This chart breaks down the searches on this keyword by the device used to search it.  The purpose of this is to highlight any outliers.

Don't expect a specific split. There are some keywords that get searched from mobile devices more often than others. And, some searches are more likely to be done from a desktop. A strong swing in either direction might influence the kind of content you create or the format you use. 

If this keyword's mobile searches stray far from usual patterns, you will see low bars on the "Low Mobile Indicator" or even "High Mobile" ratings.
