UC browser (proxy browsers) in non-US countries being targeted for US only ads
I want to run my campaign for US only traffic.
When I run my ad, the incoming traffic to my site from Bing also contains traffic coming from proxy browsers like UC browsers (proxy browsers) etc. which are are originally from India, Pakistan etc. In my reports, I can see that those users are not from US but because the proxy service in their browser runs in US, they get targeted for my ad.
It seems Bing (and its associates) does not check HTTP_X_FORWARDED_FOR header sent by proxy browsers.
Normally when a user interacts with Bing, this would be the flow:
(User) [REMOTE_ADDR] <-> (Bing)
But when using Opera Mini, UC etc.
(User) [REMOTE_ADDR] <-> (Opera/UC proxy in US) [User's REMOTE_ADDR as HTTP_X_FORWARDED_FOR, REMOTE_ADDR of proxy] <-> (Bing)
UC Browser's headers reveal:
REMOTE_ADDR: Their US based proxy's IP
X_FORWARDED_FOR: User's real IP
My Bing Ads account is X0004TM6
I raised this issue about the traffic from UC Browser and other proxies being mistaken as US traffic in Bing ads suggestions forum in 2015. I stopped using Bing ads for the same reason because I was getting junk traffic from UC Browser (from India), at a very high CPC, which cannot even be monetized. Recently I started using Bing ads again. The problem is amplified right now.
I have chosen only: "People in your targeted locations" in my campaign settings.
I have logs to back my claims up.
Kindly fix this issue as I am losing money for wrongly targeted traffic. I am sure it is affecting anyone who is targeting for US only.
