7 Benefits of Conversion Rate Optimization

Businesses often point to web traffic as an indicator of success. To be clear, attracting thousands of daily visitors to a website is a notable achievement.

However, more traffic doesn’t necessarily translate to more sales. If only a tiny fraction of potential customers are taking the desired action—say, filling out a lead generation form or completing a purchase—the total number of visitors is irrelevant.

To increase the percentage of visitors who reach the end of the funnel, brands turn to conversion rate optimization (CRO). More than just driving traffic, CRO allows businesses to extract more value from each existing visitor.

In other words, CRO strategies make every click count. And that’s just one of the benefits of conversion rate optimization.

CRO is the art and science of guiding website visitors toward a predetermined goal. (In most cases, that goal is a purchase.)

Successful brands leverage several CRO strategies to increase the rate at which consumers follow through. These strategies include:

When executed correctly, CRO is a comprehensive, iterative approach to website optimization that encompasses consumer behavior analysis, frequent A/B testing, and more.

To the untrained eye, the never-ending efforts of CRO may seem excessive. Is the juice really worth the squeeze?

It sure is.

Marketing experts and brand leaders agree that CRO is a critical component of any performance marketing or growth strategy. Because customers only generate revenue when they reach the bottom of the funnel, any approach that moves them swiftly through that funnel is invaluable.

So, without further ado, here are seven benefits of conversion rate optimization.

In nearly all cases, driving more traffic means paying more. Whether it’s increasing the budget for paid social media ads or partnering with a well-known influencer, brands typically have to spend money to make money.

With a well-thought-out CRO strategy, businesses can escape this “pay to play” cycle. That’s because CRO allows for the generation of more sales, leads, or sign-ups from the same audience.

Put differently, CRO is the most efficient way to earn more. It’s a sustainable, quality-over-quantity approach that focuses on converting more of the visitors who already exist, rather than paying for more visitors (who may not buy anything).

What’s more, increasing revenue without increasing traffic offers a secondary benefit: infrastructure savings. As web traffic increases, businesses usually have to pay for improved hosting solutions with more bandwidth. By making the most of existing traffic first, companies can keep their website costs low.

Return on investment (ROI) is the gold-standard metric for revenue-generating marketing teams. Return on ad spend (ROAS)—a subset of ROI—is even more crucial to keep an eye on.

As it turns out, CRO plays an oversized role in increasing a brand’s return on its marketing investments. Even a small lift in conversion rate can significantly improve ROAS for paid media, SEO, and email.

Imagine an Instagram ad campaign with the following performance metrics:

In this scenario, 100 of the 5,000 visitors completed the desired action (purchasing), so the conversion rate is 2%. The total ROAS for this campaign ($10,000 in ad spend divided by $10,000 in sales) is 1, which is the break-even point.

Now, imagine a second scenario with a slight increase in conversions. If 120 visitors complete a purchase—just 20 more—the new conversion rate is 2.4%.

Though an increase of 0.4 percentage points may seem minor, the impact on ROI is profound. With $12,000 in revenue from the same $10,000 ad spend, the new ROAS is 1.2—a 20% increase.

Ultimately, the compounding power of increasing CRO makes any effort put into marketing optimization well worth it.

Naturally, the benefits of conversion rate optimization go beyond the financial.

Many CRO strategies revolve around reducing user friction. From simplifying menus to making the search function more approachable, there are endless ways to make it easier for customers to reach the finish line. 

All this streamlining is a win for both brands and their supporters.

When businesses improve the overall user experience, site visitors enjoy several advantages, including:

The brand, meanwhile, reaps the rewards of this improved experience. Visitors are likely to spend more time on a nice-to-use website, which signals to search engines that the content is valuable (and worth ranking higher).

What do all top brands have in common? They offer the kind of experience described above: A fast, user-friendly website with clear messaging.

This commonality is no mistake. Through CRO, the biggest brands create a sense of credibility. That’s because consumers are more likely to trust a well-maintained site than an unreliable one. In fact, 67% of consumers won’t continue buying from a brand if they don’t trust it.

With this statistic in mind, many businesses focus on a more overt form of trust-building CRO: social proof.

Social proof (which includes customer testimonials, industry awards, and “clients we’ve worked with” sections) tells shoppers they’re in good hands. Known as trust signals, these website must-haves make visitors feel more comfortable converting—because they know they’re not alone.

And because trust ultimately leads to loyalty, this benefit of CRO can’t be overlooked.

Through analysis—a cornerstone of optimization—CRO also reveals how users behave, what resonates with them, and where they get stuck.

Brands use a variety of analytics tools and strategies to understand their customer base, such as:

The data from these tools shows companies how to better convert site visitors. But that knowledge is only the tip of the iceberg.

An understanding of customer preferences is remarkably valuable. Visitor insights can inform everything from product development to future marketing campaigns.

Customer acquisition cost (CAC) is a vital business metric that defines the total cost of gaining a new brand supporter.

CAC is calculated by dividing total sales and marketing expenses by the number of new customers acquired. For instance, if a brand spends $10,000 and acquires 100 new customers, the CAC is $100.

The average CAC depends on the industry, as demonstrated below:

Regardless of industry, brands can decrease their CAC—and stretch advertising budgets—by increasing their total number of conversions. Using the same math, a $10,000 campaign that converts 250 site visitors has a CAC of just $40.

Thanks to all the benefits above, CRO is the gift that keeps on giving. While it may take some trial and error (and plenty of time) to optimize a site for conversions, those hours are well-spent.

Why? Because CRO provides a strong foundation for scaling.

The more optimized a brand’s funnel is, the easier it becomes for them to invest in traffic-driving tactics. In other words, when the accounting team sees that current ad spend is delivering better results, they’re far more willing to up the campaign budget.

After all, CRO efforts don’t disappear. They compound over time, allowing companies to grow faster and faster without reinvesting in the same strategies.

If your brand isn’t leveraging conversion rate optimization to its full potential, you’re missing out on the benefits. CRO improves marketing effectiveness, customer satisfaction, and business performance—all for a minimal capital investment.

But make no mistake: CRO isn’t a one-time fix. It’s an ongoing strategy that requires endless testing and adjustments.

Fortunately, the effort is beyond worthwhile. By prioritizing optimization alongside traffic generation, your brand can enjoy sustainable, high-impact growth.
