This leads me to one of the really great reasons to use the WunderCounter. You can (and should) use it to track the success of your ads, email campaigns and marketing initiatives. Since the WunderCounter is not affiliated with the 3rd party which you are buying your services from, there is no conflict of interest in getting you an honest breakdown of your web traffic. There's no pressure to over inflate the success of your marketing initiative or even to suppress potential click fraud. It's in my best interest to get you the most accurate stats which I possibly can, because this is a service which helps you to keep other services honest.
For example, if you're paying for your ads by the click, do you trust the click reports which your ad provider sends you? How thorough are these reports? Do they drill down to the individual clicks? If not, how are you to know that there is no click fraud being perpetrated on your ads? If you are getting a breakdown by IP, can you trust it 100%? If you have been billed for fraudulent activity, how likely is your ad provider to let you know about it?
Your ad provider wants to bill you for as many clicks as possible. Your email delivery provider wants to prove to you that a very high percentage of your messages have been successfully delivered and opened. Are you really getting what you've paid for? Whom are you going to trust to tell you what really happened with the money you've spent?
Think about it. Keeping companies honest ranges from uncovering dishonest business practices to discovering sloppy accounting or oversights on their part. It's easy to track the success of your ads and emails yourself, so why not gather this info for comparison? You may be surprised at what you find.
