Frequency Adverbs and their relationship with Present Simple

The adverbs of frequency are what we use to express the periodicity with which an action is performed. That is, when we want to talk about the frequency with which we do something or in which something happens. These are the most used adverbs of frequency and their percentage of frequency:

The Position of the Adverb in a Sentence: 

An adverb of frequency goes before a main verb:

Subject + adverb + main verb

An adverb of frequency goes after the verb To Be:

Subject + to be + adverb

When we use an auxiliary verb (have, will, must, might, could, would, can, etc.), the adverb is placed between the auxiliary and the main verb:

Subject + auxiliary + adverb + main verb

In negative sentences we place the frequency adverb between the auxiliary don't or doesn't and the main verb:

Subject + don't / doesn't + frequency adverb + main verb

In interrogative sentences, the frequency adverb will be placed between the subject and the main verb:

Do / does + subject + frequency adverb + main verb + (complement)?

Relationship they have with Present Simple

Adverbs of frequency are often used to indicate routine or repeated activities, so they are often used with the present simple tense. If a sentence has only one verb, place the adverb of frequency in the middle of the sentence so that it is positioned after the subject but before the verb.
