However, ads may not be suitable for some customers due to competitive industries, low budgets, or lack of optimized conversion paths. The document then addresses common objections to ads, stating that the HubSpot add-on aims to make ads setup easy, provide expertise, and clearly show ROI. Key features highlighted are automatic tracking, ROI reporting, and optimizations to learn best practices.
