    What is Conversion Rate Optimization (CRO)?

    CRO is a marketing technique to increase the number of web visitors who take your desired action. “Desired action” can refer to signing up, subscribing, completing a form or clicking, “add to cart”.

    When your conversion rate is low, you need to evaluate certain factors. This includes what encourages users to your site, drives them away from your site, or persuades them to take your desired action. Understanding this makes it easier to implement CRO strategies that work.

    Summary: What is Conversion Rate Optimization (CRO)? 

    CRO is a marketing technique to increase the number of web visitors who take your desired action. “Desired action” can refer to signing up, subscribing, completing a form, clicking “add to cart” or “buy now”.

    What Services Do Conversion Rate Optimization (CRO) Agencies Offer? 

    To ensure your website generates the conversion rates you want, conversion optimization agencies have a ton to offer, including the following common CRO services:

    Data Analysis

    If you’re not a fan of statistics, you’ll be glad to know that CRO agencies help with all aspects of your data and analytics.

    Your agency should meticulously analyze all the data you provide them with. If needed, the agency needs to configure or re-configure your analytics tools to present accurate and consistent data.

    Without consistent data, neither you nor the agency can perform a successful CRO strategy, so this is crucial. Also, the key to a customer-centric strategy will be your data. It’s just as important to discuss the metrics that are essential to you, and determine the primary focus from the beginning stage.

    Pro Tip

    Pick only one metric to focus on in the beginning. Once you accomplish your initial goal, you can move on to the next metric. For instance, focus on the conversion rate from visitors to add to cart. After that, focus on the conversion rate from add to cart to the payment process.

    Conversion Rate Optimization (CRO) Strategy

    Your agency will undoubtedly conduct a CRO strategy for our business. This strategy should include detailed documents on your CRO process, and spreadsheets of experiments that you and the agency will execute to achieve your essential metrics.

    Regular Reporting

    Your CRO agency needs to provide you with weekly or monthly reports. This is essential as you need to understand how the agency is helping your business, and if you’re getting closer to your objective. Without regular reporting, you’ll have little way to determine your progress and the quality of the agency’s services.

    Development & Design

    A professional agency will have the expertise to modify or create visually appealing web pages for your website. This is essential for experimentation, so ensure that your agency does have a proven track record of web development and design.

    You can get an idea of your agency’s web development and design work by looking at their portfolio. Doing this will give you an accurate idea of the templates they use, and whether they understand what a high-converting website looks like.

    Copywriting

    Several CRO experiments will require seasoned copywriting skills. Ensure that your CRO agency can provide this, so you can receive optimal results from your content marketing. Through copywriting, your agency should be able to capture your brand’s voice and connect with your ideal audience.

    What Do CRO Agencies Do for Businesses?

    CRO agencies develop and implement CRO strategies for businesses’ websites. These agencies work with businesses of all shapes and sizes, to help these brands:

    • Run marketing experiments to define authentic methods to boost conversion rates.
    • Perform A/B testing on marketing experiments and strategies to determine the most valuable and results-driven methods.
    • Gather customer feedback to enhance your current processes through user interviews, surveys, polls, questionnaires, etc.
    • Use qualitative data from A/B testing, buyer feedback, and marketing experiments to establish SMART goals, key metrics, and benchmarks.

    CRO agencies have the teams, tools, and expertise to help businesses optimize their conversion rates. They take strategic approaches to gather an in-depth analysis of your audience, and what drives these buyers to conversion. Your agency will uncover insights about your audience to optimize your CRO.

    These insights include:

    • Your top-performing marketing channels.
    • Bottlenecks and challenges in your buyer’s journey.
    • Your social sentiment, meaning how your target customers feel about your brand.
    • Your best and least performing buyer segments.

    With the help of CRO agencies, you can gather a robust understanding of what drives buyer behavior and trends, and how you can leverage this to accelerate revenue. 

    Benefits of CRO: 5 Advantages of CRO Agencies for Brands

    There are many advantages that conversion optimization agencies offer. For starters, you can understand in-depth insights about your audience and boost your website.

    CRO agencies will also help you lower your buyer acquisition costs and increase your customer lifetime value. Plus these agencies can take your reputation to the next level too!

    Let’s explore these top benefits of CRO agencies. 

    1.Understand Your Buyers First-hand

    The more you know about your target audience and what they look for in businesses, the easier it is to drive sales and customer engagement. CRO agencies allow you to discover in-depth insights about your buyers’ trends, purchasing behavior, and buying pain points. You’ll understand every touchpoint of your buying journey and overall product experience (PX). 

    Businesses can use this customer data to:

    • Personalized their web design and marketing efforts to their target audience.
    • Determine fresh marketing approaches that address buyers’ pain points.
    • Optimize their PX so customers get maximum value.
    • Create buyer-centric upselling and cross-selling strategies.

    2.Improve Your Website Performance

    While there’s no such thing as a perfect website, every fault in your design and usability gives web visitors a reason to exit your website. Businesses must have brand-centric, functional websites with easy navigation. The second web visitors land on your website, they should know who your business is, your value proposition and why you matter to them.

    Using robust data, CRO agencies will find ways to optimize your website performance and use your existing organic traffic. When we say “use your existing organic traffic”, we mean exactly that.

    You don’t need to garner brand-new website visitors. Instead, CRO agencies will analyze your current web traffic to find ways to boost your website and overall deliverability.

    3.Boost Your Brand Reputation

    When CRO agencies use conversion rate optimization strategies to improve your customer journey, optimize your PX and understand your buyers, this shows a lot of customer appreciation. Consequently, it will be easier for your business to establish a positive brand reputation among your target audience.

    Why wouldn’t your buyers love a business that puts them first?

    CRO isn’t only about maximizing your revenue. This practice aims to make it easier for buyers to find value in your brand and see how you can achieve their goals and reap all the benefits from your products/services. With this user-centric approach, businesses can keep their customers satisfied and prove to them that they matter to their brand.

    Also, CRO practices make open opportunities to secure credibility and authority. Professionally-designed and branded websites always make businesses look more trustworthy. 

    4.Lower Customer Acquisition Costs

    Your customer acquisition costs evaluate how much it costs to secure each new customer. CRO agencies that aren’t full-service won’t manage and boost your marketing campaigns.

    However, the services they offer and the insights they gather will highlight the top solutions to keep your customer acquisition costs as low as possible.

    Remember, CRO marketing agencies help businesses understand what their customers what and the best ways to achieve this.

    When you use this information to optimize and eliminate revenue streams, develop a user-centric website and boost your brand reputation, acquiring customers will be easier and less costly.

    From all these efforts, you’re more likely to attract organic traffic. And for paid marketing channels, you’re more likely to drive targeted buyers that will convert.

    5.Increase Customer Lifetime Value

    Your customer lifetime value (CLV) evaluates how much each customer spends in their entire time purchasing from your brand. As I mentioned, a key part of CRO agencies is to help you identify and understand your target audience.

    With this analysis come opportunities to find conversion rate optimization strategies that persuade buyers to spend more money on each visit.

    Just as expert agencies can lower customer acquisition costs through user-centric websites, optimized buying journeys, and an improved brand reputation, they can help accelerate your CLV.

    Summary: The Advantages of a CRO Agency

    1. Understand Your Buyers First-hand
    2. Improve Your Website Performance
    3. Boost Your Brand Reputation
    4. Lower Customer Acquisition Costs
    5. Increase Customer Lifetime Value

    How Much Does It Cost to Hire a CRO Agency?

    Agencies that specialize in CRO vary in cost and pricing structures based on the agency and its experience and services. These agencies aren’t cheap, so expect to pay a decent amount.

    However, for the services they offer, the best CRO marketing agencies will make your investment worthwhile as these services pay for themselves.

    Here are the pricing models you can expect from conversion rate optimization agencies:

    • Performance-based: This pricing structure works based on results. So, you won’t pay an upfront retainer but rather based on the results they set out to achieve. This approach works because you won’t have to pay unless your agency has achieved what it promised. 
    • Project-based: Businesses will pay for a predetermined set of deliverables. For example, if you want to gain 10% more organic traffic, the agency will deliver that and only that. This model works if you want to optimize certain aspects of your CRO framework. 
    • Monthly Retainer: Businesses will pay a predetermined retainer every month. This model works if you need to create a CRO framework from the ground up, or your project is high-level and has loads of components to it.

    Summary: What Do CRO Agencies Cost?

    CRO agencies differ in cost based on the agency and its experience and services. These are the top price models:

    • Performance-based
    • Project-based
    • Monthly retainer

    What to Consider Before Hiring a CRO Agency

    So far, we’ve covered everything you need to know about CRO and the top agencies. But let’s look at what factors you need to consider before you hire a CRO agency for your business:

    • Cost: Marketing agencies are expensive. This is a crucial factor to consider. Regardless of your pricing model, expect to pay a generous amount for expert CRO services. However, the top CRO marketing agencies make these services worth every dime. The long-term revenue perks of CRO will cover your CRO agency costs. 
    • Impact of CRO: CRO shouldn’t be ignored. This approach enhances your entire business and how you engage and convert web visitors. Whether you’re a small business or a Fortune 500 Company, make CRO a top priority to accelerate business growth, reach, loyalty, reputation, credibility, and awareness. 
    • CRO Services: Some CRO agencies offer specialized services, while others have a broader range. If you know what you need, consider agencies with specific CRO services. But if you’re unsure about what you need or your project has many different elements, full-service agencies are a better choice. 
    • Your Current Marketing Performance: CRO isn’t going to fix all your problems. You need to evaluate your current marketing performance to understand what you need. If you have an impressive marketing performance and hit your KPIs, narrow down aspects of your brand and website to optimize for greater results. If your marketing performance is poor, you may need to consider additional methods outside CRO too.

    Summary: What to Consider Before Hiring a CRO Agency

    How Is Conversion Rate Optimization (CRO) Done?

    There are various conversion rate optimization strategies and best practices that marketers use for CRO. A few of these strategies include A/B testing, multivariate testing, and the LIFT model.

    A/B Testing

    A/B testing describes testing variables against each other to find out which one performs better.

    For example, to determine which landing page to use, marketers create one with a discount and another with free shipping. They test these two pages against each other to find out which consumers respond to better. 

    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 CRO strategies. Don’t believe A/B testing is essential? Over 77% of marketers use A/B testing on websites as they rely on this for CRO.

    Multivariate Testing

    Multivariate works similarly to A/B testing. However, unlike A/B testing where you test entire pages against each other, multivariate testing involves testing smaller sections of the page.

    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.

    Like A/B testing, this approach is pivotal to ensure even the smallest elements generate high conversion rates.

    The LIFT Model

    The LIFT model is a popular CRO framework. This framework reveals 6 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 testing and multivariate testing. Using the LIFT model, marketers can conduct a hypothesis and then test the hypotheses using A/B and multivariate testing.

    The 6 conversion factors expressed in the LIFT model are:

    • Value proposition: This provides the potential for CRO. How great is your value proposition to your target audience?
    • Relevance: Does your landing page relate to what the website visitor was hoping to find?
    • Clarity: Is your CTA and value proposition clearly defined on your landing pages?
    • Urgency: Do your visitors feel like they need to take action NOW?
    • Anxiety: What stresses do your web visitors have about taking your desired action?
    • Distractions: Are there any elements on your landing pages that lead visitors away from your desired action? 

    How Is Conversion Rate Optimization (CRO) Done?

    CRO can occur in three different ways. These methods include:

    • A/B Testing
    • Multivariate Testing
    • LIFT Model

    What to Look for and How to Evaluate a CRO Agency?

    Here are the top factors to evaluate for choosing a CRO agency:

    Custom CRO Frameworks

    We spoke about CRO frameworks and conversion rate optimization 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. 

    Ratings and Reviews

    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.

    Data-driven Strategies

    Successful CRO relies on in-depth data and 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!

    Customer Support

    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’re going to pay quite a price for CRO services, so you need premium support.

    Multi-channel Marketing

    CRO agencies aren’t digital marketing agencies. But 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.

    Experience and Team

    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 conversion rate optimization best practices. Check their portfolio to see what experience they have with brands like yours, and whether the agency has enough experience for what you need. 

    Summary:How to Evaluate and Choose a Conversion Rate Optimization (CRO) Agency?

    • Custom CRO Frameworks
    • Reviews and Ratings
    • Data-driven Strategies
    • Customer Support
    • Multi-channel Marketing
    • Experience and Team
