Due to recent change to item and feed limits, you may experience errors when submitting your items or registering a new feed.
To check whether your new feed is affected by our new item limit, navigate to the Data Feeds tab and click on “x of x items inserted (view errors and warnings)” to the right of the newly registered data feed. You may also receive an error when registering a new feed if you reach your feed limit. You can request an item and feed limit increase by contacting us through our Help Center.
Important: Existing feeds that have been registered before 11/22 will not be affected, but only feeds that were registered in the Merchant Center after 11/22. When you update your existing feeds, make sure to not delete the existing feed but simply initiate an upload under the already registered feed to prevent your existing feed from becoming subject to the temporary limit. You can do so by choosing an upload method right next to the data feed name under Data Feeds>Upload and follow the instructions as usual.
Google recommends that data feeds be under 20MB for upload within Google Merchant Center, while scheduled fetch and FTP uploaded feeds can be up to 1GB. Compressed feeds must be under 500MB or you will need to split them in to 500MB or less files.
While most will not be affected by this, I think new feeds will come under deeper scrutiny with regard to size, data quality, freshness and so on.
