"Their anguish was my nourishment."
Remember the golden rule of Smash: Don't jump into the ****. Ganondorf is a character with very limited approach options. If you just run in and start swinging, you're going to get punished.
My main advice is to just stop getting hit so much. You got hit by almost every projectile launched at you, and you got hit by a lot of ground moves that shouldn't have had a chance to connect. Try working on shielding, or better yet, powershielding, especially against projectiles. Dash + Powershield is Ganon's best option for dealing with projectiles.
Also, believe it or not, the more defensive you are, the more intimidating you are to your opponent. If you rush in and attack, you're playing into your opponent's strength (rather, you're giving your opponent the advantage by ignoring Ganon's weakness). If make them attack first, then they live in constant fear of getting stomped or flame choked - either one giving them 20+ damage. If your opponent is intimidated, they'll play more safely, which means you get to live longer.
A few more things - practice your Gerudo followups, practice edgeguarding with reverse Uair (especially off the edge - drop off Uair and drop off -> double jump -> uair are great ways to edgeguard). That's all I can think of right now... keep practicing
