I've been doing this exact method lately, yet for some reason I'm not getting hardly any clicks or conversions, despite the fact that I have a well designed site (gamehacksholiday . info), well placed comments with timed replies over 10+ youtube accounts, and certainly on good video choices with the exact type of traffic that converts... yet... nothing. I've commented nearly 10 target videos perfectly tailored to this method (using Battlefield 4), and still I only get a few impressions, hardly any clicks, and almost no income. What the hell is going on? Thankfully I make $100+ a day with Adsense and CPA, but still I'd like to know what the deal is.. Seems like people just aren't taking to these type of comments anymore. They've wised up it seems.. What else could it be?
