I don't know the secret to having poems trend
There are some poems I feel certain that they will trend and they do not
I have read many excellent poems that did not trend, the list seems unending
I still feel that they are worthwhile ,especially when they caused a laugh or a smile or even a  tear when I really need a good cry
If the poems effect me or others I feel they are successful no matter whether they are trending or not
I feel bad for fellow poets if they get discouraged if their poems don't trend, the heart is such a fragile thing to mend, especially if discouragement sets in causing them to question their talents or ability.
My advice would be just write, if it trends great; if not keep writing don't give up
If you are writing to an Audience of one or 500 just get your feelings out you many be surprised by the results someday, you poems may really touch peoples lives that can relate to them.
Whether the poems trend or not Keep Writing!
