ROAS = Profit (It's Just Harder To See It)

There are (too) many digital marketers who, when you talk to them about profit, say that they don't measure profit. "I don't need to measure profit, I measure ROAS, ROAS is a best practice".

The fun part of the comment is that the digital marketer IS measuring profit, s/he just doesn't realize it.

Here's a table for a digital marketing initiative, broken down into deciles for the sake of illustration.

We see total results on the left - I converted the results to incremental outcomes by decile. In this example, deciles 7/8/9/10 lost money, they were unprofitable.

Now look at Incremental ROAS on the far right. An approximate Incremental ROAS of $2.25 is unprofitable. Anything below that is unprofitable.

If you have the discipline to keep incremental activities above a 2.25 ROAS, you're generating profit. Good for you!
