I'm not sure this is the right forum to post this, anyway tonight I came across a weird Facebook ad. The ad was a simple "Fly to New York City from 350 € this summer. Click and see". As many of you would know, Skyscanner pays for lead out. So usually a publisher links to Skyscanner's search results with a deeplink, and IF the user clicks on any of the flights and goes to the actual booking site, Skyscanners pays a commission for the lead out. This ad led to a "loading" page saying "we're finding the best offer", then passed directly to a Skyscanner's leadout, bypassing the Skyscanner search results page (I could clearly see the Tradedoubler link for a moment). Is this legit? As far I know, no. And, more important, how could they do that? Some sort of scraper? Experts' advice needed!
