This invention increases the conversion rate of website surfers to paid customers. Extracted texts of the content are tokenized and then scored with normalized value [0, 1] to measure their significance. Intra-token, inter-token, extra-token, and tagged token features are used to characterize each individual token. Scores of sentences, paragraphs, sections, and even chapters can be calculated with various methods based on the scores of tokens. Then, the content is redacted according to the calculated scores. Customers can view the redacted content for free. If interested, they can purchase the content and view the full, non-redacted version of the content. The present invention is useful in publication and monetization of digital contents such as e-books.
