I actually started doing this with a Clickbank online TV streaming offer.
Superbowl Sunday is always the best day for it. I don't run this anymore cause I basically focus on Facebook and Display Ads now...but it is still definitely worth a shot....in fact I see others still doing it every single Sunday, Monday Night Football, and Thursday night even March Madness, NASCAR, Soccer Cricket whatever....
Profit margins are bit slimmer since it is a 10 year method....but there are new offers available now that allow people to get better TV programs.
The Main Offer: Bring Me Sports Toolbar
The Angle: 24/7 Sports (Streaming)
The Bring Me Sports Toolbar offer pays out around $3.25 per install and converts when the user installs the toolbar onto their desktop browser.
It is just one offer that works...there's a ton of others. The downside is it only accepts desktop.... so you need a way to redirect mobile traffic if you cant filter it out.
Traffic Source: Bing Search worked best (target keywords like watch football, watch NFL, superbowl, live streaming, etc...)
Watch Live NFL
Live NFL Coverage Online. Click Here to Install!
The main thing to remember here is the targeting must be desktop and US, but Bing will force you to deliver some traffic to mobile...thats where the mobile redirect to the 24/7 streaming offer is so important to capture the mobile traffic. Bring Me Sports only converts on Desktop but it converts well.
It is highly recommended you use a landing page! Here is one I paid a designer to build for about $400.
Keep in mind this method not only works for NFL....there are several sporting events including the Daytona 500...Also NHL, NBA, March Madness all generated profits for me in the past...
As for terms the only place you may get some problems is with Bing themselves...sometimes they deny ads if they contain brands... So instead of saying Watch NFL you have to say "Watch Football".
If you want to see this method in action then it is really simple to spy and see it is still working....You just need to change your IP to a US ip (I use Hide My Ass) since I am in Canada....Then go to Bing search and start searching for "watch football": related keywords...guaranteed you will see a few affiliates on there still banking on this method.
This method also works on Facebook ads.
