So here's the deal: I completely removed Adsense from my site a while ago and replaced them all with affiliate ads served through google's doubleclick. Prior to that I just had text links for my affiliate sales, but now i've got text links plus an extra 400,000 impressions from the image ads. My text links always did okay, so I was obviously expecting my earnings to go up quite a lot, but it's actually been a lot less than i was hoping.
I've been doing some reading and i've come across the big hoo-haa caused by Apple's ITP. apparently their new policy is messing with advertiser's affiliate cookies. they only last for a maximum of 24 hours now, regardless of what the advertiser sets them as, and I think i'm right in saying that if you send an affiliate link through doubleclick first then it's even worse - they won't set the cookie at all.
have i got that right?
So i'm wondering if anyone has managed to get their head around it all yet.
would the results improve if i hard-coded the affiliate ad links directly onto my page, without sending them through a third-party like doubleclick first?
i don't sell ad space on my site, so removing doubleclick would be a pain, but not the end of the world.
the more i read up on it, the more i'm thinking that sending affiliate links through doubleclick is a bad idea.
edit: i've just found some information from a big affiliate program which confirms doubleclick might have problems: tradedoubler.com/en/global-blog/itp-2-readiness/
