Imagine my surprise to see a large travel company still running ads for Wow Air. At this point operations had been ceased for around ten hours. Ads for such a competitive market would probably cost one to six dollars per click. And with Wow Air being in the news curious people probably clicked that ad to see what was being sold in addition to people who wanted to travel to Iceland. I clicked it. It was a branded page but when I dug into the options Wow Air was already removed from the list of carriers. This highlights the different speeds with with different departments react to changes. And moreso, it highlights the lack of communication in businesses. Someone, probably many someones, knew that Wow Air was no more so they removed it as a flight carrier option. They did not, it would seem, reach out to Marketing and say, "Hey, you'll want to disable your ads." This is the downside of work silos. It would never have crossed their minds that such a thing could be helpful. Besides it is not their job...
For small businesses and account managers, it often isn't a problem to respond to an issue within 24 hours. Something I use and have shared with some account managers is Google Alerts. This works well but can take a day to get an alert. Basically, you get notified if some keywords you specify are referenced when a new webpage gets indexed. This might not help you if an existing webpage is updated. It depends on whether your keywords didn't use to match but do after the webpage is re-indexed.
For things that need immediate handling when there is a change then that usually requires being proactive. For example, there are lots of services that will notify you within a few minutes that a webpage has changed. In this case, if you are the person handling Ads for Wow Air then you would probably want to know anytime the main landing page changes. Most of the time the changes won't matter to you but they could reflect a need to update your ads or in an extreme case - this case - the need to disable your ads. Several years ago, I had a job where it was very helpful for me to know when and if a set of services were down or had changed. I used https://www.runscope.com/ to notify me if a set of tests didn't pass.
As a software engineer, it is really valuable to listen to the problems that your coworkers are facing, even the ones in different departments. You might hear an account manager complain about how much of a hassle it is to constantly check for press releases that relate to any of their accounts. Then you can helpfully share that you use Feedly to monitor the release of new webcomics and they could use it to get notified of press releases or anything online.
