Follow specific companies that you're targeting and you'll be able to see more clearly what type of content, web pages and campaigns they are interacting with. Once you have followed companies, the followed companies can be seen by selecting basic feed named Followed companies. You will also be sent a notification whenever those companies visit your site, though as with all feeds you can customize those notifications.
STEP 1: Click on the Follow button within the lead.
STEP 2: Now you will see the Followed companies feed with all Followed leads within it.
