Landing Pages have embedded webforms which also then trigger Thank You Pages. However, you can override webform settings to only trigger one. Thank You Page instead of having multiple-valued goals.
A goal only allows for 1 valued amount per session. For example, if a customer happens to fill a form 2 times during 1 visit to the website, it will only trigger 1 valued amount per session.
Events’ are valued differently, meaning they are not necessarily viewed in a $ amount unless you decide it’s what you want. A valued events with an exclamation point (!) are treated with value $ amounts. Those without, are not valued, only as a point system.
Events will allow for multiple value amounts per session. For example, if a customer shares an article with the Facebook, Twitter, email etc. share buttons, each click share will count as a separate event value. Even if for example, the Twitter share button is clicked twice, that will count as 2 event values.
