Compare multiple headline searches as counts or as shares of all articles recorded.
Try: ukraine, gaza, sudan; covid against flu, as a share; trump on bbc.com against nytimes.com; el niño, drought, floods.
A headline counts as one “story” on its first appearance in any source in one week. A headline counts for one “outlet” the first time it appears at a given source in one week. A headline counts for one “article” every time it appears whatsoever, regardless of previous appearances globally or for a given source. A share is of the same measure over every headline collected that month in the data the term includes, or over its sources'. GDELT's set of sources is not constant (between 40 and 53 million articles a year since 2020, from a changing mix of sites), so a share across years is against a moving base; a term's share of one source's headlines is against that source's own output.
