Case Study: Optimization of Google campaigns with weather data

Campaign success with Weather Driven Advertising 

Weather and climate have major influence on our leisure and consumer behavior. This affects almost all industries – including app providers such as wetter.com. Online weather portals and weather apps can use their own expertise and knowledge of weather effects to optimize their campaign planning.  

In summer 2023, our colleagues from wetter.com therefore set themselves the goal of optimizing the performance of their Google campaigns.  The aim was to improve retention rates and user acquisition by generating additional weather-based campaigns while maintaining the same costs per install. But how exactly can such complex, regional weather-based campaigns be managed as precisely and convenient as possible? 

App Users waiting for rain… 

A short glance at the sky is no longer enough for a lot of app users these days. They want to know as precisely as possible what weather conditions they have to expect in the upcoming hours and days so that they can be prepared as best as possible. In summer we want to know whether the temperatures are finally heading towards bathing weather, and in autumn we want to be warned of storms and thunderstorms in good time, while at the beginning of the winter months, the first snow and the associated frosty and icy conditions are eagerly awaited by many. Depending on the weather conditions, we check our weather app(s) several times a day. 

Additionally global warming is causing certain extreme weather events to occur more frequently and much more locally. The desire of users to be well prepared with a short glance at their weather app is therefore increasing even further. As a result, weather portals and apps such as wetter.com are experiencing significantly higher usage rates and an increased number of new installations in the affected region, especially during unusual weather conditions – such as extreme temperatures, severe thunderstorms, hailstorms or black ice. 

Weather apps can take advantage of their own expertise and use the knowledge about extreme weather events to further optimize their app installs during specific weather conditions. The higher usage and increased number of new installations during exceptional weather conditions is also due to the fact that ads from weather apps are much more relevant for users on these days. That makes the generation of additional Google campaigns with appropriate weather targeting a promising approach for campaign optimization. 

Generating additional campaigns with Weather Targeting 

These campaigns, which run in addition to the “always-on” campaigns, ensure that more volume can be generated on certain days. The implementation takes place at regional level (e.g. federal state) and the weather information is transferred to Google Ads via a special script. The daily budget of the campaign is automatically being increased or decreased depending on which weather conditions are being predicted. The Smart Bidding logics are not affected, as Google automatically adjusts them to the previously defined target (e.g. tCPI, tCPA, tROAS). 

The Google algorithm also reacts to corresponding weather conditions, but it is very sluggish. The “always-on” campaigns very quickly reach their capacities here. The additional campaigns are ready to go even before the unusual weather conditions take place, as the METEONOMIQS weather script runs every day in the early morning. Thanks to the data preparation and support provided by METEONOMIQS, there is no need for a massive query of a weather API. 



Our regional script- and weather-based campaigns on Google show that, compared to standard campaigns, in exceptional weather conditions we can acquire better quality users at the same cost per install, who are interested in the app and the content in the long term!“  (Anton Stopka, Senior Performance Marketing Manager at wetter.com)

The weather conditions at the user’s location are a decisive factor influencing the usage of online portals or apps such as wetter.com. Especially the weather influences whether and which products are sold. However, these effects can change rapidly and also vary a lot from region to region. 

These insights are necessary in order to advertise based on the weather, so that users can be reached with the right messages in a targeted manner. In this respect, our plug-and-play solution for various advertising channels automatically takes the local weather differences into account. In this way, we make weather targeting simple, efficient, and entirely without the use of cookies.

Case study: How pollen targeting increases the efficiency of programmatic campaigns
Weather concerns all of us and we want to be as prepared as possible. For many consumers, pollen count also plays an important role here, which in turn is heavily dependent on weather and climate. Over 60 million people in Europe are affected by hay fever - a large target group that the pharmaceutical company Sanofi wanted to reach specifically when it launched its pollen medication "Allegra" in Germany in 2023’s pollen season by using METEONOMIQS pollen data.
