No offence OP..but i dont believe you!
Here are sharks that know everything about KW research, long tail, YT making and ranking and so on...and no-one seems to be able to get a long tail KW that has 8k searches/month that would make 50$/day that easily....especially with no backlinks! common!
A 8k KW is already a competitive keyword...no damn way u were able to rank it and no way it did not have any competition!
Your story just doesn't add up dude! Sorry to s#it on your parade! maybe CB-YT newbies would belive you...but since i've been into YT and CB marketing for already 2 years....what u say...does nto make any sense!
The idea in general is fine:''find low competition long tail keyword with lots of searches and rank without efforts" - this is the dream of any seasoned and newbie IM-er..
LOL dude! I dont really post negative comments ....but ur thread deserved it!
