Can you manage your inventory with Google Shopping?

We are often asked by our clients if we can use Google Shopping or paid search to push particular products or product groups.
There are a number of reasons why they might want to do this. They might have high stock levels of a particular product; some ranges might be out of date, and they wish to sell off remaining stock; or perhaps a product is not selling as well as they had hoped, and they wish to boost the sales.
On the face of it, Google Shopping seems like a good platform for this task. Advertisers can pay more to increase the exposure of a particular product, rather than bid on keywords alone (as is the case with standard text ads). Hence, advertisers often believe Google Shopping is the ideal means to proactively manage inventory and stock levels.
