Credits to my mom, who found out about this while trying to buy something from Amazon.com. There is a Google Adwords advertiser who somehow managed to bypass Google's trademark filter and bid on the keyword "amazon" for his ad. So when you search for "amazon" you should see one ad at the top of the search results. When you click on it from your desktop, it just redirects you to Amazon.com. However, if you click on it with phone, you get redirected to "amazon.com.freebie.services/somecpapage" with an elegant CPA landing page with a fake promotional anniversary giveaway. I believe the site checks the user agent and redirects accordingly. I also believe Google was redirected to amazon.com and never saw the CPA page. I'm guessing the "freebie.services" owner appended the amazon.com add-on domain to trick Google into thinking it's actually Amazon.com, and/or to trick the users. This guy did the same thing with "bestbuy" (bestbuy.com.freebie.services). The way I see it, the CPA company would still pay the dude, because the traffic is legitimate, and the only thing at risk is the Adwords account, which you can always get again. Thoughts?
