eCommerce PPC Management: 5 Metrics You MUST be Tracking

eCommerce PPC management

Let’s face it. The internet has created a lot of self-proclaimed “digital marketing experts” that probably still use a flip phone and wish they could make Netscape Navigator their default web browser (Okay, that’s probably a stretch but you get my point). When it comes to digital marketing, in particular, eCommerce PPC management, who are you going to trust? Some self-proclaimed “expert” cranking out blogs in his basement or an actual expert that manages eCommerce PPC campaigns day in and day out for a portfolio of clients?

Think about it this way…if you need a knee replaced, who would you want to perform your surgery? A world-class surgeon that’s performed more knee replacements than they can count or a first-year resident that may or may not know their #10 blades from their forceps? (If you’re of sane mind, I’m going to assume you chose the former!)

While there’s a TON of content out there about how to build and measure an effective eCommerce PPC campaign, most of it is not reliable. Any Joe Schmoe can tell you how to execute a campaign but does Mr. Schmoe really know what KPIs (key performance indicators) matter and how to drive results? No offense to Joe, but probably not.

To help you combat all of the misinformation out there, we put together this guide that outlines the 5 KPIs you MUST be tracking as part of your eCommerce PPC management strategy. These aren’t your run-of-the-mill metrics like impressions, clicks, etc. These are the key performance indicators our own team of PPC experts use to drive revenue for our hundreds of successful eCommerce clients.

Think of this as your sneak peek behind the curtain of a leading eCommerce PPC agency. No Joe Schmoes here!

So without further ado, let’s dive in!


Why You Shouldn’t Use Conversion Value As Your Primary KPI

Before we get into the nitty-gritty about the metrics that are most indicative of your PPC campaign’s success, we wanted to debunk a common misconception about conversion value.

For many, conversion value is seen as the primary KPI that speaks to the overall success of your PPC campaign, but that can be incredibly misleading if not looked at in context. At the end of the day, conversion value only measures how much you’re making without taking into consideration how much you’re spending.

Sure, that’s great if you made $1,000,000 but not if you spent $2,000,000. I’m no accountant, but an ROI like that wouldn’t look so great to your CFO.

Bottom line: conversion value should ABSOLUTELY NOT be used as your primary KPI when it comes to your eCommerce PPC efforts.

The 5 Most Critical KPIs For Your eCommerce PPC Campaign

Now that we’ve debunked that common myth, let’s get into the five KPIs you should be laser-focused on:

  • Conv. Value / Cost
  • Conv. Rate
  • Cost / Conv.
  • Value / Conv.
  • Price Competitiveness

Conv. Value / Cost

Conversion value per cost (“Conv. Value / Cost”) is what our team considers to be the MOST valuable KPI as it helps show how profitable each area of your account is and how well you’re tracking overall. THIS is the bottom line: ROI.

Conversion value per cost is calculated by dividing your total conversion value by your total cost (aka ad spend).

Take the below as an example. Here, our total conversion value is $255,000 and our total cost (ad spend) is $35,300.

Conversion Value

So we take $255,000 / $35,300 = $7.21

Basically, this is telling you that for every dollar you spend on advertising, you’re earning $7.21 back. This is one of those instances where more is most definitely better. The higher your conversion value per cost, the more revenue you’re driving. Pretty straightforward, right?

Conversion value per cost is a great, hard-hitting KPI to share with your leadership team as it boils down to how profitable (or unprofitable) your PPC campaign has been.

Conv. Rate

While ad clicks and video views are nice, your CEO isn’t going to give a damn about them unless they’re driving revenue. That’s where your conversion rate (“Conv. rate”) comes into play.

Conversion rate refers to how frequently a click on your ad turns into a conversion. It is calculated by taking your total number of conversions divided by your total clicks (or other interactions like video views).

In our example below, we have (rounding up) 241 conversions and 14,600 clicks so we take 241 / 14,600. This gives us a conversion rate of 1.65%.

Conversion Rate

On average, eCommerce conversion rates are in the 1-3% range but that varies widely by industry so you’ll want to benchmark yourself against players in your own sector to gauge true performance.

Improving conversion rate is more of a science than art, involving A/B testing your ad copy, creative, and landing pages. Your conversion rate is wildly important to your overall eCommerce PPC management strategy so if you’re at a loss on how to improve it, it’s often best to engage a Google Ads agency (we may know of one that can help 😉).

Cost / Conv.

Next on the list of KPIs to track is the cost per conversion (“Cost / Conv.”). We like to think about cost per conversion as how much you need to spend before you see a conversion. In a nutshell, it’s a way to look at the average cost for each conversion.

To calculate cost per conversion, just take your total cost (ad spend) and divide it by your total conversions.

Ready for some more math?

Using the example below, we’ll take $35,300 (cost) / 241 (conversions).

That gives us a “Cost / Conv.” of $147.

Cost Per Conversion

Cost per conversion is something you’ll want to track over time and use as a metric to help inform your campaign budgets. Of course, several factors will come into play but having a solid understanding of your cost per conversion will help tremendously for planning purposes.

Value / Conv.

Still with me? Just a couple of more KPIs to get through, I swear!

As you [hopefully] already know, a solid bid strategy is essential when it comes to eCommerce PPC management and that is why value per conversion (“Value / Conv.”) is so critical. When determining how much to bid, you MUST look at your value per conversion metric. It is an absolute must.

Value per conversion shows on average how much a conversion is worth.

This metric is calculated by taking your total conversion value divided by your total number of conversions as noted in the below formula.

“Conv. Value” / “Conversions”

Let’s say you have a conversion value of $100,000 and 4,000 conversions. Your value per conversion would be $25 ($100,000 / 4,000 = $25).

We like to look at value per conversion in conjunction with cost per conversion (“Cost / Conv.”). If you only make $25 with each conversion, and your “Cost / Conv.” is $20, you are significantly eating into your margins – and that is never a good thing.

The good news is that scenarios like the above can be avoided if you know what metrics to track (Phew, you can exhale a sigh of relief now!).

Based on your “Value / Conv” and your “Cost / Conv.,” you can scale your bids up or down to remain as profitable and competitive as possible. If you’re not sure where to begin when it comes to your eCommerce PPC bid strategy, you can always ask our PPC experts to give you an assist.


Price Competitiveness

And last but not least (drumroll, please)….we have price competitiveness!

Price Competitiveness is a new entry in Google Merchant Center, which helps you analyze how your price compares to your competitors. Pretty, sweet, huh?

Our team uses price competitiveness to understand which auctions they have a better chance of winning. The report is accessible via your Google Merchant Center account (just navigate to the “Growth” tab then click “Price competitiveness”). Once you’re in the report, you’ll have the option to group your information by product, product type, category, or brand.

You’ll then see a breakdown (see example below) of how your products rank when benchmarked against your competitors. As our eCommerce PPC team will tell you, these kinds of insights are pure gold! In a few simple clicks, you have direct insight into which of your products are price competitive, which in turn tells you where you can (and should) raise your bids.
