* Note: Asynchronous code is faster than Simple
Tips: Put tracking code on the web pages you want to track. This may be every page for smaller sites, or only key pages on sites that have many dynamically generated Web pages, user forums, and so on.
Landing pages created in Marketo automatically have tracking code, therefore you do not have to put this code on them
