What is an LLM Brand Audit? #

An LLM Brand Audit shows how AI systems answer real customer questions in your category. BrandLM runs your prompts across major AI answer engines, measures whether your brand and competitors are mentioned, analyzes sentiment and citations, then turns the results into a report your team can act on.

Is this a dashboard or a one-time report? #

BrandLM starts as a one-time audit, not another dashboard subscription. Each report is a dated snapshot of how AI answers today. You can keep it, share it, and rerun the same audit later to measure progress after your SEO, content, PR, or GEO work.

Why not track AI visibility every day? #

For most brands, AI visibility does not change meaningfully from one day to the next. Real improvement usually takes 3–4 months of content, citation, SEO/GEO, and positioning work. BrandLM is built around that reality: run a deep audit, understand what is broken, focus on fixing it, then rerun the report after a meaningful period to see what changed. Less dashboard watching, more actual improvement.

Which AI platforms are covered? #

BrandLM currently audits answers across ChatGPT, Claude, Perplexity, Google AI Overview, and Google AI Mode. The platform is designed so additional AI answer engines can be added as needed for specific reports.

What do I receive? #

You receive a shareable report link and the full raw dataset in CSV format. The report gives your team a clear summary of the audit, while the CSV lets you dig deeper, filter prompts, check individual answers, and run your own analysis.

Each audit includes brand and competitor visibility metrics, sentiment analysis, prompt-level results, citation sources, and key patterns from the data. Higher-touch reports can also include analyst commentary and a prioritized action plan.

Is this useful for agencies? #

Yes. Agencies can use BrandLM to deliver AI visibility audits for prospects and clients using real prompt-level data, clear visuals, and client-friendly reporting.

The report makes it easy for clients to understand how their brand performs across AI answers, where competitors are winning, which sources are being cited, and what actions they should take next. It can support GEO/AEO strategy, content planning, competitive analysis, and client reporting.

Can I compare my brand against competitors? #

Yes. You can add your competitors before the audit, and BrandLM will compare your brand against them across prompts, AI platforms, mentions, sentiment, and citations.

You will see where competitors are being recommended, which prompt categories they win, and what sources may be helping them appear more often.
