Baidu launched an Android app for its paid search platform where advertisers can check account balance, campaign performance; top up account, receive alert and optimize campaigns.
The Android app is currently in limited beta; if you want to give it a try, contact your Baidu representative and tell her your mobile number (where the link to download the app will be sent) and account number.
Baidu also launched a PPC performance analysis tool to give advertisers a quick overview of account performance. Impressions/Clicks, Cost/Impressions, Cost/Clicks quadrant graphs are available.
