#3. You are the PM for a B2C product that has an advertisement-based monetization model with significant and steady daily revenues. One day, there are no ads served and the revenues plummet to zero. What would be your strategy, as a Product Manager, to deal with this crisis?

Assumption - The product is an advertising platform where a seller can publish their ads and they are directly presented to consumers. Monetization for advertising platforms is usually based on:

• Impressions - number of ads served

• Clicks - Users actually clicking on the ad

• Actions - Users performing certain actions such as signup or add to cart after clicking on the ad.

The problem states no ads were served which means the impressions revenue is down. The problem states that revenue plummeted which would imply this was sudden and we didn't notice any steady decline.

Advertising platforms have two distinct user groups:

Publishers - advertisers who define a campaign and post it on the platform.

Consumers - Customers who see the ad in a platform such as facebook or instagram.

To root cause this issue I would dig into metrics for both set of users.

Publishers -

1. Daily average advertisements published on platform.

2. DAU for publishers

If there is a drop in either of these metrics I would look investigate the following possible reasons

Technical reasons:

• New code deployed to the publishing platform

• Infrastructure health issues - broken servers or provider outages … Read More and Give Feedback
