Event Types in Rules and the order

Hi, 

These are more generic HTML events and not specific to Adobe Launch (now rebranded as Data Collection Tags). The below summary was taken from here: https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-questions/recommended-event-type-while-setting-rule-in-adobe-launch/m-p/362715 which I highly recommend to read.

1. DOM Ready should fire when the code is on the page, but not necessarily rendered

2. Window Loaded should be when all the content has completely loading

3. Lib Loaded is basically in the head of the document

4. Page Bottom is sort of the opposite of Lib Loaded, where the call should be the last item in the body

I would also recommend these articles for a better understanding of where to put your JS files according to your requirements:

I hope this helps.
