What Is Your conversion Value?
We would like to illustrate the importance of setting your conversion values by using a simple numerical example.
In our example, a hairdresser’s shop has two ad groups within its campaign, both aimed at acquiring customers. The first ad group’s theme is hair cut, while the second ad group’s theme is unisex hairdressers. Theme means a subject matter your keywords are grouped around.
In a particular week, the first ad group brings in 200 clicks at $0.50 each. Hair cut being a rather simple theme, only 1 in 20 clicks delivers a customer. The total spend of the ad was $100 and it resulted in 10 customers; in other words, one costumer costs $10. This is called cost-per-conversion. In the same period of time, the second ad group brings in 50 clicks at $2.00 each. Since unisex hairdressers is a bit more specific theme, 1 in 5 clicks brings a customer. In this case, like in the first ad group, the total spend is $100, and it also resulted in 10 customers. The cost-per-conversion, which we sometimes also term as cost-per-acquisition, is $10 in this ad group as well.
Let us compare the two situations with special regard to profitability.
Since the amount spent on acquiring a customer is $10 in both cases, the shop owner may conclude that the two ad groups are equally profitable, even though a click costs four times more in the second ad group ($2.00) than in the first one ($0.50). This may seem reasonable as long as the conversion value is not factored in, as this important metric can completely change the scenario. If the shop owner finds that a customer from the hair cut ad group results in $30 of profit, while a client from the unisex hairdressers ad group results in $40, he may want to set these amounts as the respective conversion values in the ad groups. In this case, 10 customers would generate $300 in profit in the first ad group and $400 in the second. Since the total spent on each ad group was $100, it may be concluded that the return-on-ad-spend (ROAS) is $300/$100=3 in the first ad group and $400/$100=4 in the second group. Based on this, the shop owner may correctly conclude that assigning more of the budget to the second ad group and less to the first one is advisable.
The above example illustrates that while cost-per-conversion is a highly important metric, profitability can best be measured by ROAS. When your advertising is driven by cost-per-conversion, you minimize the amount spent per customer on advertising, but this does not always tell you much about profits. On the other hand, when your attention is focused on ROAS and you designate it to be the driving force behind your efforts, you will optimize the profits derived from advertising—which is closely related to your bottom line. In plain English, it’s well worth watching how much a customer costs you, but what really matters relative to your bottom line is how much can be gained in profits by one dollar spent on advertising. This is why it is so vital to set conversion values in your advertising interface.
