TL;DR

Master 내돈내산 and 광고 to spot real Korean product reviews. Learn the nuance behind 'my own money' vs. sponsored content with this guide.

If you are scrolling through a Korean YouTuber's video description or a Naver Blog post about a new skincare product, you will almost certainly see the hashtag #내내산. It is the ultimate 'Trust Meter' in the Korean digital economy, used to prove that the creator isn't just reading a script from a brand.

Quick cheat sheet

Expressions in this post

내돈내산 - bought with my own money
#1slangLv 2
내돈내산
naedonnaesan
bought with my own money

Quick meaning

An abbreviation of 내 돈 주고 내가 산nae don jugo naega san (I gave my money and I bought it).

Nuance (how it feels)

It feels like a shield against skepticism. In 2020, Korea was rocked by the 'Backdoor Ad' (뒷광고) scandal where influencers hid sponsorships. Now, 내돈내산naedonnaesan is a proud declaration of consumer independence. It implies: "I am going to be brutally honest because I spent my hard-earned cash on this."

Common trap (misunderstanding)

Don't use this if you received a discount or a 'review sample' even if you didn't get paid cash. If any part of the transaction wasn't 100% your own retail-price spending, using this tag can lead to a 'call-out' from savvy Korean netizens.

Tone ladder (risky → safer)

  1. 내돈내산naedonnaesan (Casual/Social media standard)
  2. 직접 구매한 후기입니다jikjeop gumaehan hugiipnida (Polite/Formal blog style)
  3. 본 포스팅은 대가 없이 작성되었습니다bon poseutieun daega eopsi jakseongdoeeotseupnida (Professional/Legalistic)

Minimal pairs (A vs B)

  • 내돈내산naedonnaesan: Focuses on the source of the money (Me).
  • 솔직후기soljikhugi: Focuses on the quality of the opinion (Honest), but could still be a sponsored product.

Examples (chat)

광고 - advertisement
#2slangLv 1
광고
gwang-go
advertisement

Quick meaning

Advertisement or paid promotion.

Nuance (how it feels)

On social media, it is often tagged as #유료광고포함#yuryogwanggopoham (Includes paid advertisement). While necessary for transparency, it often signals to viewers that the content might be biased or overly polished.

Common trap (misunderstanding)

In gaming or YouTube comments, people shout 광고네gwanggone (It's an ad) as a joke when someone praises something too much, even if it's not actually a paid post.

Tone ladder (risky → safer)

  1. 광고gwanggo (Neutral/Direct)
  2. 협찬hyeopchan (Sponsorship - sounds slightly more 'partnership' focused)
  3. PPL (Used specifically for product placement in dramas/shows)

Minimal pairs (A vs B)

  • 광고gwanggo: Direct payment involved.
  • 협찬hyeopchan: Often means the product was provided for free, but no extra cash was paid for the shoutout.

Examples (chat)

이 영상 광고인가요?i yeongsang gwanggoingayo? — Is this video an advertisement?

이 포스팅은 유료 광고를 포함하고 있습니다.
i poseutieun yuryo gwanggoreul pohamhago itseupnida.
This post contains paid advertisements.
광고 좀 그만 보고 싶어.
gwanggo jom geuman bogo sipeo.
I want to stop seeing so many ads.

The Trust Decision Tree

  • Did you pay 100% of the price? → Use 내돈내산naedonnaesan
  • Did the brand send it for free? → Use 협찬hyeopchan (Sponsorship)
  • Did you get paid to make the post? → Use 광고gwanggo (Ad)
