Other ways of rewarding affiliates

Is any of this possible?

Scenario 1
A user enters my site through an affiliate link placed on affiliates website. Several days go by and he gives us a call to place an order by phone. I find out the customer’s name and other information before selling to them. Can I somehow match that customer to the correct affiliate to give that affiliate their reward? The purchase was placed over the phone so how would I link the reward to the correct affiliate?

Scenario 2
We have several bloggers creating content on our site. I would like to give the bloggers a reward IF the user enters our site through one of their blog posts. In other words the user got on Google and searches for a topic, through the search they found the blog that’s hosted on our site but one of the bloggers created the post. So I would like to reward the blogger because it’s his post that got us the user into our site.
