Marketing KPIs * Sale CRM Integration

Hi, I am fairly new to Monday so forgive my novice question! Our team will be using the sales CRM which we are finding very useful so far! I am part of the marketing team and need to be able to track where leads are coming from so that I can establish my marketing KPIs. How does everyone else approach this? I will be integrating MailChimp and using the Monday form on the website. But, how do people track website traffic, for example on Monday? Can Analytics be integrated? Any insights or examples of how to use Monday as part of your marketing strategy will be greatly appreciated! Thanks in advance
