The use of the present tense should be avoided in most cases.

Present tense may be acceptable when referring to non-specific situations that are permanent or virtually guaranteed not to change for several days or longer: The Cleveland Guardians are in the midst of an unforgettable season; Scott Boras isn’t one to roll over in contract negotiations.

The use of the past tense should be favored whenever possible. Your content will almost always be consumed after you’ve created it — in most cases, several days after — so you should write with a future audience in mind.
