Almost every Wordle answer has exactly two vowels. A few have one or three, but two is the safe assumption, and it changes how you play. You don't need two guesses to hunt vowels; you need to find them once and move on.
Vowels give a word its frame. Consonants separate the words that share that frame. Once you know the answer is _OUND, the first letter decides everything: BOUND, FOUND, HOUND, MOUND, POUND, ROUND, SOUND, WOUND. The vowels are settled; only a consonant breaks the tie.
When to chase more vowels
If your opener finds no vowel at all, reset with a word that tests three new ones, such as OUTER or NOISE. Finding the vowels is worth a full guess when you have none, and rarely worth a second.
Don't forget Y
Treat Y as a vowel when no A, E, I, O, or U will fit. Answers like GLYPH, NYMPH, and CRYPT catch players who only ever test the usual five.
A sequence that works
Open with two vowels and three common consonants. Read which vowels landed and where. Then play a word that locks those vowel positions and adds new consonants. By the third guess you should be placing letters, not searching for them.
