Top conversion rate optimization tools to include in your CRO Stack

Authors

Depending on the conversion rate optimization services and the hypothesis that you'll want to test, each step of the optimization process requires specific tools to either gather, manipulate or crunch the data.

There is a lot of conversion rate optimization tools out there from free, low cost to high priced enterprise level ones so depending on your yearly revenue and profits + size of the business, you want to get the best possible.

Remember that if you have bad data and you make a strategy based on it, you may do more harm then good. Don't trust data until you really double of triple check it.

Content & competition research

The more insights and data you have on the message (what resonates with your audience) and what the competition does (be careful here as you don't know why they do what they do).

What are the best CRO tools?

It depends on the conversion rate optimization agency as one has its own stack of tools that they feel comfortable with and are reliable. The best conversion rate optimization tools are the ones we use most and have mastered them.

In case you're hiring an agency for your eCommerce, saas or lead gen business, you need to ask them what tools they use and then subscribe to them. You want to have full ownership of your data and stats and just share it with the CRO agency or a consultant.

You can get away with some free conversion optimization tools, but they may be limited in what you can do with them or have some drawbacks like speed. But A/B testing has become quite affordable as it used to be so test everything.
