Yes—independent mentions can influence whether AI answer engines surface a brand, and publishing more pages on your own site may not be enough. But the evidence does not show that earned coverage always beats owned content. The practical approach is to build credible, useful information on your site, seek accurate corroboration from independent sources, and measure what different AI systems actually mention and cite.
What the GEO experiments do—and don’t—show
Search Engine Land’s report, “Two GEO experiments challenge conventional AI visibility advice,” describes tests that led its author to rethink a recommendation to publish owned-site listicles. The available excerpt says that, in the first case, recent data, current references and visible publication dates were associated with stronger citation performance. It also says the first experiment involved an existing consulting client, ran over several months and cost thousands of dollars.

Those details are not enough to establish that third-party mentions caused the improvement or that outside coverage will outperform a company’s pages in other situations. The full report’s methods and results could not be verified: the excerpt does not give the sample size, prompts, platforms, comparison group, effect sizes or geographic scope. It also does not provide enough detail to assess the second experiment separately. Treat this report as a reason to question blanket advice—not as proof of a universal ranking rule.

A controlled comparison found a preference for independent sources
A 2025 preprint by Mahe Chen, Xiaoxuan Wang, Kaiwen Chen and Nick Koudas reports large-scale controlled experiments across multiple verticals, languages and query paraphrases. The authors found that the AI search services they tested relied more on authoritative earned media than on brand-owned and social sources. They also reported differences between systems in source diversity, freshness, cross-language stability and sensitivity to prompt wording. The paper, “Generative Engine Optimization: How to Dominate AI Search,” was submitted to arXiv on September 10, 2025; as a preprint, it is evidence from a particular study, not a settled rule for every engine or query.

A large visibility dataset still found many corporate-site citations
A separate 2026 preprint analyzed more than 100,000 prompt responses across more than 100 brands tracked by Ranqo from March through May 2026. Its reported figures show why “owned content does not matter” is too simple:
| Measure | Reported result and scope |
|---|---|
| First-run brand visibility | 73% for global household-name brands, 44% for established mid-market or regional brands, and 11% for niche or small brands in Ranqo-tracked responses from March–May 2026. |
| Corporate websites among cited sources | About 78% in the same study’s dataset. The figure describes citations; it does not show that a brand controlled every cited corporate site or that those citations caused the brand to be mentioned. |
| Ranked “best-of” listicles | About 21% of citations in the same dataset were associated with ranked “best-of” listicles. This does not establish that publishing a listicle will earn a citation. |
| Sentiment framing versus mention | The authors report sentiment framing flipped about 6.7 times more often than whether a brand was mentioned in their tracked responses. |
These are findings from Pratyush Kumar’s preprint, “Generative Engine Optimization at Scale: Measuring Brand Visibility Across AI Search Engines,” submitted June 18, 2026. Its figures describe that study’s collection and definitions, not universal rates for current AI search. The study’s corporate-site citation share is a reminder that owned pages can remain useful source material; citation frequency alone does not prove that those pages made a brand visible.
Why mentions and citations are different outcomes
An AI answer can name a company without citing it, cite a page without recommending the company, or recommend it while describing it inaccurately. Those outcomes matter for different reasons: a mention affects whether a user sees the name; a citation shows which source the answer presents; a recommendation can influence a choice; and accuracy determines whether the answer represents the business correctly.

Owned pages, meanwhile, let a company publish detailed, current information directly. Neither source type guarantees inclusion, and a citation is not evidence by itself that a particular page caused a mention or recommendation.
How to balance owned content with independent coverage
Make owned pages useful source material
- Publish clear, specific information about what the company offers, who it serves and what distinguishes its products or services.
- Keep factual details and references current, and make publication or update dates visible where they help readers judge freshness. These are characteristics associated with stronger citation performance in the limited Search Engine Land excerpt, not a guaranteed tactic.
- Use pages that answer real customer questions rather than producing listicles solely in the hope of appearing in AI answers. The 2026 dataset shows listicles among cited sources, but does not establish that creating one causes visibility.
Seek independent corroboration, not just more mentions
Consider where relevant audiences already look for trustworthy information: independent publishers, reviews, professional or institutional sources, and communities. Aim for accurate, substantive coverage that can stand on its own. The 2025 controlled-comparison preprint supports taking authoritative third-party sources seriously, but it does not show that any particular placement, review or community mention will lead to a citation.
Keep the two workstreams connected: the company’s site should be an accurate reference for its own facts, while outside sources provide independent perspectives. The evidence supports a portfolio, not a choice between publishing on your site and earning coverage elsewhere.

How to measure AI visibility without confusing the metrics
Because the studies use different engines, prompts and measures, a useful GEO check should compare like with like. Treat the following as a measurement framework, not a proven intervention:
Recommended Free Tools
- Choose a fixed set of realistic prompts. Include the questions customers ask at different stages, such as discovering options, comparing providers and asking for a recommendation. Keep the wording stable between measurement rounds, and record any prompt changes.
- Check each engine separately and repeat runs. Record the platform and date. A result on one system or in one response does not establish a pattern across engines.
- Track distinct outcomes. Note whether the brand is named, cited, recommended and accurately described. Record sentiment or framing separately; the 2026 preprint indicates that framing can change even when mention status does not.
- Log the sources and their order. Capture which pages are cited and where they appear in the answer. Identify whether each source is company-owned or independent, and note its publisher and visible date.
- Compare by query intent and brand category. Do not collapse discovery prompts, comparisons and recommendation questions into one score. Interpret results in light of the brand’s maturity: the 2026 study reported substantially different first-run visibility across its brand groups.
- Use results to choose what to improve. If the answer omits a brand, misstates a fact or relies on outdated information, investigate the relevant owned page and the independent sources appearing in that response. Recheck with the same prompts and engines after changes; do not assume a placement or page update will cause a particular AI result.
What a sensible conclusion looks like
The strongest case for earned mentions is not that owned content has become irrelevant. It is that AI answers draw on sources beyond a company’s site, and one controlled-comparison preprint found a preference for authoritative third-party material in the systems it tested. The counterweight is substantial: a 2026 visibility study reported that corporate websites accounted for about 78% of its citations. The sensible GEO strategy is therefore to maintain useful, current owned information, build credible independent corroboration, and judge performance by repeated, engine-specific observations rather than by a single mention or citation.
