In Piano Insight, page views from content recommendation clicks include the custom parameter cx_source=cxrecs.
You can also add your own custom parameters as query parameters on the click URL.
Example: use this with itemDefaults to distinguish clicks from different branches
(similar to tag paths in the Content applications).
<!--%
var items = data.response.items;
for (var i = 0; i < items.length; i++) {
var item = items[i];
var itemsrc = item.src || 'generic'; # get the injected item key/value or set a default
var tagged_click_url = item.click_url + '?cx_tag=' + itemsrc; # add it as a custom parameter to the click_url
%-->
<div class="item">
<!-- use the tagged_click_url instead of item.click_url -->
<a class="allclick" tmp:id="{{cX.clickTracker(tagged_click_url)}}" tmp:href="{{item.url}}" tmp:target="_top">
