Why there are no Variations for some Keywords

Sometimes a keyword phrase does not have any variations. Variations are often the plural form of your keyword, a very close synonym, or a component part of your keyword phrase. Some languages don’t have plural forms, and variations will be less likely in those languages. And sometimes there are no synonyms for a keyword: for example when your keyword is an acronym, a technical phrase, or a product number.
