# Brand Mentions vs. Backlinks: The Ahrefs 75K Brand Study

The Ahrefs 75K Brand Study (May/December 2025) analyzed brands with Domain Rating above 40 and discovered that brand mentions correlate 3x more strongly with AI visibility than backlinks. YouTube mentions are the strongest single predictor at r=0.737, while traditional backlinks only reach r=0.218.

## Key takeaways

- YouTube mentions are the strongest predictor for AI visibility (r=0.737)
- Branded web mentions: r=0.656-0.709
- Backlinks correlate only at r=0.218, 3x weaker than brand mentions
- 10X multiplier: Top quartile receives 169 vs. 14 median AI mentions
- 96% of AI citations come from earned media, not from own domains
- Only 11% of ChatGPT citations link to the brand being discussed itself
- Share of Model (SoM) is the new metric: How often, prominently, and positively a brand appears

The Ahrefs 75K-Brand Study fundamentally changed geo-understanding. [Brand Mentions, not backlinks, are the strongest predictor of AI visibility](/en/knowledge-base/seo-geo/off-page-seo-link-building/ai-citation-optimization-how-llms-select-brands-to-mention).

## The Correlation Hierarchy

The December 2025 expansion across ChatGPT, Google AI Mode, and AI Overviews delivered the field's most important insight. YouTube mentions correlate strongest at r=0.737. YouTube mention [impressions](/en/glossary/impressions) follow at r=0.717. Branded Web Mentions reach r=0.656-0.709. Branded Anchors sit at r=0.511-0.628. Branded Search Volume at r=0.352-0.466. Domain Rating at r=0.266-0.326. And backlinks, the most important traditional [SEO](/en/glossary/seo) factor, only r=0.218.

## The 10X Multiplier

Brands in the top quartile for web mentions receive 10 times more [AI](/en/glossary/ai) Overview mentions than the next quartile: 169 versus 14 at the median. Cross-platform overlap ranges from 0.749 to 0.821, meaning the same major brands dominate all AI platforms.

## Earned Media Dominates

[96 percent of AI citations come from Earned Media, not brand-owned domains](https://hbr.org/topic/subject/ai-and-machine-learning). Only 11 percent of ChatGPT citations link back to the brand being discussed. Brands investing exclusively in on-site optimization miss 85 percent of citation surface area.

## Share of Model as New Metric

The INSEAD/Jellyfish research (Harvard Business Review, June 2025) formalized Share of Model (SoM) as a metric, coined by Jack Smyth, Chief Solutions Officer at Jellyfish. SoM measures how often, prominently, and positively a brand appears in AI responses. Their finding: there is no page two with LLMs, brands are either in the consideration set or don't appear at all.

## Strategic Implication

Priority shifts from on-site to off-site: [YouTube presence (breadth more important than reach), Reddit engagement, G2/Capterra reviews, industry publications, and PR placements are the new backlinks of the AI era](/en/services/social-media-management).

## FAQ

### What is the Ahrefs 75K Brand Study?

The Ahrefs 75K Brand Study is an analysis of 75,000 brands with a Domain Rating above 40. It used Spearman correlation to examine which search and brand signals correlate with brand mentions in AI search systems. Key finding: brand mentions on the web correlate at 0.664, approximately three times as strongly with AI visibility as backlinks at 0.218.
### Are brand mentions more important than backlinks for AI visibility?

For visibility in AI search systems, yes. In the Ahrefs study, brand mentions correlate at 0.664 significantly more strongly with AI citations than backlinks at 0.218, roughly three times as strong. Language models derive brand understanding from word context and co-occurrence, which is why even unlinked mentions are a strong signal. Backlinks remain relevant for traditional SEO but lose explanatory power in the AI world.
### Why are YouTube mentions so important for AI visibility?

In the Ahrefs analysis across three AI systems, YouTube mentions at around 0.737 are the strongest individual signal for AI visibility, even ahead of branded web mentions. A plausible reason is that Google and its AI systems directly process YouTube transcripts where brands are mentioned in plain text. B2B companies should anchor expertise as video with clear mention of brand, product, and topics.
### What is Share of Model?

Share of Model, also called Share of Citation, describes how often, how prominently, and how positively a brand appears in AI responses relative to competitors. It is measured by mention frequency for a fixed prompt set, the share of own citations, the cited sources, tonality, and coverage across ChatGPT, Perplexity, AI Overviews, and AI Mode.
### Is GEO worthwhile despite low AI traffic volumes?

Yes, because the value per visit is high. At Ahrefs, 0.5 percent of traffic from AI search generated 12.1 percent of all signups, with a conversion rate roughly 23 times higher than organic search traffic. Semrush quantifies the average AI visitor as 4.4 times more valuable. For B2B with high contract values, even a few highly qualified visitors justify the investment.
### Do I need an llms.txt for good AI visibility?

An llms.txt is a proposed standard but not a broadly supported, binding mechanism by major AI providers. It can provide structure but does not replace brand signals. Since brand mentions correlate roughly three times more strongly with AI visibility than backlinks, and 85.5 percent of citations come from earned media, the leverage lies in building mentions, video presence, and citable content, not in a technical file.
### What should German-speaking B2B brands do now specifically?

First, strengthen brand signals: build presence in relevant German-language trade media, actively seek unlinked mentions, and anchor expertise as YouTube video with clear brand mention. In parallel, create citable on-page content with front-loading and documented statistics, then measure Share of Model and AI referral conversion in GA4. AI search adoption is already high in the DACH region: in Germany, 50 percent of internet users aged 16+ use AI chats at least occasionally; in Austria, around 70 percent use an AI service at least rarely.
