> why bother with the bloat of ad networks

Except a few very rare cases, ad networks can statistically deliver a far more effective ad than a manually curated ad.

The network also has the infrastructure in place to track the user all the way from the ad click to completing a purchase, potentially across many devices or even in a physical store. They use those numbers to demonstrate their value with hard figures rather than marketing fluff.
