Use case example: Words in ad headline and cost per click (CPC) analysis
Bubble chart in this example analyzes correlation between number of words in social media ad headline, click through rate (CTR) and cost per click (CPC).
Number of words in ad headline are plotted on X-axis. Click through rates (CTR) are plotted on Y-axis. Cost per click (CPC) is plotted in form of bubble at the intersection of X and Y-axis. CPC value determines the diameter / size of each bubble. Larger the CPC, bigger is the bubble size.
As you can see, 5 word ad headlines get highest CTR (25%), with a CPC of $2.35. Ads with 6 words in headline reported not only low CTR but also high CPC (and hence the largest bubble size).
You can also use this line chart template to compare cost per click (CPC) for various digital marketing campaigns.
