The Great CPC Hoax: Why Cost Per Click Doesn’t Matter to Creating High-ROI Ad Campaigns

People always ask me the same question about Adwords:

“What’s a ‘good’ cost per click?”

And my response back to them is always the same:

“Why do you care?”

See, most people have AdWords wrong. They obsess over the costs.

They know that more and more competitors are advertising on the platform, which drives up prices.

So they’re zeroed-in on how much they’re going to have to spend.

But that’s the wrong approach. They shouldn’t be asking that question.

Instead, they should be concerned with what they’re going to get back in return.

I know this sounds counterintuitive. However, I almost never worry about the Cost Per Click for keywords.

In fact, I almost ignore them.

I’m going to show you why CPC’s don’t matter in many cases. I’ll show you how worrying about keyword costs can mislead you time and time again.

And then I’ll also unveil what you should be analyzing to make sure you’re not leaving tons of money on the table.

Why Cost Per Clicks don’t matter (and what you should analyze, instead)

Each year, companies analyze the most expensive keywords in the country.

These are typically competitive phrases in law or insurance. They might top $50 for just a single click.

The insane thing to remember is that almost none of those clicks will turn into customers immediately.

Instead, they’ll usually opt-into a form, first.

That means you might have to front the bill for 50 or 100 clicks before someone ever converts.

So already, we’re talking thousands of dollars for a single customer.

Almost all of these studies focus on AdWords’ Cost Per Click.

It makes sense when you think about it. That’s the primary unit of measurement they use.

It’s what ultimately determines how much you need to spend.

WordStream, for example, always releases an annual update on Cost Per Click benchmarks across industries.

The businesses I own are all software-related. But we work with clients across different industries. So it’s always interesting to look at these cost breakdowns.

Average ecommerce CPC’s might only be around a dollar, while law might run up to around six dollars.

To be honest, though, I don’t obsess over costs, alone.

The first reason comes down to what the study says at the top: Averages.

Average CPCs don’t really mean all that much.

Popular, generic terms aren’t usually all that expensive.

Only a tiny percentage of the people who ever click on those will convert. Whereas, a more commercial long-tail keyword will be incredibly expensive.

Just compare the difference in costs between “tax” and “file back taxes”:

See? It’s not even close.

That makes it hard to use a standard, “industry average benchmark” for any in-depth analysis.

However, there’s another reason why I don’t like to just look at costs.

And the reason is because you’re often forgetting the other side of the equation.

Conversions can ultimately have a much bigger impact than costs.

Now, let’s check out those industry average conversions from the same study:

Ok, now we’re getting a little closer.

If you remember, the industry average CPC for ecommerce was only around a dollar. In fact, it was one of cheapest CPC’s on the entire list.

But if you now look at the average conversion rates, you’ll see why.

Their conversion rates are also among the lowest at only around a percent or two.

Already, you can see part of the issue.

What does it matter if CPCs are ‘inexpensive’ if the conversions are equally low?

That’s why you often want to look at the Cost Per Action (or Acquisition) when putting together advertising estimates.

This is the effective price you pay to generate a lead, for instance.

It’s a performance ratio. It starts to take into account things like costs vs. conversions to help you determine a much better figure: ROI.

The industry average Cost Per Action for ecommerce lines up with education on the search network.

So from an ROI standpoint, there’s almost no difference.

This is why CPC becomes almost meaningless.

Yes, it’s important to a point because it drives things like your Cost Per Action.

However, what’s ultimately more important, is the revenue you can generate.

It doesn’t matter whether we’re talking about Google AdWords, Facebook, or even Twitter ads. The message is still the same.

Digital Marketer once ran a Twitter Lead Gen campaign, testing the effective Cost Per Action (or Lead).

One campaign was able to see a $7.81 cost per lead.

They then ran the same study with the same ad and audience targeting. But this time, they optimized the campaigns to increase conversions.

It generated a $1.38 Cost Per Lead, which came out to a five time lead increase on the same ad budget.

They were able to 5X conversions simply by focusing on conversions and Cost Per Lead. They didn’t even have to touch the CPC.

You can see this time and time again.

Jacob Baadsgaard of Disruptive Advertising confirms that the best PPC metrics are revenue-focused. They track lead data all the way through to closed sales.

Then, and only then, will they make a decision about which ad campaign is best.

It’s not that costs don’t matter. They do, of course. But they only matter in context to how much revenue you can generate from it.

Here’s a very simple example to illustrate.

Let’s say you run two ad campaigns side-by-side.

The Cost Per Click for the second campaign is twice as much as the first. But because the conversion rate is 2% instead of 1%, you’re able to double revenue.

Would you pay twice as high a Cost Per Click to generate twice as much revenue? Of course you would!

And this is after reducing revenue by your ad costs. So it’s already accounting for the higher ad budget.

At the end of the day, you’re still doubling revenue. It’s totally worth it!

Obsessing over CPC doesn’t just leave money on the table. It can also make you waste a ton of what you’re already spending.

Here are a few examples.

Obsessing over CPCs can make you pull the plug too early (or too late)

There are many things that separate big companies from small ones.

But here’s one of the biggest:

Big companies spend more on advertising than small ones do.

Gartner Research study found that bigger companies spend around 13% of revenue on advertising and marketing, while smaller ones only spend around 10%.

Sarah Brady found that those numbers leap dramatically in some industries, like tech. Salesforce, the world’s biggest CRM company, spends up to 49% on marketing and advertising!

Crazy, right?

Not only do bigger companies spend a bigger percentage of revenue on ads. But that also amounts to a much bigger number at the end of the day.

The question is why?

Why don’t small companies spend more on advertising?

In my experience, I find that they’re often too risk averse.

They don’t have the same access to capital. So they tend to obsess over costs, as opposed to revenues.

The classic scenario is when a business owner spends a few hundred bucks on new Facebook ads, only to conclude that they “don’t work” five days later.

They see that ad spend number continue to rise. And they don’t see the number of leads start to flow to justify it.

So they pull the plug too early.

In almost all cases, they just need to let the campaigns run longer.

Jennifer Shaheen found that campaigns should run at least 45 days before stopping. And that makes sense when you think about it.

Look at it this way.

How many sales do you need to break even? Let’s hypothetically say two or three.

So what are the chances that those two or three sales land in the first few days?

Pretty slim!

It’s the law of averages at work. You need a big sample size before numbers start to meet projections.

It’s going to take a few weeks, at least, to get statistically significant numbers. Otherwise, you’re just guessing.

And all of this assumes that you know the ‘right’ ad campaign variables ahead of time. Which, in all likelihood, you don’t.

Not because you’re not smart. But because it takes awhile to figure these things out!

Here’s the other thing that’s happening.

Many times, they actually need to increase ad spend.

Yes, you heard me right.


The only reason to advertise in the first place is to make money.

It’s not to save money on advertising.

That means you need to get to statistical significance as quickly as possible.

For example, go check out a few CPC ranges for keywords you’re about to bid on.

I like to use SpyFu to get a lot of this data:

The average CPC for “analytics software” is estimated to be around $11. Ok, not bad I guess.

Let’s use that as the upper limit. We can create automated rules in the Facebook Business Manager.

If you’re having a hard time hitting those numbers, you can set a rule to actually increase CPCs.

That will make sure I get better placement over the competition and as many conversions as possible.

Here’s how that might look inside AdEspresso:

But of course, this approach isn’t ideal.

Because you still might leave a lot of money on the table.

If your CPCs start edging up, the campaigns will back off or stop.

And then your lead flow will stop, too.

That’s why I like using CPAs as targets if possible, instead of CPCs.

Start by watching CPA instead of CPC

Cost Per Action is a better performance than Cost Per Click.

It’s not as good as Revenue, though. And therein lies the problem.

CPAs can still be subjective.

Is a ‘high’ CPA bad? Maybe, maybe not.

If your CPA is over $100 in ecommerce, that might be bad.

But almost every single campaign CPA will be over $100 in law, for example. So it’s not bad at all.

It still gives us a much better metric to control ad campaign performance, though.

You can still figure out an upper range that starts to make ad campaigns unprofitable. You’ll base this on your average sale per customer. (More on this later.)

For starters, you can set automated rules to increase or decrease the total budget based on your CPA.

Inside AdWords, you can go to “Bulk Actions” and create new “Rules” for these ranges:

Under “Change budgets,” you can set an automated rule to either increase or decrease budgets based on cost per conversion numbers.

This is telling AdWords to automatically increase your daily budget 25% if the CPA is within a certain dollar range.

You can do this same exact strategy inside Facebook, too.

You’ll set a rule to increase, decrease, or stop a campaign if the CPA hits a certain threshold.

Managing ad campaigns by CPA can net you more customers and revenue.

But there’s still one big section we’re forgetting.

Keyword pricing or competitive pressure aren’t the only factors to worry about.

Many times, your customer base could be going through their own issues.

And you can’t often do anything directly to change it.

That’s why focusing on revenue is always the best approach.

Now, increase the revenue-side of the equation to overcome outside factors

Spearmint Love was one of my favorite success stories over the past year.

They went from a baby blog to growing revenue over 991% year over year.

And they did it almost exclusively through
