500 Elo after one month: how can I improve?

there's alot of free chess content on youtube... find a channel you like and listen to them talk chess would be my suggestion.
For beginners the main focus is always on not blundering. Take a look at the puzzles on this site for tactics practice, they're very good.

There are Youtube channels of some really good player-teachers that are skilled at teaching others chess. Sorry, if I skewer the names, but a few that I like are Anna Cromwell, Gothamchess, and Hikaru Nacaguru(?), and Igor Smirnov.
Also the puzzles and other learning tools here are great.
I also just discovered a site call DecodeChess, in which you can analyze your games and it explains why certain moves are best.
I’d love to get to 800 Elo this year. Can someone help me improve?
