This is breaking YouTube rules?
Ahahaha, no way it's fine!
Although people wouldn't like it when it comes to putting like half naked women on a thumbnail with a misleading title when the video isn't about women . They'll bring you a lot of dislikes but a lot of views at the same time.
Yes it's true, additional text and such will attract viewers to your videos. Take a look at my video's thumbnails, I've Photoshopped most of them to make it look like something they want to click on and view them
Haha
Great. I will in fact take advantage of these thumbnails then.
Its amazing BTW, how creative your thumbnails are.
great. thanks.I say it's better than having just the video as a thumbnail.
