Building brand authority for large language models requires a different investment mix than traditional search authority. This survey of 1,000 marketers rates eight authority-building factors on a five-point importance scale, and the results reveal a clear hierarchy: customer reviews and content creation are rated as critical by the largest shares of respondents, while backlinks and executive thought leadership trail significantly. The distribution reflects practitioner beliefs about what LLMs weigh when forming brand representations, though those beliefs are informed rather than empirically verified.

Essential Statistics

• Customer reviews are rated critical by 82 percent of respondents and very important or critical combined by 94 percent, the highest importance rating in the dataset.
• Content creation is rated critical by 64 percent and very important or critical combined by 93 percent of respondents.
• AI citations and mentions are rated critical by 53 percent and very important or critical combined by 80 percent of respondents.
• Earned media and press coverage is rated critical by 33 percent and very important or critical combined by 65 percent.
• Original research is rated critical by only 14 percent, with 46 percent rating it moderately important.
• Backlinks are rated not important or slightly important by 70 percent of respondents, and executive thought leadership by 70 percent as well, the lowest importance ratings in the dataset.

Key Takeaways

• Customer reviews rated as critical by 82 percent of practitioners reflects a belief that LLMs weigh social proof signals heavily when forming brand representations. This is consistent with how language models trained on web data absorb sentiment and validation signals from review platforms, forums, and consumer-generated content.
• The low importance rating for backlinks at 70 percent not important or slightly important is a significant departure from traditional SEO signal rankings and reinforces the pattern seen in the AI visibility signals data. Practitioners increasingly believe that LLM authority is built through reputation signals rather than link equity.
• Original research rating as moderately important by 46 percent rather than critical may reflect that its primary value is in earning the higher-rated signals above it, including citations, media coverage, and brand mentions, rather than being a direct authority signal itself.
• Executive thought leadership rating low alongside backlinks challenges the conventional wisdom that personal brand building for executives directly transfers to brand authority in AI systems. Practitioners appear to believe the relationship is less direct than many assume.
• This data represents practitioner beliefs about how LLMs work, not measured signal weights from AI platform documentation. The actual mechanisms by which LLMs form brand representations involve complex training dynamics that are not fully transparent.

Actionable Insights

• Build a systematic review acquisition program as a foundational LLM authority investment. The near-unanimous belief that customer reviews are critical or very important for LLM brand authority makes this one of the highest-consensus actions available. Automating review requests across your major review platforms produces compounding authority signal over time at relatively low ongoing cost.
• Treat content creation as an ongoing authority investment rather than a campaign-level activity. The 93 percent very important or critical rating for content creation confirms that consistent, quality publishing is viewed as foundational to LLM brand authority. Frequency and freshness of content output, not just quality, appear to matter based on how LLM training data is weighted toward recent and frequently updated sources.
• Build AI citation and mention monitoring into your regular reporting before investing heavily in activities designed to generate those mentions. The 80 percent very important or critical rating for AI citations and mentions confirms their perceived importance, but you need a baseline measurement of your current citation share to evaluate whether any investment is producing results.
• Approach earned media as a brand authority investment rather than just a PR activity. The 65 percent very important or critical rating for earned media and press coverage positions media outreach as a GEO investment. Prioritizing placements in publications that AI platforms are known to draw from, including major industry publications, news outlets, and credible blogs, may produce more LLM authority impact than less selective media outreach.
• Do not abandon executive thought leadership programs if they serve other business purposes, but adjust expectations about their direct contribution to LLM brand authority. The low importance rating suggests practitioners believe the connection between executive content and LLM brand representation is less reliable than the higher-rated factors. It may contribute indirectly through the brand mentions and coverage it generates rather than being a primary authority signal itself.

Customer reviews at 82 percent critical and backlinks at 70 percent not important or slightly important. That inversion from traditional SEO thinking is the central finding here. Whether LLMs actually weight these signals this differently is something practitioners believe based on observation rather than verified documentation. But when a thousand marketers agree that reviews matter more than links for AI authority, that consensus is worth acting on.’ – Neil Patel
