How much do you modify the content of an article for you to update the publish date?

Hi y'all, just wondering what you guys think here.

In general, I don't update an article's publish date without changing the content of the page. However, I'm still not sure how much qualifies as an update. I'm used to updating the date when I do a substantial edit or rewrite (adding or rewriting at least one section of the article).

Now and then, though, I'll be scrolling through my content and make a few small changes to wording, paragraph breaks, headers, that sorta thing. Do you think this type of edit is worth updating the publish date for?
