I’m not sure but this seems like the first time they’ve made specific traffic increase predictions. Here, they point out
Daily budget of $100.00 met on 13 of the last 15 days. Increasing your budget to the recommended amount would allow your ads to show 118% more often and get approximately 784 more clicks per month.
Yeah, more traffic. But is it the right kind of traffic? Only a watchful eye can tell that. Sadly, many amateur PPC marketers will just go with the recommendation without thinking.
