Audits a LinkedIn newsletter (author profile or specific issue) for the signals that drive subscriber growth: cadence consistency, 900–1500 word sweet spot, hook density, cover-image quality, CTA placement, and syndication setup.
Paste a newsletter homepage URL (linkedin.com/newsletters/<id>) or a single issue (linkedin.com/pulse/<slug>). LinkedIn rate-limits scraping — we only pull the public preview; sign-in-gated content is not visible to us.
