The '-azo' Ending
'Vistazo' comes from 'vista' (view/sight). The ending '-azo' in Spanish often suggests a quick, sharp action or a hit. So, a 'vistazo' is like a 'quick hit' with your eyes.
It's a Noun, Not a Verb
Mistake: “Don't say: 'Yo vistazo el libro.' (I glance the book.)”
Correction: Say: 'Yo le echo un vistazo al libro.' (Literally: I throw a glance at the book.) 'Vistazo' is a thing (a noun), not an action (a verb). You need a verb like 'echar' (to throw) or 'dar' (to give) to perform the action.
