How do you figure out your average CPC? You can do it in 2 ways.
First, if you are already running Google Ads, head to your campaign and look back to at least 3 months of campaign data. You will see the average CPC that you have been paying to Google.
The second option is if you do not have an ad account. Create one with Google Ads. Once done, go inside the dashboard and click “Tools” then “Keyword Planner”. Type in the main keywords that you want to show up for. You will see a table of the keywords and their average CPCs to rank on top of Page 1. Use them as a starting point.
