How to build from intermediate to advanced

I’m currently stuck around an intermediate playing level. My ability to learn riffs is fairly good depending on the difficulty of them and the same goes for solos. My speed is lacking but to be honest I haven’t worked on one fast solo enough to even build decent speed so that’s on me. I don’t wanna be stuck in this zone of kinda struggling through solos and riffs if I’m not building toward something better. I feel like my technique could be improved but I’m not really sure how. What practice methods, YouTubers, etc did yall use in order to consistently get good at learning songs and playing them to a level where you would sound good to even other guitar players. Also how long should I practice each day, I currently just kinda mess around with a few songs around 30 minutes to an hour each day but there’s no real structure to it.
