You neglected to state what their "ideology" is.
It's a fairly left wing paper, but not crazy-left. Very middle class. "Guardian reader" is pretty much a social class. They even had a dating service for a long time!
I'm not criticising; I think they're a little too indignant at times - woke even - but overall they're probably the least objectionable newspaper in the UK, maybe the world.
Kind of like the left wing mirror of The Times.
