Adverum launches AI visibility audit for U.S. companies

Adverum has introduced a 10-business-day audit for U.S. companies that maps how AI assistants like ChatGPT describe a business, which sources they cite and where they get facts wrong. The service is designed to help communications teams improve how their companies show up in AI-generated answers without promising rankings.

Why it matters: - Buyers, journalists and job candidates are increasingly using AI assistants for company research before visiting a website. - Adverum is framing AI visibility as a reputation issue, not just a technical SEO problem. - The audit is designed to help companies correct inaccurate AI answers and strengthen the sources those systems rely on.

What happened: - Adverum, an independent strategic communications agency founded in Vilnius in 2004, launched the Adverum AI Visibility Audit for U.S. companies. - The audit tests how ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews answer questions about a company, its competitors and its category. - The service is delivered remotely by Adverum consultants.

The details: - The audit runs 30 to 40 buyer-style prompts in clean, logged-out sessions. - Key prompts are repeated, and every answer is logged with a screenshot. - Each answer is checked against a verified fact sheet to flag outdated or incorrect statements. - A source map shows which publications, directories and platforms AI systems cite for competitors but not for the client. - A technical review covers robots.txt access for AI search crawlers, structured data and business listings such as Wikidata. - Clients receive prioritized recommendations and a retest after 90 days using the same prompts. - The audit takes 10 business days and costs between $950 and $2,450, depending on the number of markets and competitors. - Adverum says the audit does not guarantee placement in AI answers and does not create fake reviews, undisclosed paid content or inauthentic encyclopedia edits. - Results are reported as dated snapshots rather than statistical measurements because AI answers change over time. - The audit is intended for U.S. companies whose buyers research suppliers online before contacting them, and for communications teams that need evidence of how AI systems describe their organization. - More information and audit requests are available in Adverum’s announcement.

Between the lines: - The launch reflects a broader shift from traditional search visibility to visibility inside AI-generated answers. - Adverum is positioning source quality and media coverage as central inputs to AI results. - The agency is also signaling caution by avoiding promises of rankings in systems it cannot control. - In support of that point, Adverum cited Muck Rack’s Generative Pulse study published in May 2026, which found journalism accounted for 27% of cited links across more than 25 million links cited by ChatGPT, Claude and Gemini, while paid and advertorial content accounted for 0.3%.

What's next: - Clients receive a retest 90 days after the initial audit to compare changes in AI answers. - Adverum will continue to present the results as time-stamped snapshots, not permanent rankings. - Companies that want more accurate AI descriptions will need to keep updating the sources those systems draw from.

The bottom line: - Adverum is selling a new kind of communications audit for the AI era: measure what assistants say, find the source gaps and fix the facts that shape the answer.
