If you advertise using Adwords it has been a little tricky in the past to determine where and if you ads are running - especially if you are not in a particular location. But Google has taken care of this with their new ad preview tool.
The tool offers a number of new features and will prove handy to most Adwords advertisers. You can isolate by mobile application, "so you can check ad visibility on multiple devices without borrowing all of your friends' phones!" the Adwords blog explains.
If you ad is not running "the Preview Tool will tell you why, helping you understand if you need to adjust your bids, location targeting, daily budget, or optimize your account" - now that will be handy.
With the changes being seen Adwords left side ads recently any help understanding how and when and why ads show and don't show is appreciated.
"You can explore these new features by finding the Ad Preview Tool under the Reporting and Tools tab in your AdWords account or by navigating directly to www.google.com/adpreview."
