I haven't heard anything. But they don't seem to be very interested in making them responsive (like they're pushing the ads to be) plus they flat out told me last year they weren't going to be putting resources into fixing a bug I found with them, so... it wouldn't surprise me.
There was a time they made me a lot of money. But that was years ago.
They are still showing.I do not see them only if I use my Mobile phone.I hope that they will keep Adlinks.If I tell you that Adlinks made each month about 50% of my earnings then you will probably not believe me but it is true.And I talk here about couple thousand Euro's only from Adlinks.They perform much much better than any other units.
I have ad links on a few pages still and they do about 25% of the revenue on those pages. What I don't know is if the overall page revenue would decrease if I took them off or if the overall page revenue would increase if I added them to more pages. More ads often does not translate into more revenue.
I place always full combination if it is possible 3Adlinks unit + 3 Adunit. Because my websites are about giving informations it is possible that it is exacly reason that Adlinks unit perform excellent.
As i can remember Adlink units are 2x click that count as 1. First click then go to another page then you need to click again and that click count.
One Adlinks unit is below horizontal menu bar, one is above part of website where informations are given to visitor and one is vertical aside.
