Pay-per-click digital advertising can be one of the fastest ways for companies to build brand awareness, drive traffic to a site, and generate high-quality leads. Whether your company is just getting started with PPC advertising, or you’ve been running PPC campaigns for years, one of the biggest challenges is measuring the success of your efforts.

There are a few different ways for digital advertisers to measure success. Below, we’ll examine how to calculate:

  • Return on investment (ROI)
  • Return on ad spend (ROAS)
  • Profit per click

Calculating PPC ROI

Calculating ROI is one of the basic responsibilities of managing a PPC campaign. According to Google, ROI is usually “the most important measurement for advertisers because it shows the real effect that [a PPC campaign] has on your business.” While it’s important to keep tabs on vanity-type metrics, such as number of clicks and impressions, it’s often more valuable to understand how your PPC campaigns are contributing to the success of your business.

ROI is the ratio of your net profit to your total costs. When calculating the ROI from your PPC campaigns, remember to consider all expenses in your total cost, including:

  • Ad spend: Ad spend includes the costs of advertising on Google Ads, Facebook, or any other search engine or social media platform.
  • Technology costs: Account for any technology you’re using to build and optimize your ads. This includes platforms like SEO or PPC software, design software, and keyword tools.
  • Labor costs: You may want to include the cost of the employees needed to develop and administer your PPC campaigns. If so, make sure to add in the costs associated with their time.
  • Third-part costs: If you’re using a digital marketing agency to assist with your PPC campaigns, or you’re using an independent contractor, you’ll want to account for these expenses, as well.
    These expenses will affect both your total revenue and the total cost of your paid campaigns when calculating ROI.

The easiest way to calculate PPC ROI is with the following equation:

Google estimates that for every $1 spent on a PPC campaign in Google Adwords, businesses earn an average revenue of $2.

Calculating ROAS

Different than ROI, ROAS (return on ad spend) calculates how much revenue was earned for every dollar spent. A good rule to start with is to aim to break even, and then optimize from there. It’s important to understand your break-even point and to set that as a minimum goal to avoid losing unnecessary amounts of money. The break-even point for ROAS is 1:1, which means that for every $1 spent on advertising, you should earn $1 in revenue.

ROAS can be calculated as a percentage, using the following formula:

Calculating Profit Per Click

In order to measure your PPC campaigns’ ROI, it’s necessary to track the conversions points, or the actions viewers take on your website after seeing an ad. Common examples of conversions could be filling out a form, calling your business, downloading a whitepaper, or making a purchase. You can use Google’s free conversion tracking tool to understand what happens after a customer interacts with your ads.

The value of each conversion should be greater than the amount spent to get the conversion. To calculate profit per click, simply divide the total profit by the total number of clicks. For example, if you spend $20 on 5 clicks to get one sale and receive $30 for that sale, your profit per click would be $6. This calculation is a good indication of where the click revenue is coming from.

Leverage Digital Advertising Analytics to Improve ROI

All three of these formulas can be effective ways to measure the success of your PPC campaigns. By tracking these digital advertising analytics, you can better understand your target audience and their search behavior as well as be better positioned to optimize your ads and identify where to increase or decrease your budget for certain campaigns.
