This is another factor you need to be aware of when you do keyword research.

Keywords correspond to the cycle of buying.

The longer the keyword, the more advanced the searcher is in his buying decision and the more likely he is to buy (i. e. click on your affiliate link so that you get a commission.)

Which search is more likely to buy?

“Caribbean cruises” or “Caribbean cruises under $1000 Aruba”?

Use money keywords to sell products and get affiliate commissions.

If you find a long-tail money keyword, use it even if it says zero search volume.

They will convert much better and they will do so on much less traffic.

And this is another reason why you should use low-search long-tail keywords.

Use information keywords to get general visitors, then filter them with a lead magnet so that they sign up for your email list. Then build a relationship with them and get them ready, step by step, to buy a product.
