An education provider, with numerous courses changing monthly, found it challenging to maintain a high Return on Ad Spend (ROAS) due to fluctuating search volumes for some niche courses requiring further research. Our strategy involved broader keyword research and smart budget allocation. By working on new broader research to improve search volumes and introducing shared budgets across new campaigns with a redefined ROAS strategy, we consistently achieved a ROAS of 4:1 to 5:1 every month, strengthening the account and enabling further scaling.
