I have a client that has 4400 products and it turns out that each product sells a few times a year. Is there any software that makes setting up say, 3600 ad groups fast and easy? I was thinking of using sqlite and adwords editor?
How do you generate your 10K+ ad text? The total product number is 147,000. I'm doing this small group for the initial test.
The last time I was working on something this size (about 200K products) I had a home grown app I used to generate unique ad text using common elements from the products datatbase. You may want to use DKI as well, although that would depend on the specifics of your situation.
