Why is the adwords api so expensive? It should be completely free, don’t Google want us to use their system. Wrote a php script to add loads of keywords and ran it on a test run to insert about 3000 keywords with a seperate adgroup for every 2 keywords, so 1500 ad groups. I knew the API costs money but I thought it would be miniscule. $80 that run cost me! I feel like ringing Joe Duffy.
