It is a good thing that websites are given the option to refuse cookies. They can claim enabling cookies will provide you with a better experience, but no one wants to feel they are being observed.

I’m almost positive most of the users reject cookies when the alarming pop-ups show up. What’s evident is, as advertisers, we need to find better ways to identify users.

There is a JavaScript technique called “browser fingerprinting,” which, based on browser’s information, will assign a random number to a visitor, and try to figure it out if it’s her again once she comes back to a page.

There are libraries like ClientJS, specifically built for this purpose.

Is not 100% accurate, but it is a reliable way to make an educated guess about returning visitors.

You should take this as a sophiscated way to have a second change to escalate permission.

If you didn’t convince a person to become a subscriber or a customer (and create an account in your system) the first time she visits your page, you can try with a different, more relevant, message by identifying is the same person visiting again.
