We often come across a word clickTag while using online programmatic advertising platforms. So What exactly is a clickTag?

For one of our dear clients, we built hundreds of HTML5 Ads that displayed service locations, these ads were shown to prospects in respective locations. Such kind of personalization requires multiple files of ads, and the challenge we faced was ad testing.

We needed an ad previewer that works fast and shows all the ads in a single-window after uploading them so we can test their animation, CSS styling, data accuracy, and consistency. The only tool we could think of was an HTML5 ad validator by Google, but for some important reason, we built our own tool this time.
