"Easy to use but lacing features"
3/5
What do you like best about OpenX?

As a product to help monetize our backfill on the display side, it generated decent fill rates and CPMs. Review collected by and hosted on G2.com.

What do you dislike about OpenX?

As a network, it could have been an easier process to implement a large group of sites or make bulk edits to floor rates and passback tags. Review collected by and hosted on G2.com.

"OpenX ad exchange"
3/5
What do you like best about OpenX?

OpenX made it very easy to opt in or out to RTB. Setting up campaigns is also quite easy to do. They have a massive help center, although written in technical language so may be a little bit hard to understand to someone new. Account management is fantastic, they are very helpful and easy to reach when needed. Review collected by and hosted on G2.com.

What do you dislike about OpenX?

The system tends to get slow sometimes, Also sometimes changes to live order do not save, if order is not paused for the time to make changes. OpenX does not provide ad review center on RTB and dealing with ad issue can get a long process. I would like to see more flexibility with dates when creating scheduled reports Review collected by and hosted on G2.com.

"Useful Ad Network monetization solutions"
4/5
What do you like best about OpenX?

Team was great and very involved on helping to setup the account and make sure we started to see delivery quickly. They offered competitive value on the Web units. Review collected by and hosted on G2.com.

What do you dislike about OpenX?

They did not always provide high volume fill so although they offered to help diversify our setup they were not really one of the big contributors as I had hoped. Over time I believe we can get more from them. Review collected by and hosted on G2.com.

"OpenX / Revive Ad Server, free, but at what cost?"
0/5
What do you like best about OpenX?

The free price tag is always a very inviting factor when choosing an ad network, however, free comes with a cost in this case. Expect zero support and zero reliability should something go wrong. Review collected by and hosted on G2.com.

What do you dislike about OpenX?

We have used OpenX for about 3 years. It's constantly being hacked. Security holes and vulnerabilities run rampant and it always takes a loss of data or corruption of files to be reported before OpenX will do anything about it. There is also very limited support. The community forum is a graveyard of unanswered questions. Review collected by and hosted on G2.com.

"OpenX Review"
3/5
What do you like best about OpenX?

Ease of setup. It's quite a set and forget platform although this might be bad if you want special customizations and specific price floors. Review collected by and hosted on G2.com.

What do you dislike about OpenX?

Doesn't play well with passing to google tags. Lack of data about bids/prices/floors. Review collected by and hosted on G2.com.

"OpenX - Cheap Inventory. You get what you pay for."
1/5
What do you like best about OpenX?

Broad reach for display units. Cheapest CPM prices out there for IAB standard units. Review collected by and hosted on G2.com.

What do you dislike about OpenX?

Extremely low quality (shady) inventory: We were continuously uncertain where our ads were running or whether they were visible at all. We saw incredibly low click through rates/survey completion rates from this inventory. Customer service liaisons were primarily concerned with pushing additional spend as opposed to rectifying issues, Review collected by and hosted on G2.com.
