A simple formula for assessing the feasibility of AdWords cases

english

Update [24th March, 2017]: In addition to the formula explained in the post, I would add the following general criteria for a good AdWords case: 1) Low-Medium competition (high CPCs force to look for alternative channels), 2) Good website/landing pages (i.e., load fast, easy to navigate, have text information relevant to the keywords.

Introduction

Google AdWords is a form of on-demand marketing which matches demand (keywords) with supply (ads). Because it provides good relevance between demand and supply, it efficiently fulfills the core purpose of marketing which is, again, to match supply and demand. However, while this property of AdWords makes it generally much more effective than other forms of online marketing, it also leads to a major limitation: the campaigns cannot scale beyond natural search volumes.

I often tell this to my students participating in the Google Online Marketing Challenge (GOMC), but a few of them always fall into the “trap of low search volume”. I will explain this in the following.

Selection criteria

First, the relevant dimensions for assessing the potential in AdWords are:

  • geographic range: the based on the company’s offerings
  • product range

These can vary from low to high so that

Low geographic range x Low product range = Trap of low search volume

Low geographic range x High product range = Potential risk of low search volume

High geographic range x Low product range = Potential risk of low search volume

High geographic range x High product range = High search volume (Best case for AdWords)

In other words, this formula favors companies with nationwide distribution and large product range. These campaigns tend to scale the best and offer the best ratio between cost and value of optimization. In contrast, local business with one or two products or services are the least feasible candidates.

What does the trap of limited search volume mean?

Well, first of all it means the spend will be low. In GOMC, this means some teams struggle to spend the required $250 during the three-week campaign window.

Second, and more importantly, it means these cases are less interesting for marketers. They offer little room for optimization (because spend is low and there is very little data to work with).

Also for this reason the management cost of running these campaigns (=the amount a marketer can charge for his/her services) can become unbalanced: for example, if the yearly spend of a low-volume campaign is, say $400 and the marketers charges $100 per hour for his/her work, there is no point for client to pay for many working hours, as their cost quickly exceeds that of the media budget.

Conclusion

As a marketer, you always want to select the best case to amplify with your skills. You can think of it through two dimensions:

  • marketing
  • product

By multiplying them, we get the following.

Bad marketing x Bad product = Bad results

Bad marketing x Good product = Okay results

Good marketing x Bad product = Bad results

Good marketing x Good product = Good results

The same in numbers:

0 x 0 = 0

0 x 1 = 0

1 x 0 = 0

1 x 1 = 1

In other words, it makes sense to choose a case which is good for you as a marketer. A good case will work decently with bad marketing, but not vice versa. And only coupled with good marketing will the maximum potential of a good product be achieved.

How to calculate metrics for an AdWords campaign plan

english

I teach this very simple formula to my students when they are required to write a pre-campaign report for the Google Online Marketing Challenge (GOMC).

You want to report metrics in a table like this:

budget    ctr      cpc    clicks    impressions
250         0,05   0,2     1250    25000

(The numbers are examples.)

To calculate estimates for a campaign plan, you only need to know three figures:

  • budget
  • goal CTR
  • goal CPC

In the case of GOMC, the budget is set to $250. In other marketing cases, it is based on your marketing plan.

Goal CTR is what you want to accomplish with your ads. I usually say a CTR of 5% is a good target. Based on bidding strategy and competition, however, it can range between 3 and 10%. Less than 3% is not desirable, as it indicates poor relevance between keywords and ads.

Goal CPC is what you want to pay for clicks. Ideally, you want the CTR to be as high as possible and CPC as low as possible to maximize traffic (website visitors). The actual figure will be based on competition as well as your quality score (to which CTR contributes, among other factors of relevance).
Quality score can be enabled by customizing columns in keyword view; the bid estimates for your keywords can be retrieved via Keyword planner, as well as by looking at bid estimates (first-page and top-of-page) in the keyword view. In Finland, I usually say €0.2 is a good target for average CPC. In other markets, the CPC tends to be higher.

Out of the previous figures, you can calculate other metrics:

  • clicks = budget / cpc
  • impressions = clicks / ctr

The calculation assumes full usage of budget, which is not always possible when organic search volumes limit the growth (this is just a general limitation of search advertising).
