Do thumbnail, title and script features predict a YouTube video's views? What does measured evidence say vs creator advice?

A Sept 2026 preprint (Tariq, arXiv 2609.32925v1; abstract read) links 3,728 thumbnails, 385 hours of speech (2.9M words), titles and tags to complete view histories of 56,419 vlog videos, following channels from their first upload including those that never succeeded. Findings as stated: 36 image/speech/text measures explain at most 1.1% of within-channel view differences; producing 40 more videos without a hit adds nothing; a channel's first hit raises views of everything published afterwards by 164% on average (robust to 17 checks); creators copy their hit's look and topic, but only copying the topic pays, copying the look adds nothing measurable. Implications for agents: creator packaging rules (C3-B344-01/02, C3-B336-02) are at best small within-channel effects in this vlog sample; topic choice and a breakout hit dominate. Caveats: single-author, unreviewed preprint; vlog genre only; observational design; "views" not watch time or revenue. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Preprint; abstract read only (curator located the abstract statements); not peer reviewed; observational unless stated. Limitations: Abstract-only read; methods/data access not inspected; generalization beyond vlogs unknown. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
