The worst part is that they’re click bait and tries to force you to click on them with their opaque close button. What do we even let them exist?
MaralDesa: why do you? I recommend using an adblocker such as Adblock or Ublock.
They exist because on most sites only the space is sold on where the add is displayed, and this place then is shared by companies displaying adds. These companies again get money from companies or basically everyone to display their add. Its so many adds some of these companies don’t even know which ones they are displaying in the end.
FBX: Sites that are less popular but that want to get more money will frequently accept advertising deals from shadier ad networks that offer higher rates. Those ad networks offer higher rates because the ads they serve are disreputable, and most sites don’t want to work with them so they have to raise their payout rates to get placements.
You’ll rarely get those kind of nasty ads on the very popular sites (NYT, google, reddit) but you’ll get them on more marginal sites with hosts that are trying to monetize more than their traffic allows.
