Link/Resync Merchant Feed to Optmyzr
Before you can use any of the Shopping tools for the first time, you'll have to link the Merchant Center Login email and then the individual product feed (Merchant Child Account).
After linking the Merchant Center Login email, enter the Merchant Account ID (product feed id) to link that specific feed.
You can link the Merchant Account and Product Feed on the Manage Merchant Feeds page.
We recommend you always re-sync your feed with Optmyzr whenever using any of these tools, as using an old feed may turn to inconsistent results.
