Is using a comma or vertical bar better for keyword breaks in alt text?

If two or three keywords are added to the Alt Text of an image, is Comma (,) or Vertical Bar (|) good as break??

Hi @Hokage_San,

I haven't seen anyone add 2 or 3 keywords for Alt. But in my own opinion, you should use Comma(,).
Hope it gives you another choice.
