Google Search previously enforced a policy known as "First Click Free", whereby paywalled news websites were required to have a metered paywall for a minimum number of articles per-day (three, initially five) that could be accessed via results on Google Search or Google News. The site could still paywall other articles that were accessible via the page. This encouraged publications to allow their articles to be indexed by Google's web crawler, thus enhancing their prominence on Google Search and Google News.
