Ads can also communicate something about the quality of a branch/product based on how much the ad cost to run and which publication chose to run the ad. This is no substitute for a review, but if I see a non-targeted ad for an SSD in a tech publication that chooses ads based on what it thinks is good (I'm describing The Deck basically) it at least assures me that this SSD is not a hunk of garbage. Again this is not a lot, but a targeted ad tells me
nothing.
On the flip side of this, if Vogue let any old crap run as advertising in their magazine this would be a form of reputation mining - trading their good name (earned after years of operation) for some short-term profit, but no-one bats an eye when the same thing happens online even though it's subtly devaluing online properties that do the same.
