 **Kind**: static method of pbjs API
 
+`options.clickThrough` optionally enables publishers to count clicks on prebid inventory in their distributing adserver.
+The publisher may call renderAd with a third param accepting an object where the value of clickThrough will be checked.
+If this property is set the value of clickThrough will replace any occurrence of ${CLICKTHROUGH} inside of the properties ad and adUrl. If no match is found nothing will be replaced.
+
+{: .alert.alert-info :}
+Note: In regards to `options.clickThrough`:
+- To make use of this feature, bid adapters would be required to respond with ad tags including the ${CLICKTHROUGH} macro.
+- The renderAd function must be invoked with the options argument. Ex: `renderAd(doc, bidId, {clickThrough: 'https://someadserverclickurl.com'});`
+- Not compatible with safeframes (since the logic around rendering safeframe's does not invoke the renderAd function).
+- Not supported with Prebid Universal Creative at this time, only the standard pbjs.renderAd method.
