FAQs about CRO companies

Now that you have seen some options, you might still have questions about CRO companies and their services. Below are a few common questions about CRO companies and services to help guide you through the process.

Do I need CRO services?

Before embarking on a CRO journey, you may pause and wonder if you require the service. CRO is not a one-size-fits-all solution, but it will help a majority of companies improve their bottom line and online presence.

CRO can help with the following goals and benefits:

• Increasing your customer lifetime value (CLV) by improving sales and re-engagement efforts
• Generating more revenue consistently over time
• Encouraging site visitors to act instead of browsing
• Making choices based on data from converted leads

If you want to accomplish one or more of the goals above, CRO will help. Performing CRO ensures that you are approaching your audience from the best angle. Above all, you can expect more leads and revenue from the right CRO methods.

What services does a CRO company offer?

CRO services can vary depending on your agency, goals, budget, and needs. Basic CRO services might include the following:

• Creating buyer personas
• Building out website copy
• Heatmap analysis
• A/B testing
• User testing
• Creating upsell plans
• Diversifying and personalizing calls to action (CTAs)
• Adding social proof to your site

Some companies may perform CRO services internally. However, there are many mistakes and nuances that aren’t obvious to untrained experts. That’s why CRO agencies exist — to make it easier for companies in any industry to get results while saving time.

How do I choose between the best CRO agencies?

When picking your ideal CRO agency, you must first consider your goals. What do you want to get out of your services? How can your CRO agency be supportive in your business journey?

For example, if you want to increase mobile conversions specifically, you need a company that is well-versed in mobile marketing. You also want personalized solutions — every company is different, and their CRO tactics should be, too!

Other factors include:

• Your company size
• Budget
• Location
• In-house features

A digital marketing agency like WebFX is an all-encompassing solution for any need. We have experience in web design, SEO, and paid advertising, all of which help your conversion rate.

What do CRO services cost?

Each company will have their own pricing plans, but you can expect to spend about $1500 on CRO services. The more optimization you want, the more you can expect to pay.

CRO services are an ongoing investment that will improve your company over time. As you continue optimizing your site, you can expect to see a higher return on investment (ROI) and a stronger bottom line.
