According to Google, an average CPA is defined below-

“The price advertisers pay for every new customer they acquire, which is calculated by dividing the total cost of conversions by the number of conversions. Google determines the CPA based on your quality score.”

CPA means ROI of a campaign and reducing it will make more return for your PPC investment.

A low CPA is always favouring the advertiser’s interest to find more leads for less investment. Although an average CPA vary industry-wise.

There is a lot of variation between industries, so you should remember the value of you and your client’s conversion while reducing CPA.

Ways to Reduce Your CPA

#1 Strategically Target the Location

Location is quite important for successful PPC activities.

Suppose you set targeting location broad in Google Ads, there might be chances that you gonna serve them to poorly-converting regions.

These are the locations which haven’t performed over the last few months and hardly generated any conversion.

Go to Google Analytics to see if you’ve set Google Ads broad targeting and spending a lot of money.

Go to Audience > Geo > Location.

After reaching Google Analytics, you’ll see Sessions dropdown list available in the top left corner.

From the list, choose Conversion Rate inside Goal in order to find which are the most successful regions as well as which are not in terms of conversion.

Once PPC advertisers come to know which location is giving them the best profit, they can save their money.

This way you can effectively reduce your CPA and improve your campaign’s ROI.

#2 Focus on Quality Score with Defined Ad Structure

An advertiser’s quality score also matters when it comes to reduce CPA.

So, every marketer should improve his or her quality score.

It has been seen that if you optimize your quality score then that optimization result also helps to reduce CPA.

With years of experience, an advertiser certainly tries to improve quality score with factors like relevancy.

However, in the never-ending quest to improve quality score, campaign managers can sometimes ignore the importance of a clean ad structure.

This helps you improve your CTR and hence quality score.

SKAGs (single-keyword-ad-groups) is an ad structure that helps advertisers focus on only one keyword per ad group.

It should be noted that only make SKAGs for your best performing keywords and Google Analytics will help you know that.

#3 Employ Google Ads ‘IF Functions’

Google Ads “IF functions” have proved to be helpful for PPC marketers.

These functions enable marketers to set rules for their ads to present them in desired conditions.

Rules are like- “Only show my mobile ad IF the user is using a mobile device as shown in the examples from Google below.”

Putting rules in ads helps paid search marketers in two ways-
  • Rules applied to ensure that the ads are relevant enough to make users click. Improving CTR would lead to enhanced quality score thus reducing CPA.
  • Making ads useful and targeted to the user ensures you won’t have to pay for irrelevant clicks. This will also reduce costs.

To begin using IF Functions in Google Ads first ask yourself what part of your ad could be optimized.

If you’re going to use IF Functions in Google Ads, first try to know which ad part could be optimized.

Is it Audience or Pricing or Ad copy?

Then get to work experimenting and iterating on your results.

Then go for optimizing it relevantly for the users. Ongoing optimization is an assured way to minimize costs in paid search marketing.
