Here's the scenario: you need to capture a search phrase that is very widely used in common search, but the term is considered antiquated, overly vernacular, insensitive or outright offensive within the client's industry.
In this case, searchers overwhelmingly look for "nursing homes," but the term has too many negative connotations to the client's customers, so they won't use it on-page.
Some obvious thoughts are to build IBLs or write an op-ed/blog series about why the term is offensive. Any other ideas?
