The adverb in French usually follows the conjugated verb.
In compound tenses (where there are two verbs, like the futur proche and the passé composé), adverbs are placed between the two verbs (the auxiliary and the main verb):
Je vais bientôt partir.
Tu as trop parlé.
TIP: Some longer adverbs ending in -ment may follow the past participle.
Negation: If the conjugated verb is in the negative, the adverb follows the negation.
Je ne vais pas bientôt partir.
Tu n’as pas trop parlé.
