In order to check for proper implementation of our tags on specific elements, you can use the Tag Inspector plugin we have made available to our clients on Chrome.
Once this plugin is installed on your browser you can load a page or click a button from your site with the plugin open, and see the hits come through with information that is sent to our collection servers for processing.
To check the implementation of our tags on an entire site, you can also crawl the site using Tag Crawler.
