Many businesses do everything possible to convert their website users into real customers, but more than half of companies don’t pay enough attention to their sales funnel and lose valuable opportunities after all the upfront sales and marketing efforts.
Conversion rate optimization (CRO) aims to increase the number of internet visitors who take your desired action. “Desired action” can refer to signing up, subscribing, completing a form, or clicking “add to cart”.
One proven strategy is to hire a professional to help optimize your sales funnel to stop leaks and keep nudging those leads toward the final purchase!
In this post, we have selected and reviewed the top CRO agencies. We also cover the services CRO agencies offer and the benefits of CRO for your business.

There are various strategies and best practices that marketers use for CRO.
A/B testing describes testing variables against each other to determine which performs better.
For example, to determine which landing page to use, marketers create one with a discount and another with free shipping. They then run an experiment by comparing them to find out which drives better results, i.e. click-through rate in this case.
A/B testing is necessary for CRO to determine which strategies work and which don’t.
It gives businesses a clear direction to improve their conversion rates and direct resources to the methods that provide the most value for money.
Multivariate testing works similarly to A/B testing. However, unlike A/B testing, which involves testing entire pages against each other, multivariate testing involves testing smaller sections of the pages.
For instance, to evaluate which elements will drive the highest conversion rates, marketers can test the performance of two different headlines for one page.
Professionals can do this while evaluating another set of two different headlines for a second page.
They can also test the entire two pages with their headlines against each other for the ultimate results.
When analytics is done right, this approach can achieve your desired results faster, as multiple tests can occur simultaneously.
The LIFT model is a popular CRO framework. This framework reveals six vital conversion factors, allowing you to test landing pages from the perspective of your web visitors.
The LIFT model is the theory behind A/B and multivariate testing. Using the LIFT model, marketers can conduct a hypothesis and then test it using A/B and multivariate testing.
The six conversion factors expressed in the LIFT model are:
Here are the top factors to evaluate for choosing a CRO agency:
We spoke about CRO frameworks and best practices. While methods like A/B testing and the LIFT Model are vital, opt for a CRO agency with custom frameworks. This proves the agency has enough experience and understanding of this environment to design its own frameworks and processes they know will drive results.
What past clients have to say about a CRO company matters. Check a CRO agency’s Google ratings and social media to confirm that the company is legitimate. The proof is in the pudding, and this is no different for agencies. So, you should also request result-based testimonials from the agency to confirm their expertise.
Successful CRO relies on in-depth data and website analytics. Your agency must use data-backed strategies for CRO. They should ask loads of questions about your web analytics, Google Analytics and so forth. If an agency doesn’t seem to consider data, then you don’t consider them!
Agencies aren’t cheap. Pick an agency that offers quick, helpful customer support. If things go wrong, you don’t want to be stuck with problems you can’t solve. Check the agency’s reviews to find out how well their support is. Remember, you’ll pay quite a price for CRO services, so you need premium support.
CRO agencies aren’t digital marketing agencies. However, they must know how different marketing channels work to optimize your performance and connect with audiences on each marketing channel. So, if your business relies on Instagram for web traffic, your agency must know everything they can about Instagram.
If your agency has well-known professionals on its team, that’s a huge plus. If not, ensure the agency has extensive experience working with businesses like yours and a good handle on CRO best practices. Check their portfolio to see their experience with brands like yours and whether the agency has enough experience for what you need.
Instead of struggling with your sales funnel drop-offs, hire an agency that specializes in conversion optimization.
These specialist firms have the expertise, experience, and technical expertise to offer a wide range of marketing services implemented using data-driven strategies to your advantage.

It is the strategy of increasing the number of web visitors who take a business's desired action.
