How Much Should You Spend on Google AdWords?

One of the most frequent questions I receive about Google AdWords is, “How much should I be spending on my AdWords campaign?” That’s a great question, and the short answer is, “It depends.”

One of the most frequent questions I receive about Google AdWords is, “How much should I be spending on my AdWords campaign?” That’s a great question, and the short answer is, “It depends.” One of the great things about AdWords is that it is highly customizable, allowing you to make the decisions that best fit your business needs. The downside is that it is not easy to see at a glance how best to manage your AdWords budget.

Fortunately, we have developed a formula that allows you to plug in your numbers and calculate a realistic budget. It breaks down into two phases: Testing and ROI.

Phase 1: Testing

When you begin your Google AdWords campaign, you will need to test several ideas to see what works for you and what doesn’t. While some campaigns are profitable right out of the gate, many others are not. Consider your testing phase to be a form of market research, and plan to invest those dollars without the expectation of getting them back.

Before you begin, gather the following information:

  • Target Keywords Cost Per Click (CPC): Google AdWords follows a pay per click (PPC) model. No matter how many times your ad appears, you only pay when a prospect actually clicks on it. For each keyword, you will pay a different amount of money for that click. This is known as the CPC, or cost per click. For example, Google estimates that “coffee shop” costs $2.90 per click, while “mortgage broker” costs $13.76.

Make a list of the keywords that you want to test, and then use the Google AdWords Keyword Planner Tool to estimate the CPC for each of those keywords. Remember that this is just an estimate, so your actual cost may be higher or lower.

  • Time Frame: How long can you spend in the testing phase before you need to see your results? This is partly dependent on your industry and the keywords you choose. Some keywords have a higher search volume than others, making it easier to get results in a shorter time frame. Also consider your normal sales cycle. Do customers tend to purchase in one day, or does it take months for them to make up their minds? The lower your search volume and the longer your sales cycle, the longer it will take for you to obtain accurate data.
  • Sales Conversion Rates: As a general rule of thumb it’s safe to estimate that 1 in 100 people (1 percent) who view an AdWords ad will click on it, and 1 in 100 clicks (1 percent) will convert into a paying customer. These are estimates, and your ads might drive more or less traffic, but they work for planning purposes in the testing phase.

Now you are ready to put together your testing budget:

  • Per Keyword Cost to Test: If you can turn 1 in 100 clicks into a customer, then the estimated cost per sale is the cost per click (CPC) divided by 1 percent. For example, a keyword that costs $3 per click will cost you an estimated $300 for one sale. Go through the same process for each keyword you want to test, and add up the results to get your total budget.
  • Monthly Testing Budget: To generate a per-month Google AdWords budget, divide your total keyword costs to test by the number of months you want to allot to the testing phase. For example, if your total costs calculated earlier are $2,000, then you could budget $500 per month for 4 months. Or if you wanted to test faster, then $1,000 per month for 2 months.

Phase 2: ROI

Once your testing phase is complete, and you have generated a handful of sales from your ads, then it’s time to move into the ROI phase. The goal here is obviously to maximize return on investment from AdWords.

What should your budget be in the ROI phase? If your ads are profitable, then the answer is you should ditch your budget altogether! If every dollar you spend nets you more than a dollar in sales, it only makes sense to invest as many dollars as possible.

While many businesses focus on writing better ads, which improves the AdWords quality score and reduces the cost per click (CPC), that’s only half of the equation. The real magic comes from the EPC, or earnings per click.

To find your EPC, just multiply your customer value times your conversion rate. Your Customer Value is the average amount that one customer spends on your product or service minus your fulfillment costs. Your conversion rate is the percentage of clicks that become paying customers. So if the customer value is $100 and you have a 1 percent conversion rate, your EPC is $1.00.

Why Is EPC so important?

Well, it tells you exactly how much you can afford to pay per click for every single keyword in your account! If you pay more than your EPC, then you’ll be unprofitable. If you pay less, then you’re profitable. It’s as simple as that.

That means the key to AdWords success is to maximize your EPC by increasing both your customer value and your conversion rates.

Google AdWords is a highly customizable and extremely powerful advertising network, but it can be a bit overwhelming for newcomers. That’s why I put together an AdWords checklist to help you get your campaigns set up for success. Click here to get my Google AdWords checklist.

Marketing ROI in B-to-B: Why Is It So Hard, and What Can We Do About It?

The other day, I had the pleasure of discussing the challenges of marketing ROI with Jim Obermayer, CEO and executive director of the Sales Lead Management Association, on his Internet radio show. Our conversation got me thinking: Why is the Holy Grail of marketing ROI so tough to achieve in business markets? And what can we do about it?

The other day, I had the pleasure of discussing the challenges of marketing ROI with Jim Obermayer, CEO and executive director of the Sales Lead Management Association, on his Internet radio show. Our conversation got me thinking: Why is the Holy Grail of marketing ROI so tough to achieve in business markets? And what can we do about it?

The “why” part is pretty clear: Business buying cycles tend to be long, and involve multiple parties at either end. Marketers produce campaigns to generate an inquiry, and then qualify that interest with a series of outbound communications, and finally pass the qualified lead to a sales rep for follow up. From that point, it can take more than a year to close, and involve a slew of people on the customer side, from purchasing agents, to technical specifiers, to decision-makers.

The sales process is also complex, involving not only the face-to-face account rep, but sales engineers, inside sales people, and others who help get all the buyers’ questions answered, negotiate the terms, deliver, install and trouble-shoot the product, and whatever else needs to be done to satisfy the customer’s needs.

So, consider the difficulty of establishing the numbers that go into an ROI calculation in this kind of situation. Just to put a definition behind the concept: ROI, meaning return on investment, subtracts the marketing expense from the revenue generated, and then divides by the expense, resulting in a percentage that shows how much net return was produced by the investment.

But in this lengthy, multi-party, multi-touch selling situation, the “investment” part can be pretty tough to get at. Frankly, it’s a bit of a cost accounting nightmare, assigning an expense number to each sales and marketing touch that resulted in a particular closed deal. This brings up issues of variable versus fixed costs, marketing touch attribution—the list goes on and on.

Worse, the “return” part presents its own challenges. First problem is connecting a particular lead to a particular piece of revenue, which means carefully tracking a lead over its multi-month process toward closure.

Further, if a third-party distributor or agent is working the lead, it’s very likely that revenue results reporting is not part of the deal. With good reason: The distributor considers the relationship with the end-customer as his, and none of the manufacturer’s business. So the marketer who generated the lead often has no visibility into the associated revenue. Even if the deal was closed by a house rep, you’re looking at the endless squabble between sales and marketing about who gets the credit.

You can’t blame B-to-B marketers for throwing up their hands and relying on interim metrics like response rate and cost per lead. Especially when marketing staffers come and go, and may not even be in the job when the lead generated a while ago finally converts to a sale.

This is why I was so pleased at the arrival of the new book by Debbie Qaqish, The Rise of the Revenue Marketer, where she urges marketers to raise consciousness of their role in driving revenue results. “The revenue marketer uses the language of business,” she says. Examples of the metrics she recommends for revenue marketers include funnel velocity, sales conversion rates, pipeline revenue and campaign ROI.

My conclusions from this investigation:

  • Begin with a deep conversation with your finance counterparts to get at the best way for marketing to serve your company’s financial interests, like:
    • The right approach to assigning sales and marketing expense.
    • Whether to calculate returns based on net sales or on gross margin.
    • Decide which expenses are fixed and which are variable.
    • How to attribute the contribution of sales and marketing touches across the sales cycle.
    • Setting the ROI “hurdle rate” needed to support your company’s profitability goals.
  • Figure out where to get the revenue and expense data—not everything will be in your CRM system. Your finance counterparts should be help you source the data you need.
    • If a distribution channel party is a roadblock to revenue visibility, conduct a “did you buy” survey into accounts to which qualified leads were passed.
    • If the account-based revenue is captured internally, try supplementing your CRM system with data match-back to connect campaigns to sales, circumventing the arduous process of following a lead along its complex conversion process.
  • Set clear objectives for each marketing expenditure, so you know how to declare ROI success when you see it.
  • Get inspiration from The Rise of the Revenue Marketer, Debbie Qaqish’s innovative thinking on the role of marketing in B-to-B.
  • Get an education from Jim Lenskold’s 2003 classic, Marketing ROI: The Path to Campaign, Customer and Corporate Profitability.
  • If to many obstacles are in the way, fall back and rely on “activity-based” metrics like cost per inquiry and cost per qualified lead, which tend to be pretty easy to calculate, being mostly within the purview of marketing.
