About Natália Eiras
Natália Eiras runs Perdida na Biblioteca, a Portuguese-language YouTube channel focused on book reviews, reading recaps and literary features from Brazil. She posts at a slow, personal pace, with long videos that often run several minutes, and her content covers novels, manga, manhwa and nonfiction. The channel's website and profile do not name a profession beyond the description's mention of journalism.
Her channel has about 3,400 subscribers and a median of 58 views per video, so the audience is small and likely made up of dedicated Brazilian readers who follow slow booktube. Audience age and gender figures are estimates and should be treated as directional only. No uploads appeared in the last 90 days, which lowers the reliability of recent reach.
For a sponsored integration, estimates put one video at $150 to $250. At that rate the effective CPM is about $20 to $35 per 1,000 views, which is higher than the $10 typical for paid ads, so the channel suits small book publishers testing a niche Brazilian audience.
