To get organic traffic your vids need engagement – you have to have comments on. Another way to do it would be to clip your biggest wins/ max wins and create shorts and use them not just on YouTube but also TikTok etc with links to your YouTube channel.
Easiest way to get there fast would be to do something you would hate – challenge one of the other uk slot players like the challenges you used to do v phil . There are a few who seem to play with their own money and are miserable bastards and degenerates so would be up for it. If a few of their followers see you moaning on their channels they might sub to you as well – would be a very easy way to get the few extra thousand you need. Stop n step/ Craigslots/ rocknrolla would benefit from a tie up with you as a one off and you would benefit from them
