One drawback of 33Across is that novice users may find the site somewhat complicated. More user-friendly documentation or guided onboarding could improve the experience, as some functions and reporting tools have a learning curve. Review collected by and hosted on G2.com.

"Old instructions for WordPress installation"
4.5/5
What do you like best about 33Across?

The promise of cookieless revenue and feature like SiteCTRL for tracking user engagement attracted me to register on 33Across. Weekly email reports are fine, too. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

Here's the main issue I'm facing right now. I'm developing a new site, on WordPress 6.0.1 and their instructions for JavaScript snippet installation are outdated. It's still possible to make it work, but it'll take me a lot more time than I thought. Review collected by and hosted on G2.com.

"A noble cause, changing Internet for better, respecting our privacy!"
4.5/5
What do you like best about 33Across?

I absolutely love the concept and the idea on which 33Across has been formed. Respecting each individual's privacy where cookies are not saved, your data is not accessible for the giants on the internet to be saved and sold to make profits. It's a new, much more evolved way of using the internet which makes open web work without cookies in a way that is simple and fair for publishers. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

It can be a little tricky at first to understand and get used to since most people do not understand this new way to access the internet, how it works with not saving cookies and how can we go ahead and make most of this new way of taking internet forward. I believe the marketing of the product should also be focused upon since in today's day and age privacy is such a big concern for most people and how our data is being shared by giant conglomerates and sold in huge numbers, I firmly believe this is the way forward and a lot more is needed to be done to expand it.
