how does it look now?

Well, it's not ugly :joy:

It's saying "too many redirects".

Issue with iframes is, that it is always shitty on mobile. How about a link only?

The phrase "Embedded Popularity Application" strikes me as odd.

I would suggest not focusing on the method of obtaining the data, but on the data itself. e.g. "Popular Prebid.js Modules" as a title and maybe as a description "These are the most commonly deployed Prebid.js modules as seen by Prebid's integration monitor tool on live websites."

Though I though the tool wasn't called PIM anymore?

@patmmccann - is adding this to the download page still relevant?

closing now that we have this elsewhere
