I'd like to know why ASIN searches are not working for me. I keep getting errors.
ASIN did Not Return any Results, Credits were not Used
Please Check that this ASIN shows up in an Amazon Search (Click Here to Verify on Amazon)
This usually happens when you are trying to do an ASIN search on a product that isn't very popular. While it may be your competitor, it doesn't mean that it's a product that people are actually buying.
Make sure that when you are doing an ASIN search that you pick an ASIN that's selling well (like a best seller in your category). If you do a search on a product that is a best seller in your category you should be okay.
