Betfred, Bet365, William Hill, Genesis. With all those brands, my banners every now and then stopped working. They are actually present and visible on the website, but after clicking they take you to a 404 or to other no-money making destination. My banners are not iframes, nor scripts taken from the affiliate interface, but jpg with a text link. So the argument can not be that this or that promo is over. Funny thing is that the text link is working but in a combination with the jpg it is not working. This is indeed not a rule... First I was thinking the issue was me putting it wrongly on the pages, but after digging deeper into it I see there must be something I technically don't get. Can the bookie simply set "make this text link non working with jpg from tomorrow"? In any case, please share your experience with this and pls let me know if I am missing anything basic here.
ps. I am not blaming the brands for doing anything like stealing the traffic. This might be some kind of protection they might be having not to upset the UKGC
