Questions, answered
How accurate is this?
It’s a planning estimate. Real results depend on your keywords, ads, landing page and competition. Use your own Google Ads data when you have it.
Where do I find my cost per click?
In Google Ads (Campaigns → Avg. CPC) or, before launching, from Keyword Planner’s “top of page bid” range.
What’s a good return on ad spend?
It depends on your margins. Many service businesses aim for 4× or more; low-margin products often need higher.
What are the industry presets based on?
Rough GCC averages for search campaigns. Treat them as a starting point and replace them with your own figures.
