Is a lead/contact added automatically to targeting campaigns on Google, Fb LinkedIn?

Hello, 

I would like to know 

A lead enters CRM through several paths... website, import, manually entered in the system etc. Then it should automatically be added in a list which also automatically should be used for targeting Audience in Marketing  Campaigns via Google, Linked In and Facebook.

Does this happen automatically ? Is there such an option ? If no ... What is the process that we need to follow ? If you have a YouTube link tutorial on the matter please refer it to me.

Also please help me with the below issue:

At which points should we create an automation in CRM?

How we are to use an existing feature of crm (i.e. add a campaign to the deal) ?

Thank you,
