"Great for Privacy And Security"
4.5/5
What do you like best about 33Across?

33Across is the solution for those who want to deal with cookies and data that they produce but don't want to give away. It's a great solution for privacy and security. A game-changing tool at its very best. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

Being a relevantly newer concept and solution its needs better optimization to be done. But I guess with further installments and upgrades, in the newer versions we might see a better all in all package. Review collected by and hosted on G2.com.

"Attempting to move past cookies to create addressability for marketers and publishers"
3/5
What do you like best about 33Across?

I like their intent - the desire to create a system that allows marketers to reach target audiences even with the demise of cookies. They claim they have reach across multiple DSPs and help publishers earn higher CPMs. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

I'm not sure how well it actually works. When we run campaigns on their platforms, I don't notice any real uptick in performance, reach, delivery, etc. It seems like more promise than actual delivered results. Review collected by and hosted on G2.com.

I value how 33across allows for people to be in complete control over their work. Often time people have to lose a part(s) of their work but here it does not happen. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

I do wish that in beginning it is easier to navigate and gain control over. Upon starting I was a bit confused but nothing that can't easily be fixed with some slight adjustments. Review collected by and hosted on G2.com.

"33Across Monetization Review"
4/5
What do you like best about 33Across?

It aids in the monetization of our webapp. 33Across is a free open web for consumers, and content creators such as myself will be able to monetize their work. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

It occasionally gathers private information from consumers, which puts that information at risk; aside from that, everything seems to be in order to me. Review collected by and hosted on G2.com.

"Good software"
2.5/5
What do you like best about 33Across?

valuable information to help hone your business and understand user behavior. Supports understanding of where consumers are focusing on your site and what content they are engaging. Tracking user's behavior. Hard to have any privacy these days. Review collected by and hosted on G2.com.

What do you dislike about 33Across?

There is no postsale support. Postsale support needs to be better; perhaps they need to set up a team. Some information I feel is like spam. This needs to be improved. Review collected by and hosted on G2.com.
