Paid landing pages
Paid landing pages generally use noindex. However, if a copy of the homepage is used for paid testing (on a separate url), and a winning variation may then be pushed live to replace the current homepage: should this be treated almost like a test, and a rel-canonical is warranted (to the canonical HP) rather than a noindex? Also to prevent human error when the test version is pushed with noindex still there :)
