml feed from ez it doesn't have this feature
Can i add in the cs-cart a field for age gender and color and then create a feed from it?
Contact Google and get an exception since they don't apply. Age, Gender and Color are only mandatory for US merchants where the category is an Apparel category. If you've listed your watches as Apparel then that's why they're being required.
Google has really lost a lot of credibility with the required attributes for Apparel. It will fade, but in the interim there are ways around it.
Contact me if you really want these fields. You can beta test a version that has them. But note that you'll also need unique images for every option combination to comply with Google's requirements.
