It’s easy to set up campaigns for lead generation or website optimization; you can also track them easily in dashboard section once they are live (the only thing I didn't like so far). The price of service might be too much if your campaign size exceed 500k monthly unique visitors - we use our paid plan mostly with 1M+ uniques per month but sometimes need extra plans when reaching 2-3 million pageviews/month which cost us about $200-$500 each time as one additional license costs 10x than normal package pricing! We used RDS primarily because there's always plenty leads available within minutes after launching any adwords ads while other solutions require manual work such push requests from users etc.; however most people will recommend using third party tools instead since its cheaper plus free trial period makes sure everything goes smoothly before paying big bucks upfront without risk involved. As mentioned above though some tasks requires bigger budgets compared smaller ones therefore make.
