Well, you should have the proper UTM tracking strategy in place to track the engagements coming in from different mediums and sources. There are a lot of posts, questions, and knowledge-base articles posted around this in the community already if you search. You can also autofill hidden fields on your Marketo forms with the UTM values for tracking purposes. The Munchkin also tracks the UTMs along with the URLs, so you'd have the visit engagement data logged in the Marketo as well (logged in the Activity Log only if the Munchkin token is associated with the person record).
Why would you want to integrate Google Search with Marketo? Did you mean integrating Google AdWords with Marketo to upload offline conversion data from Marketo to Google AdWords instead? With AdWords integrated with Marketo, you'd be able to see the Ad clicks that resulted in qualified leads, opportunities, and conversions after you add custom columns in AdWords.
