How much is your attention worth to advertisers?
See all prebid bids being placed in your browser. Click the gavel icon and a popup window will show. Then just go about your browsing session. If the site you're on is using prebid, this window will display the creative sizes ad exchanges are bidding on, and the prices they're offering to pay for your impression in real time.
The extension shows:
* url
* which exchanges submitted bids
* the creative sizes being submitted
* the CPM price of the bids
You can export the results of your session with the Download Data button, which will give all the results shown in the extension window plus the unix timestamp of each impression in JSON format.
This will work on several sites. A few examples to try out are: wsj.com, washingtonpost.com, cnn.com, buzzfeed.com, buzzfeednews.com, espn.com, recode.net, and vox.com.
