What Is Conversion Cost and Why Does It Matter?

As a business investing in digital marketing and advertising, one of the most important metrics to track is your conversion cost. Put simply, conversion cost is the amount of money you have to spend on average to generate a single conversion.

A conversion can mean different things depending on your business goals and the specific campaign, but common examples include:

A completed purchase on your ecommerce site
A new lead or email subscriber
A free trial sign-up for your SaaS product
An app install or in-app purchase
A content download like an ebook or whitepaper

Essentially, a conversion is any desired action you want your prospects to take after engaging with your marketing. And conversion cost gives you a straightforward way to measure the return on investment for your campaigns.

How to Calculate Conversion Cost

The formula for conversion cost is simple:

Conversion Cost = Total Ad Spend / Number of Conversions

For example, let‘s say you spend $5,000 on a Facebook ad campaign in a month and it generates 250 ebook downloads. Your conversion cost would be:

$5,000 / 250 = $20 per ebook download

This means you‘re spending $20 to acquire each new ebook lead on average. Whether this is good or not depends on the context of your business and industry. A $20 cost per lead would be very profitable for a high-ticket B2B software company, but very unprofitable for a low-margin ecommerce business.

Conversion Cost vs ROAS and CPA

Conversion cost is closely related to two other important marketing metrics:

Return on Ad Spend (ROAS) – This measures the revenue generated per dollar spent on advertising. The formula is: Revenue / Total Ad Spend. A ROAS of 5 means you generated $5 in revenue for every $1 in ad spend.
Cost Per Acquisition (CPA) – Similar to conversion cost, but focused specifically on the cost to acquire a new paying customer, rather than just a lead or other conversion event. CPA matters more for judging the bottom-line profitability and ROI of your marketing.

You can use these related metrics along with conversion cost to get a more complete picture of marketing performance. If conversion costs are low but ROAS and CPA are also low, it means you may be driving cheaper conversions but not ones that are translating into revenue for the business.

Key Factors That Affect Conversion Cost

Many different variables can impact your conversion costs, which makes it a metric you have to monitor and optimize continuously. Some of the biggest factors include:

Conversion Point – Are you optimizing for top-of-funnel conversions like email sign-ups or bottom-of-funnel conversions like demos and purchases? Higher-intent conversions more closely tied to revenue will typically have higher costs.
Audience Targeting – The more relevant your audience targeting, the better your conversion rates will be. But if you target too narrow of an audience, you may end up paying more due to increased competition. It‘s all about striking the right balance.
Ad Creative and Copy – Your ads themselves, including headlines, visuals, offers and calls-to-action play a huge role in conversion rates and costs. Small tweaks can often lead to significant improvements.
Bidding Strategy – On platforms like Google and Facebook Ads, your bidding strategy impacts what you pay for clicks and conversions. Strategies like target CPA and maximize conversions can help control costs.
Landing Page – The post-click experience has to match the pre-click experience and effectively convince visitors to convert. Poor landing page experiences will tank conversion rates.
Seasonality and Competition – When competition and demand increase, like around the holidays for many consumer brands, conversion costs typically rise as well. Your costs will rarely stay stable month-to-month.

8 Tips to Reduce Conversion Costs

If your conversion costs are higher than you‘d like, don‘t worry. There are many levers you can pull to bring them down over time, such as:

Institute conversion tracking – You can‘t optimize what you don‘t measure. Make sure you have proper tracking in place to measure conversions and associated costs.
A/B test ads and landing pages – Experiment with different creative variations, copies, offers, and designs to see which combinations lead to higher conversion rates and lower costs. Always be testing!
Improve audience targeting – Analyze your customer data and conversion paths to identify your highest-value audience segments. Refine targeting to focus more on these high performers.
Test bidding strategies – Don‘t just set and forget bids. Explore different strategies like cost-per-click, enhanced cost-per-click, target CPA, and more to optimize for your goals.
Leverage remarketing – People who have engaged with you before will be more likely to convert. Use remarketing across channels to bring back interested prospects.
Improve website experience – Make sure your website and landing pages provide an excellent user experience on every device. Poor experiences will destroy conversion rates.
Offer compelling lead magnets – Give people a good reason to hand over their contact information. Create valuable gated offers like ebooks, webinars, calculators and more.
Increase average order value – Getting more value from each converting customer will offset acquisition costs. Use upsells, cross-sells, bundles and more to drive up AOV.

Conversion Cost Industry Benchmarks

To put your own conversion costs in context, it helps to know average benchmarks for different marketing channels and industries. Here are a few key ones to be aware of:

Google Ads search – Average conversion cost of $56 with conversion rate of 4%.
Facebook Ads – Average conversion cost of $18 with conversion rate of 9%.
Instagram Ads – Average conversion cost of $20 with conversion rate of 2%.
LinkedIn Ads – Average conversion cost of $65 with conversion rate of 6%.
eCommerce – Average conversion cost of $45-$55
SaaS – Average conversion cost of $100-$150 for a free trial sign-up
B2B – Average conversion cost of $150-$200 per lead

However, keep in mind these will vary widely depending on your specific niche, product price points, targeting, and more. Use them as loose benchmarks but not absolute measures of success.

Tools to Track and Analyze Conversion Costs

To effectively measure and optimize your conversion costs, you‘ll need the right tools and analytics in place. Some of the most essential include:

Google Analytics – The free website analytics tool can track important engagement metrics, traffic sources, conversions, and more.

Most of the major advertising and analytics platforms have their own conversion tracking and attribution modeling capabilities. Take advantage of them to centralize your data and make it easy to gauge performance.

How to Use Conversion Cost Data

Having the conversion cost data is just half the battle. To actually improve your marketing results, you need to analyze the data and use it to make informed optimization decisions. Here are a few ways to do that:

Compare costs across different channels to see which are most efficient at driving conversions. Double down on your top performers.
Analyze conversion paths to understand the key touchpoints and messages moving people towards conversion. Emphasize these in your campaigns.
Look at conversion costs over time to understand seasonality and benchmark your improvement. Aim to maintain or decrease costs month-over-month.
Feed conversion data into lifetime value projections to determine your target cost per acquisition. Optimize towards maximizing long-term customer value.

Conversion Cost Case Studies

To see the impact conversion cost optimization can have in the real world, let‘s look at a couple of quick case studies.

The first comes from Logical Position, a digital marketing agency specializing in paid search and social. They worked with a large automotive parts ecommerce client to reduce conversion costs.

Through a combination of refining keyword targeting, A/B testing ad copy, and optimizing for ROAS bidding, they were able to:

Increase conversion rates by 236%
Decrease cost-per-conversion by 64%
Drive a 271% increase in revenue

The second case study is from Disruptive Advertising and involves a large furniture ecommerce company.

Disruptive helped the company:

Build out detailed Analytics tracking to get clearer conversion data
