Trying to Up my Marketing Game

Hello everyone, I hope ya’ll are doing fine.

I’m a complete newbie when it comes to marketing, especially digital marketing. I just landed my first job with an agency and am looking for any tips, educational resources, and fundamentals I need to learn to get a foothold in. I have a little bit of experience with social media (I had one viral post of a meme lol) so there’s that.
SEMrush

Tips or suggestions of any kind is greatly appreciated, help an idiot out, thanks!
