I have a unique situation...we sell about 700 unique products on our website, and I want to create an adwords campaign that uploads each product number with the current stock and price. They would all have the same ad, just different keywords. Is there a good way to accomplish this so that I could upload the changes weekly and keep the inventory/price current on adwords? I have a file with all of our inventory, just need to know how to format it and how upload it. Thanks!
