Thanks for the comment. There have been a lot of studies done using the general TF-IDF approach. You can read about it on https://en.wikipedia.org/wiki/Tf%E2%80%93idf

This is more or less part of the definition of clickbait: an article with a title that misrepresents the content of the article in order to garner more views.

It seems like it'd at least catch some. How else would you measure?
