Find out how much ad networks are bidding in real time

Ever wanted to find the winning bid for a specific ad unit? How on earth would you go about determining that? How about discovering which ad networks were bidding on an ad unit and what their bids were?

Your first thought might be: “I’m going to need some serious technical skills and a lot of time to figure this one out.” Think again! In this post, I’d like to show you how you can do all that and much more in mere seconds with PubGuru Ad Inspector!

Don’t know what PubGuru Ad Inspector is? It’s a free Chrome extension developed by MonetizeMore crammed full of features to make the life of any publisher super simple! It allows publishers to analyze ad setups for any website and gain insight into ad units, bidders, GDPR, technical logs, and much more.

For now, let me show you how to get a handle on your bidders without breaking a sweat.

How to discover the winning bid for any ad unit

Start by downloading the PubGuru Ad Inspector Chrome extension here and enable it on the website you want to analyze the ad units. Your screen will look something like this:


For this example, we are going to focus on the 300×600 sidebar ad unit numbered #2. You can view the winning bidder details by either hovering your mouse over the ad unit or clicking on the “inspect” link in the ad unit.

As you can see, the bidder ix or Index Exchange won the bid at a $0.61 CPM and served a 300×250 ad within the ad unit. This ad unit was also running a header bidding auction.

Take a look at the sections highlighted in the screenshot below:


As mentioned, when clicking on the “inspect” link within the ad unit, additional information gets displayed in the PubGuru Ad Inspector dashboard under the Bidder section. That takes me to the next feature I want to show you.

How to view real-time bids and non-winning bids

Let’s zoom in on the Bidder section on the dashboard for a second. As you can see, PubGuru Ad Inspector allows you to see which ad networks bid on a specific ad unit and what their bids were.

We can see that for the 300×250 ad size there where only two bidders:

Ix with a bid of $0.6 and Aol with a bid of $0.12. Adding more ad networks to bid on this ad unit would increase bidding competition and undoubtedly lead to higher ad revenue.


As you can see from the screenshot above, simultaneously, there was also an auction for the 300×600 ad size. Four separate bidders or ad networks took part in that auction whereby Index Exchange also won with a bid of $0.6. However, since the winning bid for the 300×250 ad size was $0.61, that ad served.


With PubGuru Ad Inspector, you’ll never again wonder which bidder won an auction or why one ad size served above another. You can analyze any ad unit this way – no limits!
