Automation has been a key part of PPC management for longer than many marketers realize, with the depth of automation now influencing campaign performance. Automation includes Smart Bidding, automated assets, dynamic targeting, and recommendation engines that handle tasks that previously require manual management. This is where PPC automation layering allows advertisers to combine multiple tools and signals to improve PPC efficiency and effectiveness. The use of these tools can include third-party automation tools like Google Ads Editor, Optmyzr, Adalysis, and more. Automated PPC rules can be implemented on a schedule based on the goal of the rule. However, this shift has led to a significant learning curve for marketers, with questions about whether automation will replace the need for job layoffs and restructuring due to automation.
