How to say "affiliate" in Japanese

• アフィリエイトCommon
  nounCovers the affiliate-marketing sense of 'affiliate', as in earning commissions by promoting products. A loanword, this is the common word for internet and business contexts. It does not mean an affiliated company.
• アフィリ
  nounA shorter form of アフィリエイト with the same affiliate-marketing sense. Since it is less common and simply an abbreviation, it is normally better to write the full term.
• 加入者かにゅうしゃ
  nounMeans a person who has joined or subscribed — a member, entrant, or participant — so 'affiliate' here reads as 'one who affiliates (with an organization)'. It is a marginal match for 'affiliate' and usually 'member' is the intended meaning.
• 関係団体かんけいだんたい
  nounRefers to an affiliated or related organization, as in corporate or institutional group relations. Use it when 'affiliate' means a company or organization connected to a larger one.
• 関係先かんけいさき
  nounMeans a related party or affiliated contact, such as a business counterpart. Suitable when 'affiliate' refers to an affiliated company or organization, though it can shade toward the neutral 'related party'.

Choose 「アフィリエイト」 for the marketing/business-program sense, 関係団体 or 関係先 for an affiliated company or organization, and 加入者 only for a person who has joined something.
