Are you a start-up aiming to become a unicorn? Are you looking for a way to achieve hockey stick growth for your business?

In order to achieve those ambitious goals, it is more than essential that you understand your customers.

One of the best ways to understand your customers is to find out how they behave: what makes them do or not do something online?

To find that out, you should look into conversion rate optimization.

This blog will help you understand the biggest conversion rate optimization benefits and show you how to create a CRO strategy using social proof in 3 easy steps.

Let’s go, CRO!

What Is Conversion Rate Optimization?

Conversion rate tells you the percentage of people who performed the desired action (aka conversion event) on your website or other online content.

Conversion rate optimization (CRO) is the process of trying to increase the conversion rate.

In practice this means that you need to study what makes people perform the conversion events, and what prevents them from performing those. Based on that information, you make changes that increase conversions, like in the example below where a simple color change had a significant effect:

For a more in-depth definition of conversion rate and other related terminology, see the Definitive Guide to Optimizing Conversion Rate.

13 Biggest Benefits of CRO

The biggest CRO benefits include the following 13 aspects. Start optimizing your conversion rate today, and soon enough your business will reach these results.

1. More Leads and New Customers

When your website visitors are likely to stay on your website for a longer period of time thanks to the conversion optimization you have been doing, you can generate more leads and acquire more customers.

The next logical outcome to having more customers is getting more sales and more money. Yay!

2. Increased ROI on Paid Advertising

When you get more conversions through your paid advertisements, the ROI increases and you get your money’s worth of traffic and transactions.

3. Lower Customer Acquisition Costs

The number of conversions you get in exchange for certain investment defines your customer acquisition cost. The more you convert, the lower the cost.

4. Minimized Bounce Rate

I hate it when websites don’t work properly, or if they are difficult to navigate. In case I encounter websites like that, I will willingly just move my business somewhere else. And I am not alone: the average bounce rate is around 50%

This of course depends on your industry, but if you are able to keep over half of your site visitors browsing your pages, you are doing well! And if you are not doing that well yet, CRO helps you lower the number.

5. Improved Digital Customer Experience

If people are enjoying your website, find their way around your landing pages and like the design, they are happier with the experience. Happy customers tend to visit your site again.

6. Learn More About Your Customers

In order to gain deeper understanding about your customers and how CRO might affect them, you should create buyer personas who imitate your target audience and help you figure out what they really want.

Once you test out different solutions, you simultaneously learn more about your paying customers and can further improve the customer journey.

7. Increased Customer Lifetime Value

If your online store is easier to navigate and use than your competitor’s, or if your website has more perceived value, the customer will be more likely to come back again. This means that over time they will purchase multiple times from you and grow customer lifetime value.

8. Maximum Benefit from the Marketing Budget 

If your marketing efforts bring lots of traffic to your website and your CRO process makes sure that the traffic results in conversions, you have successfully maximized the potential of your marketing campaign.

9. More Visibility in Search Engines

If you are able to minimize your bounce rate and keep your customer on the website longer, you will reach better search engine results.

10. More Website Traffic

Because of the increased visibility in search engines, you will get more traffic on your web pages.

11. Stay Ahead of Your Competitors

When you are actively doing CRO testing, you can notice changes in user behavior and react to them fast, which might possibly get you ahead of your competitors.

12. You Make More Educated Decisions

When your decisions are based on hard data rather than just intuition or “hunch”, you can be more confident about taking risks and experimenting with different solutions.

13. Overall Higher Revenue and More Profit

If we look at all the benefits listed above (in a nutshell: increased conversions and decreased costs), they will result in higher revenue and more profit.

Create CRO Strategy Using Social Proof in 3 Easy Steps 

When you start your CRO efforts, you want to know what would make your site visitors perform the desired actions such as making a purchase, requesting a quote, booking a demo or starting a free trial.

Let me tell you that social proof is extremely beneficial in conversion rate optimization.

Social proof refers to the psychological phenomenon that makes people act and think like their peers.

If your prospective client is just about to convert, and they see a review or testimonial from a previous happy customer, that might be just the push that they need to make the decision.

Now, let’s discuss how you can create your own CRO strategy utilizing social proof.

Step #1: Adopt Trustmary to Collect Social Proof

  • Collect testimonials and reviews (=social proof)
  • Showcase the testimonials on your website
  • Set automations for the process

Step #3: Do A/B Split Testing

After you have implemented the previous steps, you can start tracking which testimonials work best on your website and on your target audience.

Over time you will start noticing that some testimonials convert better than others. And I would bet that video testimonials like the one below make a great impression on your potential customers!
