Basically the reason that doesn't happen is because such a business model of matching blog one by one with advertizers doesn't scale - neither for the buyer, not for the seller.
The person making such a market cannot make a living out of it without automation unless the blog comes off the bat with millions of viewers (think top YouTube channel content creators who get sponsorship). With automation comes the need for tracking.
Almost always this has a highly enforced anonymity - since the behavioral signal is more valuable than knowing who exactly you are.
