Why do I see blank spaces when reporting on articles?

Question

I created a report or dashboard to measure article statistics, but the article title is occasionally blank. Why am I seeing this?

Answer

Blank article titles occur if the article was deleted, archived, or unpublished.

Explore will continue reporting on how many views or ratings the deleted article received, but the title and other article information will not be displayed.

For information on removing these blank attributes from the report, see this article: Hiding rows and columns.
