Definition
The Google Payday Loan update, first deployed on June 11, 2013 (with a version 2.0 in June 2014), specifically targeted heavily spammed queries in sectors like payday loans, gambling, pharmaceuticals, and adult content. Unlike Penguin, which targeted link spam in general, Payday Loan tackled the particularly aggressive spam techniques used in these specific niches: site hacking, link injection, deceptive redirects, and massive creation of spam pages. This update demonstrated Google's ability to apply sector-specific filters.
