With limited prospects for growth, one of the iron laws of economic downturns is that advertising is among the first budgets to be cut.

Advertising revenues have already cratered at many alt-weekly newspapers, which heavily rely on local events and restaurants that have been shuttered in the wake of the COVID-19 outbreak. BuzzFeed even went so far (as they do) to label it a “media extinction event.”

Clearly it’s bad times, but I wanted to get a lot more granular around the data for ad rates, particularly around top startups. So I compiled a list of a little more than 100 unicorns across a variety of sectors and explored how the prices of their search engine keywords have changed with the global pandemic that is sparking a global recession.

The results aren’t surprising — there has been a collapse in prices for almost all ads (with some very interesting exceptions we will get to in a bit). But the variations across startups in their online ad performance says a lot about industries like food delivery and enterprise software, and also the long-term revenue performance of Google, Facebook and other digital advertising networks.

A quick overview of the data

It’s common for startups to buy their own keywords on search engines like Google and the App Store. Owning that top rank guarantees that their own company’s page is the first result a user sees and prevents competitors from buying their name, potentially intercepting customers.
