So when Google announced that they would let shops upload their products to Google Shopping for free, I thought this would be a good opportunity to try out Google Shopping and maybe start advertising. Spent a ton of time getting things formatted correctly, linking accounts, meeting requirements, etc. My products are all approved and active on Google Shopping and "partially active" on Surfaces on Google. Not a single one of them turns up in incognito browser session of Google Shopping even with a very specific string of search words that only returns a page or two of results. There are no errors or issues with my products according to Google Merchant. I am set up to appear in US. Shipping settings set. Everything seems to be in order but why is nothing showing up in search? (specifically Google Shopping, some of my things and store show up in general Google search and image search but it almost seems like LESS than before I set up Google Merchant and did all of this other stuff)
I contacted Google Merchant support and their response was like, "Nope, your things are fine and all active."
To be eligible for showing listing in Google Shopping Free Listings, you need to have enhanced listings approved. From your reply you seem to say you are partially active, so this is the reason.
Make sure you follow the requirements here: https://support.google.com/merchants/answer/9199328
Even then if you follow the requirements, if your account says not eligible, then you can't show your ads.
The most common reason is if you are drop shipping (not stocking goods), which is not allowed on Google Shopping.
