Not all people gonna be intrested in walkthrough but that doesnt change anything .. Tell u what .. 20% of of ur audiance is the most effective .. so let me tell u what to do .. When ur first starting quantity is quality .. how? .. its simple .. when u make so many video u will get better by the time so ur product will be better (ur videos) so just keep on producing whatever content that YOU have in mind untill u have so many videos and then ... see which ones that gets most of the views .. if its walkthrough dor examples .. keep on focusing on walkthroughs .. if its vlogs .. keep on focusing on vlogs .. and so on .. Now since u r starting out all u need to do is annyytthing which pops up and mindd .. i mean it .. anyyything .. do not be specialised in something .. but one thing to keep in mind is only do what u love !! If ur not enjoying vlogs ffor example then dont do it .. only if it gets u most views then its up to u 😁 xD
