Your Google Ads ROI (return on investment)

Our suggested CPC gives you a 42.86% return on investment.

Please note that your actual bids depend on multiple factors, such as:

  • keyword CPC
  • competitiveness
  • target ROI

If you can reach the #1 for your keyword at £20 per click and the optimal calculation returned £25, you’ll want to use the lower value for your bids. This will in turn also increase your ROI.

Similarly, if your current bid doesn’t guarantee the top spot under that keyword and the optimal value is higher, you should consider bringing your CPC up a notch. It would still be profitable and your ads will get more visibility.
