Spending vs Traffic Rankings

Traffic and revenue tell two different stories
Why it spread
It spread because a big source account with 96,009 views and 337 likes, roughly its normal level at 1.0x, paired a slope chart with a sharp two story framing about spending and traffic.
What worked
- The post text sets up a tension between traffic and revenue, then names Replit as a top 10 app by spend and a bottom 5 app by traffic.
- The slope chart is an unusual chart type that shows spending and traffic producing different rankings for selected products.
- The source line is shown and the source reach sits in the top quarter, which lends credibility to the full Top 50 list.
What to borrow
We could use a slope chart to show how two different measures rank the same products differently, and open with a one line tension that names the biggest gap.
Careful
Do not over read the engagement as proof of the finding, since likes match the account's typical level, quote rate is below average, and the chart only covers selected products.
