CRO marketing involves outlining a process oriented methodology that helps in the growth of visitor percentage to the website whilst driving them to take the desired action. These can be a lot of different types of activities that include subscribing to a mailing list, filling out a specific form, or registering for a seminar. The key reason why businesses should invest in CRO marketing is that it converts leads. It costs a lot of time and resources to get traffic to a website. This could be either via social media, paid campaigns, or SEO efforts. These are significant investments, but they are a total waste of resources if after users get to the website, they are not converting into leads or customers. This is where CRO marketing plays a vital role.
