In early June, we announced the Conversion Champion Challenge, a contest challenging you to use free AdWords conversion products to increase your ROI, then submit a mini-case study telling us about your experience. The grand prize winner will receive an AdWords voucher as well as an all-expenses paid trip to Google Mountain View or Google Zurich, where the Google Conversions team will meet with you to review your account and provide customized recommendations.

For those of you who took us up on the challenge, final entries are due tomorrow, July 31 and can be submitted here. So get those entries in soon!
