SEO is applicable to any search engine. Google is only used as an example because it is relevant/responsible to 90% of their traffic - but nothing said here is technically specific to Google. Websites are constructed using standardized protocols and languages - changes made to make Google happy will also make DuckDuckGo happy, at least with regards to "readability". How "visible" you are in a search is based on the search engine's algorithms.
