A conversion is the desired action that website owners would like visitors to take. For eCommerce sites, a conversion is typically a sale. However, conversions can be many different types of actions. Some common actions that function as conversions include:
Making a successful purchase
Submitting a contact form
Visiting a key page
Signing up for a newsletter or other service
Engaging in a live chat
Clicking on an advertisement
Spending a given amount of time on a page or site
Leaving a review
Conversions are often referred to interchangeably as goals, and much of online marketing is centered around strategies for increasing conversions.
