Why negative keyword management matters a lot
If you’re not actively managing negatives, especially for Performance Max campaigns, Google will keep stretching when your ads show. The system is designed to find conversions, and it will keep trying to find searches that convert. Sometimes you can start getting conversions from keywords that are used by people who won’t ever rent, e.g., the “apartments that accept evictions,” which will provide positive reinforcement for this keyword and make the mess even bigger.
What happens over time:
- You start paying more for irrelevant clicks
- Conversion rates from lead to lease collapse
- Cost per lease creeps up
Sometimes, negative keyword management is tricky. We recently saw the search term “modern apartments” appear across most of our clients’ accounts. On the surface, it sounds relevant. But to our trained eye, the conversion behavior didn’t make sense (e.g., 3 conversions from 1 very high cost click in many accounts). We added this as a negative keyword to our keyword list.
That’s the kind of thing that slips through if you’re not paying attention, and if you are managing Google Ads in-house, you might feel pressure to let it slide. We had more than one debate with our clients about this decision, which was an extremely obvious problem to us.
