1. verify that the website is (still) both verified and claimed.
2. verify there is only one single feed file registered (per-country). the registered file name and uploaded file name must match exactly; a tab-delimited feed file name must end in .txt an xml-formatted feed file name must end in .xml
3. verify every item has a unique id value; an id must be unique per-item and should never change or be reused for a different item.
4. verify that multiple-target-countries are not using the same landing-page, the same feed-data, or the same id; landing-pages, feeds, and id's must be unique across countries.
5. verify the website that hosts the items is functional -- all link urls must be working during the entire time that any products are active, and google must not be blocked from crawling the website or items for policy inspections.
the price submitted, displayed, and default add-to-cart checkout price must all match exactly.
6. verify all items not physically in-stock have an availability value: out of stock
out of stock items may not be listed by google -- and may always show a status of searchable soon.
however, inaccurate availability can trigger a suspension.
7. verify accurate expiration_date values -- verify expiration_date values are not set in the future or set to expire before processing completes; otherwise, use the 30-day default and do not use expiration_date
8. for most items, verify at least two accurate and exact mpn, brand, and gtin global-trade values are submitted.
also, be certain that any global-trade values submitted have not be self-assigned or assigned to custom-packaged items; only submit global-trade data that currently exists.
apparel and clothing require only brand; media and software require only gtin.
all merchants should be using the same valid global-trade values for an item as assigned by a brand-manufacturer.
items without proper global-trade data must have an exemption. handmade, custom, or self-packaged items require an exemption;
9. verify every item has an exact image of the physical product; images cannot contain any promotional text or any watermarks.
10. verify the requirements against the type of item being sold, the registered feed's target-country, and for any variant items.
11. verify tax and shipping are set in the account; for non-us items be certain all vat and charges are included in the item's price attribute.
12. verify feed-status by clicking on the summary report under 'status': http://www.google.com/merchants/bulkuploads google may sometimes be confused about certain issues in a feed so not all issues that can be causing problems may be reported -- the report may also indicate specific feed issues or invalid items.
15. verify no 'I fixed all highlighted issues' buttons are seen within the account -- a few suspensions may trigger this button; all related issues must be fixed in the feed first and then this button must be clicked; the fixes may take 24-72 hours to process and resolve unless there is an additional penalty: http://www.google.com/support/merchants/bin/answer.py?answer=1678275
16. verify the number of items or size of the feed does not exceed google's limits.
17. verify the items, feed, and website against all requirements, rules, and policies, of the target-country; for example, some types of items are simply not allowed.
since improperly formatted feeds can cause processing to falsely read correct data; always view .txt feeds within a browser or notepad to check the saved data.
if a third-party or third-party software is being used to submit items -- such as a shopping-cart, inventory system, or web-hosting company -- then the third-party should be contacted directly to resolve or help resolve the issues.
