TL;DR

• No brand in the 103-brand index converts mentions into citations of its own site at better than 15%. The ceiling is shared by KT and KB Kookmin Bank.
• Eight of the nine best-converting brands are financial: banks, brokerages, insurers, and card issuers. The only exception is KT.
• The most-mentioned consumer brands, LG Electronics (67%), Xiaomi (64%), Hyundai Motor (57%), are cited at 0–1%.
• External blogs are 45.4% of all 50,160 citations, more than double the 19.5% that go to brands' own official sites, which is why even the best converter tops out at 15%.

Getting mentioned by AI and getting cited by AI are not the same thing, and in W21 the brands that win the second are almost all financial.

Across all 11 industries we track, 50,160 citations were classified in W21. Sorted by how often AI cites a brand's own website, the leaderboard tops out at 15%, and it is shared by exactly two brands: KT and KB Kookmin Bank. No brand in the index, in any industry, converts more than 15% of its AI responses into a citation of its own domain.

That ceiling matters less than who sits under it. Of the nine brands that clear a 10% own-site citation rate, eight are financial: banking, securities, insurance, and credit cards. The lone exception is KT. Meanwhile the brands AI talks about most, LG Electronics, Xiaomi, Hyundai Motor, are cited at essentially zero. Mentions and citations are running on two different tracks, and only one of them rewards consumer brands.

How AI is sourcing its answers

Every week, we run a fixed set of consumer-style prompts through the three AI surfaces Korean consumers actually use: Google AI Overviews (AIO), Naver AI Briefing (AIB), and ChatGPT. For each response we record which brand was mentioned, which URL the AI surfaced as a source, what type of domain that URL belongs to (the brand's own official site, an external blog, news, video, etc.), and, independently, what type of content the page itself is.

The reason citation rates are low everywhere shows up in the all-industry domain mix. Across the full 50,160 W21 citations:

When AI cites a source, nearly half the time (45.4%) it is an external blog. A brand's own official site is a distant second at 19.5%, less than half the external-blog share. That gap is the structural reason own-site citation rates are low for everyone: most of the links AI hands out go to third parties, not to the brands themselves. The question is which brands manage to beat the average and pull AI back to their own domain, and they are not a random spread.

What wins in each industry

Below are the nine brands with the highest own-site citation rate in W21 (the brands AI is most likely to link directly), with their mention rate alongside. The two co-leaders at 15% are highlighted.

Even the index's best converters top out at 15%. KT and KB Kookmin Bank tie for first, and they reach it from opposite directions: KT is mentioned in 69% of telecom responses, KB Kookmin in 48% of banking responses, yet both convert at the same 15%. Below them the list is monochrome: two banks (KB Kookmin 48% / 15%, Woori 44% / 10%), three brokerages (Samsung Securities 58% / 12%, Korea Investment 62% / 11%, Mirae Asset 62% / 10%), two insurers (Samsung Fire & Marine 57% / 11%, KB Insurance 51% / 10%), and one card issuer (Hyundai Card 43% / 10%). Eight of these nine brands are financial. KT is the only one that is not.

The pattern inverts at the top of the mention table. The brands AI names most are consumer brands that it barely links. LG Electronics is mentioned in 67% of appliance responses but cited at 0%. Xiaomi (64%) is at 0%, Hyundai Motor (57%) at 0%, and Kia (60%) at 1%. These are the largest mention-vs-citation gaps in the index. LG Electronics alone is a 67-point gap. AI has plenty to say about appliances and cars; it just sources those answers from somewhere other than the manufacturer's website.

The split is not about how famous a brand is. LG Electronics and Samsung Securities are both household names. It is about where the authoritative information lives. For a brokerage or a bank, the canonical numbers (rates, fees, product terms, disclosures) sit on the brand's own domain, and AI treats those pages as the source of record. For an appliance or a car, the comparison a consumer wants is assembled by a third-party reviewer, so that is where AI goes.

What this means for AI visibility budgets

Three implications follow directly from W21's citation data.

A high mention rate buys you nothing on its own. LG Electronics, Xiaomi, and Hyundai Motor are mentioned in 57–67% of their category's responses and cited at 0–1%. Being named often does not produce a single link back to your site. "Increase how often AI names us" and "Increase how often AI cites our website" are separate targets that respond to different inputs, and the second is the one that drives traffic and trust. Budget them separately.

Citations follow authoritative, structured, on-domain data. Eight of the nine best-converting brands in the index are financial because rates, terms, and disclosures are canonical reference data that lives, and is trusted, on the brand's own site. Only 19.5% of all citations go to brands' own domains, but the brands that publish reference-grade content capture a disproportionate share of that 19.5%. The lesson is not "be a bank"; it is "own the canonical version of the facts in your category."

Consumer-electronics and automotive brands are leaving links on the table. The most-mentioned brands in those categories convert at 0–1% because the spec sheets, comparisons, and buying guides AI relies on are published by review blogs, and external blogs are 45.4% of all citations. A manufacturer that puts the definitive, structured spec-and-comparison data on its own domain is competing for citations that currently default to third parties. The mentions are already there; the citations are unclaimed.

What we'll publish each week

AI Visibility Weekly publishes every Monday. We track 103 Korean enterprise brands across 11 industries (660 prompts per week, 50,160 classified citations in W21) and pull out the single most meaningful shift in how AI is talking about them. Week 01 gave the all-industry source distribution, Week 02 surfaced the curation concentration in credit cards, Week 03 framed the mention-citation gap in Korean telecom, Week 04 marked Banking's debut, and this Week 05 shows where citations actually land across the whole index.

The newsletter is the digest, the blog is the analysis. Both are free, and they run alongside the public Enterprise AI Visibility Index where readers can find their own brand at any time.

The question to take into the week from Issue 05 is direct. If AI mentions your brand constantly but cites your competitors' financial-grade reference pages instead of yours, what would it take to make your own domain the canonical source in your category?

FAQ

Why does AI cite some brands' own websites but almost never others?

When AI cites a source, only 19.5% of all citations point to a brand's own official site, while 45.4% point to external blogs. Brands whose own domains host authoritative, structured reference data (rates, terms, policy details) get cited more, and those are overwhelmingly financial. Even so, the best own-site citation rate anywhere in the 103-brand index is 15%, shared by KT and KB Kookmin Bank.

Which brands convert mentions into citations of their own site best?

KT and KB Kookmin Bank lead the index at 15%, followed by Samsung Securities at 12%, then Korea Investment & Securities and Samsung Fire & Marine at 11%. Eight of the nine brands above the 10% line are financial: two banks, three brokerages, two insurers, and one card issuer. KT is the only non-financial brand in that group.

Why are LG Electronics and Hyundai Motor mentioned so often but cited so rarely?

LG Electronics is mentioned in 67% of appliance responses but cited at 0%. Xiaomi (64%) is also at 0%, Hyundai Motor (57%) at 0%, and Kia (60%) at 1%. The product information AI draws on for these categories lives mostly on third-party review and spec blogs (external blogs make up 45.4% of all citations) rather than on the brands' own domains.

Is a high mention rate enough for AI visibility?

No. Mention rate and own-site citation rate move on independent axes. The most-mentioned consumer brands in W21 convert at 0–1%, while the brands that actually earn citations of their own site are concentrated in finance. Getting named often and getting linked are two separate outcomes that need separate work.

Which AI surfaces does this data cover?

Three: Google AI Overviews (AIO), Naver AI Briefing (AIB), and ChatGPT. We run a fixed set of consumer-style prompts through all three every week and classify the URLs each surface returns by both domain type and content type.

How often is this report updated?

Every Monday. The data covers 103 Korean enterprise brands across 11 industries (660 prompts and 50,160 classified citations in W21). The latest snapshot covers W17 to W21.
